What is skills CLAUDE.md?

Repository instructions for working on a collection of coding-agent skills, including checks, pull requests, and file copying.

They guide code checks, Conventional Commit pull-request titles, copying files, and related repository tasks.

They prevent common contribution errors, such as skipped lint checks or incorrectly formatted pull-request titles.

Token cost

What it costs to keep this loaded

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	$0.02873	$0.02873
Opus 5.5	$0.01149	$0.01149
Sonnet 5.5	$0.00575	$0.00575
Haiku 4.5	$0.00287	$0.00287

Security

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 6d 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.

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.

Changes

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.
