Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found an install-time repair limited to an already opted-in Codex wrapper and agent hook setup reached through the explicit CLI init command. The flagged project, prediction, capture, embedding, and hook files provided no concrete attack behavior in the inspected excerpts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T05:42:10.565Z - **Finished:** 2026-10-09T05:42:43.733Z - **Download time:** 1012 ms - **Static scan time:** 4863 ms - **AI review time:** 27291 ms - **Total time:** 33168 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified in the inspected source. The package install hook performs repair for a previously opted-in Codex wrapper; agent hook setup runs from the CLI init command. - **Trigger:** Package installation invokes postinstall; project hook setup is triggered by running hippo init. - **Impact:** No unconsented first-time agent configuration change or concrete malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:42:43.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall calls a repair routine for an existing Codex wrapper. The CLI init command detects agent project files and adds hooks to existing instruction files. - **Rationale:** Source inspection found an install-time repair limited to an already opted-in Codex wrapper and agent hook setup reached through the explicit CLI init command. The flagged project, prediction, capture, embedding, and hook files provided no concrete attack behavior in the inspected excerpts. - **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli.js, dist/capture.js, dist/hooks.d.ts, dist/hooks.js, dist/embedding-provider.js, dist/project-identity.js, dist/src/project-identity.js, dist/predictions.js, dist/src/predictions.js ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares a postinstall wrapper that loads dist/postinstall.js; the postinstall code repairs a Codex wrapper only for users who previously installed it., Agent hook installation is called by the explicit hippo init command and can be disabled with --no-hooks., The init hook detector checks for agent-related project files, and the implementation patches an instruction file only when it already exists., The other flagged files contain project identity, capture, prediction, provider, and hook declarations or paths; the inspected excerpts show no concrete malicious behavior. - **Evidence against:** No inspected source shows credential theft, hidden network exfiltration, destructive behavior, or an automatic first-time agent configuration change during package installation. ## Affected versions and remediation This report applies to hippo-memory@1.38.0. - Review the evidence and your use of hippo-memory@1.38.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
