system-reviewer

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

• 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

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

1. Assess Structural Quality

- Run review-multi validation on all skills

- Calculate average quality scores

- Identify outliers (very high/low quality)

- Check consistency across ecosystem

1. Evaluate Completeness

- Are all planned layers complete?

- Are there gaps in capabilities?

- Is toolkit comprehensive?

- Missing critical functionality?

1. Check Integration

- Do skills work together well?

- Are there integration issues?

- Workflow compositions effective?

- Dependencies clear and working?

1. 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:

```

⬜ 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?)

1. 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)

1. Evaluate Workflow Effectiveness

- Is development-workflow actually used?

- Does it save time as promised?

- Are workflows followed or bypassed?

- Improvements to workflows needed?

1. Check Tool Quality

- Are tools themselves high quality?

- Do they achieve stated purposes?

- User satisfaction with tools?

- Tools needing improvement?

1. Generate Toolkit Assessment

- Most valuable tools

- Least utilized tools

- Effectiveness metrics

- Improvement opportunities

Outputs:

• Toolkit effectiveness assessment
• Tool utilization metrics
• High-value vs low-value tools identified
• Toolkit improvement recommendations

Time Estimate: 1-1.5 hours

Operation 3: Process Efficiency Review

Purpose: Review development processes for optimization opportunities

Process:

1. Document Current Processes

- How are skills currently built?

- What's the typical workflow?

- What steps are always followed?

- What steps are sometimes skipped?

1. Measure Process Metrics

- Average build time per skill complexity

- Rework rate (how often redo work?)

- Blocker frequency (how often stuck?)

- Completion rate (how many finished?)

1. Identify Bottlenecks

- Longest steps in process

- Most frequent blockers

- Highest rework areas

- Inefficient patterns

1. Assess Automation

- What's automated? (scripts, workflows)

- What's manual? (still required human input)

- Automation opportunities? (could be automated)

- Automation effectiveness? (actually saves time?)

1. Generate Process Recommendations

Time Estimate: 1-2 hours

---

1. Regular Health Checks

Practice: Run ecosystem health check monthly or after major milestones

Rationale: Early detection of systemic issues prevents compounding

2. Data-Driven Assessment

Practice: Use metrics and evidence, not opinion

Rationale: Objective assessment enables better decisions

3. System-Level Focus

Practice: Focus on ecosystem patterns, not individual skill issues

Rationale: system-reviewer is for systemic issues, review-multi for individual skills

4. Act on Findings

Practice: Use recommendations to guide next development priorities

Rationale: Reviews without action don't improve anything
