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

repo 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 9d 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

Cursor Repository Rules

This file was generated by repo2agent. It gives AI coding agents the shortest reliable path to work safely in this repository.

Repository Snapshot

  • Name: repo2agent
  • Stack: Not detected
  • Package manager: npm

Project Map

  • lib/
  • test/
  • docs/
  • examples/
  • .npm-cache/
  • bin/

Common Commands

  • test: npm run test
  • lint: npm run lint

Agent Workflow

  • Read the relevant files before editing.
  • Prefer existing patterns, naming, and architecture over new abstractions.
  • Keep changes scoped to the user request.
  • Do not rewrite unrelated code or reformat files outside the change.
  • Do not discard local/user changes without explicit permission.
  • Update tests when behavior changes.
  • Run the smallest meaningful verification command before finalizing.
  • In the final response, say what changed, what was verified, and what risk remains.

Safety Rules

  • Be careful with secrets, auth, permissions, payments, migrations, generated files, and lockfiles.
  • Avoid adding dependencies unless they clearly reduce complexity.
  • If a command fails, report the failure and choose the next most useful verification step.

Cursor Notes

  • Apply these rules to code edits, reviews, refactors, and generated tests.

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.
