What the publisher says
From the Knowl repository's README, as published. We do not edit it. Read it on GitHub
Your CLAUDE.md only grows. Knowl retires facts when they change.
Quick start · Why supersession · What gets stored · Features · Agent setup · Viewer · Requirements · Full reference →
Your agent starts every session blank, so you keep a CLAUDE.md. It only grows. Six months in it still names the database you migrated off last spring, and now the agent gets both answers.
Knowl is persistent memory for Claude Code, Cursor and Codex, over MCP or the CLI. When a fact is replaced, the old one is retired instead of competing with the new one. No API key needed. When Knowl isn't sure the new fact replaces the old, it leaves both active and hands you the knowl supersede command to say so.
Turn that off and retrieval drops from 98% to 47%. End to end, 90 to 73. How it was measured ↓
Forty seconds, one decision, three agents:
Quick start
Requires Node.js 22 or later. macOS, Linux and Windows.
npm install -g @dat999zx/knowl

pnpm add -g @dat999zx/knowl
yarn global add @dat999zx/knowl
bun add -g @dat999zx/knowlOr run it without installing:
npx @dat999zx/knowl initShortened. The full README is on GitHub.
