Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (claude-vibe-check) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

claude-vibe-check

Claude Code hook that captures your webcam after each response and adjusts its behavior based on your facial expression.

Frustrated? It asks what went wrong. Confused? It explains more. Happy? It keeps going.

Install

npm install -g claude-vibe-check
claude-vibe-check setup

Requires a webcam and one of: fswebcam, ffmpeg, or imagesnap (macOS).

How it works

The setup command registers a Stop hook in ~/.claude/settings.json. Every time Claude finishes a response, the hook silently captures a photo and feeds your detected emotion back to Claude as context. A 60-second cooldown prevents it from firing too often.

Modes

Online (default) — sends the photo to Claude for visual analysis.

Offline — runs a local CV model, photo never leaves your machine. Dependencies install automatically.

claude-vibe-check mode offline            # uses hsemotion by default
claude-vibe-check mode offline fer        # or pick fer backend

Vibe Stats

Every vibe check in offline mode is logged automatically. Run stats to see your emotion patterns over time, broken down by project, time of day, and daily trends.

claude-vibe-check stats              # all time
claude-vibe-check stats today        # today only
claude-vibe-check stats week         # last 7 days
claude-vibe-check stats my-project   # filter by project name

History is stored in ~/.config/claude-vibe-check/history.jsonl and can be cleared with claude-vibe-check history clear.
