v0.1.59

🚀 Release Highlights — v0.1.59 (2026-03-04)

🔄 Smarter Quality Rounds

• Verification Replay Memories: Agents save replayable verification steps (commands, scripts, artifacts) to verification_latest.md, auto-injected into future rounds so the next agent can replay the exact verification pipeline
• Plan-Tracked Improvements: Improvements from each round are auto-added to the task plan, so agents build on prior progress instead of starting fresh
• Enhanced Plan Review: More thorough quality evaluation during plan review phases

✅ Checklist & Evaluation Fixes

• More Accurate Evaluations: Improved evaluation generation config for higher-quality assessments
• Consistent Checklist Behavior: Fixed checklist handling across rounds
• Gemini MCP Compatibility: Tool name normalization for Gemini backends using MCP tools

🔧 Infrastructure

• Subagent Enhancements: Improved coordination, task delegation, and Docker skill write access
• Video Generation Fixes: Cleaner error handling (no silent fallback to animated), restored impact metrics
• Bug Fixes: Answer anonymization fix, quickstart updates
