Research direction

Start with the linked failed run and inspect the Install GitHub Copilot CLI step, then review the workflow source at .github/workflows/large-payload-tester.md and its gateway or setup logs. Identify why agent startup failed; done means the workflow starts the agent successfully and completes the task on a rerun.

Next step

Review the failure details below for a targeted fix, or assign this issue to a coding agent to investigate.

Failure details
Runtime evidence

[!WARNING]
Task Could Not Be Completed: The workflow recorded a report_incomplete signal: the task was not completed or completion could not be confirmed.

Error details: 
Failure classification: agent_startup_failure
Agent execution state: not_started
The runtime recorded that agent execution never started. Inspect the failed startup step and gateway/setup logs in the linked run; missing safe outputs are downstream, not evidence that the agent omitted a terminal output.

A comment or other safe output does not confirm that the requested task was completed. Only inferred runtime status and error codes are reported; agent text is excluded.

Failure Diagnostics

Agent job: agent
Agent job conclusion: failure
Failing step: Install GitHub Copilot CLI

No additional engine error was captured. Check the reported failure signals and linked run for details.

Only runtime metadata is shown; agent-generated text is excluded.

Copy a debugging prompt

Paste this into your coding agent:

Debug the agentic workflow "large-payload-tester" failure.
Follow https://raw.githubusercontent.com/github/gh-aw/main/debug.md
Failed run: https://github.com/github/gh-aw-mcpg/actions/runs/40026131371

If the repository includes the agentic-workflows skill, load it before investigating.

Manage failure notifications

To stop creating failure issues for this workflow, set this in its frontmatter and recompile:

safe-outputs:
  report-failure-as-issue: false

This only disables issue reporting; it does not fix the failure.
