# Slack

> Post workflow results to Slack channels.

## What this connection enables

The **Archiver Agent** uses Slack as a delivery destination. When a workflow completes, results can be posted to a Slack channel of your choice — useful for surfacing summaries or analysis without switching context.

## Connect it

From **Apps**, click **Connect Slack**. A popup runs OAuth and the card flips to **Connected** once Composio confirms. See [Connections](https://docs.celerflow.ai/concepts/connections.md) for scope, stale-account handling, and polling behavior.

## Scopes and permissions

Slack access is scoped to posting messages to channels the OAuth user can see. The integration does not read message history.

## Known limitations

Slack delivery works end-to-end through the Archiver Agent. What's still being polished is the in-chat experience: after you connect Slack mid-build, the Planner doesn't yet auto-resume on the OAuth-completion signal the way Gmail and Notion do. See [Roadmap](https://docs.celerflow.ai/platform/roadmap.md).
