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 context & usage mods
polaroid
21ersinkoc/claude-mods
KOZMOS Polaroid: /polaroid snapshots the session as a self-contained dark-neon HTML report in .kozmos/reports: model, duration, cost, tokens, context peak, rate limits, tool calls by family, a timeline of turns, subagents, files touched and commands run, all collected live. It answers with the path and copies it. /polaroid md writes Markdown instead.
cache-tax
5partalemre/MODZ
A Claude Code mod that keeps the one-hour prompt cache warm during breaks and holds a cold send, after a break or a model change, on a card with its estimated rewrite cost. Warming uses model requests and costs tokens. Requires Claude Code 2.1.287+.
