SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Intercepts skill installations to detect overlap with existing skills, analyzes deltas, and offers merge/install/skip options. Use before installing any skill (npx skills add, find-skills suggesting installs, "should I install X"). Also use for on-demand audits when the user says "audit my skills", "check for redundant skills", "skill overlap", or "do I have duplicate skills".

Core Features & Use Cases

  • Intercepts install commands to assess overlap with installed skills
  • Provides delta analysis and merge/install/skip decision flows
  • Supports audit mode to identify redundancies and overlaps

Quick Start

Run the guard before installing any skill to evaluate overlap and avoid duplicates.

Frequently Asked Questions about skill-guard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent duplicate skills during installation?▼

You can check for redundant skills by running an audit command like "audit my skills" or "check for skill overlap". The guard scans local and project-specific directories to identify overlapping skill sets.

How do I check for redundant or overlapping skills in my project?▼

You can check for redundant skills by running an audit command like "audit my skills" or "check for skill overlap". The guard scans local and project-specific skill directories to identify and analyze overlapping skill sets.

How does skill overlap detection work with SKILL.md files?▼

You can merge overlapping skills during installation by choosing the merge option when the guard detects a delta. It provides a decision flow to install, merge, or skip the incoming skill based on the analysis.

Can I merge skills instead of skipping duplicate installations?▼

You can merge overlapping skills during installation by choosing the merge option when the guard detects a delta. It provides a decision flow to install, merge, or skip the incoming skill based on the analysis.

When should I run a skill overlap audit on my local skill set?▼

You should run a skill overlap audit before installing any new skill or when you notice redundant capabilities. Use it on-demand when you suspect duplicate skills exist across local and project-specific directories.
