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 | $0.00449 | $0.00449 |
| Opus 5.5 | $0.00180 | $0.00180 |
| Sonnet 5.5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
open-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 yesterday.
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
Working on open-skills
These instructions apply to this repository. Read scope and CONTRIBUTING.md before changing skills or documentation.
- [open-skills.source] SKILL.md and its selected resources own skill behavior. Keep any protocol.yon aligned with that behavior; structural validity does not establish runtime obedience.
- [open-skills.scope] Make the smallest complete selected change. Preserve invocation policy, safeguards, dependencies and unrelated work; a recipe or conditional route can be enough without another skill.
- [open-skills.docs] Every public skill needs a source-grounded guide. Edit docs/skill-guides.json after reading its cited sources; tools/skill-docs.mjs defines the editorial model. Explain the reader's situation, mechanism, role, practical questions and recognizable result without inventing experience or behavior.
- [open-skills.generated] tools/spine.mjs owns catalogs, taxonomy projections, SKILLS.md, skills.sh.json and generated guides. tools/conformance.mjs owns CONFORMANCE.md. Do not hand-edit emitted files or refresh a source fingerprint without reconciling its guide.
- [open-skills.discovery] Add, rename or retire a skill together with its taxonomy assignment, guide disposition, README entry points and changelog. Counts and release versions move through their existing owners.
- [open-skills.installation] docs/installation.md owns shared installation/update wording. Keep source checks, installed bytes, runtime pickup and directory visibility as separate evidence claims. Existing links, editable copies and managed installs have different update owners.
- [open-skills.verification] Inspect command effects, then use proportionate checks for the actual candidate. Preserve recovery material outside public/discovery output and report failed or unrun checks. Do not turn optional examples or review into hidden dependencies.
- [open-skills.release] Follow the maintainer closeout in CONTRIBUTING.md. Record the exact intended scope and DCO identity before a commit. Editing does not itself authorize installation, deletion, Git publication or outreach.
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.
