Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.

+summary: "Reaction tool semantics across all supported channels"
+read_when:
+  - Working on reactions in any channel
+  - Understanding how emoji reactions differ across platforms
+title: "Reactions"
+---
+
+The agent adds and removes emoji reactions with the `message` tool's `react`
+action. Behavior varies by channel.
+
+## How it works
+
+```json
+{
+  "action": "react",
+  "messageId": "msg-123",
+  "emoji": "thumbsup"
+}
+```
+
+- `emoji` is required when adding a reaction.
+- Set `emoji` to an empty string (`""`) to remove the bot's reaction(s) on
+  channels that support it.
+- Set `remove: true` to remove one specific emoji (requires non-empty
+  `emoji`).
+- On channels with status reactions, `trackToolCalls: true` on a reaction lets
+  the runtime reuse that reacted message for subsequent tool-progress
+  reactions during the same turn.
+
+## Channel behavior
+
+<AccordionGroup>
+  <Accordion title="Discord and Slack">
+    - Empty `emoji` removes all of the bot's reactions on the message.
+    - `remove: true` removes just the specified emoji.
+
+  </Accordion>
+
+  <Accordion title="Google Chat">
+    - Empty `emoji` (or `remove: true`) removes the bot's own reactions on the message, filtered to `emoji` when set.
+    - `remove: true` removes just the specified emoji.
+
+  </Accordion>
+
+  <Accordion title="Nextcloud Talk">
+    - Adding reactions only: `emoji` is required and must be non-empty.
+    - Reaction removal is not wired to a delete call yet; `remove: true` is rejected with an explicit error instead of silently no-oping.
+    - Requires the Talk bot registered with the `reaction` feature (see [Nextcloud Talk channel docs](/channels/nextcloud-talk)).
+
+  </Accordion>
+
+  <Accordion title="Telegram">
+    - Empty `emoji` removes the bot's reactions.
+    - `remove: true` also removes reactions but still requires a non-empty `emoji` for tool validation.
+
+  </Accordion>
+
+  <Accordion title="WhatsApp">
+    - Empty `emoji` removes the bot reaction.
+    - `remove: true` maps to empty emoji internally (still requires `emoji` in the tool call).
+    - WhatsApp has one bot reaction slot per message; sending a new reaction replaces it rather than stacking multiple emoji.
+
+  </Accordion>
+
+  <Accordion title="Zalo Personal (zalouser)">
+    - Requires non-empty `emoji` for both add and remove.
+    - `remove: true` removes that specific emoji reaction.
+
+  </Accordion>
+
+  <Accordion title="Feishu/Lark">
+    - Uses the same `react` action as other channels (add/remove/list via message reaction IDs), not a separate tool.
+    - Adding requires non-empty `emoji` (mapped to a Feishu `emoji_type`, e.g. `SMILE`, `THUMBSUP`, `HEART`).
+    - `remove: true` requires non-empty `emoji` and removes the bot's own reaction matching that emoji type.
+    - Empty `emoji` with `clearAll: true` removes all of the bot's reactions on the message.
+
+  </Accordion>
+
+  <Accordion title="Signal">
+    - Inbound reaction notifications are controlled by `channels.signal.reactionNotifications`: `"off"` disables them, `"own"` (default) emits events when users react to bot messages, `"all"` emits events for all reactions, and `"allowlist"` emits events only for senders in `channels.signal.reactionAllowlist`.
+
+  </Accordion>
+
+  <Accordion title="iMessage">
+    - Outbound reactions are iMessage tapbacks (`love`, `like`, `dislike`, `laugh`, `emphasize`, and `question`); `emoji` must map to one of these kinds to add a reaction.
+    - `remove: true` without a recognized tapback kind removes all tapback kinds; with a recognized kind it removes just that one.
+
+  </Accordion>
+</AccordionGroup>
+
+## Reaction level
+
+Per-channel `reactionLevel` throttles how often the agent sends its own
+reactions. Values: `off`, `ack`, `minimal`, or `extensive`.
+
+- [Telegram reaction notifications](/channels/telegram#feature-reference) - `channels.telegram.reactionLevel` (default `minimal`)
+- [WhatsApp reaction level](/channels/whatsapp#reaction-level) - `channels.whatsapp.reactionLevel` (default `minimal`)
+- [Signal reactions](/channels/signal#reactions-message-tool) - `channels.signal.reactionLevel` (default `minimal`)
+
+## Related
