+## Zustand Store Testing
+
+### Global Zustand Mock (Auto-loaded)
+
+Zustand is globally mocked in `web/vitest.setup.ts` following the [official Zustand testing guide](https://zustand.docs.pmnd.rs/guides/testing). The mock in `web/__mocks__/zustand.ts` provides:
+
+- Real store behavior with `getState()`, `setState()`, `subscribe()` methods
+- Automatic store reset after each test via `afterEach`
+- Proper test isolation between tests
+
+### ✅ Recommended: Use Real Stores (Official Best Practice)
+
+**DO NOT mock store modules manually.** Import and use the real store, then use `setState()` to set test state:
+
+```typescript
+// ✅ CORRECT: Use real store with setState
+import { useAppStore } from '@/app/components/app/store'
+
+describe('MyComponent', () => {
+  it('should render app details', () => {
+    // Arrange: Set test state via setState
+    useAppStore.setState({
+      appDetail: {
+        id: 'test-app',
+        name: 'Test App',
+        mode: 'chat',
+      },
+    })
+
+    // Act
+    render(<MyComponent />)
+
+    // Assert
+    expect(screen.getByText('Test App')).toBeInTheDocument()
+    // Can also verify store state directly
+    expect(useAppStore.getState().appDetail?.name).toBe('Test App')
+  })
+
+  // No cleanup needed - global mock auto-resets after each test
+})
+```
+
+### ❌ Avoid: Manual Store Module Mocking
+
+Manual mocking conflicts with the global Zustand mock and loses store functionality:
+
+```typescript
+// ❌ WRONG: Don't mock the store module
+vi.mock('@/app/components/app/store', () => ({
+  useStore: (selector) => mockSelector(selector),  // Missing getState, setState!
+}))
+
+// ❌ WRONG: This conflicts with global zustand mock
+vi.mock('@/app/components/workflow/store', () => ({
+  useWorkflowStore: vi.fn(() => mockState),
+}))
+```
+
+**Problems with manual mocking:**
+
+1. Loses `getState()`, `setState()`, `subscribe()` methods
+1. Conflicts with global Zustand mock behavior
+1. Requires manual maintenance of store API
+1. Tests don't reflect actual store behavior
+
+### When Manual Store Mocking is Necessary
+
+In rare cases where the store has complex initialization or side effects, you can mock it, but ensure you provide the full store API:
+
+```typescript
+// If you MUST mock (rare), include full store API
+const mockStore = {
+  appDetail: { id: 'test', name: 'Test' },
+  setAppDetail: vi.fn(),
+}
+
+vi.mock('@/app/components/app/store', () => ({
+  useStore: Object.assign(
+    (selector: (state: typeof mockStore) => unknown) => selector(mockStore),
+    {
+      getState: () => mockStore,
+      setState: vi.fn(),
+      subscribe: vi.fn(),
+    },
+  ),
+}))
+```
+
+### Store Testing Decision Tree
+
+```
+Need to test a component using Zustand store?
+│
+├─ Can you use the real store?
+│  └─ YES → Use real store + setState (RECOMMENDED)
+│           useAppStore.setState({ ... })
+│
+├─ Does the store have complex initialization/side effects?
+│  └─ YES → Consider mocking, but include full API
+│           (getState, setState, subscribe)
+│
+└─ Are you testing the store itself (not a component)?
+   └─ YES → Test store directly with getState/setState
+            const store = useMyStore
+            store.setState({ count: 0 })
+            store.getState().increment()
+            expect(store.getState().count).toBe(1)
+```
+
+### Example: Testing Store Actions
+
+```typescript
+import { useCounterStore } from '@/stores/counter'
+
+describe('Counter Store', () => {
+  it('should increment count', () => {
+    // Initial state (auto-reset by global mock)
+    expect(useCounterStore.getState().count).toBe(0)
+
+    // Call action
+    useCounterStore.getState().increment()
+
+    // Verify state change
+    expect(useCounterStore.getState().count).toBe(1)
+  })
+
+  it('should reset to initial state', () => {
+    // Set some state
+    useCounterStore.setState({ count: 100 })
+    expect(useCounterStore.getState().count).toBe(100)
+
+    // After this test, global mock will reset to initial state
+  })
+})
+```

Triggers when creating new API contracts, adding service endpoints, integrating TanStack Query with typed contracts, or migrating legacy service calls to oRPC. Use for all API layer work in web/contract and web/service directories.
+---
+
+# oRPC Contract-First Development
+
+## Project Structure
+
+```
+web/contract/
+├── base.ts           # Base contract (inputStructure: 'detailed')

+└── console/          # Console contracts by domain
+    ├── system.ts
+    └── billing.ts
+```
+
+## Workflow
+
+1. **Create contract** in `web/contract/console/{domain}.ts`
+   - Import `base` from `../base` and `type` from `@orpc/contract`
+   - Define route with `path`, `method`, `input`, `output`
+
+2. **Register in router** at `web/contract/router.ts`
+   - Import directly from domain file (no barrel files)
+   - Nest by API prefix: `billing: { invoices, bindPartnerStack }`
+
+3. **Create hooks** in `web/service/use-{domain}.ts`
+   - Use `consoleQuery.{group}.{contract}.queryKey()` for query keys
+   - Use `consoleClient.{group}.{contract}()` for API calls
+
+## Key Rules
+
+- **Input structure**: Always use `{ params, query?, body? }` format
+- **Path params**: Use `{paramName}` in path, match in `params` object
+- **Router nesting**: Group by API prefix (e.g., `/billing/*` → `billing: {}`)
+- **No barrel files**: Import directly from specific files
+- **Types**: Import from `@/types/`, use `type<T>()` helper
+
+## Type Export

