The package has AI-agent integration lifecycle behavior. Install-time repair is limited to a pre-existing Hippo Codex-wrapper record; the OpenClaw plugin removes only Hippo-named stale backup directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-15T14:16:07.941Z - **Finished:** 2026-08-15T14:17:30.907Z - **Download time:** 504 ms - **Static scan time:** 6860 ms - **AI review time:** 75600 ms - **Total time:** 82966 ms ## Security analysis ### Published attack-surface review - **Summary:** The package has AI-agent integration lifecycle behavior. Install-time repair is limited to a pre-existing Hippo Codex-wrapper record; the OpenClaw plugin removes only Hippo-named stale backup directories. - **Trigger:** npm postinstall with existing Hippo Codex metadata, or OpenClaw plugin registration. - **Impact:** Can modify a previously opted-in Codex launcher integration and remove \`hippo-memory.bak\*\` extension directories; no unconsented first-install mutation or exfiltration was confirmed. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/hooks.js, dist/cli.js, extensions/openclaw-plugin/index.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-15T14:17:30.907Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Guarded repair of an opted-in launcher wrapper and cleanup of first-party extension backups. - **Rationale:** This is a guarded first-party AI-agent extension lifecycle risk, not concrete malicious behavior. Warn so users can evaluate its launcher-wrapping and plugin-cleanup capabilities. - **Files touched:** dist/postinstall.js, dist/hooks.js, extensions/openclaw-plugin/index.ts, ~/.hippo/integrations/codex.json, detected Codex launcher, ~/.openclaw/extensions/hippo-memory.bak\* ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall imports lifecycle code that repairs an already opted-in Codex launcher wrapper., The OpenClaw extension deletes name-limited hippo-memory backup directories during plugin registration. - **Evidence against:** First-time Codex wrapping is guarded by existing Hippo metadata; absent metadata returns without changes., Agent hook and wrapper installation are exposed through explicit \`hippo hook install \\` commands., Postinstall only reads Claude settings to decide whether to print an opt-in message; it does not patch them., Observed network code is for configured AI embedding/LLM providers, not a hidden package-controlled endpoint. ## Public findings ### 1.
