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 | $0.00879 | $0.00879 |
| Opus 5.5 | $0.00352 | $0.00352 |
| Sonnet 5.5 | $0.00176 | $0.00176 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade A, and why
harus-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 29d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
harus-skills
Three Markdown skills shared across agent runtimes: revise for evidence-backed lessons, toolbelt for terminal tool choices, and playwright-verify for checking web apps in headless Chromium. Skill behavior lives in skills/<name>/SKILL.md; this file governs contributions to the repository.
Working principles
- Read the affected skill, its callers and the current repository state before editing. Current user and workspace instructions take precedence over recalled preferences and portable skill defaults.
- Keep each skill focused on its distinct job. Include guidance that changes a decision; remove repeated policy, cached inventories, and generic advice. Preserve useful recipes and concrete safety boundaries.
- Resolve routine uncertainty through repository evidence, installed CLI help, and safe checks. Continue authorized work; ask when the unresolved choice changes scope, authority, or the risk to user data.
- Reuse existing tools and targets. Define proportionate verification; distinguish structural validation from evidence that an agent follows the guidance correctly.
- Use independent subagents when useful and permitted by the current workspace. Worktrees and parallel sessions remain explicit opt-in.
- Preserve unrelated edits and partial staging. Use conventional commits without emojis, stage named files, and run
make checkbefore committing. Pushes, PRs, and other remote mutations require explicit authorization.
Skill ownership
| Skill | Source | Boundary |
|---|---|---|
revise |
skills/revise/SKILL.md |
Durable lessons with evidence; task status stays with Asobi |
toolbelt |
skills/toolbelt/SKILL.md |
Tool selection and recipes; project configuration owns the actual toolchain |
playwright-verify |
skills/playwright-verify/SKILL.md |
The browser-verification loop and the templates a project copies; each project owns its specs and make e2e |
Asobi's workflow guidance and CLI reference now live in the asobi repository. When using Asobi, follow that repository's guidance and consult asobi schema --command NAME for an exact command contract. Capture lessons when they would change future behavior; deduplicate and retain their evidence limits.
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.

harus-skills CLAUDE.md is an instructions file published in the GitHub repository azusachino/harus-skills (5 stars, last pushed 15d ago), licensed MIT. It adds 879 tokens to every session, about $0.0035 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.
