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
context-view
1kongyo2/context-view
The context window as one row above the prompt, drawn the way Claude Code draws its own meters: the context's cells, the percentage used, the tokens over the window, and the tokens left before auto-compact. /context-view hides and shows it. With the awareness option on, Claude itself reads the same figures in a line after your prompts and its tool results, from the point you set, such as 400k tokens.
cozy-clawd
1evrytests-maker/cozy-clawd
A cozy band above the Claude Code prompt: context, cache and limits at a glance, with an animated Clawd who keeps your prompt cache warm
context-pane
1akagaya/claude-code-mods
Shows what the conversation's context holds in a side pane: files, skills, MCP servers and memory files
crew
1flaviorg/crew
A live panel of the subagents Claude delegates to: model, context, tokens, cost and time, each with an animated mascot.
context-meter
1vienna-bio-center/claude-vbc-mods
Always-on context window meter above the prompt, with usage limits (terminal and desktop app)
ctx-cache-band
1gregpa/ctx-cache-band
Band above the prompt: context window used/max and prompt-cache TTL countdown + hit rate; optional auto-compact just before the cache expires.
