# Harness — Multi-Agent Orchestration
Orchestrate complex tasks through Planning -> Generation -> Evaluation -> Retro.
Fresh sub-agents per checkpoint prevent drift. Retro accumulates learning across tasks.
## Recommended Workflow
```
Session 1 (Claude Code) → Brainstorm + Spec → Spec review with cross-model evaluator
↓ spec approved
Session 2 (Codex) → Execute checkpoints → Evaluate → E2E → Full-verify → PR → Retro
↕ Claude CLI as review-loop peer (cross-model quality gate)
```
- **Session 1**: Claude Code for interactive discovery — brainstorming + multi-turn Q&A to establish requirements. **After the user approves the brainstormed design, spec drafting and the Spec Evaluator review loop run autonomously** (agent-to-agent until consensus). See [references/planning-protocol.md](references/planning-protocol.md) "Post-Brainstorming Autonomy".
- **Session 2**: Codex for autonomous execution — implementation, evaluation, PR creation, retro. Claude CLI serves as cross-model reviewer via `review-loop`.
- Both hosts support both phases. The above is the **recommended** flow, not a hard constraint.
## Prerequisites
1. `superpowers` plugin installed (Claude Code): Generator preloads TDD, verification, debugging skills
2. Reviewer role definitions: `harness-convention-scout.md`, `harness-spec-evaluator.md`, `harness-generator.md`, `harness-evaluator.md`, `harness-retro.md` — ship with this plugin at `plugins/harness-engineering-skills/agents/`; user overrides may l
