Skill Evolution Manager

Enables skills to automatically improve based on usage patterns, user edits, and success rates. Provides version control with safe rollback capability.

Overview

• Reviewing how skills are performing across sessions
• Identifying patterns in user edits to skill outputs
• Applying learned improvements to skill templates
• Rolling back problematic skill changes
• Tracking skill version history and success rates

Quick Reference

Command	Description
/ork:skill-evolution	Show evolution report for all skills
/ork:skill-evolution analyze <skill-id>	Analyze specific skill patterns
/ork:skill-evolution evolve <skill-id>	Review and apply suggestions
/ork:skill-evolution history <skill-id>	Show version history
/ork:skill-evolution rollback <skill-id> <version>	Restore previous version

How It Works

The skill evolution system operates in three phases:

COLLECT                    ANALYZE                    ACT
───────                    ───────                    ───
┌─────────────┐           ┌─────────────┐           ┌─────────────┐

Subcommands

Each subcommand is documented with implementation details, shell commands, and sample output. Load details: Read("${CLAUDE_SKILL_DIR}/references/evolution-commands.md")

Report (Default)

/ork:skill-evolution — Shows evolution report for all tracked skills with usage counts, success rates, and pending suggestions.

Analyze

/ork:skill-evolution analyze <skill-id> — Deep-dives into edit patterns for a specific skill, showing frequency, sample counts, and confidence scores.

Evolve

/ork:skill-evolution evolve <skill-id> — Interactive review of improvement suggestions. Uses AskUserQuestion for each suggestion (Apply / Skip / Reject). Creates version snapshot before applying.

History

/ork:skill-evolution history <skill-id> — Shows version history with performance metrics per version.

Rollback

/ork:skill-evolution rollback <skill-id> <version> — Restores a previous version after confirmation. Current version is backed up automatically.

File	Purpose	Format
.claude/feedback/edit-patterns.jsonl	Raw edit pattern events	JSONL (append-only)
.claude/feedback/evolution-registry.json	Aggregated suggestions	JSON

Auto-Evolution Safety

Load details: Read("${CLAUDE_SKILL_DIR}/rules/auto-evolution-triggers.md") for full safety mechanisms, health monitoring, and trigger criteria.

Key safeguards: version snapshots before changes, auto-alert on >20% success rate drop, human review required, rejected suggestions never re-suggested.
