Slack

Recommended setup

Arden currently supports Slack through workspace tokens. The desktop setup assistant makes the token path explicit and verifies it before saving.

You can also set tokens through environment/config:

export SLACK_BOT_TOKEN=xoxb-...
export SLACK_USER_TOKEN=xoxp-...

Or save the token in Settings → Integrations → Slack.

Tool	Description
`slack_search`	Search Slack messages
`slack_channel`	Read channel history
`slack_thread`	Read a thread
`slack_dm` / `slack_dms`	Read direct messages
`slack_file`	Read Slack file/image content
`slack_post_message`	Post a message (requires approval)
`slack_post_blocks`	Post block-kit content (requires approval)
`slack_user` / `slack_users`	Resolve Slack users

xoxb- bot tokens usually need the bot to be invited to private channels before it can read or post there.
xoxp- user tokens act as the installing user and should be treated as highly sensitive.
If verification fails, check the token prefix, workspace, revoked-token state, and Slack app scopes.

Arden does not ship a shared Slack OAuth app yet. The setup assistant is intentionally honest: token setup now, OAuth install later.
