[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/34950791499

> [!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/34950791499
````

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/34950791499`

> [!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 .github/workflows/issue-classification.md and the failed run linked in the issue. Read the referenced gh-aw debug.md and .github/skills/agentic-workflows/SKILL.md, then determine why the agent produced no safe outputs. Done means the workflow no longer reports this failure when it completes its classification task.
