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 | $0.00821 | $0.00821 |
| Opus 5 | $0.00411 | $0.00411 |
| Sonnet 5 | $0.00164 | $0.00164 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
claude-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 10d 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 — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claude-skills
Personal Agent Skills library, published as the shaharsha-skills marketplace. Each skill is a folder under skills/<name>/ with a SKILL.md. Skills are consumed by Claude Code, Codex, Cursor, and other Agent-Skills harnesses — keep them harness-agnostic (no assumptions about a specific host's tools).
Edit skills here, in this repo. Each is symlinked into ~/.claude/skills/<name>, so that path is this repo — don't expect a separate editable copy under ~/.claude/skills.
Adding or renaming a skill — update ALL of these
Miss one and the skill ships half-wired (installs but isn't listed, or is listed but 404s):
skills/<name>/SKILL.md— frontmattername+description. The description is when to trigger (third-person "Use when…", keyword-rich); it's the only thing that makes the skill fire, so it is not a workflow summary.skills/<name>/README.md— the GitHub landing page for that folder. SKILL.md is for the model; README.md is for the human — it links into SKILL.md andreference/rather than restating procedure. Sections: pitch, why it exists, what it does, install (marketplace + monorepo path), requirements, quick start, gotchas, related skills, license. Copy the shape from any existing one..claude-plugin/marketplace.json— add./skills/<name>to the mainshaharsha-skillsplugin (and update its "All N skills" count in that plugin's description) and to the fitting category plugin; bumpmetadata.version.README.md— the matching/plugin install <category>@shaharsha-skillscomment line, plus a one-line row in that category's table. One sentence, not a paragraph — the long description lives in the skill's own README.~/Projects/shahar-sh/public/skills.html— separate repo. Add a skill card, append the name to the<meta name="description">list, and bump the two "N skills" counts. Pushingmainthere auto-deploys to Cloudflare Pages (gh run watchto confirm).ln -s "$PWD/skills/<name>" ~/.claude/skills/<name>— the symlink that makes it loadable locally.
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.

claude-skills AGENTS.md is an instructions file published in the GitHub repository shaharsha/claude-skills (5 stars, last pushed 12d ago), licensed MIT.