+description: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
+---
+
+# Skill Creator
+
+This skill provides guidance for creating effective skills.
+
+## About Skills
+
+Skills are modular, self-contained packages that extend Claude's capabilities by providing
+specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
+domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
+equipped with procedural knowledge that no model can fully possess.
+
+### What Skills Provide
+
+1. Specialized workflows - Multi-step procedures for specific domains
+2. Tool integrations - Instructions for working with specific file formats or APIs
+3. Domain expertise - Company-specific knowledge, schemas, business logic
+4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
+
+## Core Principles
+
+### Concise is Key
+
+The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
+
+**Default assumption: Claude is already very smart.** Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this explanation?" and "Does this paragraph justify its token cost?"
+
+Prefer concise examples over verbose explanations.
+
+### Set Appropriate Degrees of Freedom
+
+Match the level of specificity to the task's fragility and variability:
+
+**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.
+
+**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.
+
+**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.
+
+Think of Claude as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).
+
+### Anatomy of a Skill
+
+Every skill consists of a required SKILL.md file and optional bundled resources:
+
+```
+skill-name/
+├── SKILL.md (required)
+│   ├── YAML frontmatter metadata (required)
+│   │   ├── name: (required)
+│   │   └── description: (required)
+│   └── Markdown instructions (required)
+└── Bundled Resources (optional)
+    ├── scripts/          - Executable code (Python/Bash/etc.)
+    ├── references/       - Documentation intended to be loaded into context as needed
+    └── assets/           - Files used in output (templates, icons, fonts, etc.)
+```
+
+#### SKILL.md (required)
+
+Every SKILL.md consists of:
+
+- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that Claude reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.
+- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).
+
+#### Bundled Resources (optional)
+
+##### Scripts (`scripts/`)
+
+Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
+
+- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed
+- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks
+- **Benefits**: Token efficient, deterministic, may be executed without loading into context
+- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments
+
+##### References (`references/`)
+
+Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
+
+- **When to include**: For documentation that Claude should reference while working
+- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications
+- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
+- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed
+- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md
+- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
+
+##### Assets (`assets/`)
+
+Files not intended to be loaded into context, but rather used within the output Claude produces.
+
+- **When to include**: When the skill needs files that will be used in the final output
+- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography
+- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
+- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context
+
+#### What to Not Include in a Skill
+
+A skill should only contain essential files that directly support its functionality. Do NOT create extraneous documentation or auxiliary files, including:
+
+- README.md
+- INSTALLATION_GUIDE.md
+- QUICK_REFERENCE.md
+- CHANGELOG.md
+- etc.
+
+The skill should only contain the information needed for an AI agent to do the job at hand. It should not contain auxilary context about the process that went into creating it, setup and testing procedures, user-facing documentation, etc. Creating additional documentation files just adds clutter and confusion.
+
+### Progressive Disclosure Design Principle
+
+Skills use a three-level loading system to manage context efficiently:
+
+1. **Metadata (name + description)** - Always in context (~100 words)
+2. **SKILL.md body** - When skill triggers (<5k words)
+3. **Bundled resources** - As needed by Claude (Unlimited because scripts can be executed without reading into context window)
+
+#### Progressive Disclosure Patterns
+
+Keep SKILL.md body to the essentials and under 500 lines to minimize context bloat. Split content into separate files when approaching this limit. When splitting out content into other files, it is very important to reference them from SKILL.md and describe clearly when to read them, to ensure the reader of the skill knows they exist and when to use them.
+
+**Key principle:** When a skill supports multiple variations, frameworks, or options, keep only the core workflow and selection guidance in SKILL.md. Move variant-specific details (patterns, examples, configuration) into separate reference files.
+
+**Pattern 1: High-level guide with references**
+
+```markdown
+# PDF Processing
+
+## Quick start
+
+Extract text with pdfplumber:
+[code example]
+
+## Advanced features
+
+- **Form filling**: See [FORMS.md](FORMS.md) for complete guide
+- **API reference**: See [REFERENCE.md](REFERENCE.md) for all methods
+- **Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns
+```
+
+Claude loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.
+
+**Pattern 2: Domain-specific organization**
+
+For Skills with multiple domains, organize content by domain to avoid loading irrelevant context:
+
+```
+bigquery-skill/
+├── SKILL.md (overview and navigation)
+└── reference/
+    ├── finance.md (revenue, billing metrics)
+    ├── sales.md (opportunities, pipeline)
+    ├── product.md (API usage, features)
+    └── marketing.md (campaigns, attribution)
+```
+
+When a user asks about sales metrics, Claude only reads sales.md.
+
+Similarly, for skills supporting multiple frameworks or variants, organize by variant:
+
+```
+cloud-deploy/
+├── SKILL.md (workflow + provider selection)
+└── references/
+    ├── aws.md (AWS deployment patterns)
+    ├── gcp.md (GCP deployment patterns)
+    └── azure.md (Azure deployment patterns)
+```
+
+When the user chooses AWS, Claude only reads aws.md.
+
+**Pattern 3: Conditional details**
+
+Show basic content, link to advanced content:
+
+```markdown
+# DOCX Processing
+
+## Creating documents
+
+Use docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).
+
+## Editing documents
+
+For simple edits, modify the XML directly.
+
+**For tracked changes**: See [REDLINING.md](REDLINING.md)
+**For OOXML details**: See [OOXML.md](OOXML.md)
+```
+
+Claude reads REDLINING.md or OOXML.md only when the user needs those features.
+
+**Important guidelines:**
+
+- **Avoid deeply nested references** - Keep references one level deep from SKILL.md. All reference files should link directly from SKILL.md.
+- **Structure longer reference files** - For files longer than 100 lines, include a table of contents at the top so Claude can see the full scope when previewing.
+
+## Skill Creation Process
+
+Skill creation involves these steps:
+
+1. Understand the skill with concrete examples
+2. Plan reusable skill contents (scripts, references, assets)
+3. Initialize the skill (run init_skill.py)
+4. Edit the skill (implement resources and write SKILL.md)
+5. Package the skill (run package_skill.py)
+6. Iterate based on real usage
+
+Follow these steps in order, skipping only if there is a clear reason why they are not applicable.
+
+### Step 1: Understanding the Skill with Concrete Examples
+
+Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
+
+To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
+
+For example, when building an image-editor skill, relevant questions include:
+
+- "What functionality should the image-editor skill support? Editing, rotating, anything else?"
+- "Can you give some examples of how this skill would be used?"
+- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
+- "What would a user say that should trigger this skill?"
+
+To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
+
+Conclude this step when there is a clear sense of the functionality the skill should support.
+
+### Step 2: Planning the Reusable Skill Contents
+
+To turn concrete examples into an effective skill, analyze each example by:
+
+1. Considering how to execute on the example from scratch
+2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
+
+Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows:
+
+1. Rotating a PDF requires re-writing the same code each time
+2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill
+
+Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
+
+1. Writing a frontend webapp requires the same boilerplate HTML/React each time
+2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill
+
+Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows:
+
+1. Querying BigQuery requires re-discovering the table schemas and relationships each time
+2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill
+
+To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
+
+### Step 3: Initializing the Skill
+
+At this point, it is time to actually create the skill.
+
+Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
+
+When creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.
+
+Usage:
+
+```bash
+scripts/init_skill.py <skill-name> --path <output-directory>
+```
+
+The script:
+
+- Creates the skill directory at the specified path
+- Generates a SKILL.md template with proper frontmatter and TODO placeholders
+- Creates example resource directories: `scripts/`, `references/`, and `assets/`
+- Adds example files in each directory that can be customized or deleted
+
+After initialization, customize or remove the generated SKILL.md and example files as needed.
+
+### Step 4: Edit the Skill
+
+When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Include information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
+
+#### Learn Proven Design Patterns
+
+Consult these helpful guides based on your skill's needs:
+
+- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic
+- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns
+
+These files contain established best practices for effective skill design.
+
+#### Start with Reusable Skill Contents
+
+To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.
+
+Added scripts must be tested by actually running them to ensure there are no bugs and that the output matches what is expected. If there are many similar scripts, only a representative sample needs to be tested to ensure confidence that they all work while balancing time to completion.
+
+Any example files and directories not needed for the skill should be deleted. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.
+
+#### Update SKILL.md
+
+**Writing Guidelines:** Always use imperative/infinitive form.
+
+##### Frontmatter
+
+Write the YAML frontmatter with `name` and `description`:
+
+- `name`: The skill name
+- `description`: This is the primary triggering mechanism for your skill, and helps Claude understand when to use the skill.
+  - Include both what the Skill does and specific triggers/contexts for when to use it.
+  - Include all "when to use" information here - Not in the body. The body is only loaded after triggering, so "When to Use This Skill" sections in the body are not helpful to Claude.
+  - Example description for a `docx` skill: "Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. Use when Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks"
+
+Do not include any other fields in YAML frontmatter.
+
+##### Body
+
+Write instructions for using the skill and its bundled resources.
+
+### Step 5: Packaging a Skill
+
+Once development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
+
+```bash
+scripts/package_skill.py <path/to/skill-folder>
+```
+
+Optional output directory specification:
+
+```bash
+scripts/package_skill.py <path/to/skill-folder> ./dist
+```
+
+The packaging script will:
+
+1. **Validate** the skill automatically, checking:
+
+   - YAML frontmatter format and required fields
+   - Skill naming conventions and directory structure
+   - Description completeness and quality
+   - File organization and resource references
+
+2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.
+
+If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
+
+### Step 6: Iterate
+
+After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
+
+**Iteration workflow:**
+
+1. Use the skill on real tasks
+2. Notice struggles or inefficiencies
+3. Identify how SKILL.md or bundled resources should be updated
+4. Implement changes and test again

+# Output Patterns
+
+Use these patterns when skills need to produce consistent, high-quality output.
+
+## Template Pattern
+
+Provide templates for output format. Match the level of strictness to your needs.
+
+**For strict requirements (like API responses or data formats):**
+
+```markdown
+## Report structure
+
+ALWAYS use this exact template structure:
+
+# [Analysis Title]
+
+## Executive summary
+[One-paragraph overview of key findings]
+
+## Key findings
+- Finding 1 with supporting data
+- Finding 2 with supporting data
+- Finding 3 with supporting data
+
+## Recommendations
+1. Specific actionable recommendation
+2. Specific actionable recommendation
+```
+
+**For flexible guidance (when adaptation is useful):**
+
+```markdown
+## Report structure
+
+Here is a sensible default format, but use your best judgment:
+
+# [Analysis Title]
+
+## Executive summary
+[Overview]
+
+## Key findings
+[Adapt sections based on what you discover]
+
+## Recommendations
+[Tailor to the specific context]
+
+Adjust sections as needed for the specific analysis type.
+```
+
+## Examples Pattern
+
+For skills where output quality depends on seeing examples, provide input/output pairs:
+
+```markdown
+## Commit message format
+
+Generate commit messages following these examples:
+
+**Example 1:**
+Input: Added user authentication with JWT tokens
+Output:
+```
+
+feat(auth): implement JWT-based authentication
+
+Add login endpoint and token validation middleware
+
+```
+
+**Example 2:**
+Input: Fixed bug where dates displayed incorrectly in reports
+Output:
+```
+
+fix(reports): correct date formatting in timezone conversion
+
+Use UTC timestamps consistently across report generation
+
+```
+
+Follow this style: type(scope): brief description, then detailed explanation.
+```
+
+Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.

+# Workflow Patterns
+
+## Sequential Workflows
+
+For complex tasks, break operations into clear, sequential steps. It is often helpful to give Claude an overview of the process towards the beginning of SKILL.md:
+
+```markdown
+Filling a PDF form involves these steps:
+
+1. Analyze the form (run analyze_form.py)
+2. Create field mapping (edit fields.json)
+3. Validate mapping (run validate_fields.py)
+4. Fill the form (run fill_form.py)
+5. Verify output (run verify_output.py)
+```
+
+## Conditional Workflows
+
+For tasks with branching logic, guide Claude through decision points:
+
+```markdown
+1. Determine the modification type:
+   **Creating new content?** → Follow "Creation workflow" below
+   **Editing existing content?** → Follow "Editing workflow" below
+
+2. Creation workflow: [steps]
+3. Editing workflow: [steps]
+```

