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
lookout
1StartupBros-com/hov-marketplace
A second pair of eyes while Claude works. Every few model steps it asks one tool-less fork of the session (served from the prompt cache) whether there is something you should know and might miss, and shows the answer above the prompt. No model call while nothing draws the session.
model-picker
1juampymdd/claude-code-model-picker
A band above the prompt to pick which model, and which version of it, runs the next requests, with cost, tokens and cache stats an animated pane of charts and live agents for the whole session, and a tab where Claude notes the theory behind what it builds.
lk-token-budget
1connectwithub/loopkeeper
Stop runaway token spend: budgets per session and per subagent with warn, deny-agents or stop actions, plus a prompt-cache countdown, cold-cache pings and keep-warm.
model-router
1TFoxik/claude-model-router
Model and effort routing per kind of work, with prompt-cache and cost tracking, a cold-cache guard, and an optional learn mode that explains what each choice cost
lk-agent-map
1connectwithub/loopkeeper
See and cap your subagents: cards with cost, tokens, context and progress, spawn caps with an override you approve, tree and team views, idle alerts and a Stop button.
neon-hud
1ezequielcutin/claude-hud-plugin
A live HUD above the prompt: turn timer, active skill, subagent tree, git state, rtk token savings and one-click session checkpoints
