+# NEW_FEAT — Document Query Tool
+
+## Summary
+Add a tool to retrieve documentation files based on scope, topic, and keyword.
+
+## Tool
+`get_docs(scope, topic, keyword)`
+
+### Parameters
+- **scope**: enum `organization | department | team | agent`
+- **topic**: enum `docs | notes | knowledge | rules | lessons | workflows`
+- **keyword**: string (supports regular expressions)
+
+## Behavior
+- Search matching files under `${openclaw dir}/yonexus/organizations/...` based on the given scope/topic.
+- `keyword` is applied to filenames (regex supported).
+- Output grouped by scope in the following format:
+```
+----ORG
+<file list>
+----DEPT
+<file list>
+----TEAM
+<file list>
+----AGENT
+<file list>
+```
+- If no match in a group, output the header with no files beneath.
+
+## Notes
+- Search should be read-only.
+- Pattern errors should return a structured error (invalid regex).
