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 shows that the flagged agent configuration changes are reached through the user-invoked init flow, while npm postinstall performs repair for an existing Codex wrapper and prints read-only prompts. The available excerpts do not establish a concrete attack or credential exposure. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T05:43:23.063Z - **Finished:** 2026-10-09T05:44:34.492Z - **Download time:** 768 ms - **Static scan time:** 5088 ms - **AI review time:** 65571 ms - **Total time:** 71429 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 confirmed attack surface was established. The user-invoked init flow can add Hippo hooks to existing agent instruction files, while installation itself limits agent integration to repair of a previously opted-in wrapper and setup prompts. - **Trigger:** The package postinstall hook runs on installation; agent hook setup is reached through the hippo init command. - **Impact:** The explicit init command changes local agent configuration; no concrete malicious impact was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:44:34.492Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Init detects agent markers and appends a Hippo-marked block to an existing target file. Postinstall invokes wrapper repair and prints prompts. - **Rationale:** Source inspection shows that the flagged agent configuration changes are reached through the user-invoked init flow, while npm postinstall performs repair for an existing Codex wrapper and prints read-only prompts. The available excerpts do not establish a concrete attack or credential exposure. - **Files touched:** dist/cli.js, dist/postinstall.js, scripts/postinstall.cjs ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** npm postinstall runs a wrapper repair and prints setup prompts; it does not perform first-time agent setup., The user-invoked init flow detects existing agent markers and appends hook configuration to an existing target file., The detected targets include Claude Code, Codex, Cursor, OpenClaw, OpenCode, and Pi configuration markers., The flagged capture excerpt reads Claude project directory entries; it does not establish credential collection or exfiltration., Provider code defines conventional vendor embedding endpoints; the inspected source did not establish an unrelated credential recipient., Prediction files map database row fields into records; their inspected excerpts show no attack behavior. - **Evidence against:** The package has a postinstall hook, but its source repairs a previously opted-in Codex wrapper and prints read-only prompts., The inspection did not establish unconsented install-time agent configuration changes or a concrete attack chain. ## Affected versions and remediation This report applies to hippo-memory@1.44.0. - Review the evidence and your use of hippo-memory@1.44.0 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.
