Claude Code mod

windvane

Babysits a long Claude Code session so you don't have to: the context fill is watched, the recorder drafts the checkpoint, compaction happens at the right point with the state banked and the work is resumed, the rules and the checkpoint ride inside the compacted conversation and every subagent's prompt, tool results are trimmed and secrets redacted at the door, project memory and rules are a tool call away, and a token ledger, a pane and a status segment show where the session stands.

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.
