/plugin marketplace add DJPalefaceSD/rostech-mods
/plugin install horn@rostechMods install like plugins. Run /reload-plugins or start a new session to load it.

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.

Instagram Reels open while Claude is working, and close when the turn ends or Claude is waiting on you
forge
devohmycode/claude-mods
Make your own plugins and mods, and catch what a mod breaks without a word before a session loads it. /forge new writes a mod (or a classic plugin) in this repository's shape; /forge lint reads the source for the failures the loader refuses or that fail silently ($ bound to a name, a computed event or env name, two hooks with no matcher on one event, a plugin noun's verb hooked, a .catch that calls next twice, a $.config.set that reloads for nothing, a test plugin whose register delegates); /forge check adds tsc, claude plugin validate --strict with its inventory compared to what the source spells, and claude plugin test. Nothing runs unless the command is typed, and nothing reaches the model but the command's output.
