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 pane & dashboard mods
beads-band
3baselane-sh/mods
A band above the prompt with your beads counts (bd 97 ready · 45 active · 29 blocked), read with bd status every 2 minutes and after Claude runs bd. Hidden without bd or a beads project.
outputs
3seanrobertwright/claude-mods
A pane listing the files this session has made or changed, newest first; click one to open it.
job-watch
2joeldg/claude-mods
Live pane of long-running jobs (training, downloads, extractions): progress, ETA, stalls and finishes, read from their logs with no model calls; jobs_list / jobs_watch / jobs_unwatch tools so Claude follows jobs instead of polling them.
haiku-first
2mako-code/gobworks
Opt-in: questions about the codebase (where is, what does, how does, which file, find) go to a read-only haiku scout subagent first; its answer comes with Ask Claude anyway and Good enough, and the tokens saved.
auto-continue
2mako-code/gobworks
Keeps work flowing: when Claude stops mid-task ("Next I'll…") or asks an obvious yes ("Shall I continue?"), a 5-second countdown you can stop sends a short continue. Never for choices, missing info or risky steps.
