| What makes it different | - Every recommended setting actually exists on your specific amp—no phantom controls or made-up channels
- Gear-aware AI that accounts for differences between amp types, not generic settings for all users
- Real-recording analysis and researched gear data, not AI hallucination
- Works on your existing gear—no need to own the same equipment as the original artist
| - Import-first approach: reads existing configs from all your tools and converges them before you write YAML
- No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
- Portable across tools: single harness.yaml travels with you to every machine and tool
- Open source and free: no cost beyond existing Claude subscription
- Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
