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 | $0.00288 | $0.00288 |
| Opus 5.5 | $0.00115 | $0.00115 |
| Sonnet 5.5 | $0.00058 | $0.00058 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
skills CLAUDE.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
Skills — repo notes
Install deps with pnpm install; lint everything with pnpm lint
(skill lint + markdownlint over skills/**).
Layout: skills/<name>/SKILL.md are the installable units (English-only,
enforced by lint) — a flat directory, since the installer flattens names
anyway. Grouping is a README concern, not a filesystem one; group a skill
by adding it under the right ## section in README.md. Acceptance tests
and fixtures live in tests/.
Governance is per group, not repo-wide. The agent harness & skill
authoring group is spec-driven: changes to it go through openspec/
(/opsx:propose, /opsx:apply, /opsx:archive). Every other group is
lint-only — write the skill, pass pnpm lint, done. Do not open an
OpenSpec proposal for a skill outside the harness group.
Skills that depend on personal context (a specific employer, client, toolchain, or project layout) do not belong here — they live in a separate private repo. The test: does the skill need to know who I am?
Run the retro skill when a task ends; lessons land in .ai/learnings/, ideas in .ai/backlog/.
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.
