[AW Top 10] 01 Improve diagnostics for missing terminal outputs #66485

Description

@github-actions

Priority 1/10 | 40 source issues | Impact 4/5 | Confidence 3/5 | Effort 3/5

One assignment, one coherent fix

Many workflows end with no terminal safe output or an engine driver failure, and the failure issues carry only a generic message. Maintainers cannot tell a driver crash from a prompt problem or an engine outage.

Implementation scope

Capture the driver exit code, the last engine error and the retry history in the failure issue, and classify the cause as engine outage, request rejection or prompt exhaustion. Deduplicate issues for the same workflow and cause.

Done when

  • The failure issue includes the exit code, a classified cause and the last engine error.
  • Repeated failures of one workflow with one cause update a single issue.

Why now

About forty issues share the symptom across engines, which makes triage costly. This change improves diagnosis rather than fixing each underlying cause.

No corroborating AW discussion; evidence comes from the source issues.

Unchanged AW sources close only after this summary is completed. Newer source activity and not-planned retirement do not trigger source closure. Assigned summaries are frozen; unassign to allow reclustering.

    Driver message may contain secrets and should not be part of the issue. Generic error type is ok.
