What problem does it solve? Agent skills can fail installation due to malformed SKILL.md files, missing resources, or broken sub-scripts, leaving them stuck in an error state. This Skill diagnoses the failure, applies fixes to the installed files, and updates the manifest so the skill becomes usable again. ## Core Features & Use Cases - Error Diagnosis: Analyzes the reported installation error and inspects all files in the skill directory collectively to find the root cause. - Surgical Repair: Fixes issues directly at the installed path, including malformed SKILL.md frontmatter, missing resources, or incorrect sub-scripts. - Manifest Synchronization: Updates the skill's entry in manifest.json by setting status to "installed" and clearing the error field so the UI refreshes automatically. - Use Case: A skill named "data-export" fails to install because its SKILL.md has invalid YAML frontmatter. Use this Skill to fix the frontmatter at the installed path and mark the skill as installed in manifest.json. ## Quick Start Fix the broken skill that failed installation and update its entry in manifest.json to mark it as installed.
