Harness Engineering
Harness = the operating system for AI agents working on your project. Model is CPU, context window is RAM, harness is OS.
Core Principle
Start simple, add complexity only when needed. Every harness component encodes an assumption about what the model can't do alone. Pressure-test these assumptions — they expire as models improve. Build for deletion.
When This Skill Activates

| Empty/new project | → Full project setup (Section 1) |
| User frustrated with agent | → Diagnose & fix harness gaps (Section 7) |
| Existing project needs improvement | → Assess & incrementally improve |
| Explicit harness question | → Reference relevant sections |
