How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

More memory & instructions mods
auto-polish
2mako-code/gobworks
Every prompt you type gets a quiet second read: without changing your words, a hidden note gives Claude the goal in one line, the likely scope, the project's checks to keep green, and what done means. Haiku only for vague prompts; See, Undo and Off in the band.
context-handoff
2Ankitrai97/rai-claude-mods
A bar above the prompt showing how full the chat's context is (green under 60%, amber 60-80%, red above 80%), with an H button and /handoff to save a handoff note that the next chat in the project loads automatically.
apk-fraicheur
2DarkSawOktay/claude-mods
Android APK freshness: is the APK up to date with the code, build in progress and its duration, failures and out-of-memory caught at once, size, copy to another folder. For React Native / Expo / Gradle projects. French or English.
dnd
2robinalexandre/claude-code-kit
Do not disturb for the kit's panes: profiles that hide the history, the dev activity, the reminders or the handoffs, or keep only some repos and groups; turned on by hand, by Wi-Fi, by days and hours, or by folder. Its pane opens from the Configuration pane.
12ui-design
2just-every/12ui-plugin
A Design workspace in Claude Code: see design options for a UI as images, select one, ask for more, ask for a change with a note and hand an option off to be built. Your agent runs the 12ui command line once per request, which draws every option at once with your own Codex sign-in.
headspace
2Xabilimon1/emcc-claude-code-mods
What Claude carries, in colour: a bar above the prompt with system, rules, conversation and large tool results, and a pane to turn rules off for the session, edit and save them, and take out large results.
