Copilot CLI v1.0.55: Claude Opus 4.8, MCP Tokens & Plan Mode

TL;DR

• Claude Opus 4.8 support added; free/student users locked to Auto model selection
• MCP server token usage now visible per-server; reasoning tokens reported in session summaries
• Native crashes fall back to JavaScript instead of silent exit; cell-based terminal renderer enabled by default
• Wayland clipboard, PowerShell 7 detection, and remote session management fixes

New

• Claude Opus 4.8 support — new model option available for eligible users
• Per-MCP-server token usage — /mcp and /context now break out token consumption by server and tool
• Reasoning token reporting — Claude thinking tokens now visible in session usage summaries
• /autopilot command — keeps autopilot focused; /goal works as alias
• Recursive agent discovery — custom agents and skills found in subdirectories
• MCP configuration screen — dedicated UI with scrollable server and tool lists
• Hook progress streaming — real-time status messages from long-running hooks in timeline
• pluginDirectories on RPC — SDK clients can mount Open Plugins-format directories per session
• Remote session deletion — delete sessions directly from picker
• permissions.disableBypassPermissionsMode setting — prevent allow-all/yolo mode

Fixed

• Native binary crashes (SIGSEGV) now fall through to JavaScript fallback instead of silently exiting
• Loading spinner no longer hangs in untrusted folders
• MCP server configuration form saves typed value on Ctrl+S
• PowerShell 7 detection works correctly with Microsoft Store App Execution Alias
• Sessions with zero-sized CAPI billing batches resume correctly
• Cell-based terminal renderer enabled by default for all users
• Clipboard paste works on Wayland compositors without wlr-data-control support
• Interactive shell tool preserves parent terminal color settings
• Canvas tools with optional object input schemas open without validation errors
• Extension subprocesses no longer fail with "Invalid command format" from older CLI versions
• Settings migration preserves user data from legacy snake_case keys
• Diff view keyboard shortcuts display correctly when toggling modes
• Terminal bell no longer sounds on turn completion unless explicitly enabled
• /resume picker no longer shows blank rows for closed sessions
• Aborting sessions no longer stuck in Cancelling state with Task tool agents
• Upward auto-scroll engages when dragging selection past timeline top
• Clipboard correctly copies CJK and supplementary-plane Unicode on Windows
• Selection background contrast increased across all color themes
• Extensions launch correctly when CLI runs as single-executable application (SEA)

Breaking Changes

• Free and Student plan users on token-based billing restricted to Auto model selection only
• --plugin-dir skills now take precedence over personal-home skills; order is project > plugin-dir > personal > custom
• exit_plan_mode tool only offered while session is in plan mode
• vote_memory tool calls throttled per response and interaction to prevent runaway voting bursts
