Claude Code plugin that scores how well you prompt a coding agent

Claude Code plugin that scores how well you prompt a coding agent and shows whether your habits improve over time, running on TypeSafe's Jev model. It adds no latency: by default the hook writes one line to a local file and exits, and scoring only happens when you run a command. Seven habit checks cover things like naming the file or function, stating constraints and saying how to verify the result. It can also score the prompts you've already written, so a backfill over a year of Claude Code history (about six cents) gives you a report on day one. Everything is redacted before it's sent, tool output and thinking never leave your machine, and a metadata-only mode sends no text at all. Bring your own TypeSafe API key. Unofficial community plugin, not affiliated with TypeSafe or Anthropic.
