 `--audio` sends a voice message and supports only Opus audio files, for example `.opus` files or Ogg Opus (`.ogg`) files. For `mp3`, `wav`, or other non-Opus audio, either convert to `.opus` first and keep using `--audio`, or send the original file as an attachment with `--file`.

+# card.action.trigger
+
+> **Prerequisite:** Read [`../../lark-event/SKILL.md`](../../lark-event/SKILL.md) first for `event consume` essentials.
+
+Fires when a user interacts with an interactive card — button click, form submit, dropdown select,
+checkbox toggle, date/time pick, etc.
+
+## Setup (required)
+
+> **Console configuration required**: In the Feishu Developer Console, go to
+> **App → Events & Callbacks → Callback Configuration** (应用--事件与回调--回调配置) and enable it.
+> The consumer starts without errors even when not configured, but **no events will be received**.
+> There is no preflight check for this setting.
+
+After enabling, events are delivered over the existing WebSocket long connection — no additional
+URL configuration needed.
+
+## Scopes & auth
+
+| Scope | Required for |
+|---|---|
+| `im:message:readonly` | Auto-fetch `card_content` via message get API (covers both p2p and group messages) |
+
+Auth: `bot` only.
+
+## Output fields
+
+| Field | Type | Description |
+|---|---|---|
+| `type` | string | Always `card.action.trigger` |
+| `event_id` | string | Unique event ID; safe for deduplication |
+| `timestamp` | string (timestamp_ms) | Event delivery time (ms since epoch) |
+| `operator_id` | string (open_id) | Open ID of the user who interacted |
+| `message_id` | string (message_id) | Message ID of the card (`om_xxx`) |
+| `chat_id` | string (chat_id) | Chat ID (`oc_xxx`) |
+| `host` | string | `im_message` (chat card) or `im_top_notice` (top banner) |
+| `token` | string | Delayed-update token; valid 30 min, max 2 uses |
+| `action_tag` | string | Component type that was triggered (see decision table) |
+| `action_value` | string | Developer-defined value on the component; serialized to JSON string |
+| `action_name` | string | `name` attribute of the component |
+| `timezone` | string | User timezone, e.g. `Asia/Shanghai`; only populated for date/time picker interactions |
+| `form_value` | string (JSON) | All form field values as JSON string, keyed by component `name`; only present when a button inside a form container is clicked |
+| `input_value` | string | Input text; only for standalone `input` components (not inside a form) |
+| `option` | string | Selected value for standalone single-select: `select_static`, `select_person`, `overflow`, `date_picker`, `picker_time`, `picker_datetime` |
+| `options` | string | Comma-separated selected values for standalone multi-select: `multi_select_static`, `multi_select_person` |
+| `checked` | bool | Checkbox state for standalone `checker` elements |
+| `card_content` | string | Original card content (userDSL text format) from when the card was sent; auto-fetched via message get API at consume time; empty if `message_id` absent or fetch fails — skip if empty |
+
+## `card_content` — what it is and how to use it
+
+`card_content` is the `user_dsl` field extracted from the card message content, auto-fetched
+at event consume time. It represents the card's original definition — use it as the starting
+point to understand the current card structure and construct the updated card JSON.
+
+No extra API call is needed — the consumer fetches it automatically. If empty, skip — no fallback required.
+
+## action_tag decision table
+
+> **Form container rule**: when a component is inside a `form` container, its value appears in
+> `form_value[name]` instead of the standalone fields (`option`, `options`, `input_value`,
+> `checked`). There is no `form_submit` tag — form submission comes through as `button` with
+> `form_value` populated.
+
+| `action_tag` | Read field(s) | Notes |
+|---|---|---|
+| `button` | `action_value` (fromjson if object); `form_value` if inside a form | Most common; `form_value` non-empty = form submit |
+| `overflow` | `option` | Collapsible button group selection |
+| `select_static` | `option` (standalone) or `form_value[name]` (in form) | Single-select dropdown |
+| `multi_select_static` | `options` (standalone) or `form_value[name]` (in form) | Multi-select dropdown |
+| `select_person` | `option` — open_id of selected user | Single-select person |
+| `multi_select_person` | `options` — comma-separated open_ids | Multi-select person |
+| `input` | `input_value` (standalone) or `form_value[name]` (in form) | Text input |
+| `checker` | `checked` (standalone) or `form_value[name]` (in form) | Checkbox |
+| `date_picker` | `option` (date string) + `timezone` | e.g. `"2024-04-01 +0800"` |
+| `picker_time` | `option` (time string) + `timezone` | e.g. `"08:30 +0800"` |
+| `picker_datetime` | `option` (datetime string) + `timezone` | e.g. `"2024-04-29 07:07 +0800"` |
+| `select_img` | `option` (single) or `options` (multi) | Image picker |
+
+## Key constraints
+
+1. Token **valid 30 minutes**, **max 2 uses** — if update fails after exhaustion, inform the user
+2. Delayed-update API requires **complete new card JSON** — partial updates are not supported
+3. SDK auto-responds `{"code":200}` within 3 s — your update call can be sent any time within 30 min
+4. `card_content` is auto-populated — no extra API call needed; if empty, skip it
+
+## After starting the listener
+
+Once the listener is running, check whether your agent runtime supports background event
+monitoring (i.e. can receive and process stdout lines from a running subprocess while
+continuing to respond to the user). If it does, prompt the user:
+
+> "Card callback listener is now active. Do you want me to automatically handle card
+> interactions and update the card based on user actions?"
