When an agent edits its own instructions, skills, or triggers during a chat, the changes are listed above the chat input and open with a click.
Auto Message Steering (Experimental)
Messages you send while an agent is working are now steered or queued for you, so a correction lands right away and a follow-up waits until the agent finishes.
SharePoint in Brain
Sync a SharePoint site into Brain, with each document visible only to the people who can open it in SharePoint.
Learn morePlatform Improvements
- Message an agent from Slack's agent panel and it knows which channel, thread, or canvas you have open, so "summarize this" needs no link.
- Compute credits in the chat credit breakdown now update as the agent works instead of landing when the run ends.
- Finished agent steps show how long the agent worked on them.
- Tasks filters now sit in a bar above the table, the header stays pinned as you scroll, and you can choose which columns show.
- Artifact links now use your organization's custom domain by default if configured.
- Create Brain sources and upload files to them from the API, or keep a folder synced into Brain with gumloop brain sync in the CLI. Read more here: https://docs.gumloop.com/cli/brain
MCP Improvements
- GitHub: Agents can now create, view, and merge stacked pull requests.
- Jira: Agents can now restrict a comment to a role or group instead of everyone on the issue.
- Zendesk: Creating a ticket with only a requester email no longer fails, and agents can name the requester.
Bug Fixes
- Fixed replies in a Slack thread a teammate started failing with a permission error for people who can use the agent.
- Fixed connector calls failing about an hour into long agent runs.
- Fixed the Slack progress card still saying Working on next step after the agent posted its final reply.
- Fixed files an agent shares in Slack being posted as Gumloop instead of the agent.
- Fixed the Slack plan block collapsing every time it updated.
