Slack

• You want your agent to acknowledge tasks by reacting to Slack messages (e.g. ✅ when a task is done).
• You need to send or update messages in channels or DMs programmatically, such as posting status updates or summaries.
• You want to pin important decisions or reference messages so the team can find them later.
• You need to read recent channel history or look up a team member's profile as part of an automated workflow.

• You need real-time event listening (webhooks, socket-mode events) — this skill only performs discrete actions, it does not subscribe to incoming events.
• You need to manage workspace-level administration (creating channels, managing users, setting permissions) — those actions are not included.

Send new messages to any channel or DM, edit existing messages, delete messages, and read recent message history — all with straightforward JSON action calls.

Add emoji reactions to any message using Unicode characters or :name: syntax, and list all existing reactions on a message. Useful for signaling task completion or approval.

Pin or unpin messages in any channel and retrieve the current list of pinned items. Ideal for surfacing key decisions or recurring reference material.

Fetch profile details for any workspace member by user ID, enabling your agent to personalize messages or route tasks to the right person.

Retrieve all custom emoji available in the workspace, so your agent can use workspace-specific reactions accurately.

When a task tracked in another system is marked complete, the agent reacts to the original Slack request message with ✅, giving the requester instant visual confirmation without sending a new message.

An agent composes and posts a daily or weekly summary to a team channel, then pins the message so it stays visible at the top of the channel for reference throughout the week.

After posting a report or announcement, the agent detects an error and uses editMessage to silently correct the content in place, avoiding a noisy follow-up post.

The agent looks up a team member's profile via memberInfo to confirm their display name or timezone, then sends them a DM with an incident alert targeted to their user ID.
