+
+# Feishu Wiki Tool
+
+Single tool `feishu_wiki` for knowledge base operations.
+
+## Token Extraction
+
+From URL `https://xxx.feishu.cn/wiki/ABC123def` → `token` = `ABC123def`
+
+## Actions
+
+### List Knowledge Spaces
+
+```json
+{ "action": "spaces" }
+```
+
+Returns all accessible wiki spaces.
+
+### List Nodes
+
+```json
+{ "action": "nodes", "space_id": "7xxx" }
+```
+
+With parent:
+
+```json
+{ "action": "nodes", "space_id": "7xxx", "parent_node_token": "wikcnXXX" }
+```
+
+### Get Node Details
+
+```json
+{ "action": "get", "token": "ABC123def" }
+```
+
+Returns: `node_token`, `obj_token`, `obj_type`, etc. Use `obj_token` with `feishu_doc` to read/write the document.
+
+### Create Node
+
+```json
+{ "action": "create", "space_id": "7xxx", "title": "New Page" }
+```
+
+With type and parent:
+
+```json
+{
+  "action": "create",
+  "space_id": "7xxx",
+  "title": "Sheet",
+  "obj_type": "sheet",
+  "parent_node_token": "wikcnXXX"
+}
+```
+
+`obj_type`: `docx` (default), `sheet`, `bitable`, `mindnote`, `file`, `doc`, `slides`
+
+### Move Node
+
+```json
+{ "action": "move", "space_id": "7xxx", "node_token": "wikcnXXX" }
+```
+
+To different location:
+
+```json
+{
+  "action": "move",
+  "space_id": "7xxx",
+  "node_token": "wikcnXXX",
+  "target_space_id": "7yyy",
+  "target_parent_token": "wikcnYYY"
+}
+```
+
+### Rename Node
+
+```json
+{ "action": "rename", "space_id": "7xxx", "node_token": "wikcnXXX", "title": "New Title" }
+```
+
+## Wiki-Doc Workflow
+
+To edit a wiki page:
+
+1. Get node: `{ "action": "get", "token": "wiki_token" }` → returns `obj_token`
+2. Read doc: `feishu_doc { "action": "read", "doc_token": "obj_token" }`
+3. Write doc: `feishu_doc { "action": "write", "doc_token": "obj_token", "content": "..." }`
+
+## Configuration
+
+```yaml
+channels:
+  feishu:
+    tools:
+      wiki: true # default: true
+      doc: true # required - wiki content uses feishu_doc
+```
+
+**Dependency:** This tool requires `feishu_doc` to be enabled. Wiki pages are documents - use `feishu_wiki` to navigate, then `feishu_doc` to read/edit content.
+
+## Permissions
+
+Required: `wiki:wiki` or `wiki:wiki:readonly`
