One command. cc-sentiment sets up a verification key, scores your sessions, and uploads only aggregate numeric metrics to sentiments.cc.
Requires uv.
uvx cc-sentiment On macOS, set it up on a launchd schedule:
uv tool install cc-sentiment
cc-sentiment install Runs once a day in the background on macOS. On Linux or Windows, use cron or your platform's scheduler to run cc-sentiment run. Undo the macOS schedule any time with cc-sentiment uninstall.
The wizard sets up a verification key, scores your sessions with the best available engine, and uploads the numeric scores. If anything's missing, it'll guide you through setup.
~/.claude/projects/Your conversations are not uploaded to sentiments.cc. The private signing key stays on your machine. What gets uploaded: a score from 1-5, a timestamp, and a public verification handle (GitHub username or GPG fingerprint) used only to find a public key and verify signatures. What doesn't: conversation text, file contents, file paths, prompts, tool inputs, or tool outputs.
