It enables AI agents to run background processes, send interactive input, and read output on demand. The plugin supports multiple concurrent PTY sessions with features like output buffering, regex filtering, and permission integration. +- **Functions/Variables**: camelCase (`setOnSessionUpdate`, `rawOutputCallbacks`) +- **Types/Classes**: PascalCase (`PTYManager`, `SessionLifecycleManager`) +- **Constants**: UPPER_CASE (`DEFAULT_READ_LIMIT`, `MAX_LINE_LENGTH`) +- **Directories**: kebab-case (`src/web/client`, `e2e`) +- **Files**: kebab-case for directories, camelCase for components/hooks (`useWebSocket.ts`, `TerminalRenderer.tsx`) -## Build/Lint/Test Commands +### TypeScript Configuration -### Type Checking -```bash -bun run typecheck -``` -Runs TypeScript compiler in no-emit mode to check for type errors. +- Strict TypeScript settings enabled (`strict: true`) +- Module resolution: `"bundler"` with `"moduleResolution": "bundler"` +- Target: ESNext with modern features +- No implicit returns or unused variables/parameters allowed +- Explicit type annotations required where beneficial -### Testing -```bash -bun test -``` -Runs all tests using Bun's test runner. +### Formatting (Prettier) -### Running a Single Test -```bash -bun test --match "test name pattern" -``` -Use the `--match` flag with a regex pattern to run specific tests. For example: -```bash -bun test --match "spawn" -``` +- **Semicolons**: Disabled (`semi: false`) +- **Quotes**: Single quotes preferred (`singleQuote: true`) +- **Trailing commas**: ES5 style (`trailingComma: "es5"`) +- **Print width**: 100 characters (`printWidth: 100`) +- **Indentation**: 2 spaces, no tabs (`tabWidth: 2`, `useTabs: false`) -### Linting -No dedicated linter configured. TypeScript strict mode serves as the primary code quality gate. +### Import/Export Style -## Code Style Guidelines +- Use ES6 imports/exports +- Group imports: external libraries first, then internal modules +- Prefer named exports over default exports for better tree-shaking +- Use absolute imports for internal modules where possible -### Language and Environment -- **Language**: TypeScript 5.x with ESNext target -- **Runtime**: Bun (supports TypeScript directly) -- **Module System**: ES modules with explicit `.ts` extensions in imports -- **JSX**: React JSX syntax (if needed, though this project is primarily backend) +### Documentation -### TypeScript Configuration -- Strict mode enabled (`strict: true`) -- Additional strict flags: `noFallthroughCasesInSwitch`, `noUncheckedIndexedAccess`, `noImplicitOverride` -- Module resolution: bundler mode -- Verbatim module syntax (no semicolons required) +- Use JSDoc comments for public APIs +- Inline comments for complex logic +- No redundant comments on self-explanatory code -### Imports and Dependencies -- Use relative imports with `.ts` extensions: `import { foo } from "../foo.ts"` -- Import types explicitly: `import type { Foo } from "./types.ts"` -- Group imports: external dependencies first, then internal -- Avoid wildcard imports (`import * as foo`) +--- -### Naming Conventions -- **Variables/Functions**: camelCase (`processData`, `spawnSession`) -- **Constants**: UPPER_CASE (`DEFAULT_LIMIT`, `MAX_LINE_LENGTH`) -- **Types/Interfaces**: PascalCase (`PTYSession`, `SpawnOptions`) -- **Classes**: PascalCase (`PTYManager`, `RingBuffer`) -- **Enums**: PascalCase (`PTYStatus`) -- **Files**: kebab-case for directories, camelCase for files (`spawn.ts`, `manager.ts`) - -### Code Structure -- **Functions**: Prefer arrow functions for tools, regular functions for utilities -- **Async/Await**: Use throughout for all async operations -- **Error Handling**: Throw descriptive Error objects, use try/catch for expected failures -- **Logging**: Use `createLogger` from `../logger.ts` for consistent logging -- **Tool Functions**: Use `tool()` wrapper with schema validation for all exported tools - -### Schema Validation -All tool functions must use schema validation: -```typescript -export const myTool = tool({ - description: "Brief description", - args: { - param: tool.schema.string().describe("Parameter description"), - optionalParam: tool.schema.boolean().optional().describe("Optional param"), - }, - async execute(args, ctx) { - // Implementation - }, -}); -``` +## Error Handling & Logging -### Error Messages -- Be descriptive and actionable -- Include context like session IDs or parameter values -- Suggest alternatives when possible (e.g., "Use pty_list to see active sessions") +### Error Handling Patterns -### File Organization -``` -src/ -├── plugin.ts # Main plugin entry point -├── types.ts # Plugin-level types -├── logger.ts # Logging

try/catch blocks for operations that may fail +- Throw descriptive `Error` objects with clear messages +- Handle errors gracefully in async operations +- Validate inputs and provide meaningful error messages +- Use custom error builders for common error types (e.g., `buildSessionNotFoundError`) -### Constants and Magic Numbers -- Define constants at the top of files: `const DEFAULT_LIMIT = 500;` -- Use meaningful names instead of magic numbers -- Group related constants together - -### Buffer Management -- Use RingBuffer for output storage (max 50,000 lines by default via `PTY_MAX_BUFFER_LINES`) -- Handle line truncation at 2000 characters -- Implement pagination with offset/limit for large outputs - -### Session Management -- Generate unique IDs using crypto: `pty_${hex}` -- Track session lifecycle: running → exited/killed -- Support cleanup on session deletion events -- Include parent session ID for proper isolation - -### Permission Integration -- Always check command permissions before spawning -- Validate working directory permissions -- Use wildcard matching for flexible permission rules - -### Testing -- Write tests for all public APIs -- Test error conditions and edge cases -- Use Bun's test framework -- Mock external dependencies when necessary +### Logging Approach -### Documentation -- Include `.txt` description files for each tool in `tools/` directory -- Use JSDoc sparingly, prefer `describe()` in schemas -- Keep README.md updated with usage examples - -### Security Considerations -- Never log sensitive information (passwords, tokens) -- Validate all user inputs, especially regex patterns -- Respect permission boundaries set by OpenCode -- Use secure random generation for session IDs - -### Performance -- Use efficient data structures (RingBuffer, Map for sessions) -- Avoid blocking operations in main thread -- Implement pagination for large outputs -- Clean up resources promptly - -### Commit Messages -Follow conventional commit format: -- `feat:` for new features -- `fix:` for bug fixes -- `refactor:` for code restructuring -- `test:` for test additions -- `docs:` for documentation changes - -### Git Workflow -- Use feature branches for development -- Run typecheck and tests before committing -- Use GitHub Actions for automated releases on main branch -- Follow semantic versioning with `v` prefixed tags - -### Dependencies -- **@opencode-ai/plugin**: ^1.1.3 (Core plugin framework) -- **@opencode-ai/sdk**: ^1.1.3 (SDK for client interactions) -- **bun-pty**: ^0.4.2 (PTY implementation) -- **@types/bun**: 1.3.1 (TypeScript definitions for Bun) -- **typescript**: ^5 (peer dependency) - -### Development Setup -- Install Bun: `curl -fsSL https://bun.sh/install | bash` -- Install
