+    You modified files in `.deepwork/jobs/deepwork_jobs/` or `.deepwork/jobs/deepwork_policy/`.
+
+    **These are installed copies, NOT the source of truth!**
+
+    Standard jobs (deepwork_jobs, deepwork_policy) must be edited in their source location:
+    - Source: `src/deepwork/standard_jobs/[job_name]/`
+    - Installed copy: `.deepwork/jobs/[job_name]/` (DO NOT edit directly)
+
+    **Required action:**
+    1. Revert your changes to `.deepwork/jobs/deepwork_*/`
+    2. Make the same changes in `src/deepwork/standard_jobs/[job_name]/`
+    3. Run `deepwork install --platform claude` to sync changes
+    4. Verify the changes propagated correctly
