File deletion for agents; OAuth client-secret support; template onboarding

June 29 - July 3, 2026

New features

• The Access Profiles dialog in chat now includes a Create an access profile link that opens the sandboxes create flow, so you can add a profile when a workspace has none configured instead of hitting a dead end.

• Fleet agents can now delete files from their memory and skills using the new delete tool, including files in linked workspace skills. Core agent files and read-only system skills remain protected.

• Fleet now completes OAuth for MCP servers whose authorization server requires client-secret authentication at the token endpoint, so connecting these servers no longer fails after the consent step.

• First-time Fleet users now see a streamlined welcome modal with two clear paths — describe an agent to build with AI (starting from a prompt in Chat) or start from a curated template — replacing the previous multi-step setup wizard.

• Creating an agent from a Fleet template now skips the setup wizard and opens the agent editor with the template onboarding card.

• Fleet now sends the MCP protocol version a server negotiates during the handshake, both when loading tools and when the agent calls them, so MCP servers that require a newer version no longer return zero tools or fail tool calls.

• Fleet agents receive the day of week alongside the current date (for example “Monday, June 29th 2026”), so scheduling and date reasoning no longer relies on the model inferring the weekday from the ISO date.

• File edits in Fleet agent chat now render as syntax-highlighted, line-by-line diffs, making changes easier to review.

• When you connect a custom Slack bot to a Fleet agent, Fleet sends the installer a direct message with quick setup tips, including how to add the bot to channels and mention it with @.

• Fleet agents now have a Slack tool for listing channels the connected bot is a member of, making it easier to discover the right channel before posting or reading messages.

• Fleet OAuth provider and integration responses now include an owner field (workspace or platform) so you can tell your own resources apart from built-in, platform-managed ones. The platform manager organization can now create and modify built-in OAuth providers.

• Setting up a schedule is now clearer: choose a preset (daily, weekly, monthly, or every few minutes) or enter a custom cron expression, with a live human-readable preview and inline validation as you go.

• When registering an integration OAuth provider for headless connections, http:// redirect URIs are now accepted only for the loopback IP literals 127.0.0.1 or [::1]. The localhost hostname is no longer accepted over http — use the loopback IP literal or https.

Fixes

• On the Agent Builder Integrations page, searching now selects the All tab so results span every category, and switching category tabs clears the search.

• When a Fleet agent’s subagent calls a tool that requires human approval, the approval prompt now appears in the chat instead of the run completing without it.
