Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02149 | $0.02149 |
| Opus 5 | $0.01074 | $0.01074 |
| Sonnet 5 | $0.00430 | $0.00430 |
| Haiku 4.5 | $0.00215 | $0.00215 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skills
Personal skills for agentic coding with Claude Code.
Checks
Run the lint gate before committing (also enforced in CI by
.github/workflows/lint.yml):
pre-commit run --all-files
It covers ruff (Python), shfmt + shellcheck (shell), markdownlint-cli2 (Markdown),
actionlint + zizmor (workflows), and the SKILL.md frontmatter validator. Install
the git hook once with pre-commit install.
Pull requests
The PR title must be a Conventional Commit, enforced by
.github/workflows/lint-pr-title.yml. This is a separate check from the
commit-message hook, and it reads the PR title only — a valid commit message
does not imply a valid PR title, so a title typed by hand at gh pr create
time is the usual thing that fails.
A skill name is a scope, not a type. The type prefix is mandatory:
feat(pm-deepen): adopt the branch the caller prepared # correct
pm-deepen: adopt the branch the caller prepared # fails: no type
Allowed types: feat, fix, docs, style, refactor, perf, test,
build, ci, chore, revert. Fix a rejected title in place with
gh pr edit <n> --title "..." — the check re-runs on edit, no push needed.
cp
Slash command /cp that commits and pushes changes to the current branch, running only the pre-commit checks described in the project's CLAUDE.md (or AGENTS.md) — nothing more, nothing less.
codex-2nd-opinion
Slash command /codex-2nd-opinion that invokes OpenAI Codex CLI (GPT-5.4) to get an independent second opinion on any discussion, plan, or code. Presents both Claude's and Codex's perspectives with a structured, fair comparison.
auto-merge-dependabot
Slash command /auto-merge-dependabot that reviews all open Dependabot PRs in the current repository, assesses each for risk (version bump type, CI status, file scope), and automatically merges safe ones while flagging those that need manual review.
brainstorming
Skill that guides collaborative design before implementation. Explores user intent through one-at-a-time questions, proposes 2-3 approaches with trade-offs, presents the design incrementally for approval, then writes and commits a spec document. Stops at the approved spec — does not auto-trigger implementation. Forked from obra/superpowers brainstorming skill with all references to other superpowers skills removed.
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 pmatos/skills (2 stars, last pushed yesterday), licensed MIT. It adds 2,149 tokens to every session, about $0.0107 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.
