MCP Integrations

• New Integrations page for connecting third-party tools to your sandboxes
• Connect Sentry and Linear via OAuth — credentials are automatically configured in your sandbox environment
• Manage integrations per-organization from the sidebar

Multi-Agent Support

• Connect your own Codex credentials to use alongside Claude in sandboxes
• Choose which agent credentials to use when creating a sandbox
• Codex CLI is auto-configured in sandboxes when credentials are connected

Sandbox Improvements

• Auto-branch creation: A new git branch is automatically created for each sandbox, with the option to override the generated name or use an existing branch
• Searchable branch picker in the Create Sandbox dialog

CLI

• agent-send now works over the API instead of SSH, with session management for ongoing conversations
• Added ls shorthand for list commands (sandbox ls, service ls, volume ls, secret claude ls)
• Added rm shorthand for secret claude delete
• Added secret codex push, secret codex list, and secret codex delete commands for managing Codex secrets
• Added --no-setup flag to sandbox create to skip running setup scripts
• Sandbox list is now sorted by most recently created
• Fixed shell prompt colors on light terminal backgrounds
• Sandbox containers now include .bashrc alongside .zshrc

API

• API errors now return structured JSON with consistent error codes
• Non-existent API routes return a proper JSON 404 instead of HTML

OpenCode Credentials

• Store and manage your OpenCode credentials from the Settings page
• Credentials are securely resolved from the vault and injected into sandboxes on create and start

Bug Fixes and Improvements

• Sandbox start and stop operations now return immediately with status polling in the background
• If sandbox setup fails, the error is now surfaced directly in the UI
• Improved sandbox detail page layout with refreshed icons and a proper 404 page
• Improved error messages for agent-send authentication failures
