 **Tracking Worker Output**: The campaign has knowledge of its workers (listed in the `workflows` field) and monitors their output directly. For each worker workflow:
 
-1. Query GitHub Actions API for recent workflow runs using the worker's `tracker-id` (e.g., `daily-file-diet`)
-2. Examine workflow run outputs and artifacts to discover issues created by the worker
-3. Ensure all issues created by campaign workers are added to the project board (if not already present)
-4. Update project board item statuses and fields as needed to reflect current state
-5. Report on overall campaign progress based on worker outputs and issue counts
+1. **Query GitHub Actions API for recent workflow runs** using the GitHub MCP server:
+   - Use `github-list_workflow_runs` with the worker's workflow file (e.g., `daily-file-diet.lock.yml`)
+   - Filter for recent completed runs (last 24-48 hours) to find worker activity
+
+2. **Extract issue URLs from workflow run artifacts**:
+   - Use `github-list_workflow_run_artifacts` to list artifacts from each workflow run
+   - Download the `agent-output` artifact which contains workflow outputs
+   - Parse the artifact to extract issue URLs created by safe-output actions
+   - Look for outputs like: `GH_AW_OUTPUT_CREATE_ISSUE_ISSUE_URL` in the run logs
+
+3. **Alternative: Use GitHub Issues search** as a fallback:
+   - Search for recently created issues with labels matching the worker's output patterns
+   - Filter by creation date (within the worker's run time window)
+   - Cross-reference with workflow run timestamps to confirm correlation
+
+4. **Add discovered issues to the project board**:
+   - Use `update-project` safe-output to add issue URLs to the project board
+   - Set appropriate status fields (e.g., "Todo", "In Progress", "Done")
+   - Preserve any existing project item metadata
+
+5. **Report on campaign progress**:
+   - Count total issues discovered from worker runs
+   - Track open vs closed issues
+   - Calculate progress percentage
+   - Highlight any issues that need attention

+Workers operate independently without knowledge of the campaign. The orchestrator discovers their work by monitoring workflow runs, parsing artifacts, and extracting issue URLs from workflow outputs.
 
 **Understanding Empty Boards**: If you find zero items on the project board, this is normal when a campaign is just starting or when all work has been completed. This is not an error condition - simply report the current state. Worker workflows will create issues as they discover work to be done, and the orchestrator will add them to the board on subsequent runs.
