## REVIEWER AUDIT - APPROVED ✓ ### Implementation Review **Scope**: Exactly 3 files modified, all directly related to ticket scope ✓ **Acceptance Criteria - All Met**: 1. ✓ `set_agent_status` tool exists in MCP bridge (`mcp-bridge/src/tools/index.ts`) 2. ✓ Only orchestrator agents can successfully call the tool (authorization enforced) 3. ✓ Cannot update human agent status 4. ✓ Updates both `availability_status` and `availability_updated_at` 5. ✓ Returns updated agent object with all relevant fields 6. ✓ Comprehensive test coverage added (106 new lines) ### Security Review **Authorization**: - Orchestrator-only check: `unless current_agent.agent_type == "orchestrator"` ✓ - Human agent protection: `if target_agent.agent_type == "human"` ✓ - Project isolation: `Agent.find_by(id: ..., project_id: current_agent.project_id)` ✓ - Status validation: `unless %w[busy idle].include?(params[:status])` ✓ ### Test Coverage (7 scenarios, all passing) - Sets status to busy ✓ - Sets status to idle ✓ - Rejects non-orchestrator callers ✓ - Rejects human agent updates ✓ - Validates status enum ✓ - Enforces project isolation ✓ - Updates timestamp correctly ✓ ### Bonus: Bug Fix Included The PR also fixes an inconsistency: `list_members` role enum now includes "planner" which is already defined in `Agent` model (validation and capabilities) but was missing from the MCP tool filter. ### Code Quality - Follows existing MCP handler patterns ✓ - Consistent error response format ✓ - No security vulnerabilities identified ✓ **Status**: PASS_AUDIT - Ready for human approval
