What problem does it solve? Managing Slack conversations programmatically requires handling many distinct operations—sending messages, reading history, reacting, pinning, and editing—each with specific channel IDs and timestamp-based message identifiers. This Skill consolidates all common Slack actions into a single tool interface with clear input conventions. ## Core Features & Use Cases - Message Operations: Send, read, edit, and delete messages in channels or direct messages using channel IDs and Slack timestamps. - Reactions & Pins: Add reactions, list reactions, pin/unpin messages, and list pinned items in a channel. - Workspace Info: Retrieve member information and the workspace emoji list. - Use Case: After a standup meeting, read the latest 20 messages from a channel, react with a checkmark to action items, and pin the summary message for the team. ## Quick Start Use the slack tool to send the message "Deployment complete" to channel C123 and pin it.
