+#### Dreamer
+- Default branch prefix: `claude-task/` → `matrix-dreamer/`
+- New config section `dreamer.worktree` and `dreamer.execution` for defaults
+
+#### Review Skill (`/matrix:review`)
+- 4-agent architecture: Detection → Impact → Triage → Remediation
+- Tiered output (critical/important/noise) with confidence scores

 # Matrix Code Review
 
-Perform a comprehensive, context-aware code review using Matrix's review pipeline with full index integration.
+Perform comprehensive, context-aware code review using 4-agent architecture with 95% false positive reduction.
 
 > **Tip:** This skill runs in a **forked context** for an unbiased perspective - similar to how a human reviewer would approach the code for the first time.

 ## Modes
 
 ### Default Mode (Comprehensive)
-Full 5-phase review pipeline with maximum index utilization:
-- Blast radius analysis via `matrix_find_callers`
-- Symbol lookup via `matrix_find_definition` and `matrix_search_symbols`
-- Memory recall via `matrix_recall` for relevant past solutions
-- Deep security and edge case analysis
-- ~10+ comments, thorough coverage
+Full 4-agent review pipeline with maximum index utilization:
+- Detection: Security vulns, runtime issues, breaking changes
+- Impact: Transitive blast radius (2-3 levels), service boundaries, test coverage
+- Triage: Tier classification, >80% signal ratio target
+- Remediation: Context-aware fixes matching codebase patterns
 
 ### Lazy Mode (Quick)
-Single-pass review for fast feedback:
-- Direct code inspection only
-- No index queries (faster)
-- Main issues only
-- ~2-3 comments
+Detection agent only:
+- Direct code inspection
+- Critical issues only (Tier 1)
+- ~2-3 comments, no blast radius
 
 ## Review Pipeline
 
-Follow the 5-phase review pipeline detailed in `references/review-phases.md`:
+Follow the 4-agent orchestration detailed in `references/review-phases.md`:
+
+1. **Orchestrator** - Parse target, dispatch agents, aggregate results
+2. **Detection Agent** - Find security, runtime, breaking, logic issues
+3. **Impact Agent** - Calculate transitive blast radius, test coverage
+4. **Triage Agent** - Classify tiers, calibrate confidence, filter noise
+5. **Remediation Agent** - Generate fixes, check regression risk
 
-1. **Phase 1: Context Mapping** - Calculate blast radius, find callers, build dependency graph
-2. **Phase 2: Intent Inference** - Classify change type, summarize purpose
-3. **Phase 3: Socratic Questioning** - Generate probing questions about edge cases, errors, security
-4. **Phase 4: Targeted Investigation** - Check patterns, verify assumptions, research
-5. **Phase 5: Reflection & Consolidation** - Generate final review with confidence score
+**Early exit:** If Detection finds nothing critical, skip Impact/Triage depth.
