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
cache-keeper
pauldandurand/claude-mods
One-line bar above the prompt with a live prompt-cache countdown, when your 5-hour usage resets, and Compact / Handoff buttons when the cache is about to expire.
cache-keeper
sorajate/claude-cache-keeper
Shows when the prompt cache lapses, keeps it warm with a few pings while idle, then compacts once and waits
cache-keeper
parab-aditya/cache-keeper
Keeps the main conversation's prompt cache warm while you are away, within a window you choose, and shows its state above the prompt.
cache-keepwarm
mupamuc/cache-keepwarm
Keeps the prompt cache of an idle Claude Code session warm: just before the cache lapses it submits a short service prompt, so your next message reads the context from the cache instead of writing it again. Off by default; /keepwarm on|off|status. Needs function hooks (early access).
cache-keeper
oioi555/claude-code-mods
Context, quota and prompt-cache meters above the prompt; while the session is idle on a 1-hour cache, keeps it alive and compacts before it lapses, holding off system sleep meanwhile (Linux, Windows, macOS).
cache-magic
AdamCaviness/cache-magic
Keeps a handoff while a large session's prompt cache is still warm. On a five-minute cache, a late prompt can go out after the handoff instead of the full context. On a one-hour cache the session stays, and compaction is pointed at the handoff.
