Skill Updater

Overview

skill-updater provides systematic workflow for applying improvements to existing Claude Code skills based on review findings, user feedback, or identified opportunities.

Purpose: Systematic skill improvement and enhancement

Integration:

• review-multi → identifies improvements
• skill-reviewer → finds opportunities
• skill-updater → applies changes systematically
• skill-validator → validates changes

Update Workflow (5 steps):

1. Plan Updates - Review recommendations, prioritize, plan changes
2. Backup Skill - Save current version before changes
3. Apply Changes - Implement improvements systematically
4. Validate Changes - Ensure improvements effective, no regressions
5. Document Updates - Record what changed and why

When to Use

• Applying review-multi recommendations
• Implementing user feedback
• Enhancing skill based on skill-reviewer findings
• Systematic improvements across skills
• Version updates (v1.0 → v1.1)

Update Workflow

Step 1: Plan Updates

Process:

1. Gather improvement recommendations (from reviews, feedback)
2. Prioritize: Critical → High → Medium → Low
3. Estimate effort per improvement
4. Plan update sequence
5. Set success criteria

Step 2: Backup Skill

Process:

Copy# Create backup
cp -r .claude/skills/skill-name .claude/skills/skill-name.backup-$(date +%Y%m%d)

# Or use git
git add .claude/skills/skill-name
git commit -m "Backup before updates"

Step 3: Apply Changes

Process:

1. Start with highest priority
2. Make one improvement at a time
3. Test after each change
4. Mark as complete
5. Move to next

---

Step 4: Validate Changes

Process:

1. Run skill-validator (structure, content, pattern)
2. Compare before/after (metrics, quality)
3. Test in real scenario (usability)
4. Verify no regressions

Step 5: Document Updates

Process:
