cursorrules AGENTS.md

cursorrules AGENTS.md is an instructions file for Codex, OpenCode from ivangrynenko/cursorrules. It costs 2,432 tokens per session, scanned A, original, MIT.

Project instructions for using a repository of Cursor rules with Cursor and coding agents. They explain installation choices, rule bundles, and how project-local AGENTS.md files are created.

In plain words
What is it for?
Use them to install selected or all rule sets, understand the available options, and configure Cursor for a project.
Why use it?
They give agents and developers a clear entry point instead of requiring them to discover the repository's rules and setup details themselves.

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 AGENTS.md 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 yesterday.

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.

Cursor Agents Guide (Using Cursor Rules)

This document explains how to use the rules in this repository with Cursor and serves as a single entry point that references the existing rule files. It avoids duplication by linking directly to the .cursor/rules/*.mdc sources.

If you installed these rules via the installer, a project‑local AGENTS.md can be generated that lists only the rules you chose. By default, the installer writes AGENTS.md if absent; it overwrites only when you pass --yes.

How To Use With Cursor

  • Open your project in Cursor. Rules under .cursor/rules are discovered automatically by Cursor.
  • Keep this AGENTS.md handy as your quick index to the rule set.
  • For installation methods and advanced options, see README.md.

Installation Options

For full installation details and examples, see README.md.

  • Core rules only: --core
  • Web stack (includes core): --web-stack or --ws
  • Python (includes core): --python
  • JavaScript security (includes core): --javascript
  • All rules: --all
  • Tag-based selection: --tags "<expression>" or --tag-preset <name>
  • Ignore files control: --ignore-files yes|no|ask

Tag taxonomy is documented in TAG_STANDARDS.md.

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.
