Summary

Cline CLI 3.0.56 lets image-capable models return media through the TUI, HTML exports and ACP clients, and changes skill slash commands to load through the skills tool without duplicating their instructions. It also restores provider-tool visibility, hook output and cancellation behaviour, and fixes remote schedule authorisation.

Why it matters

These changes make agent work more inspectable and portable across terminal, exported-session and client-protocol surfaces.
