Slack Integration

Slack Integration skill connects your Claude agent to Slack's Web API, enabling rich workspace automation for business communication. Post messages to any channel, send direct messages to users, reply in threads, add emoji reactions, update existing messages, and upload files — all with full Block Kit formatting support for interactive and visually structured messages.

Channel operations include creating and archiving channels, setting topics and descriptions, inviting members, and listing workspace channels programmatically. User lookups enable resolving names to IDs and vice versa, essential for building mention-aware automations. The skill reads channel history with pagination for analysis and audit workflows.

Business automation patterns: post a formatted daily standup prompt to an engineering channel each morning, relay CI/CD pipeline results from GitHub Actions into a #deployments channel, summarize customer feedback submitted via a form into a #product-feedback digest, or alert #on-call when a monitoring metric crosses a threshold. Slash command handling lets you build interactive Slack commands that trigger agent workflows.

Requires a Slack App with appropriate OAuth scopes — the skill's documentation lists the minimum required scopes for each feature group, helping you follow the principle of least privilege. Supports both Slack Free and paid workspace tiers. The most popular enterprise communication skill, trusted by DevOps teams, customer support operations, and product managers.
