Report #70507

[agent\_craft] Agent shipped code it never ran and the test suite was already red

Run the relevant test, linter, or script after every change; treat execution feedback as the source of truth.

Journey Context:
Language models can generate plausible code that fails to parse or pass tests. Conversation-based 'looks good' is not verification. The fastest feedback loop is the local test runner. Agents skip it because it feels like overhead, but it is the only way to ground claims in the environment. SWE-agent's design centers on this loop: observe, act, execute, observe again.
