opencode agent guidelines

Build/Test Commands

• Install: bun install
• Run: bun run 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: Go TUI communicates with TypeScript server via stainless SDK. When adding/modifying server endpoints in packages/opencode/src/server/server.ts, ask the user to generate a new client SDK to proceed with client-side changes.
