 """Path-scoped IO tools for the skill-create agent.
 
 The skill-create agent runs with these capabilities:
-  * READ wiki structure       — ``list_wiki_dir``
-  * READ wiki markdown        — ``read_wiki_file_for_skill``
+  * READ wiki structure       — ``list_wiki_dir`` (delegates to
+    ``openkb.agent.tools.list_wiki_files``)
+  * READ wiki markdown        — ``read_wiki_file_for_skill`` (delegates to
+    ``openkb.agent.tools.read_wiki_file``)
   * READ PageIndex source pages — ``get_skill_page_content`` (delegates to
     ``openkb.agent.tools.get_wiki_page_content``)
   * READ wiki images          — ``read_skill_image`` (delegates to
     ``openkb.agent.tools.read_wiki_image``)
   * WRITE under skill root    — ``write_skill_file``
 
-The first four wrap the canonical wiki tools in ``openkb/agent/tools.py``
-so the skill agent traverses the wiki the same way the query agent does —
-no separate retrieval semantics, no second implementation to drift.
+The first four are thin wrappers around the canonical wiki tools in
+``openkb/agent/tools.py`` so the skill agent traverses the wiki the same
+way the query agent does — no separate retrieval semantics, no second
+implementation to drift.
 
 These helpers enforce write boundaries at the Python level — every write
 resolves its target path, then verifies it stays inside the skill root.
