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 | $0.00922 | $0.00922 |
| Opus 5 | $0.00461 | $0.00461 |
| Sonnet 5 | $0.00184 | $0.00184 |
| Haiku 4.5 | $0.00092 | $0.00092 |
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 7d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Instructions for coding agents working in the agent-skills repository.
CLAUDE.md is the source of truth. This file exists so agents that look for
AGENTS.mdby convention (Codex, Cursor, and others) find the repository's rules instead of nothing. It restates the rules that are easy to violate without noticing; everything else — repository structure, the full versioning flow, Plot configuration — lives in CLAUDE.md and is not duplicated here.A previous copy of this file was produced by a blind
Claude→Codexfind-and-replace, which invented a.Codex-plugin/directory and aCodex-opus-5model family, and dropped the bash 3.2 rule entirely. If you are tempted to regenerate this file mechanically: don't. Where the two files disagree, CLAUDE.md wins.
Rules that bite
1. Never edit version numbers by hand. Versioning is changeset-driven. Do
not touch metadata.version in any SKILL.md, version in
.claude-plugin/plugin.json or .cursor-plugin/plugin.json, the
marketplace.json files, or package.json. The release pipeline owns all of
them.
2. Every change touching a skill needs a changeset. pnpm changeset, then
edit the created file: a one-line summary, a root-package bump, and a bumps:
block listing each changed skill. Record tuned-against: claude-opus-5 (the
model family, never a dated snapshot) when a change is model-specific. CI only
warns when a changeset is missing — it will not catch this for you.
3. Shell scripts must stay bash 3.2-compatible. macOS ships bash 3.2 and
always will (bash 4 went GPLv3): no declare -A, no ${var^^}/${var,,}, no
mapfile. Under set -u, expand possibly-empty arrays as
${arr[@]+"${arr[@]}"}. Gated for bin/bb by the bb-tests-macos CI job,
which pins /bin/bash; every other script relies on this rule alone.
4. Never use YAML block scalars in SKILL.md frontmatter. No >-, >, |-,
| — Cursor does not parse them. description is a single-line quoted string;
metadata.version is 3-part semver.
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 quatico-solutions/agent-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 922 tokens to every session, about $0.0046 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.
