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 | $0.00185 | $0.00185 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade A, and why
agent-kit 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
Agent Kit repository instructions
This is a public repository. Treat every tracked byte as internet-visible.
- Never copy credentials, authentication state, transcripts, memories, private notes, or machine-local overrides into this repository.
- Use environment-variable names in examples; never include real values.
- Keep
catalog.jsonas the source of truth for accepted skills and upstream pins. - Treat
docs/top-skills.mdas a discovery radar, not an installation list. Add only a named skill that passes the full curation gate. - Preserve third-party license files and attribution.
- Do not overwrite an existing user skill directory. The installer must fail safely on conflicts.
- Run
python3 -m unittest discover -s tests -vand./bin/agent-kit doctor --strictafter changes. - Review executable vendor changes manually before accepting an upstream update.
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-kit AGENTS.md is an instructions file published in the GitHub repository cubxxw/agent-kit (2 stars, last pushed 27d ago), licensed MIT. It adds 185 tokens to every session, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
