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 | $0.13746 | $0.13746 |
| Opus 5.5 | $0.05498 | $0.05498 |
| Sonnet 5.5 | $0.02749 | $0.02749 |
| Haiku 4.5 | $0.01375 | $0.01375 |
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 today.
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 — 933 lines — stays where its author put it; the contents beside it link to each section on GitHub.
edloidas/skills
A collection of Claude Code and other agents skills following the Agent Skills specification.
Never commit or push changes unless explicitly asked. Never commit directly to the main branch unless explicitly asked.
No AI footers: Do not add "Drafted with AI assistance", Claude Code session links, <sub> attribution lines, a trailing --- rule, or anything similar to commit messages, issue bodies, or PR bodies — including PRs created from the web. No Co-Authored-By trailer crediting an assistant either, and an existing one in git history is not licence to repeat it. Add attribution only when this file, the user's own instructions, or the user's prompt asks for it.
Canonical Repo Instructions
CLAUDE.md is the canonical repo instructions file. The repo root also contains an AGENTS.md
symlink pointing to this file so Codex and other agents read the same instructions.
Edit CLAUDE.md directly. Do not replace the AGENTS.md symlink with a copied file.
Repository Structure
Skills are organized into plugin groups. Each group has a .claude-plugin/plugin.json for auto-discovery and contains related skills:
<group>/
├── .claude-plugin/
│ └── plugin.json # Plugin metadata
└── skills/
└── <skill-name>/ # Canonical skill location — a REAL directory
├── SKILL.md # Required — frontmatter + instructions
├── scripts/ # Optional — executable code
├── references/ # Optional — docs loaded on demand
└── assets/ # Optional — templates, images, data
<group>/skills/<skill-name>/ is the one canonical location for a skill, and it must be
a real directory — never a symlink. Two independent constraints force this:
- Claude Code's plugin loader looks inside the plugin's
skills/directory, not the plugin root. A skill outside<group>/skills/is invisible to the plugin even thoughSKILL.md,plugin.json, and the marketplace entry all exist. - Agent skill CLIs (notably
npx skills) discover skills withreaddir(withFileTypes)+entry.isDirectory(), which is false for a symlink. A symlinked skill directory is invisible to them. They also hard-skip directories namednode_modules,.git,dist,build, and__pycache__— which is why thebuild/group is only reachable through the<group>/skills/path that the marketplace manifest points at.
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.

skills CLAUDE.md is an instructions file published in the GitHub repository edloidas/skills (2 stars, last pushed today), licensed MIT. It adds 13,746 tokens to every session, about $0.0550 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.
