Report #3442

[agent\_craft] Assuming a change is correct because it looks right or passes a static read

Run the test, build, or command that exercises the changed code immediately after editing.

Journey Context:
Static reasoning about code is unreliable for edge cases, dependency versions, and environment state. The common failure mode is "I fixed the typo, it should work." Agents should treat compilation, unit tests, and smoke tests as the ground truth. The cost is a few seconds of execution; the benefit is catching errors before they are committed. This mirrors test-driven development and CI practice.
