description	Slack team communication platform. Use for team chat.

Slack

Slack is the OS of work. 2025 turns it into an Agentic OS where AI agents can read messages, summarize threads, and trigger workflow actions autonomously.

When to Use

• Corporate Comms: The standard for 99% of tech companies.
• Ops Triggers: "ChatOps" (deploy from Slack).
• Huddles: Quick voice/screen sharing.

Core Concepts

Block Kit

UI framework for building interactive messages and modals.

Workflow Builder

No-code automation ("When user joins channel, send DM").

Apps

Integrations (GitHub, Linear, Jira).

Best Practices (2025)

Do:

• Use Canvas: Store persistent info (team links) in a channel canvas.
• Use Huddles: Faster than Zoom for quick syncs.
• Use "Catch Up": The mobile swipe interface to clear unreads.

Don't:

• Don't use @channel: Unless the building is on fire.
