131 Tests, 4 Layers: Why My AI Agents Get an Eval Harness First
1Key Takeaways
- Originally published on AIdeazz — cross-posted here with canonical link.
- My first production AI agent shipped with 131 tests in its evaluation harness.
- This wasn't a luxury; it was a non-negotiable step after a $0.03/run silent failure nearly cost me a client.
- I built the harness before writing new features, a decision driven by the fundamental limitations of traditional unit tests in multi-agent systems.
