diagnose_run

Everything needed to diagnose a failed run, in one call: the failing tests with fuller error messages, the feature's current Gherkin, the executed spec sources, artifact download links, and the log tail. It replaces the get_run → read_file → get_run_artifacts round trips an agent otherwise needs before it can fix anything.

}

A run that passed returns "verdict": "passed" with the summary and no failure context; a run still executing returns "verdict": "running" — wait for it first (wait_for_run).

Field	Notes
failures	Non-passed tests only, errors trimmed at 6,000 chars (vs 1,500 in get_run).
gherkin / featureStatus	The feature's current source — absent when the feature was deleted since the run.
specs	The executed spec files' stored content (first 5 files, 8,000 chars each; specsTruncated: true when capped).
artifacts	Same short-lived links as get_run_artifacts.

Errors

404 not_found	No such run in this project.