+## Structuring This Skill
+
+[TODO: Choose the structure that best fits this skill's purpose. Common patterns:
+
+**1. Workflow-Based** (best for sequential processes)
+- Works well when there are clear step-by-step procedures
+- Example: DOCX skill with "Workflow Decision Tree" → "Reading" → "Creating" → "Editing"
+- Structure: ## Overview → ## Workflow Decision Tree → ## Step 1 → ## Step 2...
+
+**2. Task-Based** (best for tool collections)
+- Works well when the skill offers different operations/capabilities
+- Example: PDF skill with "Quick Start" → "Merge PDFs" → "Split PDFs" → "Extract Text"
+- Structure: ## Overview → ## Quick Start → ## Task Category 1 → ## Task Category 2...
+
+**3. Reference/Guidelines** (best for standards or specifications)
+- Works well for brand guidelines, coding standards, or requirements
+- Example: Brand styling with "Brand Guidelines" → "Colors" → "Typography" → "Features"
+- Structure: ## Overview → ## Guidelines → ## Specifications → ## Usage...
+
+**4. Capabilities-Based** (best for integrated systems)
+- Works well when the skill provides multiple interrelated features
+- Example: Product Management with "Core Capabilities" → numbered capability list
+- Structure: ## Overview → ## Core Capabilities → ### 1. Feature → ### 2. Feature...
+
+Patterns can be mixed and matched as needed. Most skills combine patterns (e.g., start with task-based, add workflow for complex operations).
+
+Delete this entire "Structuring This Skill" section when done - it's just guidance.]
+
+## [TODO: Replace with the first main section based on chosen structure]
+
+[TODO: Add content here. See examples in existing skills:
+- Code samples for technical skills
+- Decision trees for complex workflows
+- Concrete examples with realistic user requests
+- References to scripts/templates/references as needed]
+
+## Resources
+
+This skill includes example resource directories that demonstrate how to organize different types of bundled resources:
+
+### scripts/
+Executable code (Python/Bash/etc.) that can be run directly to perform specific operations.
+
+**Examples from other skills:**
+- PDF skill: `fill_fillable_fields.py`, `extract_form_field_info.py` - utilities for PDF manipulation
+- DOCX skill: `document.py`, `utilities.py` - Python modules for document processing
+
+**Appropriate for:** Python scripts, shell scripts, or any executable code that performs automation, data processing, or specific operations.
+
+**Note:** Scripts may be executed without loading into context, but can still be read by Claude for patching or environment adjustments.
+
+### references/
+Documentation and reference material intended to be loaded into context to inform Claude's process and thinking.
+
+**Examples from other skills:**
+- Product management: `communication.md`, `context_building.md` - detailed workflow guides
+- BigQuery: API reference documentation and query examples
+- Finance: Schema documentation, company policies
+
+**Appropriate for:** In-depth documentation, API references, database schemas, comprehensive guides, or any detailed information that Claude should reference while working.
+
+### assets/
+Files not intended to be loaded into context, but rather used within the output Claude produces.
+
+**Examples from other skills:**
+- Brand styling: PowerPoint template files (.pptx), logo files
+- Frontend builder: HTML/React boilerplate project directories
+- Typography: Font files (.ttf, .woff2)
+
+**Appropriate for:** Templates, boilerplate code, document templates, images, icons, fonts, or any files meant to be copied or used in the final output.
+
+---
+
+**Any unneeded directories can be deleted.** Not every skill requires all three types of resources.

+# Vercel React Best Practices
+
+Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
+
+## When to Apply
+
+Reference these guidelines when:
+- Writing new React components or Next.js pages
+- Implementing data fetching (client or server-side)
+- Reviewing code for performance issues
+- Refactoring existing React/Next.js code
+- Optimizing bundle size or load times
+
+## Rule Categories by Priority
+
+| Priority | Category | Impact | Prefix |
+|----------|----------|--------|--------|
+| 1 | Eliminating Waterfalls | CRITICAL | `async-` |
+| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |
+| 3 | Server-Side Performance | HIGH | `server-` |
+| 4 | Client-Side Data Fetching | MEDIUM-HIGH | `client-` |
+| 5 | Re-render Optimization | MEDIUM | `rerender-` |
+| 6 | Rendering Performance | MEDIUM | `rendering-` |
+| 7 | JavaScript Performance | LOW-MEDIUM | `js-` |
+| 8 | Advanced Patterns | LOW | `advanced-` |
+
+## Quick Reference
+
+### 1. Eliminating Waterfalls (CRITICAL)
+
+- `async-defer-await` - Move await into branches where actually used
+- `async-parallel` - Use Promise.all() for independent operations
+- `async-dependencies` - Use better-all for partial dependencies
+- `async-api-routes` - Start promises early, await late in API routes
+- `async-suspense-boundaries` - Use Suspense to stream content
+
+### 2. Bundle Size Optimization (CRITICAL)
+
+- `bundle-barrel-imports` - Import directly, avoid barrel files
+- `bundle-dynamic-imports` - Use next/dynamic for heavy components
+- `bundle-defer-third-party` - Load analytics/logging after hydration
+- `bundle-conditional` - Load modules only when feature is activated
+- `bundle-preload` - Preload on hover/focus for perceived speed
+
+### 3. Server-Side Performance (HIGH)
+
+- `server-cache-react` - Use React.cache() for per-request deduplication
+- `server-cache-lru` - Use LRU cache for cross-request caching
+- `server-serialization` - Minimize data passed to client components
+- `server-parallel-fetching` - Restructure components to parallelize fetches
+- `server-after-nonblocking` - Use after() for non-blocking operations
+
+### 4. Client-Side Data Fetching (MEDIUM-HIGH)
+
+- `client-swr-dedup` - Use SWR for automatic request deduplication
+- `client-event-listeners` - Deduplicate global event listeners
+
+### 5. Re-render Optimization (MEDIUM)
+
+- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
+- `rerender-memo` - Extract expensive work into memoized components
+- `rerender-dependencies` - Use primitive dependencies in effects
+- `rerender-derived-state` - Subscribe to derived booleans, not raw values
+- `rerender-functional-setstate` - Use functional setState for stable callbacks
+- `rerender-lazy-state-init` - Pass function to useState for expensive values
+- `rerender-transitions` - Use startTransition for non-urgent updates
+
+### 6. Rendering Performance (MEDIUM)
+
+- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
+- `rendering-content-visibility` - Use content-visibility for long lists
+- `rendering-hoist-jsx` - Extract static JSX outside components
+- `rendering-svg-precision` - Reduce SVG coordinate precision
+- `rendering-hydration-no-flicker` - Use inline script for client-only data
+- `rendering-activity` - Use Activity component for show/hide
+- `rendering-conditional-render` - Use ternary, not && for conditionals
+
+### 7. JavaScript Performance (LOW-MEDIUM)
+
+- `js-batch-dom-css` - Group CSS changes via classes or cssText
+- `js-index-maps` - Build Map for repeated lookups
+- `js-cache-property-access` - Cache object properties in loops
+- `js-cache-function-results` - Cache function results in module-level Map
+- `js-cache-storage` - Cache localStorage/sessionStorage reads
+- `js-combine-iterations` - Combine multiple filter/map into one loop
+- `js-length-check-first` - Check array length before expensive comparison
+- `js-early-exit` - Return early from functions
+- `js-hoist-regexp` - Hoist RegExp creation outside loops
+- `js-min-max-loop` - Use loop for min/max instead of sort
+- `js-set-map-lookups` - Use Set/Map for O(1) lookups
+- `js-tosorted-immutable` - Use toSorted() for immutability
+
+### 8. Advanced Patterns (LOW)
+
+- `advanced-event-handler-refs` - Store event handlers in refs
+- `advanced-use-latest` - useLatest for stable callback refs
+
+## How to Use
+
+Read individual rule files for detailed explanations and code examples:
+
+```
+rules/async-parallel.md
+rules/bundle-barrel-imports.md
+rules/_sections.md
+```
+
+Each rule file contains:
+- Brief explanation of why it matters
+- Incorrect code example with explanation
+- Correct code example with explanation
+- Additional context and references

+## Store Event Handlers in Refs
+
+Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
+
+**Incorrect (re-subscribes on every render):**
+
+```tsx
+function useWindowEvent(event: string, handler: (e) => void) {
+  useEffect(() => {
+    window.addEventListener(event, handler)
+    return () => window.removeEventListener(event, handler)
+  }, [event, handler])
+}
+```
+
+**Correct (stable subscription):**
+
+```tsx
+function useWindowEvent(event: string, handler: (e) => void) {
+  const handlerRef = useRef(handler)
+  useEffect(() => {
+    handlerRef.current = handler
+  }, [handler])
+
+  useEffect(() => {
+    const listener = (e) => handlerRef.current(e)
+    window.addEventListener(event, listener)
+    return () => window.removeEventListener(event, listener)
+  }, [event])
+}
+```
+
+**Alternative: use `useEffectEvent` if you're on latest React:**
+
+```tsx
+import { useEffectEvent } from 'react'
+
+function useWindowEvent(event: string, handler: (e) => void) {
+  const onEvent = useEffectEvent(handler)
+
+  useEffect(() => {
+    window.addEventListener(event, onEvent)
+    return () => window.removeEventListener(event, onEvent)
+  }, [event])
+}
+```
+
+`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

+
+## Prevent Waterfall Chains in API Routes
+
+In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
+
+**Incorrect (config waits for auth, data waits for both):**
+
+```typescript
+export async function GET(request: Request) {
+  const session = await auth()
+  const config = await fetchConfig()
+  const data = await fetchData(session.user.id)
+  return Response.json({ data, config })
+}
+```
+
+**Correct (auth and config start immediately):**
+
+```typescript
+export async function GET(request: Request) {
+  const sessionPromise = auth()
+  const configPromise = fetchConfig()
+  const session = await sessionPromise
+  const [config, data] = await Promise.all([
+    configPromise,
+    fetchData(session.user.id)
+  ])
+  return Response.json({ data, config })
+}
+```
+
+For operations with more complex dependency chains, use `better-all` to automatically maximize parallelism (see Dependency-Based Parallelization).

