gap-detector

name	gap-detector
description	Standalone gap detection engine that compares installed skills against capability requirements. Use when the collective needs to identify missing skills, generate gap reports, or trigger auto-install proposals.

Gap Detector — Capability Gap Identification

Purpose: Detect gaps between installed skills and capability requirements.

Status: ✅ Implemented (2026-03-24)

Usage

# Scan gaps (human-readable)
./gap-detector.sh --scan

# JSON output (programmatic)
./gap-detector.sh --json

# Generate report
./gap-detector.sh --report

Integration Points

• Curiosity Engine: Gap detection workflow
• Auto-Trigger: Identifies installable gaps
• Capability Mapping: Goal-skill alignment

Gaps detected. Actions triggered. Capability grown. 🦞
