Luong NGUYEN b9a973bf32 docs: accuracy pass against Claude Code v2.1.220 (#155)
Internal accuracy pass against v2.1.220 — no missing upstream features, but broken example code, disagreeing counts, and metadata drift.

Functional fixes: pre-commit.sh now exits 2 so it actually blocks; dependency-check.sh reads file_path from stdin JSON instead of $1; database-mcp.json uses ${DATABASE_URL}; broken fences repaired; three command templates had invalid skill names.

Factual corrections: /fork and /subtask unswapped and /subtask added; /fewer-permission-prompts; permissions.defaultMode; dontAsk/auto unreversed; 31 hook events verified name-by-name; subagent depth 3; skill precedence enterprise > project > personal; /output-style removed not deprecated; permissionDecision gained defer.

Follow-up review fixed defects the pass left behind: zh/vi headers claiming 31 events above 25-name lists, a surviving hardcoded DB credential in the MCP README examples, an unbalanced fence swallowing a metadata footer, and non-canonical tool names. All four translated CATALOG summary tables were recounted so their arithmetic holds.

Full detail in CHANGELOG.md under v2.1.220-r2.

# API Module Standards
This file supplements root CLAUDE.md for everything in /src/api/. Memory files are
concatenated, not overridden — the root CLAUDE.md still applies, and Claude Code
loads this file on demand when it reads files in this subtree.
## API-Specific Standards
### Request Validation
- Use Zod for schema validation
- Always validate input
- Return 400 with validation errors
- Include field-level error details
### Authentication
- All endpoints require JWT token
- Token in Authorization header
- Token expires after 24 hours
- Implement refresh token mechanism
### Response Format
All responses must follow this structure:
```json
{
"success": true,
"data": { /* actual data */ },
"timestamp": "2025-11-06T10:30:00Z",
"version": "1.0"
}
```
Error responses:
```json
{
"success": false,
"error": {
"code": "VALIDATION_ERROR",
"message": "User message",
"details": { /* field errors */ }
},
"timestamp": "2025-11-06T10:30:00Z"
}
```
### Pagination
- Use cursor-based pagination (not offset)
- Include `hasMore` boolean
- Limit max page size to 100
- Default page size: 20
### Rate Limiting
- 1000 requests per hour for authenticated users
- 100 requests per hour for public endpoints
- Return 429 when exceeded
- Include retry-after header
### Caching
- Use Redis for session caching
- Cache duration: 5 minutes default
- Invalidate on write operations
- Tag cache keys with resource type
