What specific errors does the Freebie Skill Compliance Auditor detect?

This auditor scans for syntax errors in YAML frontmatter, ensures your descriptions use the mandatory 'Use when...' trigger format, and flags potential security risks like hardcoded API keys or dangerous shell commands.

Is this tool compatible with all AI agent marketplaces?

This skill is designed to validate SKILL.md files against the standard schemas used by modern AI agent marketplaces and frameworks, ensuring your submission meets production requirements.

What happens if my file fails the compliance check?

The auditor provides a structured Pass/Fail scorecard that highlights the exact line and type of error, along with clear remediation steps to help you fix the issue immediately.

Can this skill help me identify security risks before I publish my code?

Yes, besides standard syntax, it performs a security sweep for secrets, credentials, and high-risk command patterns that could lead to unauthorized access or system vulnerabilities.

Can I use this for internal team development or only for marketplace submissions?

Absolutely. You can use it to audit open-source prompt repositories or to standardize contributions from multiple developers, ensuring everyone follows the same documentation standards.

Example session with this skill installed

Audit my SKILL.md file. It has name: test-skill, version: 1.0, and a description saying 'This skill helps users write code.' I also included a dummy AWS key: AKIAIOSFODNN7EXAMPLE.

I have completed the compliance audit for your SKILL.md file. Below is the scorecard and the identified security risks.

Compliance Audit Results

Category	Status	Details
YAML Frontmatter	FAIL	Missing mandatory closing `---` or malformed block.
Trigger Format	FAIL	Description must start with "Use when the user asks to...".
Version Schema	PASS	Version 1.0 is valid.
Security Scan	FAIL	Found a high-risk credential pattern (AWS Access Key).

Security Flags

Flag 1: AKIAIOSFODNN7EXAMPLE detected. This appears to be a hardcoded AWS Access Key. Hardcoded credentials will result in an immediate marketplace rejection and pose a severe security risk. Remove and use environment variables instead.

Recommended Fixes

Change your description to: description: Use when the user asks to write, debug, or refactor code snippets.
Wrap your metadata in triple-dashes at the top and bottom of the file.
Sanitize the file by removing all raw strings that resemble API keys or private tokens.

Next steps

Apply the description syntax fix to meet marketplace ingestion requirements.
Run a git secret scan if this file was already committed to a repository.

About this skill

The problem

Broken frontmatter or missing trigger phrases cause AI skills to fail during ingestion. Manual security audits for hardcoded credentials in markdown files are prone to human error.

What it does

Validates YAML frontmatter for mandatory name and version fields.
Verifies the description follows the specific "Use when..." trigger-based syntax.
Scans for hardcoded API keys, secrets, and high-risk shell commands.
Generates a structured Pass/Fail scorecard with specific remediation steps.

Why this beats prompting it yourself

Writing a prompt that catches every syntax nuance and security edge case takes hours of testing. This skill uses pre-defined marketplace schemas to ensure your file is production-ready without multiple manual revisions.

Use cases

Pre-publish validation for new AI agent skills.
Security auditing for open-source prompt repositories.
Standardizing developer contributions in a multi-author marketplace.
