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 5.1 | $0.00150 | $0.00150 |
| Opus 5.5 | $0.00060 | $0.00060 |
| Sonnet 5.5 | $0.00030 | $0.00030 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade A, and why
engineering-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 2mo 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
Engineering Agent Skills Contributor Guide
Repository Boundaries
- Canonical portable skills live under
skills/and must remain independently installable. - Always-on collaboration policies live under
policies/; do not package them as conditionally loaded skills. - Vendor adapters may map canonical content to native formats, but must not maintain a second copy of that content.
- Generated packages belong under
dist/and must not be committed.
Changes
- Keep instructions concise and grounded in observable agent behavior.
- Preserve portability. Put vendor-specific paths and metadata in installers or adapters, not canonical skills or policies.
- Update validation when adding a new canonical artifact or installation behavior.
- Run
./scripts/validate.shbefore submitting 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.

engineering-agent-skills AGENTS.md is an instructions file published in the GitHub repository fikrilal/engineering-agent-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 150 tokens to every session, about $0.0006 per session on Opus 5.5. 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.
