+## Build/Lint/Test Commands
+- **Build**: `pnpm run build` (TypeScript to dist/)
+- **Lint**: `pnpm run lint` (ESLint on src/**/*.ts)
+- **Type check**: `pnpm run type-check` (tsc --noEmit)
+- **Test**: `pnpm run test` (Vitest)
+- **Dev**: `pnpm run dev` (tsx watch src/server.ts)
+- **MCP Server**: `pnpm run mcp` or `pnpm run mcp:build`
+
+## Architecture
+- **GitHub Code Review Agent** using Hono.js framework
+- **Main components**: GitHub webhook processing, review queue, AI-powered code analysis
+- **Key directories**: src/github/ (auth, webhooks), src/review/ (queue, reviewer), src/mcp/ (Model Context Protocol)
+- **External integrations**: GitHub App API, Amp for AI reviews
+- **Configuration**: config.yml with environment variable interpolation
+
+## Code Style
+- **TypeScript ES2020 modules** with strict mode
+- **Imports**: Use .js extensions for local imports, group external first
+- **Error handling**: No explicit-any warnings, unused vars are errors
+- **Naming**: camelCase for variables/functions, PascalCase for types/classes
+- **Files**: kebab-case for filenames (review-queue.ts, webhook-manager.ts)
+- **Formatting**: ESLint config enforces prefer-const, no-var
