## 1. Executive Summary

This cross-code review evaluated the latest fix commit (`d2a8247`) and follow-up fix (`57bc1b2`) in the `multi-agent-mux-resume` skill.
- **Commit `d2a8247`**: Resolved silent fallback bugs in `update_yaml_resumed.sh` by properly passing `--workspace`, `--role`, and epoch timestamp when auto-creating missing session entries during resume.
- **Commit `57bc1b2`**: Fixed an `unbound variable` bash error under `set -u` by declaring `AGENT=""` at script initialization.

All changes adhere to project safety guidelines, pass schema validation, and maintain complete protocol alignment.

## 2. Review Findings & Technical Analysis

### 2.1 Commit `d2a8247`: Workspace, Role, and Epoch Passing
- **Files Modified**:
  - `.agents/skills/multi-agent-mux-resume/scripts/resume_session.sh`
  - `.agents/skills/multi-agent-mux-resume/scripts/update_yaml_resumed.sh`
- **Analysis**:
  - **CLI Argument Expansion**: Added `--workspace` and `--role` parsing to `update_yaml_resumed.sh`, and updated `resume_session.sh` to forward `--workspace "$WORKSPACE"`.
  - **Pattern-Based Role & Agent Inference**: Accurately infers `ROLE` (`planner`, `reviewer`, `creator`) and `AGENT` (`claude`, `agy`, `hermes`, `cline`) from session name patterns (e.g., `*-planner-*`, `*-reviewer-*`) when omitted.
  - **Timestamp Accuracy**: Calculates `NOW_EPOCH=$(date +%s)` so `herdr_session_epoch` reflects the actual resume epoch timestamp instead of defaulting to `0`.
  - **Atomic Injection**: Safely forwards `NOW_EPOCH`, `TARGET_WORKSPACE`, and `ROLE` through environment variables into `atomic_dump_yaml`, preventing string-interpolation shell vulnerabilities.

### 2.2 Commit `57bc1b2`: Unbound Variable Initialization
- **Files Modified**:
  - `.agents/skills/multi-agent-mux-resume/scripts/update_yaml_resumed.sh`
- **Analysis**:
  - Added `AGENT=""` declaration alongside `SESSION_NAME` and `UUID` initialization.
  - Fixes `bash: AGENT: unbound variable` crash under `set -euo pipefail` when `update_yaml_resumed.sh` is called without `--agent`.

## 3. Protocol Alignment & Verification

- **Schema Validation**: Auto-created target entries strictly adhere to `atomic_dump_yaml`'s `_validate()` constraints (`name`, `status='running'`, `role`, `pane`, `herdr_server`, `start_command`, `attach_command`, `kill_command`).
- **Git Repository Status**: All commits are pushed and up to date with `origin/main`.
