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.

clauget

The scale, then the diet — and the diet only where the scale says it pays. Each model request inside a turn streams through one hook, whose stop chunk carries the four token counters and the model that answered, so the journal has a line per step, the main loop's and every subagent's apart, and names the cache misses where they happen. /clauget opens the report: the window and the cost, the bill of the prefix by provider with how often each provider's tools were called, the break-even of deferring, the instruction files, and every lever with what it saved and what it cost. Out of the box the mod measures and changes nothing. /clauget on, off or strict turns the levers on from the next session: a policy on the prefix decided once and never moved mid-session, tool results cut to the shape of their fat and filed whole so one Read undoes a cut, a small-prefix explorer agent, a lighter transcript for the compaction, economy tiers that tighten with the plan window, a forecast of when it fills, and prompts deferred to its reset. Each lever was measured on a real session; the ones that lost were closed and are named in the README. Nothing the mod writes reaches the model unless a lever puts it there, and then it is counted in the mod's own column.
