Core Issues Detected

Problem Categories (Detailed Specs)

See [specs/problem-taxonomy.md](specs/problem-taxonomy.md) for:

• Detection patterns (regex/checks)
• Severity calculations
• Impact assessments

Tuning Strategies (Detailed Specs)

See [specs/tuning-strategies.md](specs/tuning-strategies.md) for:

• 10+ strategies per category
• Implementation patterns
• Verification methods

Workflow

State Management

Single source of truth: .workflow/.scratchpad/skill-tuning-{ts}/state.json

{
  "status": "pending|running|completed|failed",
  "target_skill": { "name": "...", "path": "..." },
  "diagnosis": {
    "context": {...},
    "memory": {...},
    "dataflow": {...},
    "agent": {...},
    "docs": {...},
    "token_consumption": {...}
  },
  "issues": [{"id":"...", "severity":"...", "category":"...", "strategy":"..."}],
  "proposed_fixes": [...],
  "applied_fixes": [...],
  "quality_gate": "pass|fail",
  "final_report": "..."
}

See [phases/state-schema.md](phases/state-schema.md) for complete schema.

Orchestrator Logic

See [phases/orchestrator.md](phases/orchestrator.md) for:

• Decision logic (termination checks → action selection)
• State transitions
• Error recovery

Key Principles

1. Problem-First: Diagnosis before any fix
2. Data-Driven: Record traces, token counts, snapshots
3. Iterative: Multiple rounds until quality gates pass
4. Reversible: All changes with backup checkpoints
5. Non-Invasive: Minimal changes, maximum clarity

Usage Examples

# Basic skill diagnosis
/skill-tuning "Fix memory leaks in my skill"

# Deep analysis with Gemini
/skill-tuning "Architecture issues in async workflow"

# Focus on specific areas
/skill-tuning "Optimize token consumption and fix agent coordination"

# Custom issue
/skill-tuning "My skill produces inconsistent outputs"

Output

After completion, review:

• .workflow/.scratchpad/skill-tuning-{ts}/state.json - Full state with final_report
• state.final_report - Markdown summary (in state.json)
• state.applied_fixes - List of applied fixes with verification results
