agent-resources AGENTS.md

Repository instructions for a collection of coding-agent skills and Cursor rules. They explain where these resources live and what files must be updated when adding a new one.

In plain words
What is it for?
Use them when creating, organizing, documenting, or registering skills and Cursor rule files.
Why use it?
They prevent incomplete additions by requiring new skills to have the right metadata and to be registered in the plugin manifest and project documentation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

agent-resources 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 3d 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

Agent Resources

This repository contains agent skills and Cursor rules.

Contributing

  • Skills live in skills/<category>/<skill-name>/SKILL.md.
  • Each SKILL.md has YAML frontmatter with name and description, followed by the skill body in markdown.
  • When adding a skill, also add it to .claude-plugin/plugin.json and the reference table in README.md.
  • Rules live in rules/ as .mdc files with YAML frontmatter (description, globs, alwaysApply).
  • Keep skills focused on a single concern. Prefer short, composable skills over large monolithic ones.
Changes

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.
