Docker SBX v0.26.1: Diagnostics, OAuth, Template Management

TL;DR

• New sbx diagnose command for collecting and uploading sandbox diagnostics
• Template management expanded with save, load, ls, and rm commands
• OAuth flows now work inside sandboxes with xdg-open shim and localhost callbacks
• Factory.ai agent support added; Claude download domains whitelisted by default

New

• sbx diagnose — Collect and upload diagnostic data when troubleshooting sandbox issues
• Template commands — sbx template save, load, ls, and rm for full template lifecycle management
• OAuth in sandboxes — xdg-open shim and localhost callback support enable browser-based auth redirects to work seamlessly
• Factory.ai agent — New agent with dedicated template now supported
• Daemon log rotation — Automatic log rotation for daemon logs; improved logging in foreground and debug modes
• Claude domains whitelisted — downloads.claude.ai and claude.com added to default proxy allow list
• Template agent warnings — Warn when loading a template built for a different agent

Fixed

• Stopped sandbox no longer disappears from list when a prefix-named sandbox is running
• New sessions no longer killed by in-progress auto-stop
• Exec command-not-found detection now reads from stdout and stderr correctly
• Ghostty launch on macOS now uses file-based launch
• Terminal background color detection now uses actual terminal appearance instead of system settings
• Domain-allow rules now correctly override implicit CIDR denies for IP address literals
• Policy denial log messages now more accurate and detailed
