# Harness — Generator + Verifier Pipeline Launches a two-agent development harness based on Anthropic's engineering pattern for long-running applications. The Generator (Opus) builds features sprint-by-sprint while the Verifier (Sonnet) independently tests and grades the output with hard thresholds. ## Usage ``` /harness Build a task management app with drag-and-drop, real-time sync, and dark mode /harness --sprints 5 Build a DAW with multi-track audio editing /harness --project-path /path/to/project Continue building from existing codebase ``` ## Arguments - First argument: Natural language description of what to build (required) - `--project-path PATH`: Project directory (default: current working directory) - `--sprints N`: Target number of sprints (default: 3) - `--app-url URL`: URL of running app for browser testing (Verifier will start the app if not provided) ## How It Works ### Step 1: Initialize Harness Directory Create `.harness/` in the project root: ```bash mkdir -p .harness/sprints ``` Write `.harness/roadmap.md` from the user's task description — break it into sprint-sized features. Write `.harness/decision-log.md` with initial setup notes. ### Step 2: Spawn Generator Agent ``` Agent( name: "generator", model: opus, prompt: <read ~/.claude/agents/harness/generator.md, inject PROJECT_PATH and roadmap>, run_in_background: true ) ``` The Generator reads the roadmap, proposes its first sprint contract, and begins implementing. ### Step 3: Spawn V
