agent-sync-action: Skill for Claude Code

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

list-rules is a skill for Claude Code, Codex from julien777z/agent-sync-action. It costs 40 tokens per session (287 once invoked), scanned A, original, MIT.

A rule-listing tool compares the official rule files in a defined group of local code repositories. It groups matching rule text and reports repositories where the wording differs.

In plain words
What is it for?
Finding which repositories contain each rule, checking whether their rule text matches, and reporting differences.
Why use it?
It removes the need to inspect every repository and compare rule files by hand. It also highlights conflicting versions of shared rules.

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/agent-sync-action's own configuration. It tells Claude Code and Codex how to work on agent-sync-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 agent-sync-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-rules 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.

What it actually says

List Rules

Dependencies

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

Read each applicable repository's canonical .agents/rules/<name>.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 rule name, merge the repository names that contain it. Compare complete canonical rule 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:

Rules

- rule-name — (repo-one, repo-two)

## Conflicting Rule Language

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

Omit ## Conflicting Rule Language when no differences exist. If no rules exist, return - None under Rules.

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.
