agent-skills: Instructions file for Codex

AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from quatico-solutions/agent-skills. It costs 1,933 tokens per session, scanned A, original, MIT.

A repository guidance file for coding agents working in the agent-skills project. It points agents to the main CLAUDE.md rules and highlights important requirements such as changeset-based versioning.

In plain words
What is it for?
Use it to guide agents when editing the repository, deciding where to find authoritative instructions, and completing changes that affect skills.
Why use it?
It prevents agents from following missing or outdated project rules, especially around version changes and required release steps.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is quatico-solutions/agent-skills's own configuration. It tells Codex and OpenCode how to work on agent-skills 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 agent-skills 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

agent-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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Agent instructions for the agent-skills repository: a single plugin, quatico-skills, over a flat pool of 19 skills in skills/. This file is the hub; the rules that need detail live in the docs/rules/ spokes listed under Where to Find More. CLAUDE.md imports this file with @AGENTS.md, so every agent reads the same rules.

Critical Rules

  1. NEVER edit version numbers by hand. The release pipeline owns metadata.version in every SKILL.md, version in .claude-plugin/plugin.json and .cursor-plugin/plugin.json, both marketplace.json files, and package.json. Hand-edits cause conflicts and drift.
  2. Every change that touches a skill MUST add a changeset. Run pnpm changeset and fill in the summary, the root bump, and the bumps: block. Indent tuned-against: by exactly two spaces, or CI fails — see docs/rules/versioning.md.
  3. Shell scripts MUST stay bash 3.2-compatible. macOS ships bash 3.2 and always will (bash 4 went GPLv3): no declare -A, no ${var^^}/${var,,}, no mapfile. Under set -u, expand possibly-empty arrays as ${arr[@]+"${arr[@]}"}. The bb-tests-macos CI job pins /bin/bash for cli/bb; every other script relies on this rule alone.
  4. NEVER use YAML block scalars in SKILL.md frontmatter. No >-, >, |-, | — Cursor does not parse them. description is a single-line "quoted string"; metadata.version is 3-part semver.
  5. Update README.md whenever skill membership changes. The skills table matches the contents of skills/, one row per skill, in alphabetical order by skill name. Add a new skill's row at its place in that order, not at the end. Nothing checks this.
  6. Prefer gates over rules. A rule is prose an agent can rationalise around; a gate is a hard stop with objective verification (a hook, a CI check). Every rule on this page is currently prose — see docs/rules/skill-development.md § Gates Over Rules.

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.
