Report #132

[agent\_craft] Agent declares success but the change is broken because it only 'looks correct'

Always pair implementation with an executable check: run tests, build, lint, or a script that exits non-zero on failure. Ask the agent to run the check and iterate until it passes before reporting done.

Journey Context:
'Looks done' is the weakest signal. Without a pass/fail check, the agent and the human become the verification loop, which misses edge cases. The fix is to close the loop with the machine: a test, a compiler, a type checker, or a diff against fixtures. Provide the check in the same prompt as the task so the agent knows what 'done' means and can self-correct. This is test-driven practice adapted for agents.
