Signature checks
Slack request signing can be verified before the payload reaches the agent loop.
Slack AI · gateway adapter
A Slack AI agent should not bypass governance.
Muster's Slack adapter maps Slack events into the shared gateway envelope, verifies signing secrets when configured, requires sender pairing, and records memory and token receipts for every run.
Slack setup path
Bot token, signing secret, pairing, then governed replies.
$ muster gateway init $ muster channels setup slack $ muster gateway start --port 7460 $ muster pairing approve <code>
Pairing required
Unknown senders receive a pairing challenge instead of direct agent access.
Token ledger
Slack turns are still normal Muster runs with usage and replay-waste visibility.
Tool policy
Commands and MCP tools remain behind explicit policy and setup checks.
Draft streaming
The gateway contains Slack draft posting and update support for smoother channel replies.
