How does this skill reduce context window costs?

It identifies 'token density' violations and suggests moving deterministic code blocks into scripts, ensuring only essential instructions occupy the active context.

Can this skill help with routing problems?

Yes, it specifically audits Dimension 1 (Frontmatter), checking for trigger phrase authenticity and description framing to ensure the model routes tasks to the skill correctly.

When should I use repair-skill instead of improve-skill?

Use repair-skill for structural fixes, auditing quality, and fixing errors in existing logic. Use improve-skill when you want to add new features or enhance the skill's overall effectiveness.

What is the 'gold standard' used for the audit?

The audit uses reference files for skill anatomy, frontmatter options, and calibration patterns to ensure every skill follows the highly opinionated standards of the Claudest ecosystem.

Audits and repairs Claude Code skills by diagnosing structural violations and identifying gaps against established development standards.

The repair-skill is a specialized diagnostic tool designed to maintain the quality and architectural integrity of Claude Code skills. It performs a rigorous multi-phase audit of a skill's directory or SKILL.md file, evaluating it across seven critical dimensions including frontmatter quality, execution modifiers, and context efficiency. By comparing your skill against a gold standard for anatomy and instruction logic, it generates a structured improvement plan that identifies violations, gaps, and polish opportunities to ensure your skills are reliable, cost-effective, and correctly routed.
