Copilot CLI v1.0.12-2: Plugin Hooks & MCP Fixes
Plugin hooks get environment variables, MCP servers load correctly, and reasoning effort levels now display in the model header. Alt screen always on.
TL;DR
- Plugin hooks now get project directory and plugin data environment variables
- Model header displays active reasoning effort level
- Workspace MCP servers now load correctly and persist across /clear
- Alt screen flag removed — always enabled now
New
- Plugin hook environment variables — hooks receive CLAUDE_PROJECT_DIR and CLAUDE_PLUGIN_DATA, plus {{project_dir}} and {{plugin_data_dir}} template variables for configuration.
Improved
- Model display header — shows active reasoning effort level (e.g., "(high)") next to the model name for clarity.
- /session rename — auto-generates session names from conversation history when called without arguments.
Fixed
- Workspace MCP servers are now correctly loaded and visible to the agent.
- /clear command preserves MCP servers in the new session.
Removed
- --alt-screen flag and alt_screen setting — alt screen is now always enabled; no configuration needed.
