hippo-memory@1.52.3
Biologically-inspired memory for AI agents. Zero runtime deps, SQLite, MCP server, and an opt-in hosted TypeSafe Jev reranker. Decay, retrieval strengthening, consolidation.
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe package does have an install hook, but source inspection shows it repairs an already opted-in Codex wrapper and otherwise prints setup instructions. Agent hook and plugin setup is performed through CLI setup, with no inspected evidence of malicious behavior.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Package installation runs the postinstall hook; agent setup requires a user to run hippo init or a hook installation command.
Impact
No confirmed attack surface was established; the inspected source shows no install-time first setup of agent configuration or credential exfiltration.
Mechanism
The postinstall hook checks or repairs an existing Codex wrapper and prints opt-in instructions. CLI setup adds package-owned hooks or a plugin to detected agent configuration.
AI rationale
The package does have an install hook, but source inspection shows it repairs an already opted-in Codex wrapper and otherwise prints setup instructions. Agent hook and plugin setup is performed through CLI setup, with no inspected evidence of malicious behavior.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json routes imports to dist/index.js and declares a postinstall script.
- dist/capture.js reads a transcript path supplied in hook input, or scans Claude project transcripts when that input is absent.
- dist/cli.js detects agent configuration files for hook setup; the setup path patches an instruction file only when it already exists.
- dist/hooks.d.ts exposes separate OpenCode plugin install and uninstall operations.
- dist/hooks.js stores Codex wrapper metadata under the user’s .hippo directory.
- dist/postinstall.js limits Codex wrapper work to repair for users who previously opted in; it describes first-time installation as an explicit command.
- The postinstall message directs users to run hippo init or an explicit hook install command for agent setup.
- dist/embedding-provider.js describes API embedding providers as opt-in and the local provider as the default.
Evidence against
- The package has an npm postinstall hook that imports dist/postinstall.js.
- The CLI can add hooks to detected agent configuration during hippo init, including an OpenCode plugin.
