skills AGENTS.md

skills AGENTS.md is an instructions file for Codex, OpenCode from tomimor/skills. It costs 1,453 tokens per session, scanned A, original, MIT.

A contributor guide for a repository that stores reusable instructions for coding agents. It explains the repository layout, its own skills, and vendor skill sets supplied by other projects.

In plain words
What is it for?
Use it when adding a new skill, maintaining vendor links, checking the repository structure, or recreating the skill links used by Cursor and Claude Code.
Why use it?
It gives contributors the local rules needed to add or maintain skills without breaking how agents discover them. It also explains how the same skills are made available to different coding tools.

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

skills 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.

~/.cursor/skills is a symlink to skills/. ~/.claude/skills is a real directory whose entries are per-skill symlinks back into skills/ -- Claude Code does not load skills from a symlinked top-level directory, so the per-skill symlinks are how it picks them up while live edits in this repo still take effect. Any skill directory (or symlink) inside skills/ with a SKILL.md is automatically available to agents in both Cursor and Claude Code.

Re-create the per-skill symlinks if anything drifts:

./install.sh --symlink --all --force --target ~/.claude/skills

Adding a new own skill

Own skills are skills you write and maintain yourself. They live as regular directories under skills/.

  1. Create the directory and SKILL.md:
skills/<skill-name>/
├── SKILL.md              # Required
├── references/           # Optional -- detailed docs the agent reads on demand
│   └── some-reference.md
└── examples.md           # Optional
  1. SKILL.md must have YAML frontmatter with name and description:
---
name: my-skill-name
description: >-
  What this skill does and when to use it. Include trigger phrases
  so the agent knows when to activate it. Use when the user mentions
  X, Y, or Z.
---
  1. Register the skill in install.sh by adding an entry to the SKILLS array:
SKILLS=(
  ...existing entries...
  "my-skill-name:Short description for the install picker"
)

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.
