+## Build/Test Commands
+
+- **Install**: `bun install`
+- **Run**: `bun run --conditions=browser ./src/index.ts`
+- **Typecheck**: `bun run typecheck` (npm run typecheck)
+- **Test**: `bun test` (runs all tests)
+- **Single test**: `bun test test/tool/tool.test.ts` (specific test file)
+
+## Code Style
+
+- **Runtime**: Bun with TypeScript ESM modules
+- **Imports**: Use relative imports for local modules, named imports preferred
+- **Types**: Zod schemas for validation, TypeScript interfaces for structure
+- **Naming**: camelCase for variables/functions, PascalCase for classes/namespaces
+- **Error handling**: Use Result patterns, avoid throwing exceptions in tools
+- **File structure**: Namespace-based organization (e.g., `Tool.define()`, `Session.create()`)
+
+## Architecture
+
+- **Tools**: Implement `Tool.Info` interface with `execute()` method
+- **Context**: Pass `sessionID` in tool context, use `App.provide()` for DI
+- **Validation**: All inputs validated with Zod schemas
+- **Logging**: Use `Log.create({ service: "name" })` pattern
+- **Storage**: Use `Storage` namespace for persistence
+- **API Client**: The TypeScript TUI (built with SolidJS + OpenTUI) communicates with the OpenCode server using `@opencode-ai/sdk`. When adding/modifying server endpoints in `packages/opencode/src/server/server.ts`, run `./script/generate.ts` to regenerate the SDK and related files.
