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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00405 | $0.00405 |
| Opus 5 | $0.00202 | $0.00202 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00040 | $0.00040 |
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 2d 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
Repository guide for AI agents
This repo packages Agent Skills for Steadwing, an AI Root Cause Analysis platform. The skills let a coding agent self-register with Steadwing and trigger RCA on production errors.
Layout
skills/<name>/SKILL.md— the skill manifest and instructions (the entry point an agent reads).skills/<name>/references/— supporting docs loaded on demand.skills/<name>/scripts/— helper scripts (e.g. the error-detection hook and its installer).skills.sh.json— registry/grouping metadata for theskillsinstaller..claude-plugin/plugin.json— Claude Code plugin manifest (identity, version, license)..claude-plugin/marketplace.json— catalog for the self-hosted marketplace.hooks/hooks.json— registers the detection hook for plugin installs. Theinstall_hook.pyscript coversskills-CLI installs instead; keep the two in sync when the hook path changes.
Conventions
SKILL.mdfrontmatter requiresnameanddescription. Thedescriptionmust clearly state when to use the skill — it's how agents decide relevance.- Keep
SKILL.mdfocused; push detail intoreferences/. - Scripts must be dependency-free (Python 3 stdlib only) and cross-platform where feasible.
- The detection hook is passive: it surfaces errors and asks; it never calls the Steadwing API or sends data without explicit user confirmation.
Editing a skill
- Update
skills/<name>/SKILL.md(andreferences/as needed). - If you add a skill, list it in
skills.sh.jsonand the README table. - Validate JSON and SKILL frontmatter (CI runs
.github/workflows/validate.yml).
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.

agent-skills AGENTS.md is an instructions file published in the GitHub repository steadwing/agent-skills (2 stars, last pushed 20d ago), licensed MIT.
