End-user control of cmux topology and routing (windows, workspaces, panes/surfaces, focus, moves, reorder, identify, trigger flash). Use when automation needs deterministic placement and navigation in a multi-pane cmux layout.

cmux testing rules for Swift Testing, test target compilation, and package/refactor validation. Use when adding or changing tests, touching package/refactor code, or deciding whether reload.sh is enough validation.
Stripe checkout, pricing, subscription, Pro plan, webhook, and entitlement runbook for cmux billing work. Use when editing or debugging billing, pricing, Stripe Checkout, subscription recording, Pro plan status, webhooks, entitlement metadata, or pricing dev/prod tooling.
View and edit cmux settings in ~/.config/cmux/cmux.json. Use when the user wants to change cmux preferences (appearance, sidebar, notifications, automation, browser, shortcuts), set a value by JSON path, validate the file, open it in an editor, or look up which keys cmux recognizes. Triggers on '/cmux-settings', 'change cmux setting', 'set <something> in cmux', 'cmux config', 'cmux.json', or 'rebind a cmux shortcut'.
Debug logging, Debug menu, runtime pitfalls, typing-latency-sensitive paths, SwiftUI list snapshot boundaries, OS-version repros, and local visual iteration for cmux. Use when adding debug probes, diagnosing UI/runtime issues, touching terminal rendering, tab/sidebar list views, drag/drop UTTypes, or using the Debug menu.
Build a custom cmux sidebar from a plain-language request. Use when the user asks for a custom sidebar, a sidebar that shows their workspaces/tabs/PRs/clock, a vibe-coded sidebar, or anything involving files in ~/.config/cmux/sidebars/. Covers authoring the interpreted SwiftUI-style file, enabling the beta flag, selecting it, and iterating with hot reload.
cmux package architecture, refactor layering, dependency inversion, file organization, DocC documentation, package design discipline, testability, and Swift 6 concurrency rules. Use before adding or meaningfully rewriting Swift files, Swift packages, coordinators, services, repositories, or public package APIs.

Use cmux docs settings before changing cmux-owned settings. It prints the docs URL, schema URL, raw GitHub resources, cmux.json paths, and reload command.

cmux-owned settings live in ~/.config/cmux/cmux.json. Legacy ~/.config/cmux/settings.json and ~/Library/Application Support/com.cmuxterm.app/settings.json files are read only as fallback for missing keys. Before editing, copy any existing cmux.json file to a timestamped .bak next to it so the user can revert. Edit the user file, then reload:
cmux reload-config
cmux reload-config reloads BOTH cmux.json and Ghostty config (~/.config/ghostty/config) and refreshes terminals in place. No app restart needed.
Use cmux settings for app behavior, sidebar, notifications, browser behavior, automation, workspace colors, and cmux-owned shortcuts. Terminal rendering settings such as font, cursor style, theme, scrollback, background transparency (background-opacity), and blur (background-blur) belong in Ghostty config at ~/.config/ghostty/config.
Open the UI when useful:
cmux settings
cmux settings cmux-json
cmux settings shortcuts
