+# Affordance
+
+Per-command usage guidance for the CLI, authored as one markdown file per domain
+(`<service>.md`). It is surfaced in `lark-cli <command> --help` and in the
+`schema` output, and read directly at runtime (lazy, cached) — there is no build
+step. Maintain these files alongside `skills/` and `shortcuts/`.
+
+## Format
+
+A small, fixed markdown subset; each file describes one domain:
+
+    # <domain>            optional `> skill: <name>` applies to every command below
+    ## <command>          the command as typed, minus `lark-cli <domain>`
+    <lead paragraph>      when to use this command
+    ### Avoid when        when not to use it / which command to use instead
+    ### Prerequisites     what you must have first (e.g. an id, and where it comes from)
+    ### Tips              gotchas and constraints
+    ### Examples          **description** lines, each followed by a fenced command
+    ### <other heading>   a custom section; flows through verbatim
+
+Reference another command with `[[command]]` — it renders as `command` in help.
+Under `Avoid when` it means "use that one instead"; under `Prerequisites`
+("… from [[command]]") it means "get the input there first".
+
+## Example
+
+    ## messages get
+    Fetch the full content of a single message by id.
+
+    ### Avoid when
+    - Reading several at once → use [[messages batch_get]]
+
+    ### Prerequisites
+    - message_id from [[messages list]]
+
+    ### Examples
+
+    **Fetch one message**
+    ```bash
+    lark-cli mail user_mailbox.messages get --message-id "<id>"
+    ```
+
+## Notes
+
+- Write plain prose; the only convention is wrapping command references in `[[ ]]`.
+- Keep it concise and high-signal — don't restate field/flag names, id types, or
+  anything the schema and flags already show; the agent infers the rest.
+- Command-form headings resolve to method ids via the registry, so plural resource
+  names (`messages`) map to the singular method id (`message`) automatically.

+## user_profiles batch_query
+Bulk-fetch personal status and signature for user ids you already have.
+
+### Avoid when
+- Need more than status/signature (name, dept, email), or don't have the open_id yet → use [[+search-user]]
+
+### Tips
+- Off by default — set include_personal_status / include_description to true under query_option
+- ids in user_ids must match --user-id-type (default open_id)
+
+### Examples
+
+**Bulk-query status and signature**
+```bash
+lark-cli contact user_profiles batch_query --data '{"user_ids":["ou_3a8b****6a7b"],"query_option":{"include_personal_status":true,"include_description":true}}'