+---
+
+## Defer Await Until Needed
+
+Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
+
+**Incorrect (blocks both branches):**
+
+```typescript
+async function handleRequest(userId: string, skipProcessing: boolean) {
+  const userData = await fetchUserData(userId)
+  
+  if (skipProcessing) {
+    // Returns immediately but still waited for userData
+    return { skipped: true }
+  }
+  
+  // Only this branch uses userData
+  return processUserData(userData)
+}
+```
+
+**Correct (only blocks when needed):**
+
+```typescript
+async function handleRequest(userId: string, skipProcessing: boolean) {
+  if (skipProcessing) {
+    // Returns immediately without waiting
+    return { skipped: true }
+  }
+  
+  // Fetch only when needed
+  const userData = await fetchUserData(userId)
+  return processUserData(userData)
+}
+```
+
+**Another example (early return optimization):**
+
+```typescript
+// Incorrect: always fetches permissions
+async function updateResource(resourceId: string, userId: string) {
+  const permissions = await fetchPermissions(userId)
+  const resource = await getResource(resourceId)
+  
+  if (!resource) {
+    return { error: 'Not found' }
+  }
+  
+  if (!permissions.canEdit) {
+    return { error: 'Forbidden' }
+  }
+  
+  return await updateResourceData(resource, permissions)
+}
+
+// Correct: fetches only when needed
+async function updateResource(resourceId: string, userId: string) {
+  const resource = await getResource(resourceId)
+  
+  if (!resource) {
+    return { error: 'Not found' }
+  }
+  
+  const permissions = await fetchPermissions(userId)
+  
+  if (!permissions.canEdit) {
+    return { error: 'Forbidden' }
+  }
+  
+  return await updateResourceData(resource, permissions)
+}
+```
+
+This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

+
+## Strategic Suspense Boundaries
+
+Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
+
+**Incorrect (wrapper blocked by data fetching):**
+
+```tsx
+async function Page() {
+  const data = await fetchData() // Blocks entire page
+  
+  return (
+    <div>
+      <div>Sidebar</div>
+      <div>Header</div>
+      <div>
+        <DataDisplay data={data} />
+      </div>
+      <div>Footer</div>
+    </div>
+  )
+}
+```
+
+The entire layout waits for data even though only the middle section needs it.
+
+**Correct (wrapper shows immediately, data streams in):**
+
+```tsx
+function Page() {
+  return (
+    <div>
+      <div>Sidebar</div>
+      <div>Header</div>
+      <div>
+        <Suspense fallback={<Skeleton />}>
+          <DataDisplay />
+        </Suspense>
+      </div>
+      <div>Footer</div>
+    </div>
+  )
+}
+
+async function DataDisplay() {
+  const data = await fetchData() // Only blocks this component
+  return <div>{data.content}</div>
+}
+```
+
+Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
+
+**Alternative (share promise across components):**
+
+```tsx
+function Page() {
+  // Start fetch immediately, but don't await
+  const dataPromise = fetchData()
+  
+  return (
+    <div>
+      <div>Sidebar</div>
+      <div>Header</div>
+      <Suspense fallback={<Skeleton />}>
+        <DataDisplay dataPromise={dataPromise} />
+        <DataSummary dataPromise={dataPromise} />
+      </Suspense>
+      <div>Footer</div>
+    </div>
+  )
+}
+
+function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
+  const data = use(dataPromise) // Unwraps the promise
+  return <div>{data.content}</div>
+}
+
+function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
+  const data = use(dataPromise) // Reuses the same promise
+  return <div>{data.summary}</div>
+}
+```
+
+Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
+
+**When NOT to use this pattern:**
+
+- Critical data needed for layout decisions (affects positioning)
+- SEO-critical content above the fold
+- Small, fast queries where suspense overhead isn't worth it
+- When you want to avoid layout shift (loading → content jump)
+
+**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

+impact: CRITICAL

+tags: bundle, imports, tree-shaking, barrel-files, performance
+---
+
+## Avoid Barrel File Imports
+
+Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
+
+Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
+
+**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
+
+**Incorrect (imports entire library):**
+
+```tsx
+import { Check, X, Menu } from 'lucide-react'
+// Loads 1,583 modules, takes ~2.8s extra in dev
+// Runtime cost: 200-800ms on every cold start
+
+import { Button, TextField } from '@mui/material'
+// Loads 2,225 modules, takes ~4.2s extra in dev
+```
+
+**Correct (imports only what you need):**
+
+```tsx
+import Check from 'lucide-react/dist/esm/icons/check'
+import X from 'lucide-react/dist/esm/icons/x'
+import Menu from 'lucide-react/dist/esm/icons/menu'
+// Loads only 3 modules (~2KB vs ~1MB)
+
+import Button from '@mui/material/Button'
+import TextField from '@mui/material/TextField'
+// Loads only what you use
+```
+
+**Alternative (Next.js 13.5+):**
+
+```js
+// next.config.js - use optimizePackageImports
+module.exports = {
+  experimental: {
+    optimizePackageImports: ['lucide-react', '@mui/material']
+  }
+}
+
+// Then you can keep the ergonomic barrel imports:
+import { Check, X, Menu } from 'lucide-react'
+// Automatically transformed to direct imports at build time
+```
+
+Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
+
+Libraries commonly affected: `lucide-react`, `@mui/material`, `@mui/icons-material`, `@tabler/icons-react`, `react-icons`, `@headlessui/react`, `@radix-ui/react-*`, `lodash`, `ramda`, `date-fns`, `rxjs`, `react-use`.

+## Version and Minimize localStorage Data
+
+Add version prefix to keys and store only needed fields. Prevents schema conflicts and accidental storage of sensitive data.
+
+**Incorrect:**
+
+```typescript
+// No version, stores everything, no error handling
+localStorage.setItem('userConfig', JSON.stringify(fullUserObject))
+const data = localStorage.getItem('userConfig')
+```
+
+**Correct:**
+
+```typescript
+const VERSION = 'v2'
+
+function saveConfig(config: { theme: string; language: string }) {
+  try {
+    localStorage.setItem(`userConfig:${VERSION}`, JSON.stringify(config))
+  } catch {
+    // Throws in incognito/private browsing, quota exceeded, or disabled
+  }
+}
+
+function loadConfig() {
+  try {
+    const data = localStorage.getItem(`userConfig:${VERSION}`)
+    return data ? JSON.parse(data) : null
+  } catch {
+    return null
+  }
+}
+
+// Migration from v1 to v2
+function migrate() {
+  try {
+    const v1 = localStorage.getItem('userConfig:v1')
+    if (v1) {
+      const old = JSON.parse(v1)
+      saveConfig({ theme: old.darkMode ? 'dark' : 'light', language: old.lang })
+      localStorage.removeItem('userConfig:v1')
+    }
+  } catch {}
+}
+```
+
+**Store minimal fields from server responses:**
+
+```typescript
+// User object has 20+ fields, only store what UI needs
+function cachePrefs(user: FullUser) {
+  try {
+    localStorage.setItem('prefs:v1', JSON.stringify({
+      theme: user.preferences.theme,
+      notifications: user.preferences.notifications
+    }))
+  } catch {}
+}
+```
+
+**Always wrap in try-catch:** `getItem()` and `setItem()` throw in incognito/private browsing (Safari, Firefox), when quota exceeded, or when disabled.
+
+**Benefits:** Schema evolution via versioning, reduced storage size, prevents storing tokens/PII/internal flags.

+tags: javascript, dom, css, performance, reflow
+---
+
+## Batch DOM CSS Changes
+
+Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
+
+**Incorrect (interleaved reads and writes force reflows):**
+
+```typescript
+function updateElementStyles(element: HTMLElement) {
+  element.style.width = '100px'
+  const width = element.offsetWidth  // Forces reflow
+  element.style.height = '200px'
+  const height = element.offsetHeight  // Forces another reflow
+}
+```
+
+**Correct (batch writes, then read once):**
+
+```typescript
+function updateElementStyles(element: HTMLElement) {
+  // Batch all writes together
+  element.style.width = '100px'
+  element.style.height = '200px'
+  element.style.backgroundColor = 'blue'
+  element.style.border = '1px solid black'
+  
+  // Read after all writes are done (single reflow)
+  const { width, height } = element.getBoundingClientRect()
+}
+```
+
+**Better: use CSS classes**
+
+```css
+.highlighted-box {
+  width: 100px;
+  height: 200px;
+  background-color: blue;
+  border: 1px solid black;
+}
+```
+
+```typescript
+function updateElementStyles(element: HTMLElement) {
+  element.classList.add('highlighted-box')
+
+  const { width, height } = element.getBoundingClientRect()
+}
+```
+
+Prefer CSS classes over inline styles when possible. CSS files are cached by the browser, and classes provide better separation of concerns and are easier to maintain.

+## Cache Repeated Function Calls
+
+Use a module-level Map to cache function results when the same function is called repeatedly with the same inputs during render.
+
+**Incorrect (redundant computation):**
+
+```typescript
+function ProjectList({ projects }: { projects: Project[] }) {
+  return (
+    <div>
+      {projects.map(project => {

+        
+        return <ProjectCard key={project.id} slug={slug} />
+      })}
+    </div>
+  )
+}
+```
+
+**Correct (cached results):**
+
+```typescript
+// Module-level cache
+const slugifyCache = new Map<string, string>()
+
+function cachedSlugify(text: string): string {
+  if (slugifyCache.has(text)) {
+    return slugifyCache.get(text)!
+  }
+  const result = slugify(text)
+  slugifyCache.set(text, result)
+  return result
+}
+
+function ProjectList({ projects }: { projects: Project[] }) {
+  return (
+    <div>
+      {projects.map(project => {
+        // Computed only once per unique project name
+        const slug = cachedSlugify(project.name)
+        
+        return <ProjectCard key={project.id} slug={slug} />
+      })}
+    </div>
+  )
+}
+```
+
+**Simpler pattern for single-value functions:**
+
+```typescript
+let isLoggedInCache: boolean | null = null
+
+function isLoggedIn(): boolean {
+  if (isLoggedInCache !== null) {
+    return isLoggedInCache
+  }
+  
+  isLoggedInCache = document.cookie.includes('auth=')
+  return isLoggedInCache
+}
+
+// Clear cache when auth changes
+function onAuthChange() {
+  isLoggedInCache = null
+}
+```
+
+Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.

