The harness-engineering mindset — Agent equals Model plus Harness (step 8/8) · harness engineering

Checkpoint

One last thing before we move on. pass this to mark the lesson done, or skip and keep moving. hop to the next when you're ready.

Final drill for the mindset lesson. Write triage_harnesses(harnesses) that scores five harness configurations and returns a dict:

scores: dict mapping each harness name → its 0-100 score (insertion order preserved)
weakest: the name of the harness MOST likely to fail first (lowest score). On a tie, return the FIRST one in input order.

Reuse the six-piece scoring from the previous drill:

Each present piece (config, tools, infra, orchestration, hooks, observability) adds 16.
All six present → 100.

Five harnesses run for you. Expected output:

scores: {'claude-code-pro': 100, 'cursor-default': 64, 'aider-basic': 32, 'raw-anthropic': 16, 'inhouse-wrapper': 64}
weakest: raw-anthropic
