What problem does it solve?

Scan, evaluate, and catalog large collections of agent skills into a structured JSON file with per-skill evaluations and aggregate statistics to support auditing and comparison across skill libraries.

Core Features & Use Cases

  • Scans local folders or GitHub repositories to locate SKILL.md files and extract frontmatter, structure, script languages, license, and external indicators.
  • Evaluates each skill on standardized dimensions (usage value, security risk, executability, invocability, and more) and merges results into a machine-readable skill catalog.
  • Produces a comprehensive skill-catalog.json with per-skill entries and aggregate statistics for easy filtering and benchmarking.

Quick Start

Run the scanner against your skills directory to generate skill-catalog.json.

FAQPage Schema
How do I catalog and evaluate large collections of agent skills?

To catalog and evaluate agent skills, you scan local folders or GitHub repositories containing SKILL.md files to extract frontmatter, directory structure, and script languages into a structured JSON catalog. The process performs batch scoring on standardized dimensions to support auditing and comparison.

What is included in a skill-catalog.json file?

A skill-catalog.json file contains per-skill entries with extracted frontmatter, script languages, and evaluation scores, alongside aggregate summary statistics. It provides a machine-readable format for easy filtering and benchmarking across your agent skill libraries.

Can I scan GitHub repositories to extract frontmatter from SKILL.md files?

Yes, you can scan GitHub repositories to extract frontmatter from SKILL.md files. The scanning process also extracts directory structure, script languages, license information, and external indicators to build a comprehensive evaluation catalog.

What standardized dimensions are used to evaluate agent skills?

Agent skills are evaluated on standardized dimensions including usage value, security risk, executability, and invocability. These mechanical extraction and batch scoring results merge into a machine-readable catalog for easy filtering and benchmarking.

Does this skill catalog builder scale for large agent skill sets?

Yes, the skill catalog builder scales to large agent skill sets by performing mechanical extraction and batch scoring across local folders or GitHub repositories. It processes each SKILL.md file to produce comprehensive per-skill entries and aggregate statistics without manual intervention.
