Copilot CLI v1.0.55-3: Hook Streaming & Plugin Management

Copilot CLI 1.0.55-3 adds hook progress streaming, plugin directory mounting for SDK clients, and remote session deletion. Fixes clipboard paste on Wayland, diff view shortcuts, and settings migration for legacy keys.

Copilot CLI v1.0.55-3: Hook Streaming & Plugin Management

TL;DR

  • Hook progress streaming now shows real-time status in the timeline
  • Remote sessions can be deleted directly from the picker; plugin precedence reordered (project > plugin-dir > personal > custom)
  • Fixed clipboard paste on Wayland, diff view shortcuts, and settings migration for legacy keys

New

  • Hook progress streaming — Long-running hooks now display real-time status messages in the timeline instead of silent execution
  • pluginDirectories on session RPC — SDK clients can mount Open Plugins-format directories per session via session.create and session.resume
  • Delete remote sessions from picker — Remove remote sessions directly without leaving the session selection UI

Improved

  • owner/repo#ref syntax for marketplace plugins — Cleaner syntax when adding plugins from the marketplace
  • Plugin precedence reordered — --plugin-dir skills now take priority over personal-home (~/.copilot, ~/.agents) skills. Full order: project > plugin-dir > personal > custom
  • Feedback dialog and /skills help — Updated to use Copilot-consistent log paths and terminology
  • tmux 3.6b progress integration — Progress indicators now work natively with tmux pane progress state
  • Reasoning token count in session summary — All users now see token counts for reasoning in session summaries
  • Remote session policy messaging — Helpful message when remote controlled sessions are disabled by organization policy

Fixed

  • Schedule manager hint bar text no longer wraps over dialog borders
  • copilot update and copilot version now authenticate release API requests to avoid rate limits in shared-NAT environments
  • Diff view keyboard shortcut hints display correctly when toggling between unstaged and branch diff modes
  • Clipboard paste now works on Wayland compositors without wlr-data-control support (GNOME/Mutter)
  • Interactive shell tool preserves parent terminal color settings for full-color diff tools and programs
  • Canvas tools with optional object input schemas open without validation errors
  • Extension subprocesses no longer fail with "Invalid command format" when forked from older CLI versions
  • Settings migration preserves user data when legacy snake_case keys exist from older versions

Update via: copilot update
