 - **Read messages**: Retrieve recent messages from channels or DMs, with filtering by time range
 - **Manage channels and users**: List channels, members, and users in your Slack workspace
 - **Download files**: Retrieve files shared in Slack channels for processing within a workflow
+- **Build Slack agents**: Manage Agent Sessions, stream replies, handle stop/title/context events, and configure Agent View actions and suggested prompts for custom bots
 
 In Sim, the Slack integration enables your agents to programmatically interact with Slack as part of their workflows. This allows for automation scenarios such as sending notifications with dynamic updates, managing conversational flows with editable status messages, acknowledging important messages with reactions, and maintaining clean channels by removing outdated bot messages. The integration can also be used in trigger mode to start a workflow when a message is sent to a channel.

 ## Usage Instructions
 
-Integrate Slack into the workflow. Can send, update, and delete messages, send ephemeral messages visible only to a specific user, open/update/push modal views, publish Home tab views, create canvases, read messages, and add or remove reactions. Requires Bot Token instead of OAuth in advanced mode. Can be used in trigger mode to trigger a workflow when a message is sent to a channel.
+Integrate Slack messaging and administration into a workflow. Custom Slack bots can manage Agent Sessions, stream incremental Markdown or structured chunks, react to Agent Session events, and configure Agent View suggested prompts. Standard messaging and management operations support both the Sim app and custom bot credentials.
