Cursor CLI Passthrough

Spawn Cursor's agent in a PTY background session and relay its output and the user's inputs as a silent passthrough.

Spawning

{ "tool": "exec", "command": "agent", "pty": true, "background": true, "workdir": "\x3Cproject-dir>", "yieldMs": 3000 }

• Always set workdir to the project directory the user wants to work in (not the OpenClaw workspace).
• If the user doesn't specify a directory, ask before spawning.
• Note: agent requires workspace trust on first run in a directory — relay the trust prompt and send the user's choice (e.g. a, w, or q) via process send-keys.

Relaying output

After spawning or sending input, poll for output:

{ "tool": "process", "action": "poll", "sessionId": "\x3Cid>", "timeout": 15000 }

• Strip ANSI escape codes mentally, but relay the content faithfully and verbatim.
• Do not wrap output in code blocks or quote formatting.
• Do not add preamble, postamble, interpretation, or commentary — relay exactly what Cursor outputs.
• If you need to add context or a note, prefix that line with your name in brackets (e.g. [YourName]) so it's clearly distinguished from Cursor's output.
• Permission prompts: When Cursor shows a "Run this command?" or any approval dialog, relay it verbatim to the user and wait for their response. Never approve or deny on the user's behalf.
• After relaying the agent's response, append a single prompt line: cursor @ \x3Cworkdir> — use ~ in place of the user's home directory (e.g. ~/repos/myproject not /home/username/repos/myproject).

Sending user input

For single-line prompts:

{ "tool": "process", "action": "submit", "sessionId": "\x3Cid>", "data": "\x3Ctext>" }

For multi-line prompts:

{ "tool": "process", "action": "paste", "sessionId": "\x3Cid>", "text": "\x3Ctext>" }

Then submit with Enter:

{ "tool": "process", "action": "send-keys", "sessionId": "\x3Cid>", "keys": ["Enter"] }

For other special keys (arrow keys, Escape, etc.):

{ "tool": "process", "action": "send-keys", "sessionId": "\x3Cid>", "keys": ["ArrowUp"] }

Use @filename or @directory/ in interactive prompts to add more context.

Ending the session

Send /quit or Ctrl+D (double-press):

{ "tool": "process", "action": "submit", "sessionId": "\x3Cid>", "data": "/quit" }

Notes

• agent is Cursor's CLI binary. cursor-agent is a backward-compatible alias.
• The binary must be on PATH. If not found, check TOOLS.md for custom binary paths.
• One session at a time is typical; use process list to check for orphaned sessions.
