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 | $0.00353 | $0.00353 |
| Opus 5 | $0.00177 | $0.00177 |
| Sonnet 5 | $0.00071 | $0.00071 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
claude-code-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 9d 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
claude-code-skills repo
This repo contains Claude Code skills used across multiple projects.
Structure
skills/
<skill-name>/
SKILL.md # Required — frontmatter + instructions
scripts/ # Optional — executable helpers
references/ # Optional — docs loaded on demand
assets/ # Optional — templates, fonts, etc.
Symlinks in ~/.claude/skills/ point into skills/ here.
Making skill changes
Never edit skills directly on main. All changes go through branches.
Branch naming: skill/<skill-name>/<short-kebab-description>
Commit format:
skill(<skill-name>): <imperative description>
Context: <what session/task revealed this gap>
To review a pending skill branch before merging:
git diff main skill/<skill-name>/<desc>
git log main..skill/<skill-name>/<desc> --oneline
Skill improvement protocol
Claude Code will propose patches to skills during working sessions when it detects a gap or fix. The flow is always: propose → you approve → branch + commit → you merge.
Claude will never commit to main directly. It will never commit without your explicit approval.
Adding a new skill
- Create
skills/<new-skill-name>/SKILL.mdwith YAML frontmatter (name,description) - Add a symlink:
ln -s ~/Projects/claude-code-skills/skills/<new-skill-name> ~/.claude/skills/<new-skill-name> - Use the
skill-creatorskill for drafting, testing, and iterating
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-code-skills CLAUDE.md is an instructions file published in the GitHub repository mouchegmouradian/claude-code-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 353 tokens to every session, about $0.0018 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.
