Optimize AI Agent Skills with Skill-Sunset Audit Tool

Optimize AI Agent Skills with Skill-Sunset Audit Tool

The Skill-Sunset Audit Tool assists developers in auditing and managing their AI agent skills by analyzing AGENTS.md, CLAUDE.md, and SKILL.md instructions for deterministic drift and identifying model-era obsolescence candidates. It generates evidence-backed, reversible remediation prompts, helping to maintain, modernize, or retire coding-agent instructions effectively.

What this skill does

• Audits agent-related Markdown instructions to detect deterministic drift and potential obsolescence.
• Generates remediation prompts with evidence to guide decision-making on managing skills.
• Facilitates reversible changes without automatically retiring domain knowledge or safety rules.
• Provides immediate feedback through a terminal summary and detailed reviews with `index.html` outputs.
• Supports multilingual outputs, including English and Chinese, via language-specific flags.
• Ensures findings are advisory only, without direct authorization to edit, delete, or deploy changes.

Who it is for

Designed for developers and development teams utilizing AI coding agents such as Claude Code, Cursor, and Codex. This tool is particularly beneficial for those responsible for maintaining and optimizing AI agent skills.

Use cases

• Conducting periodic evaluations of AI agent skills for optimization and relevancy.
• Deciding on retiring outdated AI skills or updating them to align with current model standards.
• Preparing AI skills for integration or migration to new platforms or environments.
• Ensuring AI agent instructions remain compliant with internal guidelines and technical correctness.

Technical details

• Runs using `npx skill-sunset@latest` or local entry scripts for developers testing from a repository.
• Outputs include `index.html` for review, `audit.json` for automation, and language-specific HTML files.
• Checker operates deterministically without reliance on external AI systems like Codex or Claude.
• Adheres to strict boundaries by treating audits as advisory and not permitting unauthorized edits.
