Preset Evaluation Summary

Date: 2026-01-15 (Updated) Evaluator: 🧪 Preset Evaluator (Claude Agent) Status: COMPLETE - All identified bugs fixed, all tests pass

What Was Accomplished

✅ Blockers Resolved

1. BUG-001: CLI Argument Mismatch - FIXED

   • Evaluation script was passing unsupported -a flag to Ralph
   • Fixed by creating merged config with backend settings
   • All evaluations can now start successfully

2. BUG-002: YAML Format Mismatch - FIXED

   • All 13 preset files had incorrect default_publishes format
   • Changed from array ["event"] to string "event" format
   • Config parsing now works correctly

🔍 Additional Issues Identified & Fixed

3. BUG-003: Idle Timeout Too Aggressive - RESOLVED

   • Evaluations timeout after 30s of perceived inactivity
   • Fixed in evaluate-preset.sh by setting idle_timeout_secs: 120

4. BUG-008: docs.yml orphaned event - FIXED

   • review.revision event had no handler
   • Fixed: writer hat now triggers on review.revision

5. BUG-009: performance-optimization.yml ambiguous - FIXED

   • profiler hat had no default_publishes
   • Fixed: Added default_publishes: "baseline.measured"

📊 Evaluation Progress

• Presets Validated: 21/21 (all parse correctly via dry-run)
• Bugs Found: 9 total (9 fixed)
• Tests Passing: 72/72 (all cargo tests pass)
• UX Improvements Identified: 5
• Enhancement Ideas: 3

Key Findings

What Works Well

1. Hat Routing: Events correctly trigger appropriate hats
2. Hat Instructions: Agents understand their roles clearly
3. File Operations: Agents successfully create files in sandbox
4. Role Separation: Hats stay focused on their specific responsibilities

What Needs Improvement

1. Event Visibility: No real-time view of event publication
2. Progress Indicators: Long-running evaluations have no progress feedback
3. Idle Detection: Too aggressive, interrupts legitimate agent thinking time
4. Completion Signals: Unclear when workflow is stuck vs. progressing

Recommendations

Immediate (P0)

1. Fix idle timeout in evaluation script (increase to 120s or disable)
2. Add event log monitoring to show event flow in real-time
3. Verify Kiro CLI correctly writes events to .agent/events.jsonl

Short-term (P1)

1. Add progress indicators to evaluation script
2. Create preset validation tool (syntax, event graph, cycles)
3. Improve preset documentation with troubleshooting guide

Future (P2)

1. Build preset testing framework with unit/integration tests
2. Create preset development tools (builder, visualizer)
3. Add observability features (event flow diagrams, timelines)

Files Modified

1. tools/evaluate-preset.sh - Fixed CLI argument handling, idle timeout
2. presets/*.yml (13 files) - Fixed default_publishes format
3. presets/docs.yml - Added review.revision trigger to writer hat
4. presets/performance-optimization.yml - Added default_publishes to profiler
5. presets/COLLECTION.md - Updated documentation
6. tools/preset-evaluation-findings.md - Comprehensive findings document
7. .agent/preset-eval-scratchpad.md - Session tracking

Architecture Clarification

The 21 presets are organized into two categories:

Standalone Presets (16 presets)

Have starting_event in event_loop config - Ralph auto-publishes this event to start the workflow:

• tdd-red-green, adversarial-review, socratic-learning, spec-driven
• mob-programming, scientific-method, code-archaeology, performance-optimization
• api-design, documentation-first, incident-response, migration-safety
• research, review, debug, gap-analysis

Planner-Dependent Presets (5 presets)

Require Ralph's internal Planner component to inject events:

• feature, feature-minimal, deploy, docs, refactor

This is BY DESIGN - these presets work with Ralph's planning system which creates tasks and injects build.task or similar events.

Next Steps

1. Apply BUG-003 fix DONE
2. Complete validation of all presets DONE (all 21 parse correctly)
3. Consider creating a ralph validate-preset subcommand
4. Update preset documentation to clarify standalone vs Planner-dependent
