   - Final fix: switched `append_log` to use n8n workflow static data (`$getWorkflowStaticData('global')`) under key `actionLog`, capped to the latest 200 entries.
   - Verified persisted state via the n8n API: `staticData.global.actionLog` contains the live test record for request `live-log-003`.
   - Conclusion: for small recent operational breadcrumbs, workflow static data is the right sink here; MinIO is better reserved for later archival/rotation/export use cases rather than tiny per-event appends.
+- Added action `get_logs` to the live `openclaw-action` workflow and local `n8n-webhook` skill.
+  - `get_logs` reads from workflow static data key `actionLog`
+  - default limit `20`, clamped to `1..50`, newest-first
+  - verified live with request `live-getlogs-001` returning the seed record from `live-log-004`
+- Re-verified the three live actions together after the update:
+  - `append_log` → success
+  - `get_logs` → success
+  - `notify` → success
+- Refreshed packaged skill artifact again at `/tmp/n8n-skill-dist/n8n-webhook.skill`.
