How to install hippo-memory

npm install -g hippo-memory && hippo init --scan ~
npm install -g hippo-memory

Taken from the project's README on GitHub. Check the security audit before running it.

Security audit verdict: SAFE · quality 68/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About hippo-memory

🦛 Hippo The secret to good memory isn't remembering more. It's knowing what to forget. A memory layer for AI agents. Modeled on the hippocampus. Decay by default, strength through use, provenance on every memory. SQLite under the hood, zero runtime deps, works with every CLI agent you have. One command. Every git repo on your machine gets memory.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
