Fix slide-deck-maintainer: require explicit safe output tool calls

[Copilot]

The slide-deck-maintainer workflow completed successfully but generated a false failure because the agent never called any safe output tools (noop or create_pull_request).

Agent attempted to verify safe output tool availability via bash commands (npm --prefix /tmp/gh-aw/actions ls | grep safeoutputs), hit permission errors, and incorrectly concluded tools were unavailable. Safe output tools are MCP tools called via the tool interface, not bash commands.

Changes

Added Step 9: Report Your Actions (REQUIRED)

• Mandatory safe output tool call before completion
• noop tool example for no-change scenarios with structured completion details
• Explicit clarification that these are MCP tools, not bash commands

Renumbered Step 10: Create Pull Request

• Previously Step 9
• Clarified to call create_pull_request tool

Added Completion Checklist

• Replaced prose summary with actionable checklist
• Reinforces mandatory tool call requirement

Example

When no changes are needed, agent must call:

{
  "message": "Slide deck maintenance complete - no changes needed",
  "details": {
    "slides_reviewed": 49,
    "layout_issues_found": 0,
    "content_errors_found": 0,
    "sources_checked": ["code", "docs", "workflows"],
    "focus_mode": "${{ inputs.focus }}",
    "next_recommended_focus": "feature-deep-dive"
  }
}

This pattern prevents false failures in periodic maintenance workflows that complete without making code changes.

<issue_title>[agentics] Slide Deck Maintainer failed</issue_title>
<issue_description>### Workflow Failure

Workflow: Slide Deck Maintainer
Branch: main
Run URL: https://github.com/github/gh-aw/actions/runs/21954945211

⚠️ 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

Debug this workflow failure using the agentic-workflows agent:

Pull request overview

Updates the slide-deck-maintainer workflow instructions to require an explicit safe output tool call (e.g., noop or create_pull_request) to prevent false “no safe outputs” failures.

Changes:

• Added a required “Report Your Actions” step with noop guidance for no-change runs and clarification that safe outputs are MCP tools (not bash-invoked).
• Renumbered the PR creation step and clarified calling create_pull_request.
• Replaced the prose summary with an actionable completion checklist emphasizing the required tool call.

The noop example JSON hard-codes values like slides_reviewed: 49 and zeros, which may be copied verbatim and produce misleading run metadata. Consider using placeholders (e.g., <number> / <string>), or explicitly label these as example values and instruct the agent to replace them with actual counts from the current run.
