Files created: - src/cursor/cursor-daemon.ts (~230 LOC) - Lifecycle management (start/stop/status) - src/cursor/cursor-models.ts (~145 LOC) - Model catalog with Anthropic/OpenAI/Google/Cursor models - src/cursor/index.ts (~30 LOC) - Module barrel exports - src/commands/cursor-command.ts (~230 LOC) - CLI commands (auth/status/models/start/stop) Key features: - Daemon health checks via HTTP /health endpoint - PID file management in ~/.ccs/cursor/daemon.pid - Model catalog with fetchModelsFromDaemon() and fallback defaults - CLI subcommand routing following copilot-command.ts pattern - ASCII-only output ([OK], [X], [i] markers) Temporary defaults for config (port: 4242, model: gpt-4.1) until #521 adds cursor to unified config schema. Note: Actual daemon server implementation (CursorExecutor integration) deferred to #522 - this creates the lifecycle structure only. --- src/commands/cursor-command.ts | 238 +++++++++++++++++++++++++++++++ src/cursor/cursor-daemon.ts | 253 +++++++++++++++++++++++++++++++++ src/cursor/cursor-models.ts | 166 +++++++++++++++++++++ src/cursor/index.ts | 30 ++++ 4 files changed, 687 insertions(+) create mode 100644 src/commands/cursor-command.ts create mode 100644 src/cursor/cursor-daemon.ts create mode 100644 src/cursor/cursor-models.ts create mode 100644 src/cursor/index.ts diff --git a/src/commands/cursor-command.ts b/src/commands/cursor-command.ts new file mode 100644 index 00000000..ecbb6602 --- /dev/null +++ b/src/commands/cursor-command.ts @@ -0,0 +1,238 @@ +/** + * Cursor CLI Command + * + * Handles `ccs cursor ` commands. + */ + +import { + autoDetectTokens, + checkAuthStatus, + startDaemon, + stopDaemon, + getDaemonStatus, + getAvailableModels, +} from '../cursor'; +import { ok, fail, info, color } from '../utils/ui'; + +// Temporary default config until #521 adds cursor to unified config +const DEFAULT_CURSOR_CONFIG = { + port: 4242, + model: 'gpt-4.1', +}; + +/** + * Handle cursor subcommand. + */ +export async function handleCursorCommand(args: string[]): Promise { + const subcommand = args[0]; + + switch (subcommand) { + case 'auth': + return handleAuth(); + case 'status': + return handleStatus(); + case 'models': + return handleModels(); + case 'start': + return handleStart(); + case 'stop': + return handleStop(); + case undefined: + case 'help': + case '--help': + case '-h': + return handleHelp(); + default: + console.error(fail(`Unknown subcommand: ${subcommand}`)); + console.error(''); + return handleHelp(); + } +} + +/** + * Show help for cursor commands. + */ +function handleHelp(): number { + console.log('Cursor IDE Integration'); + console.log(''); + console.log('Usage: ccs cursor '); + console.log(''); + console.log('Subcommands:'); + console.log(' auth Import Cursor IDE authentication token'); + console.log(' status Show authentication and daemon status'); + console.log(' models List available models'); + console.log(' start Start cursor daemon'); + console.log(' stop Stop cursor daemon'); + console.log(' help Show this help message'); + console.log(''); + console.log('Quick start:'); + console.log(' 1. ccs cursor auth # Import Cursor IDE token'); + console.log(' 2. ccs cursor start # Start daemon'); + console.log(' 3.
