Skill Tuning

Autonomous diagnosis and optimization for skill execution issues.

Pre-load (before execution)

1. **Codebase docs**: If `.workflow/codebase/ARCHITECTURE.md` exists, read for project context 2. **Specs**: `maestro load --type spec --category coding` — load coding conventions 3. **Wiki knowledge**: `maestro search "skill design optimization" --json` — top 5 entries as prior context 4. All optional — proceed without if unavailable

Workflow

| Step | Action | Orchestrator Decision | Output | |------|--------|----------------------|--------| | 1 | `action-init` | status='pending' | Backup, session created | | 2 | `action-analyze-requirements` | After init | Required dimensions + coverage | | 3 | Diagnosis (6 types) | Focus areas | state.diagnosis.{type} | | 4 | `action-agy-analysis` | Critical issues OR user request | Deep findings | | 5 | `action-generate-report` | All diagnosis complete | state.final_report | | 6 | `action-propose-fixes` | Issues found | state.proposed_fixes[] | | 7 | `action-apply-fix` | Pending fixes | Applied + verified | | 8 | `action-complete` | Quality gates pass | session.status='completed' |

Action Reference

| Category | Actions | Purpose | |----------|---------|---------| | **Setup** | action-init | Initialize backup, session state | | **Analysis** | action-analyze-requirements | Decompose user request via Agy CLI | | **Diagnosis** | action-diagnose-{context,memory,dataflow,agent,docs,token_consumption} | Detect category-specific issues | | **Deep Analysis** | action-agy-analysis | Agy CLI: complex/critical issues | | **Reporting** | action-generate-report | Consolidate findings → final_report | | **Fixing** | action-propose-fixes, action-apply-fix | Generate + apply fixes | | **Verify** | action-verify | Re-run diagnosis, check gates | | **Exit** | action-complete, action-abort | Finalize or rollback |

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
