slack is an OpenClaw tool skill for Slack send, read, edit, delete, react, pin, and member actions.
About
The slack skill documents OpenClaw slack tool actions for channel messaging and member lookup. Inputs use channelId, messageId as Slack timestamps, to as channel or user targets, and emoji as Unicode or colon names. Actions include sendMessage, readMessages with limit, react, reactions list, editMessage, deleteMessage, pinMessage, unpinMessage, listPins, memberInfo, and emojiList, each as JSON action payloads. The agent should reuse channelId and message IDs from context when present rather than fuzzy name resolution. Safety rules require confirming destructive deletes when context is unclear, keeping outbound messages short, avoiding Markdown tables in Slack, and preferring thread or message IDs over fuzzy channel names. Configuration requires channels.slack in OpenClaw metadata. Teams invoke it when agents need to post updates, read channel history, add reactions, or manage pins in Slack workspaces connected to Clawdis.

- Reuse channelId and messageId timestamps from context when available.
