That's the problem provLedger solves. It's a Claude Code plugin that keeps a decision ledger for your project: every change records why it was made — your words, the email or meeting that settled it, the agent's own reading, kept apart and never blended. Two things make it different from a notes file: ``` claude plugin marketplace add yizhao95/prov_ledger claude plugin install provledger@provledger ``` Honest numbers: 199 unique cloners in 14 days, 26 stars, zero new stars in the window. Stars are a souvenir metric for CLI tools — the real signal is that clones spike on release days, i.e. existing users updating.
