[aw] Release Changelog Generator produced no safe outputs

### Workflow Failure

**Workflow:** [Release Changelog Generator](https://github.com/github/copilot-sdk/blob/main/.github/workflows/release-changelog.md)
**Branch:** main
**Run:** https://github.com/github/copilot-sdk/actions/runs/34855078063

> [!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.):

````

> [!TIP]
>
> Stop reporting this workflow as a failure

.github/workflows/release-changelog.md と issue にリンクされた失敗した実行から始めます。gh-aw debug.md のガイダンスと agentic-workflows skill を読み、その後、エージェントが安全な出力を生成しなかった理由を追跡します。完了の条件は、workflow が期待される changelog 出力を生成するか、アクションが不要な場合に noop を明示的に呼び出すことです。
