description	Configure SlackApp or SlackLogin with /connect, then resolve Slack users/channels and search/read Slack messages through the internal CLI.

Use /connect slack-app <connection> or /connect slack-login <connection> when the user needs Slack connector setup, account setup, or auth repair. That flow uses AskUserQuestion for method choices and secrets.

Use Bash to run the Slack internal CLI only after auth exists, when the user needs Slack id lookup or message search/read workflows. Run Slack lookup commands as slack ... inside Bash.

Target: $target

Connection/account selection:

Slack has two first-party connector templates:

• slack-app: a Slack app connection with bot token and app-level token. Use it for app installs and bot-token channel actions.
• slack-login: a Slack workspace account connection from an OAuth token or browser session. Use it for local account operations and local app imports.

Slack workflow subscriptions and agent proxy mode are not implemented yet for these first-party templates. Do not create Slack workflows that rely on inbound Slack events until a typed Slack subscribe runtime exists.

The default connection slug is slack-app for configure-app, and slack-login for all login/import/lookup commands. When the user has multiple workspaces or accounts, use a distinct kebab-case connection slug and pass it to every Slack CLI command with --connection or --account.

slack --connection work-login search-conversations "deploys"
slack --connection work-login search-users "Tony"

After /connect auth completes, the auth tool automatically registers the connection with either connector_slug="slack-app" or connector_slug="slack-login". Use the same connection slug in ConnectorActionDraft for sends and ConnectorAct for non-send actions.

Lookup workflow:

When the user names a Slack channel, group DM, DM, or person, resolve the stable Slack id before acting. Do not send to an ambiguous display name, #channel name, or @handle directly.

slack --connection work-login search-conversations "deploys"
slack --connection work-login search-users "Tony"

Use returned conversation id values such as C..., G..., or D... as send targets. Use returned user id values such as U... as send targets when the task is a DM; Puffer opens the Slack DM before sending.

Message read and search workflow:

Use read-messages when you already have a channel id and optionally a thread timestamp. Use search-messages when the user asks to find text across Slack with Slack search syntax.

slack --connection work-login read-messages --channel C123 --limit 20
slack --connection work-login read-messages --channel C123 --thread-ts 1700000000.000100
slack --connection work-login search-messages "karen in:deploys" --limit 20

Connector action workflow:

Use ConnectorActionDraft for outbound Slack messages so the human can review the exact recipient and content before sending. Pass to or channel, plus message or caption. To reply in a thread, pass thread_ts or reply_to with the Slack timestamp. To send files, include media, file, files, or path with local file paths. Captions are sent as Slack upload comments. Use ConnectorAct only for non-send side effects such as reactions.

Use Slack reaction actions on connector targets after reading/searching messages for the exact channel and ts.
