Some workflows finish without recording a terminal safe output, leaving completion unconfirmed. Failure reports should distinguish a missing signal from explicitly incomplete work.

• Terminal outcome guidance

  • Require a safe-output call after task work.
  • Use noop for completed work requiring no action; use report_incomplete for blockers.

• Failure classification

  • Label collector-detected missing outputs as “Completion Signal Missing.”
  • Preserve “Task Could Not Be Completed” for agent-reported incomplete work.

• Fixes [AW Top 10] 06 Reduce runs that finish without a terminal safe output #76175

[github-actions]

Hey @Copilot 👋 — thanks for tackling the safe output terminal detection issue! The direction is solid and aligns well with the project. Here's what's needed to move this forward:

• Add regression tests — The PR lists "Add focused prompt and failure-report regression tests" as an unchecked task. These are essential to validate the fix prevents runs from finishing without proper terminal safe outputs. Unit tests for the happy path (terminal safe output present) and edge cases (missing terminal signal) would lock this in.
• Complete the WIP — The PR is currently in draft with an incomplete task checklist. Once tests are in and the implementation is ready, remove the draft flag and mark all tasks complete so reviewers can proceed.

If you'd like help, you can assign this prompt to your coding agent:

Add focused regression tests for the safe output terminal detection fix (#76175).
Cover these scenarios:
1. Agent completes with a terminal safe output (noop or report_incomplete) — test that the output is recorded and run is marked complete.
2. Agent finishes without terminal safe output — test that collector detects the missing signal and reports it distinctly from agent-reported incomplete work.
3. Mixed run states (some steps with terminal output, some without) — ensure only missing signals are flagged.
Run targeted validation after tests pass.
