Greptile Summary

This PR introduces the AI Skills extension for Raycast, enabling users to create and manage custom AI skills with semantic routing for automatic skill selection. The extension provides a complete suite of features including:

• Skill Management UI: Beautiful interface to create, edit, enable/disable, and delete skills
• Semantic Routing: AI-powered intelligent skill selection using configurable fast LLMs
• Multiple Skills Folders: Support for organizing skills across different folders (personal, project-specific)
• AI Tools: Comprehensive set of tools for use in AI Chat (@ai-skills commands)
• Storage: LocalStorage-based persistence with YAML frontmatter skill format

Code Quality: The implementation is well-structured with proper error handling, type safety, and no critical security issues. Storage operations use secure file APIs and proper permission checks. The routing model selection is sophisticated with automatic fallbacks.

Configuration: All settings properly configured including Prettier standards (printWidth: 120), TypeScript strict mode, and proper ESLint configuration. CHANGELOG follows Raycast standards with {PR_MERGE_DATE} placeholder.

Note: The extension uses media/ folder for screenshots instead of metadata/ folder. For view-type commands in the Raycast store, professional Raycast-styled screenshots in a metadata/ folder are recommended.

Confidence Score: 4/5

• This PR is safe to merge with high confidence. No critical issues detected; only minor suggestion regarding metadata folder structure for store presentation.
• The extension demonstrates solid engineering practices with proper error handling, type safety, secure file operations, and no logical vulnerabilities. The code is well-organized and the feature set is comprehensive. The score of 4/5 reflects the high quality implementation with only a minor architectural consideration about store presentation assets remaining.
• Consider adding a metadata/ folder with Raycast-styled screenshots for professional store presentation (not a blocker for functionality)

Important Files Changed

Filename	Overview
extensions/ai-skills/package.json	Extension manifest with proper configuration, all required fields present, valid commands and tools. Minor: missing metadata folder with Raycast-styled screenshots as required for view-type commands.
extensions/ai-skills/src/storage.ts	Storage layer implements proper skill persistence, folder management, YAML parsing, and file operations. All error handling is appropriate and no security issues detected.
extensions/ai-skills/src/manage-skills.tsx	Main UI component with comprehensive skill management features including enable/disable, edit, delete, and folder configuration. No critical issues, logic is sound, though folder exists check could be more robust.
extensions/ai-skills/src/models.ts	Model selection logic properly filters fast models dynamically from AI.Model enum, handles deprecated models, and provides sensible defaults.
extensions/ai-skills/src/tools/use-skills.ts	Semantic routing tool correctly implements skill selection, handles errors gracefully, and provides helpful guidance when no routing model is configured.

   style: This extension has a view-type command (mode: "view" on line 27), so it requires a metadata/ folder containing Raycast-styled screenshots. Currently, the extension uses media/ folder for screenshots. Consider adding a metadata/ folder with professional Raycast-styled screenshots for better presentation in the store.
