 **PR Agent Consolidation:**
 1. **Unified PR Agent** - Replaced separate `issue-resolver` and `pr-reviewer` agents with single 5-phase `pr` agent
 2. **try-fix Skill** - New skill for exploring independent fix alternatives with empirical testing

 **Prior Infrastructure Consolidation (November 2025):**
 1. **Unified Log Structure** - All logs now under `CustomAgentLogsTmp/` with subdirectories for Sandbox and UITests
