Autonomous AI coding agent - enhanced OpenCode with autonomous capabilities

# 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()`)

## IMPORTANT

- Try to keep things in one function unless composable or reusable
- DO NOT do unnecessary destructuring of variables
- DO NOT use `else` statements unless necessary
- DO NOT use `try`/`catch` if it can be avoided
- AVOID `try`/`catch` where possible
- AVOID `else` statements
- AVOID using `any` type
- AVOID `let` statements
- PREFER single word variable names where possible
- Use as many bun apis as possible like Bun.file()

## 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.
