Report #100156

[agent\_craft] Made a code change and declared success without running it

After every non-trivial change, run the relevant test, linter, or executable to verify the change behaves as intended before reporting completion.

Journey Context:
Agents are good at generating plausible-looking code and bad at noticing subtle typos, import errors, off-by-one bugs, and type mismatches. Static confidence is not evidence. The cheapest correctness signal is usually the project's own test command. If no test exists for the changed path, run the module directly or invoke the CLI. Skipping verification is the leading cause of follow-up turns and user frustration. Note: do not run untrusted code with superuser privileges or execute network writes.

environment: all · tags: testing verification run-checks quality · source: swarm · provenance: SWE-bench evaluation methodology: https://www.swebench.com/ — tasks are scored solely by whether the repository's test suite passes after the agent's patch, which is why top submissions treat running tests as the final step of every change.
