+# OpenCode Context
+
+## Build/Test Commands
+
+- `bun install` - Install dependencies
+- `bun run index.ts` - Run the application
+- `bun build src/index.ts --compile --outfile ./dist/opencode` - Build executable
+- `bun test` - Run all tests
+- `bun test <pattern>` - Run specific test files
+- `bun test --test-name-pattern <regex>` - Run tests matching pattern
+
+## Code Style & Conventions
+
+- TypeScript with Bun runtime
+- ES modules (`"type": "module"`)
+- Namespace-based organization (e.g., `Tool.define`, `App.provide`)
+- Zod for schema validation and type safety
+- Async/await patterns throughout
+- Structured logging with service-based loggers (`Log.create({ service: "name" })`)
+- Tool pattern: define tools with `Tool.define()` wrapper for metadata/timing
+- Context pattern: use `Context.create()` for dependency injection
+- Import style: Node.js built-ins with `node:` prefix, relative imports with explicit extensions
+- Error handling: try/catch with structured logging
+- File organization: group by feature in `src/` with index files for exports
+- Test files: co-located in `test/` directory, use Bun's built-in test runner
+- Naming: camelCase for variables/functions, PascalCase for namespaces/types
+- **Variable declarations: Prefer `const` over `let` unless reassignment is necessary**
