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
prompt-status
1matr1xp/local-mods
Two-line status above the prompt: model, directory, git branch, context fill and rate-limit usage
quota-band
1kuan0808/cliproxy-kit

prompt-forge
1tomikng/prompt-forge
Spends your Claude Code tokens where they count: moves a new task into a fresh session (a new terminal window, or its own git worktree) instead of dragging a long conversation along, and runs small, clear tasks on Sonnet.
regia

A graphic control room for Claude Code: a live radar of agents, skills and tools, with context and usage limits, in motion.
prompt-cache-control
1Nasrallah-Adel/claude-prompt-cache-control
Prompt-cache meter above the Claude Code prompt: how many tokens each request read from, wrote to and sent past the cache, a live countdown to the cache's expiry, and what to do about it (keep going, compact or clear). The TTL follows Claude Code's own rules for your account (1 hour on a Claude subscription, 5 minutes on an API key, cloud provider or usage credits, plus the TTL variables and setting) and corrects itself from request timing. /cache opens a per-turn table. A Clear button writes a handoff brief from the transcript with a cheap model, runs /clear, and sends the brief to the fresh conversation.
review-gate
1rlorenzo/ai-coding-setup
The review gate as a tool.check function hook. Every shell call is decided in process, so the non-commit calls -- almost all of them -- cost no subprocess at all, and a blocked commit can be put to you as a question instead of refused outright. The decision itself is still bin/review-gate, run only for a command that mentions a commit, so both routes read the same receipts and cannot disagree.
