System Reviewer

Overview

system-reviewer performs meta-level reviews of the skill development ecosystem itself, assessing the health and effectiveness of the entire system rather than individual skills.

Purpose: Meta-level ecosystem assessment and system optimization

The 5 System Review Operations:

1. Ecosystem Health Check - Assess overall ecosystem quality and completeness
2. Toolkit Effectiveness Review - Evaluate how well the toolkit works
3. Process Efficiency Review - Review development processes for optimization
4. Coverage Gap Analysis - Identify missing capabilities or skills
5. System Optimization Recommendations - Recommend system-level improvements

Key Distinction: Reviews the SYSTEM, not individual skills

When to Use

• Periodic ecosystem health checks (monthly/quarterly)
• After completing major layers (Layer 2, 3, 4, 5)
• When suspecting systemic issues (not individual skill problems)
• Planning next ecosystem developments
• Optimizing the development system itself

Operations

Operation 1: Ecosystem Health Check

Purpose: Assess overall ecosystem quality, completeness, and consistency

Process:

1. Count and Categorize Skills

   • Total skills built
   • Skills per layer
   • Pattern distribution (workflow/task/reference)
   • Completion percentage

2. Assess Structural Quality

   • Run review-multi validation on all skills
   • Calculate average quality scores
   • Identify outliers (very high/low quality)
   • Check consistency across ecosystem

3. Evaluate Completeness

   • Are all planned layers complete?
   • Are there gaps in capabilities?
   • Is toolkit comprehensive?
   • Missing critical functionality?

4. Check Integration

   • Do skills work together well?
   • Are there integration issues?
   • Workflow compositions effective?
   • Dependencies clear and working?

5. Generate Health Report

   • Overall health score (healthy/good/needs attention/critical)
   • Strengths (what's working well)
   • Weaknesses (what needs improvement)
   • Trends (improving/stable/degrading)

Outputs:

• Ecosystem health score
• Skill inventory and metrics
• Quality assessment aggregate
• Completeness analysis
• Integration assessment
• Health report with recommendations

Time Estimate: 1-2 hours

Example:

Ecosystem Health Check: 2025-11-07
====================================

Skill Inventory:
- Total Skills: 23
- Layer 2: 10/10 (100%)
- Layer 3: 7/7 (100%)
- Layer 4: 6/6 (100%)
- Layer 5: 0/5 (0%)

Quality Assessment:
- Average Structure Score: 5.0/5.0 (all 23 skills Grade A)
- Quality Range: 5/5 (no variation - excellent consistency)
- Quick Reference Coverage: 100% (all 23 skills)
- Anti-Patterns: 10 total identified, 3 fixed

Completeness:
✅ Research capability: Complete (skill-researcher + research-workflow)
✅ Planning capability: Complete (planning-architect + task-development + planning-workflow)
✅ Execution capability: Complete (todo-management + momentum-keeper)
✅ Quality capability: Complete (review-multi + skill-validator + skill-tester + review-workflow)
✅ Improvement capability: Complete (skill-reviewer + skill-updater + improvement-workflow)
⬜ Self-improvement: 0% (Layer 5 not built)
⬜ Comprehensive testing: Partial (skill-tester exists, testing-validator missing)

Integration Assessment:
✅ Skills compose well (development-workflow, review-workflow, improvement-workflow working)
✅ Dependencies clear (YAML + documentation)
✅ Workflows effective (proven through usage)

Ecosystem Health: ✅ HEALTHY

Strengths:
- 100% structural excellence
- Complete Layers 2-4
- Validated continuous improvement cycle
- 85% efficiency gain proven

Weaknesses:
- Layer 5 incomplete (missing self-improvement automation)
- testing-validator missing (validation incomplete without it)
- Some minor anti-patterns in 4 skills (vague validation criteria)

Trends:
✅ Improving: Efficiency compounding, quality consistent, standards evolving
✅ Stable: Structural quality (all 5/5)

Recommendations:
1. [High] Complete Layer 5 for full self-improvement capability
2. [Medium] Build testing-validator for complete validation suite
3. [Low] Refine vague validation criteria in 4 skills

Operation 2: Toolkit Effectiveness Review

Purpose: Evaluate how well the development toolkit enables skill building

Process:

1. Measure Efficiency Gains

   • Build time progression (skills 1-23)
   • Efficiency vs baseline
   • Time saved calculation
   • Trend analysis (improving/plateauing?)

2. Assess Tool Utilization

   • Which tools used most? (high value)
   • Which tools rarely used? (low value or unknown)
   • Which tools most effective? (biggest impact)
   • Are there gaps? (missing tools)

3. Evaluate Workflow Effectiveness

   • Is development-workflow actually used?
   • Does it save time as promised?
   • Are workflows followed or bypassed?
   • Improvements to workflows needed?

4. *Check Tool Quality