+
+## Early Length Check for Array Comparisons
+
+When comparing arrays with expensive operations (sorting, deep equality, serialization), check lengths first. If lengths differ, the arrays cannot be equal.
+
+In real-world applications, this optimization is especially valuable when the comparison runs in hot paths (event handlers, render loops).
+
+**Incorrect (always runs expensive comparison):**
+
+```typescript
+function hasChanges(current: string[], original: string[]) {
+  // Always sorts and joins, even when lengths differ
+  return current.sort().join() !== original.sort().join()
+}
+```
+
+Two O(n log n) sorts run even when `current.length` is 5 and `original.length` is 100. There is also overhead of joining the arrays and comparing the strings.
+
+**Correct (O(1) length check first):**
+
+```typescript
+function hasChanges(current: string[], original: string[]) {
+  // Early return if lengths differ
+  if (current.length !== original.length) {
+    return true
+  }
+  // Only sort when lengths match
+  const currentSorted = current.toSorted()
+  const originalSorted = original.toSorted()
+  for (let i = 0; i < currentSorted.length; i++) {
+    if (currentSorted[i] !== originalSorted[i]) {
+      return true
+    }
+  }
+  return false
+}
+```
+
+This new approach is more efficient because:
+- It avoids the overhead of sorting and joining the arrays when lengths differ
+- It avoids consuming memory for the joined strings (especially important for large arrays)
+- It avoids mutating the original arrays
+- It returns early when a difference is found

+  const sorted = [...projects].sort((a, b) => a.updatedAt - b.updatedAt)

+}
+```
+
+Still sorts unnecessarily when only min/max are needed.
+
+**Correct (O(n) - single loop):**
+
+```typescript
+function getLatestProject(projects: Project[]) {
+  if (projects.length === 0) return null
+  
+  let latest = projects[0]
+  
+  for (let i = 1; i < projects.length; i++) {

+    if (projects[i].updatedAt > newest.updatedAt) newest = projects[i]
+  }
+  
+  return { oldest, newest }
+}
+```
+
+Single pass through the array, no copying, no sorting.
+
+**Alternative (Math.min/Math.max for small arrays):**
+
+```typescript
+const numbers = [5, 2, 8, 1, 9]
+const min = Math.min(...numbers)
+const max = Math.max(...numbers)
+```
+
+This works for small arrays, but can be slower or just throw an error for very large arrays due to spread operator limitations. Maximal array length is approximately 124000 in Chrome 143 and 638000 in Safari 18; exact numbers may vary - see [the fiddle](https://jsfiddle.net/qw1jabsx/4/).

+tags: javascript, arrays, immutability, react, state, mutation

+
+## Use toSorted() Instead of sort() for Immutability
+
+`.sort()` mutates the array in place, which can cause bugs with React state and props. Use `.toSorted()` to create a new sorted array without mutation.
+
+**Incorrect (mutates original array):**
+
+```typescript
+function UserList({ users }: { users: User[] }) {
+  // Mutates the users prop array!
+  const sorted = useMemo(
+    () => users.sort((a, b) => a.name.localeCompare(b.name)),
+    [users]
+  )
+  return <div>{sorted.map(renderUser)}</div>
+}
+```
+
+**Correct (creates new array):**
+
+```typescript
+function UserList({ users }: { users: User[] }) {
+  // Creates new sorted array, original unchanged
+  const sorted = useMemo(
+    () => users.toSorted((a, b) => a.name.localeCompare(b.name)),
+    [users]
+  )
+  return <div>{sorted.map(renderUser)}</div>
+}
+```
+
+**Why this matters in React:**
+
+1. Props/state mutations break React's immutability model - React expects props and state to be treated as read-only
+2. Causes stale closure bugs - Mutating arrays inside closures (callbacks, effects) can lead to unexpected behavior
+
+**Browser support (fallback for older browsers):**
+
+`.toSorted()` is available in all modern browsers (Chrome 110+, Safari 16+, Firefox 115+, Node.js 20+). For older environments, use spread operator:
+
+```typescript
+// Fallback for older browsers
+const sorted = [...items].sort((a, b) => a.value - b.value)
+```
+
+**Other immutable array methods:**
+
+- `.toSorted()` - immutable sort
+- `.toReversed()` - immutable reverse
+- `.toSpliced()` - immutable splice
+- `.with()` - immutable element replacement

+## Animate SVG Wrapper Instead of SVG Element
+
+Many browsers don't have hardware acceleration for CSS3 animations on SVG elements. Wrap SVG in a `<div>` and animate the wrapper instead.
+
+**Incorrect (animating SVG directly - no hardware acceleration):**
+
+```tsx
+function LoadingSpinner() {

+  )
+}
+```
+
+**Correct (animating wrapper div - hardware accelerated):**
+
+```tsx
+function LoadingSpinner() {
+  return (
+    <div className="animate-spin">
+      <svg 
+        width="24"

+      </svg>
+    </div>
+  )
+}
+```
+
+This applies to all CSS transforms and transitions (`transform`, `opacity`, `translate`, `scale`, `rotate`). The wrapper div allows browsers to use GPU acceleration for smoother animations.

+
+## Prevent Hydration Mismatch Without Flickering
+
+When rendering content that depends on client-side storage (localStorage, cookies), avoid both SSR breakage and post-hydration flickering by injecting a synchronous script that updates the DOM before React hydrates.
+
+**Incorrect (breaks SSR):**
+
+```tsx
+function ThemeWrapper({ children }: { children: ReactNode }) {
+  // localStorage is not available on server - throws error
+  const theme = localStorage.getItem('theme') || 'light'
+  
+  return (
+    <div className={theme}>
+      {children}
+    </div>
+  )
+}
+```
+
+Server-side rendering will fail because `localStorage` is undefined.
+
+**Incorrect (visual flickering):**
+
+```tsx
+function ThemeWrapper({ children }: { children: ReactNode }) {
+  const [theme, setTheme] = useState('light')
+  
+  useEffect(() => {
+    // Runs after hydration - causes visible flash
+    const stored = localStorage.getItem('theme')
+    if (stored) {
+      setTheme(stored)
+    }
+  }, [])
+  
+  return (
+    <div className={theme}>
+      {children}
+    </div>
+  )
+}
+```
+
+Component first renders with default value (`light`), then updates after hydration, causing a visible flash of incorrect content.
+
+**Correct (no flicker, no hydration mismatch):**
+
+```tsx
+function ThemeWrapper({ children }: { children: ReactNode }) {
+  return (
+    <>
+      <div id="theme-wrapper">
+        {children}
+      </div>
+      <script
+        dangerouslySetInnerHTML={{
+          __html: `
+            (function() {
+              try {
+                var theme = localStorage.getItem('theme') || 'light';
+                var el = document.getElementById('theme-wrapper');
+                if (el) el.className = theme;
+              } catch (e) {}
+            })();
+          `,
+        }}
+      />
+    </>
+  )
+}
+```
+
+The inline script executes synchronously before showing the element, ensuring the DOM already has the correct value. No flickering, no hydration mismatch.
+
+This pattern is especially useful for theme toggles, user preferences, authentication states, and any client-only data that should render immediately without flashing default values.

+
+## Use Functional setState Updates
+
+When updating state based on the current state value, use the functional update form of setState instead of directly referencing the state variable. This prevents stale closures, eliminates unnecessary dependencies, and creates stable callback references.
+
+**Incorrect (requires state as dependency):**
+
+```tsx
+function TodoList() {
+  const [items, setItems] = useState(initialItems)
+  
+  // Callback must depend on items, recreated on every items change
+  const addItems = useCallback((newItems: Item[]) => {
+    setItems([...items, ...newItems])
+  }, [items])  // ❌ items dependency causes recreations
+  
+  // Risk of stale closure if dependency is forgotten
+  const removeItem = useCallback((id: string) => {
+    setItems(items.filter(item => item.id !== id))
+  }, [])  // ❌ Missing items dependency - will use stale items!
+  
+  return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
+}
+```
+
+The first callback is recreated every time `items` changes, which can cause child components to re-render unnecessarily. The second callback has a stale closure bug—it will always reference the initial `items` value.
+
+**Correct (stable callbacks, no stale closures):**
+
+```tsx
+function TodoList() {
+  const [items, setItems] = useState(initialItems)
+  
+  // Stable callback, never recreated
+  const addItems = useCallback((newItems: Item[]) => {
+    setItems(curr => [...curr, ...newItems])
+  }, [])  // ✅ No dependencies needed
+  
+  // Always uses latest state, no stale closure risk
+  const removeItem = useCallback((id: string) => {
+    setItems(curr => curr.filter(item => item.id !== id))
+  }, [])  // ✅ Safe and stable
+  
+  return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />
+}
+```
+
+**Benefits:**
+
+1. **Stable callback references** - Callbacks don't need to be recreated when state changes
+2. **No stale closures** - Always operates on the latest state value
+3. **Fewer dependencies** - Simplifies dependency arrays and reduces memory leaks
+4. **Prevents bugs** - Eliminates the most common source of React closure bugs
+
+**When to use functional updates:**
+
+- Any setState that depends on the current state value
+- Inside useCallback/useMemo when state is needed
+- Event handlers that reference state
+- Async operations that update state
+
+**When direct updates are fine:**
+
+- Setting state to a static value: `setCount(0)`
+- Setting state from props/arguments only: `setName(newName)`
+- State doesn't depend on previous value
+
+**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler can automatically optimize some cases, but functional updates are still recommended for correctness and to prevent stale closure bugs.

+
+## Cross-Request LRU Caching
+
+`React.cache()` only works within one request. For data shared across sequential requests (user clicks button A then button B), use an LRU cache.
+
+**Implementation:**
+
+```typescript
+import { LRUCache } from 'lru-cache'
+
+const cache = new LRUCache<string, any>({
+  max: 1000,
+  ttl: 5 * 60 * 1000  // 5 minutes
+})
+
+export async function getUser(id: string) {
+  const cached = cache.get(id)
+  if (cached) return cached
+
+  const user = await db.user.findUnique({ where: { id } })
+  cache.set(id, user)
+  return user
+}
+
+// Request 1: DB query, result cached
+// Request 2: cache hit, no DB query
+```
+
+Use when sequential user actions hit multiple endpoints needing the same data within seconds.
+
+**With Vercel's [Fluid Compute](https://vercel.com/docs/fluid-compute):** LRU caching is especially effective because multiple concurrent requests can share the same function instance and cache. This means the cache persists across requests without needing external storage like Redis.
+
+**In traditional serverless:** Each invocation runs in isolation, so consider Redis for cross-process caching.
+

+title: Per-Request Deduplication with React.cache()
+impact: MEDIUM
+impactDescription: deduplicates within request
+tags: server, cache, react-cache, deduplication
+---
+
+## Per-Request Deduplication with React.cache()
+
+Use `React.cache()` for server-side request deduplication. Authentication and database queries benefit most.
+
+**Usage:**
+
+```typescript
+import { cache } from 'react'
+
+export const getCurrentUser = cache(async () => {
+  const session = await auth()
+  if (!session?.user?.id) return null
+  return await db.user.findUnique({
+    where: { id: session.user.id }
+  })
+})
+```
+
+Within a single request, multiple calls to `getCurrentUser()` execute the query only once.
+
+**Avoid inline objects as arguments:**
+
+`React.cache()` uses shallow equality (`Object.is`) to determine cache hits. Inline objects create new references each call, preventing cache hits.
+
+**Incorrect (always cache miss):**
+
+```typescript
+const getUser = cache(async (params: { uid: number }) => {
+  return await db.user.findUnique({ where: { id: params.uid } })
+})
+
+// Each call creates new object, never hits cache
+getUser({ uid: 1 })
+getUser({ uid: 1 })  // Cache miss, runs query again
+```
+
+**Correct (cache hit):**
+
+```typescript
+const getUser = cache(async (uid: number) => {
+  return await db.user.findUnique({ where: { id: uid } })
+})
+
+// Primitive args use value equality
+getUser(1)
+getUser(1)  // Cache hit, returns cached result
+```
+
+If you must pass objects, pass the same reference:
+
+```typescript
+const params = { uid: 1 }
+getUser(params)  // Query runs
+getUser(params)  // Cache hit (same reference)
+```
+
+**Next.js-Specific Note:**
+
+In Next.js, the `fetch` API is automatically extended with request memoization. Requests with the same URL and options are automatically deduplicated within a single request, so you don't need `React.cache()` for `fetch` calls. However, `React.cache()` is still essential for other async tasks:
+
+- Database queries (Prisma, Drizzle, etc.)
+- Heavy computations
+- Authentication checks
+- File system operations
+- Any non-fetch async work
+
+Use `React.cache()` to deduplicate these operations across your component tree.
+

+```
+
+**Alternative with children prop:**
+
+```tsx
+async function Header() {
+  const data = await fetchHeader()
+  return <div>{data}</div>
+}
+
+async function Sidebar() {
+  const items = await fetchSidebarItems()
+  return <nav>{items.map(renderItem)}</nav>

+
+## Minimize Serialization at RSC Boundaries
+
+The React Server/Client boundary serializes all object properties into strings and embeds them in the HTML response and subsequent RSC requests. This serialized data directly impacts page weight and load time, so **size matters a lot**. Only pass fields that the client actually uses.
+
+**Incorrect (serializes all 50 fields):**
+
+```tsx
+async function Page() {
+  const user = await fetchUser()  // 50 fields
+  return <Profile user={user} />
+}
+
+'use client'
+function Profile({ user }: { user: User }) {
+  return <div>{user.name}</div>  // uses 1 field
+}
+```
+
+**Correct (serializes only 1 field):**
+
+```tsx
+async function Page() {
+  const user = await fetchUser()
+  return <Profile name={user.name} />
+}
+
+'use client'
+function Profile({ name }: { name: string }) {

