Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection shows that hippo init can automatically modify detected agents’ instruction files and settings, a concrete agent configuration capability. The install hook’s Codex repair is limited to prior opt-in, so the supported verdict is a warning for the explicit CLI integration behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-07T20:27:21.108Z - **Finished:** 2026-10-07T20:28:48.124Z - **Download time:** 1291 ms - **Static scan time:** 3937 ms - **AI review time:** 81785 ms - **Total time:** 87016 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:** The package has an agent integration capability that can change project instruction files and user-level agent hooks. It is activated by running hippo init, and the inspected behavior supports a warning rather than a confirmed attack. - **Trigger:** A user runs hippo init in a project with detected agent configuration. - **Impact:** The command adds Hippo behavior to agent instructions and settings, affecting later agent sessions. No malicious exfiltration or unconsented install-time agent mutation was established. - **Evidence paths:** dist/cli.js, dist/cli/shared.js, dist/hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:28:48.124Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI patches existing agent instruction files and installs memory hooks for detected agents; Codex binary-wrapper installation is reserved for a separate explicit command. - **Rationale:** Source inspection shows that hippo init can automatically modify detected agents’ instruction files and settings, a concrete agent configuration capability. The install hook’s Codex repair is limited to prior opt-in, so the supported verdict is a warning for the explicit CLI integration behavior. - **Files touched:** dist/cli.js, dist/cli/shared.js, dist/hooks.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs a postinstall script, while dist/postinstall.js limits automatic wrapper repair to a wrapper already installed by a prior opt-in., Running hippo init can detect installed agents and automatically patch their existing instruction files and install user-level hooks., The CLI hook installer leaves Codex binary-wrapper installation to an explicit command, but installs Codex memory hooks when Codex is detected., The package adds Hippo memory instructions to agent instruction files, and the hook installer writes agent settings. - **Evidence against:** The inspected postinstall repair path does not perform a first-time Codex wrapper install., The observed agent configuration changes are tied to the explicit hippo init command and target detected agents. ## Affected versions and remediation This report applies to hippo-memory@1.60.0. - Review the evidence and your use of hippo-memory@1.60.0 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.
