These are agent-side tools (Slack Bot / Programmable / Bolt agents), not available in Copilot.
find_slack_thread and attach_session_to_slack_thread are side-effectful, so they’re only available when named explicitly in a Programmable Agent’s allowlist. See the Tools Reference and YAML Configuration.Capabilities
Requires the Slack integration. These tools are only available when your workspace has connected Slack and the Paradime bot is a member of the target channel. See Connecting Slack.
