Overview

Implement a Skills Index Registry to enable O(1) skill lookup by ID, establish consistent naming conventions, and provide skill lifecycle governance.

Problem Statement

• 65+ skill-related memory files in .serena/memories/
• Skill discovery requires O(n) linear search across 100+ files
• ~7 new skills added per day (scaling problem)
• No consistent naming convention or governance

Solution

A central registry (skills-index.md) that:

1. Provides single-read skill lookup by ID
2. Groups skills by domain for browsing
3. Establishes skill ID naming convention
4. Defines skill lifecycle (creation → validation → deprecation)

Functional Requirements

User Stories

1. Agent finds skill by ID in one memory read
2. Retrospective agent prevents duplicate skill IDs
3. Planner discovers related skills by domain
4. Skillbook agent identifies deprecated patterns
5. Quality gate validates naming convention

Artifacts

• PRD: PRD-skills-index-registry.md
• Status: Approved (10-Agent Consensus)

Sub-Tasks

• Create skills-index.md with initial skill inventory
• Establish skill ID naming convention documentation
• Create skill lifecycle governance process
• Validate existing skills against naming convention
• Create automation for skill registration

Effort: 8-12 hours (implementer)
