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
eventlog-context
1radiator-engineering/eventlog
Replaces context compaction in the controller's interactive session of a log-driven repo: the conversation is rebuilt from .context/events.jsonl by `eventlog context`, plus the last few turns word for word. Rebuilds at the log's task boundaries and at a fill backstop; /rebuild queues a rebuild for the end of the next turn, and /compact rebuilds from the log at once. Inert in headless sessions, for other EVENTLOG_AS writers, with EVENTLOG_CONTEXT=off, and in a repo without the log. Falls back to the engine's compaction when eventlog fails.
gear
1moelahmady/jev-model-router
Routes each turn's reasoning effort with TypeSafe's Jev decision model, keeping the prompt cache (Claude Code 2.1.280+). Model routing is available but off by default and refused above maxSwitchTokens, since a model switch re-writes the whole context.
eta
1hamza-siddiq/claude-eta
Time left on the working turn, on the spinner line: from the task list's pace, else from how long your turns run. No model calls, no tokens. /eta turns it on or off.
headroom
1MWEJ/claude-code-headroom
Your Claude plan limits, a forecast of when you'll run out, and your context window, live in a band above the prompt. Compacts in one click, automatically, or when Claude picks the moment, and keeps the prompt cache warm
echo-widget
1echo724/echo-claude-mod
Widgets above the prompt, each in its own box and switched on or off by a command: a pomodoro timer, a calendar and the context window as Tetris
headroom
1vihrea1337/headroom
Headroom: rate-limit countdowns and a burn-rate forecast for Claude Code. When each window resets, whether it lasts at this pace, alerts at 80/95% and on reset, a session budget, a week of history and a clickable prompt log
