agent-audit

agent-audit is a skill for Claude Code from bdfinst/agentic-dev-team. It costs 74 tokens per session (7,375 once invoked), scanned A, original, MIT.

A structural checker for code-review agents, skills, and hooks that compares them with required compliance patterns.

In plain words
What is it for?
It is used to audit agent, skill, and hook definitions and verify their contracts and registry entries.
Why use it?
It catches missing or incorrectly shaped files and configurations before they cause problems in the evaluation system.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the dev-team plugin — 98 skills, 54 agents, 4 hooks shipped together

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

agent-audit 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 1mo 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.

Agent Audit

Role: orchestrator. This skill performs mechanical compliance checks — pattern matching against known-good structure.

You have been invoked with the /agent-audit skill. Audit agents and skills for compliance with the eval system patterns documented in .claude/docs/eval-system.md.

Monorepo-relative by design (#1637). Steps 8 and 2e's scripts/validate_agent_contract.py and scripts/check_registry_sync.py calls are intentionally bare, not a dangling-path defect. check_registry_sync.py hardcodes plugins/dev-team and checks this marketplace repo's own registry — it exists only at this repo's root, so no ${CLAUDE_PLUGIN_ROOT} path could ever resolve it. validate_agent_contract.py's repo-root copy is a thin wrapper delegating to plugins/marketplace-dev/scripts/validate_agent_contract.py (which does ship and is portable) — but there is no single variable spanning two independently-installed plugins, so the wrapper is reachable only from this monorepo checkout, where both plugin directories are siblings on disk. Both calls only make sense run from a dev-team-monorepo-shaped checkout (this repo, or a structural fork), never an installed plugin cache. See tests/repo/test_agent_implemented_by_resolves.py's INTENTIONAL_BARE_INVOCATION set, which checks the "does not ship" premise mechanically. (#1652 landed a Bash(...) grant in this skill's allowed-tools frontmatter covering all three of these script steps — including verify_tier.py below — by their exact bare/repo-relative invocation form, so they execute today; see the allowed-tools block above.)

Orchestrator constraints

  1. Check structure, not semantics. Verify required sections, fields, and patterns exist. Do not evaluate whether detection rules are good — that's agent-eval's job.
  2. Deterministic checks only. Every check should be reproducible: does the field exist? Is the format correct? Does the section match the expected pattern?
  3. When --fix is used, apply minimal structural fixes. Insert missing sections/fields using templates. Do not rewrite existing content.
  4. Be concise. Output the report table and action items. No preambles, no per-file narration, no restating what was checked.

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.
