cursor-agent: Instructions file for Codex

AGENTS.md

cursor-agent AGENTS.md is an instructions file for Codex, OpenCode from toheart/cursor-agent. It costs 1,088 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for an AI coding agent, describing available skills and how to load them. It is intended for the Cursor agent and related tooling.

In plain words
What is it for?
Use it as configuration guidance when setting up an agent workspace, loading skills, or generating daily work summaries from Cursor conversations.
Why use it?
It gives the agent a consistent way to discover and use task-specific instructions instead of guessing how skills are organized.

Written for Codex and OpenCode: the file is AGENTS.md.

This is toheart/cursor-agent's own configuration. It tells Codex and OpenCode how to work on cursor-agent 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 cursor-agent 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

cursor-agent 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 2mo 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.

Available Skills

How to use skills:

  • Each skill has a tag containing the full path to the SKILL.md file
  • Read the skill file directly using: Read("")
  • The skill content will load with detailed instructions on how to complete the task
  • The parent directory of SKILL.md contains bundled resources (references/, scripts/, assets/)

Usage notes:

  • Only use skills listed in <available_skills> below
  • Do not invoke a skill that is already loaded in your context
  • Each skill invocation is stateless

Skills directory: C:\Users\Administrator.claude\skills

<available_skills>

</available_skills> daily-summary Generate daily work reports from Cursor chat history. Use when users request work summaries, daily reports, or need to review daily work content. Supports querying sessions by date, reading conversations, identifying work types, extracting tech debt, and saving summaries. Can optionally integrate git commit analysis.

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.
