cmux-settings

cmux reads user settings from ~/.config/cmux/cmux.json (JSONC). A file watcher applies changes on save, no restart. Legacy ~/.config/cmux/settings.json is read only as a fallback for keys absent from cmux.json.

Schema: https://raw.githubusercontent.com/manaflow-ai/cmux/main/web/data/cmux.schema.json. The authoritative path list is Sources/CmuxSettingsJSONPathSupport.swift; the installed skill carries a generated copy in references/all-keys.md. Settings sections are app, terminal, notifications, sidebar, sidebarAppearance, workspaceColors, automation, browser, shortcuts. Non-settings sections (actions, ui, commands, vault, rightSidebar) share the same file.

Helper script

Use the bundled helper for every read/write. It strips JSONC comments, writes atomically, and validates keys against the schema.

The rest of this doc assumes it is on $PATH as cmux-settings; from a checkout, export PATH="$PWD/skills/cmux-settings/scripts:$PATH".