+
+Only enter the auto-update workflow below if the user confirms. If your runtime does not
+support background monitoring, inform the user that automatic card updates are not available
+and they will need to handle interactions manually.
+
+## Agent workflow
+
+When a `card.action.trigger` event arrives (**each stdout JSON line is one event — process it immediately**):
+
+```
+1. Read action fields to understand what the user did:
+   - action_tag: which component was triggered
+   - action_value / option / options / checked / input_value / form_value: what value was set
+
+2. Decide: does this interaction require a card update?
+   - e.g. button click with a business action → yes
+   - e.g. navigation / pagination → no (just record, no update needed)
+   - Not every callback requires a card update — decide based on business semantics
+   - Before updating, explicitly state what visual change the action requires. If you cannot articulate one, skip the update.
+
+3. If update is needed:
+   a. If card_content is empty: inform the user that the original card could not be fetched,
+      so it is not possible to determine whether an update is needed — do not guess
+   b. Determine the new card state based on the action
+   c. Use card_content as the structural basis to construct the updated card JSON
+   d. Detect card version: if card_content contains `"schema":"2.0"` or `"schema": "2.0"` it is Card 2.0; otherwise assume Card 1.0
+   e. For Card 1.0: include `"open_ids": ["<operator_id>"]` inside the `card` object, or the API returns code 300090
+   f. Call the delayed update API with the token and new card JSON
+
+4. If no update: end (the SDK has already acknowledged the callback)
+```
+
+## Updating the card
+
+```bash
+lark-cli api POST /open-apis/interactive/v1/card/update --as bot \
+  --data '{"token":"<token>","card":<new_card_json>}'
+```
+
+`--data` parameters:
+
+| Field | Required | Description |
+|---|---|---|
+| `token` | Yes | Delayed-update token from the event |
+| `card` | Yes | Complete new card JSON — construct based on `card_content` from the event, modified to reflect the new state |
+| `card.open_ids` | No | **Card 1.0 only.** Array of `open_id`s defining which users see the updated card. Must contain at least one open_id (e.g. the operator's); passing `[]` or omitting the key both cause "openid empty" (code 300090). |
+
+## Examples
+
+```bash
+# Stream all card interactions
+lark-cli event consume card.action.trigger --as bot
+
+# Grab one callback to inspect shape (debugging only — do not use in production workflows)
+lark-cli event consume card.action.trigger --as bot --max-events 1 --timeout 60s
+
+# Button clicks only (not form submit), with action value
+lark-cli event consume card.action.trigger --as bot \
+  --jq 'select(.action_tag == "button" and .form_value == "") | {op: .operator_id, val: (.action_value | fromjson?), token: .token}'
+
+# Form submits (button with form_value present)
+lark-cli event consume card.action.trigger --as bot \
+  --jq 'select(.action_tag == "button" and .form_value != "") | {op: .operator_id, form: (.form_value | fromjson), token: .token}'
+
+# Date picker interactions
+lark-cli event consume card.action.trigger --as bot \
+  --jq 'select(.action_tag == "date_picker") | {op: .operator_id, date: .option, tz: .timezone}'
+
+# Filter to one chat
+lark-cli event consume card.action.trigger --as bot \
+  --jq 'select(.chat_id == "oc_xxx")'
+```
+
+## Gotchas
+
+- **No `form_submit` tag**: form submission comes as `action_tag = "button"` with `form_value`
+  populated. Check `form_value != ""` to distinguish from a standalone button click.
+- **`action_value` type is developer-defined**: the original may be an object or a plain string.
+  Use `fromjson?` (with `?` to swallow errors) or check before parsing.
+- **Standalone vs form fields**: `input_value`, `option`, `options`, `checked` are only populated
+  for components **not** inside a form container. Inside a form, all values appear in `form_value`.
+- **WebSocket delivery**: no separate callback URL needed; uses the existing WS connection.
