[aw] Issue Classification Agent produced no safe outputs

### Workflow Failure

**Workflow:** [Issue Classification Agent](https://github.com/github/copilot-sdk/blob/main/.github/workflows/issue-classification.md)
**Branch:** main
**Run:** https://github.com/github/copilot-sdk/actions/runs/34364189409

> [!WARNING]
> **No Safe Outputs Generated**: The agent job succeeded but did not produce any safe outputs.

This typically indicates:
- The safe output server failed to run
- The prompt failed to generate any meaningful result
- The agent should have called `noop` to explicitly indicate no action was taken

### Action Required

**Assign this issue to an agent** to debug and fix the issue.

Debug with any coding agent

Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.):

````
Debug the agentic workflow failure using https://raw.githubusercontent.com/github/gh-aw/main/debug.md

The failed workflow run is at https://github.com/github/copilot-sdk/actions/runs/34364189409
````

Manually invoke the agent

Debug this workflow failure using your favorite Agent CLI and the `agentic-workflows` prompt.

- Start your agent
- Load the `agentic-workflows` skill from `.github/skills/agentic-workflows/SKILL.md` or
- Type `debug the agentic workflow issue-classification failure in https://github.com/github/copilot-sdk/actions/runs/34364189409`

> [!TIP]
>
> Stop reporting this workflow as a failure
>
> To stop a workflow from creating failure issues, set `report-failure-as-issue: false` in its frontmatter:
> ```yaml
> safe-outputs:
> report-failure-as-issue: false
> ```

Start with the failed run linked in the issue and the workflow description in .github/workflows/issue-classification.md. Read .github/skills/agentic-workflows/SKILL.md for the debugging process, then determine why the run produced no safe outputs. Done means the workflow either generates an appropriate safe output or explicitly calls noop without reporting this failure.
