A command that checks whether the Cursor command-line tool is installed and authenticated, and can optionally install it.

Use it to verify or install Cursor CLI and to surface authentication instructions when an API key or interactive login is needed.

It identifies setup problems before you try to delegate coding work to Cursor.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.00222
Opus 5.5	$0.00005	$0.00089
Sonnet 5.5	$0.00003	$0.00044
Haiku 4.5	$0.00001	$0.00022

Security

Grade C, and why

setup scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/cursor-companion.mjs" setup --json

If cursor-agent is missing:

Use AskUserQuestion exactly once to ask whether Claude should install Cursor CLI now.
Put the install option first and suffix it with (Recommended).
Use these two options:
- Install Cursor CLI (Recommended)
- Skip for now
If the user chooses install, run:

curl https://cursor.com/install -fsS | bash

Then rerun:

node "${CLAUDE_PLUGIN_ROOT}/scripts/cursor-companion.mjs" setup --json

If Cursor is installed but not authenticated, surface the guidance to set CURSOR_API_KEY in the environment or run !cursor-agent interactively to log in. Do not auto-execute login.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
