FAQPage Schema
How do I automatically catalog all available skills from SKILL.md files?▼

You can catalog skills by scanning all SKILL.md files within the .gaai/core/skills/ directory to automatically generate a derived skills-index.yaml file aggregating their YAML frontmatter metadata.

How does skills metadata aggregation handle duplicate IDs and missing fields?▼

Skills metadata aggregation extracts frontmatter fields like name, description, and category, then reports on total skills scanned, missing required fields, and duplicate IDs to ensure catalog integrity.

What is the best way to maintain an up-to-date skills index for AI agent discovery?▼

The best way to maintain an up-to-date skills index is to run an automated scan of all SKILL.md files, which extracts and organizes metadata by category into a central skills-index.yaml file.

What metadata fields are extracted when building a skills index?▼

When building a skills index, the tool extracts YAML frontmatter fields including name, description, ID, category, track, tags, version, and updated_at, organizing them by category.

Why does my AI agent fail to find newly added custom skills?▼

Your AI agent may fail to find newly added custom skills if the central skills-index.yaml file is outdated, requiring a rescan of SKILL.md files to refresh the catalog and ensure discoverability.
