validate-audit

A command that asks a separate auditing agent to review a skill folder against Anthropic’s Claude Code requirements. It checks the skill’s structure, metadata, clarity, and recommended organization.

In plain words
What is it for?
Use it to audit a skill’s SKILL.md file and receive a report with findings and recommendations.
Why use it?
It helps find compliance problems and unclear documentation before others use the skill. The review remains useful even when an earlier check has failed.

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

validate-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 2d 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

Skill Validate Audit

Run comprehensive skill audit using skill-auditor agent (non-blocking).

Usage

/meta-claude:skill:validate-audit <skill-path>

What This Does

Invokes the skill-auditor agent to perform comprehensive analysis against official Anthropic specifications:

  • Structure validation
  • Content quality assessment
  • Best practice compliance
  • Progressive disclosure design
  • Frontmatter completeness

Note: This is non-blocking validation - provides recommendations even if prior validation failed.

Instructions

Your task is to invoke the skill-auditor agent using the Agent tool to audit the skill at $ARGUMENTS.

Call the Agent tool with the following prompt:

I need to audit the skill at $ARGUMENTS for compliance with official Claude Code specifications.

Please review:
- SKILL.md structure and organization
- Frontmatter quality and completeness
- Progressive disclosure patterns
- Content clarity and usefulness
- Adherence to best practices

Provide a detailed audit report with recommendations.

Expected Output

The agent will provide:

  • Overall assessment (compliant/needs improvement)
  • Specific recommendations by category
  • Best practice suggestions
  • Priority levels for improvements

Error Handling

Always succeeds - audit is purely informational.

Even if the skill has validation failures, the audit provides debugging feedback.

Examples

Audit a new skill:

/meta-claude:skill:validate-audit plugins/meta/meta-claude/skills/docker-master
# Output: Comprehensive audit report with recommendations

Audit after fixes:

/meta-claude:skill:validate-audit plugins/meta/meta-claude/skills/docker-master
# Output: Updated audit showing improvements
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.
