OpenAI was rejecting tool definitions with error "schema must be a JSON Schema of 'type: "object"'". This was caused by AI SDK v5 not properly converting Zod schemas to JSON Schema format.
**Changes:**
- Upgrade AI SDK from v5.0.104 to v6.0.0-beta.124
- Upgrade @ai-sdk/openai from v2.0.74 to v3.0.0-beta.22
- Upgrade Zod from v3.25.76 to v4.1.13 across all packages
**AI SDK v6 breaking changes:**
- Tool definition API: `parameters` renamed to `inputSchema`
- Removed `aiTool()` wrapper - use plain object with description, inputSchema, execute
- Streaming API: Use `textStream` async iterator instead of onChunk callback
- Zod schemas now properly converted to JSON Schema for OpenAI
**Zod v4 breaking changes:**
- `z.record()` now requires two arguments: `z.record(keySchema, valueSchema)`
- `z.enum()` params changed: `errorMap` removed, use `message` instead
- Type system improvements require explicit type parameters
- Fixed type errors in @tpmjs/env, @tpmjs/npm-client, @tpmjs/types
**Files changed:**
- apps/web/src/lib/ai-agent/tool-executor-agent.ts
- Updated tool definition to use `inputSchema` instead of `parameters`
- Removed `aiTool()` wrapper
- Fixed streaming to use `textStream` iterator
- packages/env/src/index.ts
- Updated type constraint from `z.ZodRawShape` to `Record<string, z.ZodTypeAny>`
- packages/npm-client/src/package.ts
- Fixed `z.record()` calls to include both key and value schemas
- Added type assertions for record indexing
- packages/types/src/tpmjs.ts
- Changed `errorMap` to `message` in z.enum() calls
**Testing:**
- ✅ Type-check passes
- ✅ Production build succeeds
- ✅ All routes compile correctly
This fixes the tool execution error where OpenAI rejected tool schemas with invalid format.

**Database Schema:**
- Add npmReadme, npmKeywords, npmAuthor, npmMaintainers fields to Tool model
**NPM Client:**
- Add fetchLatestPackageWithMetadata() function to fetch README and top-level metadata
- Export new PackageVersionWithReadme type
**Sync Workers:**
- Update keyword and changes sync to fetch and store README content
- Store author, maintainers, and keywords from package.json
**UI Components:**
- Create Markdown component using react-markdown with GitHub Flavored Markdown
- Add rehype-sanitize for security and remark-gfm for tables/strikethrough support
**Tool Detail Page:**
- Convert from createElement to JSX for better maintainability
- Display README in a dedicated card with proper markdown rendering
- Show NPM keywords, author, and maintainers in sidebar
- Add ThemeToggle to header
- Improve layout with better spacing and organization
This brings the tool detail pages much closer to NPM's package pages,
providing users with comprehensive information about each tool including
the full README documentation.

Add complete sync worker system for NPM package discovery and metrics:
**Sync Workers:**
- Changes Feed Sync (/api/sync/changes) - Polls NPM changes every 2 min
- Keyword Search Sync (/api/sync/keyword) - Searches tpmjs-tool keyword every 15 min
- Metrics Sync (/api/sync/metrics) - Updates downloads & quality scores hourly
**Features:**
- Secure CRON_SECRET authentication for all sync endpoints
- Comprehensive error handling with sync logs and checkpoints
- Smart package validation and filtering (skip invalid tpmjs fields)
- Automatic tool upsert with discovery method tracking
- Quality score calculation based on tier, downloads, and GitHub stars
- 5-minute timeout support for long-running sync operations
**Dependencies:**
- Add @tpmjs/npm-client to web app for NPM API integration
- Use barrel exports from npm-client package (no subpath imports)
- Add CRON_SECRET env variable validation
- Add ~/src path alias to tsconfig
**Infrastructure:**
- Configure Vercel Cron jobs in vercel.json for automated syncing
- Add publishedAt field to PackageVersion schema
- Fix Prisma JSON field handling (use undefined instead of null)
- Proper null checks for fetchLatestPackageVersion return values
**Type Safety:**
- Cast TpmjsField union type to access optional rich-tier properties
- Handle searchByKeyword array return type correctly
- Fix fetchDownloadStats to return number directly
All API routes follow Next.js 16 conventions with proper type checking.
Type-check and full build successful.

- Implement changes feed client for real-time package discovery
- Implement keyword search with auto-pagination support
- Implement package metadata fetcher with tpmjs field extraction
- Implement download statistics client for quality scoring
- Implement rate limiter with configurable concurrency and delays
- Implement retry logic with exponential backoff for 429 errors
All API responses validated with Zod schemas for type safety.
Rate limiter defaults: max 10 concurrent, 100ms minimum delay.
Handles scoped packages (@scope/name) correctly.
Graceful 404 handling returns null instead of throwing.