+          prompt: |
+            You are a professional i18n synchronization engineer for the Dify project.
+            Your task is to keep all language translations in sync with the English source (en-US).
+
+            ## CRITICAL TOOL RESTRICTIONS
+            - Use **Read** tool to read files (NOT cat or bash)
+            - Use **Edit** tool to modify JSON files (NOT node, jq, or bash scripts)
+            - Use **Bash** ONLY for: git commands, gh commands, pnpm commands
+            - Run bash commands ONE BY ONE, never combine with && or ||
+            - NEVER use `$()` command substitution - it's not supported. Split into separate commands instead.
+
+            ## WORKING DIRECTORY & ABSOLUTE PATHS
+            Claude Code sandbox working directory may vary. Always use absolute paths:
+            - For pnpm: `pnpm --dir ${{ github.workspace }}/web <command>`
+            - For git: `git -C ${{ github.workspace }} <command>`
+            - For gh: `gh --repo ${{ github.repository }} <command>`
+            - For file paths: `${{ github.workspace }}/web/i18n/`
+
+            ## EFFICIENCY RULES
+            - **ONE Edit per language file** - batch all key additions into a single Edit
+            - Insert new keys at the beginning of JSON (after `{`), lint:fix will sort them
+            - Translate ALL keys for a language mentally first, then do ONE Edit
+
+            ## Context
+            - Changed/target files: ${{ steps.detect_changes.outputs.CHANGED_FILES }}
+            - Target languages (empty means all supported): ${{ steps.detect_changes.outputs.TARGET_LANGS }}
+            - Sync mode: ${{ steps.detect_changes.outputs.SYNC_MODE }}
+            - Translation files are located in: ${{ github.workspace }}/web/i18n/{locale}/{filename}.json
+            - Language configuration is in: ${{ github.workspace }}/web/i18n-config/languages.ts
+            - Git diff is available: ${{ steps.detect_changes.outputs.DIFF_AVAILABLE }}
+
+            ## CRITICAL DESIGN: Verify First, Then Sync
+
+            You MUST follow this three-phase approach:
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 1: VERIFY - Analyze and Generate Change Report       ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 1.1: Analyze Git Diff (for incremental mode)
+            Use the Read tool to read `/tmp/i18n-diff.txt` to see the git diff.
+
+            Parse the diff to categorize changes:
+            - Lines with `+` (not `+++`): Added or modified values
+            - Lines with `-` (not `---`): Removed or old values
+            - Identify specific keys for each category:
+              * ADD: Keys that appear only in `+` lines (new keys)
+              * UPDATE: Keys that appear in both `-` and `+` lines (value changed)
+              * DELETE: Keys that appear only in `-` lines (removed keys)
+
+            ### Step 1.2: Read Language Configuration
+            Use the Read tool to read `${{ github.workspace }}/web/i18n-config/languages.ts`.
+            Extract all languages with `supported: true`.
+
+            ### Step 1.3: Run i18n:check for Each Language
+            ```bash
+            pnpm --dir ${{ github.workspace }}/web install --frozen-lockfile
+            ```
+            ```bash
+            pnpm --dir ${{ github.workspace }}/web run i18n:check
+            ```
+
+            This will report:
+            - Missing keys (need to ADD)
+            - Extra keys (need to DELETE)
+
+            ### Step 1.4: Generate Change Report
+
+            Create a structured report identifying:
+            ```
+            ╔══════════════════════════════════════════════════════════════╗
+            ║                    I18N SYNC CHANGE REPORT                   ║

+            ║   - [filename].[key]: "English value"                        ║

+            ║ UPDATE (Modified Keys - MUST re-translate):                  ║
+            ║   - [filename].[key]: "Old value" → "New value"              ║
+            ║   ...                                                        ║
+            ╠══════════════════════════════════════════════════════════════╣
+            ║ DELETE (Extra Keys):                                         ║
+            ║   - [language]/[filename].[key]                              ║
+            ║   ...                                                        ║
+            ╚══════════════════════════════════════════════════════════════╝
+            ```
+
+            **IMPORTANT**: For UPDATE detection, compare git diff to find keys where
+            the English value changed. These MUST be re-translated even if target
+            language already has a translation (it's now stale!).
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 2: SYNC - Execute Changes Based on Report            ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 2.1: Process ADD Operations (BATCH per language file)
+
+            **CRITICAL WORKFLOW for efficiency:**
+            1. First, translate ALL new keys for ALL languages mentally
+            2. Then, for EACH language file, do ONE Edit operation:
+               - Read the file once
+               - Insert ALL new keys at the beginning (right after the opening `{`)
+               - Don't worry about alphabetical order - lint:fix will sort them later
+
+            Example Edit (adding 3 keys to zh-Hans/app.json):
+            ```
+            old_string: '{\n  "accessControl"'
+            new_string: '{\n  "newKey1": "translation1",\n  "newKey2": "translation2",\n  "newKey3": "translation3",\n  "accessControl"'
+            ```
+
+            **IMPORTANT**:
+            - ONE Edit per language file (not one Edit per key!)
+            - Always use the Edit tool. NEVER use bash scripts, node, or jq.
+
+            ### Step 2.2: Process UPDATE Operations
+
+            **IMPORTANT: Special handling for zh-Hans and ja-JP**
+            If zh-Hans or ja-JP files were ALSO modified in the same push:
+            - Run: `git -C ${{ github.workspace }} diff HEAD~1 --name-only` and check for zh-Hans or ja-JP files
+            - If found, it means someone manually translated them. Apply these rules:
+
+            1. **Missing keys**: Still ADD them (completeness required)
+            2. **Existing translations**: Compare with the NEW English value:
+               - If translation is **completely wrong** or **unrelated** → Update it
+               - If translation is **roughly correct** (captures the meaning) → Keep it, respect manual work
+               - When in doubt, **keep the manual translation**
+
+            Example:
+            - English changed: "Save" → "Save Changes"
+            - Manual translation: "保存更改" → Keep it (correct meaning)
+            - Manual translation: "删除" → Update it (completely wrong)
+
+            For other languages:
+            Use Edit tool to replace the old value with the new translation.
+            You can batch multiple updates in one Edit if they are adjacent.
+
+            ### Step 2.3: Process DELETE Operations
+            For extra keys reported by i18n:check:
+            - Run: `pnpm --dir ${{ github.workspace }}/web run i18n:check --auto-remove`
+            - Or manually remove from target language JSON files
+
+            ## Translation Guidelines
+
+            - PRESERVE all placeholders exactly as-is:
+              - `{{variable}}` - Mustache interpolation
+              - `${variable}` - Template literal
+              - `<tag>content</tag>` - HTML tags
+              - `_one`, `_other` - Pluralization suffixes (these are KEY suffixes, not values)
+            - Use appropriate language register (formal/informal) based on existing translations
+            - Match existing translation style in each language
+            - Technical terms: check existing conventions per language
+            - For CJK languages: no spaces between characters unless necessary
+            - For RTL languages (ar-TN, fa-IR): ensure proper text handling
+
+            ## Output Format Requirements
+            - Alphabetical key ordering (if original file uses it)
+            - 2-space indentation
+            - Trailing newline at end of file
+            - Valid JSON (use proper escaping for special characters)
+
+            ═══════════════════════════════════════════════════════════════
+            ║  PHASE 3: RE-VERIFY - Confirm All Issues Resolved           ║
+            ═══════════════════════════════════════════════════════════════
+
+            ### Step 3.1: Run Lint Fix (IMPORTANT!)
+            ```bash
+            pnpm --dir ${{ github.workspace }}/web lint:fix --quiet -- 'i18n/**/*.json'
+            ```
+            This ensures:
+            - JSON keys are sorted alphabetically (jsonc/sort-keys rule)
+            - Valid i18n keys (dify-i18n/valid-i18n-keys rule)
+            - No extra keys (dify-i18n/no-extra-keys rule)
+
+            ### Step 3.2: Run Final i18n Check
+            ```bash
+            pnpm --dir ${{ github.workspace }}/web run i18n:check
+            ```
+
+            ### Step 3.3: Fix Any Remaining Issues
+            If check reports issues:
+            - Go back to PHASE 2 for unresolved items
+            - Repeat until check passes
+
+            ### Step 3.4: Generate Final Summary
+            ```

+
+            ## Mode-Specific Behavior
+
+            **SYNC_MODE = "incremental"** (default):
+            - Focus on keys identified from git diff
+            - Also check i18n:check output for any missing/extra keys
+            - Efficient for small changes
+
+            **SYNC_MODE = "full"**:
+            - Compare ALL keys between en-US and each language
+            - Run i18n:check to identify all discrepancies
+            - Use for first-time sync or fixing historical issues
+
+            ## Important Notes
+
+            1. Always run i18n:check BEFORE and AFTER making changes
+            2. The check script is the source of truth for missing/extra keys
+            3. For UPDATE scenario: git diff is the source of truth for changed values
+            4. Create a single commit with all translation changes
+            5. If any translation fails, continue with others and report failures

+            git -C ${{ github.workspace }} status --porcelain
+            ```
+
+            If there are changes:
+
+            ### Step 4.2: Create a new branch and commit
+            Run these git commands ONE BY ONE (not combined with &&).
+            **IMPORTANT**: Do NOT use `$()` command substitution. Use two separate commands:
+
+            1. First, get the timestamp:
+            ```bash
+            date +%Y%m%d-%H%M%S
+            ```
+            (Note the output, e.g., "20260115-143052")
+
+            2. Then create branch using the timestamp value:
+            ```bash
+            git -C ${{ github.workspace }} checkout -b chore/i18n-sync-20260115-143052
+            ```
+            (Replace "20260115-143052" with the actual timestamp from step 1)
+
+            3. Stage changes:
+            ```bash
+            git -C ${{ github.workspace }} add web/i18n/
+            ```
+
+            4. Commit:
+            ```bash
+            git -C ${{ github.workspace }} commit -m "chore(i18n): sync translations with en-US - Mode: ${{ steps.detect_changes.outputs.SYNC_MODE }}"
+            ```
+
+            5. Push:
+            ```bash
+            git -C ${{ github.workspace }} push origin HEAD
+            ```
+
+            ### Step 4.3: Create Pull Request
+            ```bash
+            gh pr create --repo ${{ github.repository }} --title "chore(i18n): sync translations with en-US" --body "## Summary

+## Agent Notes (must-check)
+
+Before you start work on any backend file under `api/`, you MUST check whether a related note exists under:
+
+- `agent-notes/<same-relative-path-as-target-file>.md`
+
+Rules:
+
+- **Path mapping**: for a target file `<path>/<name>.py`, the note must be `agent-notes/<path>/<name>.py.md` (same folder structure, same filename, plus `.md`).
+- **Before working**:
+  - If the note exists, read it first and follow any constraints/decisions recorded there.
+  - If the note conflicts with the current code, or references an "origin" file/path that has been deleted, renamed, or migrated, treat the **code as the single source of truth** and update the note to match reality.
+  - If the note does not exist, create it with a short architecture/intent summary and any relevant invariants/edge cases.
+- **During working**:
+  - Keep the note in sync as you discover constraints, make decisions, or change approach.
+  - If you move/rename a file, migrate its note to the new mapped path (and fix any outdated references inside the note).
+  - Record non-obvious edge cases, trade-offs, and the test/verification plan as you go (not just at the end).
+  - Keep notes **coherent**: integrate new findings into the relevant sections and rewrite for clarity; avoid append-only “recent fix” / changelog-style additions unless the note is explicitly intended to be a changelog.
+- **When finishing work**:
+  - Update the related note(s) to reflect what changed, why, and any new edge cases/tests.
+  - If a file is deleted, remove or clearly deprecate the corresponding note so it cannot be mistaken as current guidance.
+  - Keep notes concise and accurate; they are meant to prevent repeated rediscovery.

-## Additional Notes for Agents
-
-- All skill docs assume you follow the coding style guide—run Ruff/BasedPyright/tests listed there before submitting changes.
+- All skill docs assume you follow the coding style rules below—run the lint/type/test commands before submitting changes.
