agent-skills: Instructions file for Codex

AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from openclaw/agent-skills. It costs 218 tokens per session, scanned A, original, MIT.

A set of repository instructions for organising shared skills used by coding agents. It defines where skill files and helper scripts belong and how to keep shared examples safe to publish.

In plain words
What is it for?
Use it when adding or maintaining public agent skills, their documentation, or helper scripts. It helps keep the repository layout and publishing workflow consistent.
Why use it?
It prevents shared skills from becoming inconsistent, exposing private information, or being edited in generated copies. It also gives agents a validation step after changes.

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

This is openclaw/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 1mo 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

AGENTS.md

Public shared skills for agent workflows.

Rules

  • Canonical shared skills live under skills/<name>/SKILL.md.
  • Keep repo-specific workflows out unless they are useful as public examples.
  • Keep secrets, private hostnames, private account IDs, and private URLs out.
  • Skill descriptions: short trigger phrase, not full documentation.
  • Skill bodies: operational, terse, current.
  • Helper scripts belong under skills/<name>/scripts/.
  • Validate after edits: scripts/validate-skills.
  • Do not edit generated/vendor copies in downstream repos; update here, then sync.
  • Autoreview consumers use one shared installation and a Markdown entrypoint. Do not restore vendored autoreview implementations or tests.

Layout

  • skills/autoreview: shared closeout/code-review helper.
  • skills/beam: redacted read-only coding-session publication.
  • skills/crabbox: shared Crabbox/Testbox remote validation workflow.
  • skills/team-handoff: one-request worktree session handoff to a shared Gateway.
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.
