Cursor CLI Skill

<identity> Headless wrapper for Cursor Agent CLI. Passes prompt as last positional arg to `cursor-agent --print --output-format text`. Multi-model routing via --model auto. Requires paid Cursor subscription. </identity> <capabilities> - Headless Cursor Agent CLI invocation with positional prompt - Multi-model routing (auto, claude-4.6-opus, gemini-3.1-pro, gpt-5.3-codex, etc.) - JSON output mode - YOLO mode (auto-approve all tool calls for non-interactive use) - Trust mode (skip workspace trust prompts) - MCP approval mode (--approve-mcps) - Wrapper-level timeout with exit code 124 - Complex Windows PATH resolution (agent, cursor-agent, %LOCALAPPDATA%, npx fallback) - Availability verification </capabilities>

Usage

Ask a question (auto model selection)

node .claude/skills/omega-cursor-cli/scripts/ask-cursor.mjs "How should I structure this React component?" --yolo --trust

Specific model

node .claude/skills/omega-cursor-cli/scripts/ask-cursor.mjs "Review this API design" --model claude-4.6-opus --yolo --trust

With timeout

node .claude/skills/omega-cursor-cli/scripts/ask-cursor.mjs "Refactor authentication" --yolo --trust --timeout-ms 180000

JSON output

node .claude/skills/omega-cursor-cli/scripts/ask-cursor.mjs "Generate types" --json --yolo --trust

Availability Check

node .claude/skills/omega-cursor-cli/scripts/verify-setup.mjs
# Exit 0 = available (CLI found)
# Exit 1 = not available

When to Use

• Multi-model perspective via Cursor's auto routing
• IDE-aware code generation (Cursor has workspace context)
• When a non-Claude, non-OpenAI perspective is desired
• Tasks where Cursor's composer models excel

Iron Laws

1. ALWAYS use --yolo --trust for headless mode (otherwise blocks on approval prompts)
2. NEVER assume CLI is available -- most restrictive subscription requirement
3. ALWAYS include --timeout-ms for production usage
4. NEVER attempt to detect subscription status programmatically (not possible)
5. ALWAYS handle WSL issues on Windows (some configurations require WSL)

Anti-Patterns

Anti-Pattern	Why Bad	Correct Approach
Running without --yolo	Blocks on tool approval prompts	Always pass --yolo
Running without --trust	Blocks on workspace trust prompt	Always pass --trust
Assuming auto model is available	Depends on subscription tier	Check with cursor-agent --list-models
Hardcoding cursor-agent path	PATH differs across OS/install methods	Wrapper handles resolution
Ignoring WSL requirements	Some Windows installs are WSL-only	Document in setup instructions

Scripts

Script	Purpose
ask-cursor.mjs	Core headless wrapper -- prompt as last positional arg
parse-args.mjs	Argument parser (--model, --json, --yolo, --trust, --timeout-ms)
verify-setup.mjs	Availability check (multi-path resolution)
format-output.mjs	Output normalization

Exit Codes

Code	Meaning
0	Success
1	Error (CLI failure, subscription issue)
124	Timeout (--timeout-ms exceeded)

Integration Notes

• Subscription: Cursor Pro or Business required for agent/headless mode
• Stdin limit: ASK_CURSOR_MAX_STDIN_BYTES env var (default 50MB)
• Available models: claude-4.6-opus, claude-4.6-sonnet, composer-1.5, gemini-3.1-pro, gpt-5.3-codex, auto
• Platform: Partial cross-platform (WSL issues on some Windows configurations)
• PATH resolution order: agent -> cursor-agent -> %LOCALAPPDATA%\cursor-agent\cursor-agent.cmd -> npx @cursor/agent
