Managed setting — stops a user-installed mod from loading; the plugin itself stays installed, with its skills, commands, agents and MCP servers still loading
Hold every Claude model with a native 1M context window to 200K via auto-compaction
A startup warning appears when auto-compaction isn't holding the session to 200K
Opus 4.7+ and Fable now default to a 1M window with no [1m] model-id suffix needed, on Bedrock, Vertex, Foundry and the Claude apps gateway; set this to 1 to keep 200K
Session additional working directories (from /add-dir) are included in MCP roots/list; notifications/roots/list_changed sent to servers when the set changes
