.agents/skills/list-skills/SKILL.md

list-skills is a skill for Claude Code, Codex from julien777z/code-review-action. It costs 40 tokens per session (293 once invoked), scanned A, a copy of list-rules, MIT.

A command for comparing the shared coding-agent skills stored across a defined group of local repositories.

In plain words
What is it for?
It helps audit skill coverage, merge repository names for shared skills, and report conflicting versions of the same skill.
Why use it?
It shows which repositories contain each skill and reveals when the same skill has different instructions in different places.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is julien777z/code-review-action's own configuration. It tells Claude Code and Codex how to work on code-review-action itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything code-review-action configures →

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.

Security

Grade A, and why

list-skills 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.

Origin

This is a copy

88% identical to list-rules — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

List Skills

Dependencies

  • coordinate-repositories — identifies the bounded repository collection and safely gathers the canonical artifacts.

Read each applicable repository's canonical .agents/skills/<name>/SKILL.md files. Exclude repositories whose primary purpose is developing, packaging, testing, or operating the agent-synchronization system itself unless the user explicitly includes them.

For each skill name, merge the repository names that contain it. Compare complete canonical SKILL.md text, including frontmatter. Group identical texts and use the largest group as the baseline. If any other group exists, report every repository outside that baseline as having conflicting language. If two or more groups tie for largest, report all tied groups as conflicting rather than choosing an arbitrary baseline.

Output

Return only these headings and sorted Markdown lists, with no status summary or extra prose:

Skills

- skill-name — (repo-one, repo-two)

## Conflicting Skill Language

- skill-name
  - Baseline: repo-one, repo-two
  - Different language: repo-three

Omit ## Conflicting Skill Language when no differences exist. If no skills exist, return - None under Skills.

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.