 - When you cannot find an answer in these briefs, search the codebase using the paths referenced (e.g., `core/plugin/impl/tool.py`, `services/dataset_service.py`).
 - If you run into cross-cutting concerns (tenancy, configuration, storage), check the infrastructure guide first; it links to most supporting modules.
 - Keep multi-tenancy and configuration central: everything flows through `configs.dify_config` and `tenant_id`.
 - When touching plugins or triggers, consult both the system overview and the specialised doc to ensure you adjust lifecycle, storage, and observability consistently.
+
+## Coding Style
+
+This is the default standard for backend code in this repo. Follow it for new code and use it as the checklist when reviewing changes.
+
+### Linting & Formatting
+
+- Use Ruff for formatting and linting (follow `.ruff.toml`).
+- Keep each line under 120 characters (including spaces).
+
+### Naming Conventions
+
+- Use `snake_case` for variables and functions.
+- Use `PascalCase` for classes.
+- Use `UPPER_CASE` for constants.
+
+### Typing & Class Layout
+
+- Code should usually include type annotations that match the repo’s current Python version (avoid untyped public APIs and “mystery” values).
+- Prefer modern typing forms (e.g. `list[str]`, `dict[str, int]`) and avoid `Any` unless there’s a strong reason.
+- For classes, declare member variables at the top of the class body (before `__init__`) so the class shape is obvious at a glance:
+
+```python
+from datetime import datetime
+
+
+class Example:
+    user_id: str
+    created_at: datetime
+
+    def __init__(self, user_id: str, created_at: datetime) -> None:
+        self.user_id = user_id
+        self.created_at = created_at
+```
+
+### General Rules
+
+- Use Pydantic v2 conventions.
+- Use `uv` for Python package management in this repo (usually with `--project api`).
+- Prefer simple functions over small “utility classes” for lightweight helpers.
+- Avoid implementing dunder methods unless it’s clearly needed and matches existing patterns.
+- Never start long-running services as part of agent work (`uv run app.py`, `flask run`, etc.); running tests is allowed.
+- Keep files below ~800 lines; split when necessary.
+- Keep code readable and explicit—avoid clever hacks.
+
+### Architecture & Boundaries
+
+- Mirror the layered architecture: controller → service → core/domain.
+- Reuse existing helpers in `core/`, `services/`, and `libs/` before creating new abstractions.
+- Optimise for observability: deterministic control flow, clear logging, actionable errors.
+
+### Logging & Errors
+
+- Never use `print`; use a module-level logger:
+  - `logger = logging.getLogger(__name__)`
+- Include tenant/app/workflow identifiers in log context when relevant.
+- Raise domain-specific exceptions (`services/errors`, `core/errors`) and translate them into HTTP responses in controllers.
+- Log retryable events at `warning`, terminal failures at `error`.
+
+### SQLAlchemy Patterns
+
+- Models inherit from `models.base.TypeBase`; do not create ad-hoc metadata or engines.
+- Open sessions with context managers:
+
+```python
+from sqlalchemy.orm import Session
+
+with Session(db.engine, expire_on_commit=False) as session:
+    stmt = select(Workflow).where(
+        Workflow.id == workflow_id,
+        Workflow.tenant_id == tenant_id,
+    )
+    workflow = session.execute(stmt).scalar_one_or_none()
+```
+
+- Prefer SQLAlchemy expressions; avoid raw SQL unless necessary.
+- Always scope queries by `tenant_id` and protect write paths with safeguards (`FOR UPDATE`, row counts, etc.).
+- Introduce repository abstractions only for very large tables (e.g., workflow executions) or when alternative storage strategies are required.
+
+### Storage & External I/O
+
+- Access storage via `extensions.ext_storage.storage`.
+- Use `core.helper.ssrf_proxy` for outbound HTTP fetches.
+- Background tasks that touch storage must be idempotent, and should log relevant object identifiers.
+
+### Pydantic Usage
+
+- Define DTOs with Pydantic v2 models and forbid extras by default.
+- Use `@field_validator` / `@model_validator` for domain rules.
+
+Example:
+
+```python
+from pydantic import BaseModel, ConfigDict, HttpUrl, field_validator
+
+
+class TriggerConfig(BaseModel):
+    endpoint: HttpUrl
+    secret: str
+
+    model_config = ConfigDict(extra="forbid")
+
+    @field_validator("secret")
+    def ensure_secret_prefix(cls, value: str) -> str:
+        if not value.startswith("dify_"):
+            raise ValueError("secret must start with dify_")
+        return value
+```
+
+### Generics & Protocols
+
+- Use `typing.Protocol` to define behavioural contracts (e.g., cache interfaces).
+- Apply generics (`TypeVar`, `Generic`) for reusable utilities like caches or providers.
+- Validate dynamic inputs at runtime when generics cannot enforce safety alone.
+
+### Tooling & Checks
+
+Quick checks while iterating:
+
+- Format: `make format`
+- Lint (includes auto-fix): `make lint`
+- Type check: `make type-check`
+- Targeted tests: `make test TARGET_TESTS=./api/tests/<target_tests>`
+
+Before opening a PR / submitting:
+
+- `make lint`
+- `make type-check`
+- `make test`
+
+### Controllers & Services
+
+- Controllers: parse input via Pydantic, invoke services, return serialised responses; no business logic.
+- Services: coordinate repositories, providers, background tasks; keep side effects explicit.
+- Document non-obvious behaviour with concise comments.
+
+### Miscellaneous
+
+- Use `configs.dify_config` for configuration—never read environment variables directly.
+- Maintain tenant awareness end-to-end; `tenant_id` must flow through every layer touching shared resources.
+- Queue async work through `services/async_workflow_service`; implement tasks under `tasks/` with explicit queue selection.
+- Keep experimental scripts under `dev/`; do not ship them in production builds.

+## Purpose
+
+`api/controllers/console/datasets/datasets_document.py` contains the console (authenticated) APIs for managing dataset documents (list/create/update/delete, processing controls, estimates, etc.).
+
+## Storage model (uploaded files)
+
+- For local file uploads into a knowledge base, the binary is stored via `extensions.ext_storage.storage` under the key:
+  - `upload_files/<tenant_id>/<uuid>.<ext>`
+- File metadata is stored in the `upload_files` table (`UploadFile` model), keyed by `UploadFile.id`.
+- Dataset `Document` records reference the uploaded file via:
+  - `Document.data_source_info.upload_file_id`
+
+## Download endpoint
+
+- `GET /datasets/<dataset_id>/documents/<document_id>/download`
+
+  - Only supported when `Document.data_source_type == "upload_file"`.
+  - Performs dataset permission + tenant checks via `DocumentResource.get_document(...)`.
+  - Delegates `Document -> UploadFile` validation and signed URL generation to `DocumentService.get_document_download_url(...)`.
+  - Applies `cloud_edition_billing_rate_limit_check("knowledge")` to match other KB operations.
+  - Response body is **only**: `{ "url": "<signed-url>" }`.
+
+- `POST /datasets/<dataset_id>/documents/download-zip`
+
+  - Accepts `{ "document_ids": ["..."] }` (upload-file only).
+  - Returns `application/zip` as a single attachment download.
+  - Rationale: browsers often block multiple automatic downloads; a ZIP avoids that limitation.
+  - Applies `cloud_edition_billing_rate_limit_check("knowledge")`.
+  - Delegates dataset permission checks, document/upload-file validation, and download-name generation to
+    `DocumentService.prepare_document_batch_download_zip(...)` before streaming the ZIP.
+
+## Verification plan
+
+- Upload a document from a local file into a dataset.
+- Call the download endpoint and confirm it returns a signed URL.
+- Open the URL and confirm:
+  - Response headers force download (`Content-Disposition`), and
+  - Downloaded bytes match the uploaded file.
+- Select multiple uploaded-file documents and download as ZIP; confirm all selected files exist in the archive.
+
+## Shared helper
+
+- `DocumentService.get_document_download_url(document)` resolves the `UploadFile` and signs a download URL.
+- `DocumentService.prepare_document_batch_download_zip(...)` performs dataset permission checks, batches
+  document + upload file lookups, preserves request order, and generates the client-visible ZIP filename.
+- Internal helpers now live in `DocumentService` (`_get_upload_file_id_for_upload_file_document(...)`,
+  `_get_upload_file_for_upload_file_document(...)`, `_get_upload_files_by_document_id_for_zip_download(...)`).
+- ZIP packing is handled by `FileService.build_upload_files_zip_tempfile(...)`, which also:
+  - sanitizes entry names to avoid path traversal, and
+  - deduplicates names while preserving extensions (e.g., `doc.txt` → `doc (1).txt`).
+    Streaming the response and deferring cleanup is handled by the route via `send_file(path, ...)` + `ExitStack` +
+    `response.call_on_close(...)` (the file is deleted when the response is closed).

+## Purpose
+
+`api/services/dataset_service.py` hosts dataset/document service logic used by console and API controllers.
+
+## Batch document operations
+
+- Batch document workflows should avoid N+1 database queries by using set-based lookups.
+- Tenant checks must be enforced consistently across dataset/document operations.
+- `DocumentService.get_documents_by_ids(...)` fetches documents for a dataset using `id.in_(...)`.
+- `FileService.get_upload_files_by_ids(...)` performs tenant-scoped batch lookup for `UploadFile` (dedupes ids with `set(...)`).
+- `DocumentService.get_document_download_url(...)` and `prepare_document_batch_download_zip(...)` handle
+  dataset/document permission checks plus `Document -> UploadFile` validation for download endpoints.
+
+## Verification plan
+
+- Exercise document list and download endpoints that use the service helpers.
+- Confirm batch download uses constant query count for documents + upload files.
+- Request a ZIP with a missing document id and confirm a 404 is returned.

+## Purpose
+
+`api/services/file_service.py` owns business logic around `UploadFile` objects: upload validation, storage persistence,
+previews/generators, and deletion.
+
+## Key invariants
+
+- All storage I/O goes through `extensions.ext_storage.storage`.
+- Uploaded file keys follow: `upload_files/<tenant_id>/<uuid>.<ext>`.
+- Upload validation is enforced in `FileService.upload_file(...)` (blocked extensions, size limits, dataset-only types).
+
+## Batch lookup helpers
+
+- `FileService.get_upload_files_by_ids(tenant_id, upload_file_ids)` is the canonical tenant-scoped batch loader for
+  `UploadFile`.
+
+## Dataset document download helpers
+
+The dataset document download/ZIP endpoints now delegate “Document → UploadFile” validation and permission checks to
+`DocumentService` (`api/services/dataset_service.py`). `FileService` stays focused on generic `UploadFile` operations
+(uploading, previews, deletion), plus generic ZIP serving.
+
+### ZIP serving
+
+- `FileService.build_upload_files_zip_tempfile(...)` builds a ZIP from `UploadFile` objects and yields a seeked
+  tempfile **path** so callers can stream it (e.g., `send_file(path, ...)`) without hitting "read of closed file"
+  issues from file-handle lifecycle during streamed responses.
+- Flask `send_file(...)` and the `ExitStack`/`call_on_close(...)` cleanup pattern are handled in the route layer.
+
+## Verification plan
+
+- Unit: `api/tests/unit_tests/controllers/console/datasets/test_datasets_document_download.py`
+  - Verify signed URL generation for upload-file documents and ZIP download behavior for multiple documents.
+- Unit: `api/tests/unit_tests/services/test_file_service_zip_and_lookup.py`
+  - Verify ZIP packing produces a valid, openable archive and preserves file content.

+## Purpose
+
+Unit tests for the console dataset document download endpoint:
+
+- `GET /datasets/<dataset_id>/documents/<document_id>/download`
+
+## Testing approach
+
+- Uses `Flask.test_request_context()` and calls the `Resource.get(...)` method directly.
+- Monkeypatches console decorators (`login_required`, `setup_required`, rate limit) to no-ops to keep the test focused.
+- Mocks:
+  - `DatasetService.get_dataset` / `check_dataset_permission`
+  - `DocumentService.get_document` for single-file download tests
+  - `DocumentService.get_documents_by_ids` + `FileService.get_upload_files_by_ids` for ZIP download tests
+  - `FileService.get_upload_files_by_ids` for `UploadFile` lookups in single-file tests
+  - `services.dataset_service.file_helpers.get_signed_file_url` to return a deterministic URL
+- Document mocks include `id` fields so batch lookups can map documents by id.
+
+## Covered cases
+
+- Success returns `{ "url": "<signed>" }` for upload-file documents.
+- 404 when document is not `upload_file`.
+- 404 when `upload_file_id` is missing.
+- 404 when referenced `UploadFile` row does not exist.
+- 403 when document tenant does not match current tenant.
+- Batch ZIP download returns `application/zip` for upload-file documents.
+- Batch ZIP download rejects non-upload-file documents.
+- Batch ZIP download uses a random `.zip` attachment name (`download_name`), so tests only assert the suffix.

-## Linter
-
-- Always follow `.ruff.toml`.
-- Run `uv run ruff check --fix --unsafe-fixes`.

-
-## Code Style
-
-- `snake_case` for variables and functions.
-- `PascalCase` for classes.
-- `UPPER_CASE` for constants.
-
-## Rules
-
-- Use Pydantic v2 standard.
-- Use `uv` for package management.
-- Do not override dunder methods like `__init__`, `__iadd__`, etc.
-- Never launch services (`uv run app.py`, `flask run`, etc.); running tests under `tests/` is allowed.
-- Prefer simple functions over classes for lightweight helpers.
