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 | $0.01995 | $0.01995 |
| Opus 5.5 | $0.00798 | $0.00798 |
| Sonnet 5.5 | $0.00399 | $0.00399 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade A, and why
skill_steward 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 8d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Non-negotiables
- Original goal and native validation first — Steward governance exists to shorten future repair loops, not to delay the current fix.
- Structural stewardship only — no domain framework tutorial packs (React, Flutter, …); see North Star.
pnpm run validatebefore merging skill changes.- Claims need matching evidence — H2 smoke proof is not H4 fresh-agent proof; static evals are not runtime behavior. Use docs/core/evidence-ladder.mdx before claiming readiness.
- Plan hygiene — any planning tool is fine; when done, extract into ADR / FAQ / code / harness, then delete stale plan files (doctrine).
- AGENTS.md stays a map — skill authoring: docs/STANDARDS.mdx; do not bloat this file.
- Docs ≠ code — link to behavior SSOT; do not paraphrase implementations in prose.
- Ethical governance — all design decisions must be auditable against
charter-and-ethicsprinciples (Anti-Bloat, Reversibility, Legibility, Behavior-as-Truth, Artisan Restraint). - Anti-loops — two attempts then rewrite, delete, or hand off; one obligation per claimant; product use-path before fixtures; native

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.

skill_steward AGENTS.md is an instructions file published in the GitHub repository Arenukvern/skill_steward (11 stars, last pushed 8d ago), licensed MIT. It adds 1,995 tokens to every session, about $0.0080 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 2026-08-30.
