agent-chorus: Cursor rule for Cursor

.cursorrules

cursorrules is a cursor rule for Cursor from cote-star/agent-chorus. It costs 74 tokens per session, scanned A, original, MIT.

A local command-line tool for reading, comparing, and handing off work between coding-agent sessions in Claude Code, Codex, Gemini, and Cursor. It uses checkpoints and messages to share context between agents.

In plain words
What is it for?
Use it to coordinate multi-agent coding sessions, pass work between agents, compare sessions, and keep repository searches within a defined scope.
Why use it?
It reduces repeated investigation when work moves between different coding agents. The included rules also limit searches to approved folders and require loading the task's context and completeness files first.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

This is cote-star/agent-chorus's own configuration. It tells Cursor how to work on agent-chorus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-chorus configures →

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.

Security

Grade A, and why

cursorrules scanned grade A with 0 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

  1. Read .agent-context/current/routes.json to identify task type
  2. Load contracts from .agent-context/current/completeness_contract.json + .agent-context/current/search_scope.json
  3. Search ONLY within scoped directories defined in search_scope.json
  4. Do not open repo source files before step 3

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.
