+# TPMJS OpenCode Configuration
+
+This file contains project-specific rules and guidance for OpenCode agents working in the TPMJS monorepo.
+
+## Repository Overview
+
+TPMJS is a Turborepo monorepo for AI tool discovery and registry. Key characteristics:
+- **Package Manager**: pnpm with workspace configuration
+- **Build System**: Turborepo for task orchestration
+- **Main App**: Next.js 16 App Router (`apps/web`)
+- **Component Library**: `.ts`-only React components (`packages/ui`)
+- **Database**: Prisma with PostgreSQL (`packages/db`)
+- **Tool Registry**: npm package discovery and metadata sync
+
+## Core Commands (Always Use These)
+
+```bash
+# Development
+pnpm dev                    # Start all dev servers
+pnpm --filter=@tpmjs/web dev  # Start web app only
+
+# Building (Respects Dependencies)
+pnpm build                  # Build all packages
+pnpm --filter=@tpmjs/ui build  # Build specific package
+pnpm --filter=@tpmjs/web... build  # Build web + all dependencies
+
+# Testing & Quality
+pnpm test                   # Run all tests
+pnpm lint                   # Lint all packages
+pnpm format                 # Format with Biome
+pnpm type-check             # TypeScript checking
+```
+
+## Architecture Rules (Critical)
+
+### Module Boundaries
+- **Apps** (`apps/*`) can only import from published packages (`@tpmjs/*`)
+- **Packages** (`packages/*`) cannot import from apps
+- **UI Package** (`packages/ui`) cannot import from utils (stays dependency-free)
+- **No barrel exports** - always import directly: `@tpmjs/ui/Button/Button`
+
+### Component Usage
+**ALWAYS use `@tpmjs/ui` components instead of raw HTML:**
+```typescript
+// Good
+import { Button } from '@tpmjs/ui/Button/Button';
+import { Input } from '@tpmjs/ui/Input/Input';
+
+// Bad
+<button onClick={handleClick}>Submit</button>
+<input value={value} onChange={onChange} />
+```
+
+### TypeScript Configuration
+- All packages extend from `@tpmjs/tsconfig`
+- Strict mode enabled
+- Composite projects for proper dependency resolution
+
+## Package Structure
+
+### Published Packages (@tpmjs scope)
+- `@tpmjs/ui` - React component library (.ts-only, createElement)
+- `@tpmjs/utils` - Utility functions (cn, format, etc.)
+- `@tpmjs/types` - Shared TypeScript types and Zod schemas
+- `@tpmjs/env` - Environment variable validation with Zod
+
+### Internal Tooling (Private)
+- `@tpmjs/config` - Shared configurations (Biome, ESLint, Tailwind, TypeScript)
+- `@tpmjs/test` - Vitest shared configuration
+- `@tpmjs/mocks` - MSW mock server for testing
+- `@tpmjs/storybook` - Component documentation
+
+### Applications
+- `@tpmjs/web` - Next.js 16 App Router (main website)
+- `@tpmjs/playground` - Tool testing playground
+
+## Development Workflow
+
+### Before Making Changes
+1. Run `pnpm type-check` to ensure clean state
+2. Check existing patterns in similar files
+3. Use `@tpmjs/ui` components for any UI changes
+
+### After Making Changes
+1. `pnpm lint` - Check linting
+2. `pnpm type-check` - Verify TypeScript
+3. `pnpm test` - Run tests if applicable
+4. `pnpm format` - Auto-format with Biome
+
+### Database Changes
+If modifying Prisma schema:
+```bash
+pnpm --filter=@tpmjs/db db:generate  # Regenerate client
+pnpm --filter=@tpmjs/db db:push      # Apply changes (dev)
+```
+
+## Tool Development
+
+### Tool Package Structure
+Tools live in `packages/tools/*` with this pattern:
+```
+packages/tools/tool-name/
+├── package.json
+├── tsconfig.json
+├── src/
+│   ├── index.ts          # Main export
+│   ├── tool.ts           # Tool definition
+│   └── implementation.ts  # Actual logic
+├── README.md
+└── examples/
+    └── basic.ts
+```
+
+### Tool Metadata
+Tools must have proper `tpmjs` field in package.json:
+```json
+{
+  "tpmjs": {
+    "category": "text-analysis",
+    "tier": "rich",
+    "description": "Tool description"
+  }
+}
+```
+
+## Quality Standards
+
+### Code Quality
+- No `any` types or `@ts-ignore`
+- Strict TypeScript compliance
+- Proper error handling with try/catch
+- Meaningful variable names
+
+### Testing
+- Unit tests for utilities
+- Integration tests for API routes
+- Component tests for UI changes
+- Use Vitest + Testing Library
+
+### Documentation
+- README for all packages
+- JSDoc for public APIs
+- Examples for tool usage
+- Type definitions for all public interfaces
+
+## Common Patterns
+
+### API Routes
+```typescript
+import { NextResponse } from 'next/server';
+import { prisma } from '@tpmjs/db';
+
+export const runtime = 'nodejs';
+export const dynamic = 'force-dynamic';
+export const maxDuration = 60;
+
+export async function GET() {
+  try {
+    // Implementation
+    return NextResponse.json({ success: true, data });
+  } catch (error) {
+    return NextResponse.json(
+      { success: false, error: error.message },
+      { status: 500 }
+    );
+  }
+}
+```
+
+### Component Pattern
+```typescript
+import { createElement } from 'react';
+import { cn } from '@tpmjs/utils';
+
+interface ButtonProps {
+  onClick?: () => void;
+  children: React.ReactNode;
+  className?: string;
+}
+
+export function Button({ onClick, children, className }: ButtonProps) {
+  return createElement('button', {
+    onClick,
+    className: cn('default-styles', className),
+  }, children);
+}
+```
+
+## What NOT to Do
+
+- **Never edit lockfiles** unless explicitly requested
+- **Never use barrel exports** (`index.ts` files)
+- **Never suppress TypeScript errors** with `as any` or `@ts-ignore`
+- **Never use raw HTML elements** when `@tpmjs/ui` components exist
+- **Never import from apps** in packages
+- **Never commit without running** `pnpm lint` and `pnpm type-check`
+
+## Deployment & CI
+
+- Vercel deployment requires all CI checks to pass
+- Pre-commit hooks run `format`, `lint`, and `type-check`
+- Use `vercel inspect` to debug deployments
+- Check `/api/health` to verify production deployments
+
+## Getting Help
+
+- Check existing implementations in similar packages
+- Use `pnpm --filter=<package> dev` for package-specific development
+- Refer to `CLAUDE.md` for detailed architectural decisions
+- Look at `packages/tools/*` for tool development examples
