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 a local postinstall dispatcher whose module performs a repair check and prints setup prompts. Agent configuration changes and scheduled maintenance are reached through explicit initialization, and no concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-11T06:10:23.023Z - **Finished:** 2026-10-11T06:11:17.127Z - **Download time:** 777 ms - **Static scan time:** 3472 ms - **AI review time:** 49852 ms - **Total time:** 54104 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. The postinstall hook dispatches to local package code that performs a Codex repair check and prints setup prompts. - **Trigger:** Package installation triggers postinstall; agent integrations and scheduled maintenance require the user to run hippo init. - **Impact:** No confirmed attack surface was established. Explicit setup changes agent configuration and registers project maintenance, but is user-invoked. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T06:11:17.127Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall does not invoke agent initialization. The explicit init command detects existing agent files, patches instruction files and installs hooks; the scheduler records workspaces for daily maintenance. - **Rationale:** Source inspection found a local postinstall dispatcher whose module performs a repair check and prints setup prompts. Agent configuration changes and scheduled maintenance are reached through explicit initialization, and no concrete malicious behavior was identified. - **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli/init.js, dist/cli/scheduler.js, dist/cli/shared.js, dist/support-bundle.js ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package manifest routes postinstall to a local script, which then imports the package’s local postinstall module., Agent hook detection is in the explicit init command; the install hook does not invoke it., The scheduler records workspaces and runs maintenance commands for registered projects., Server requests use the detected Hippo server and the package’s configured API key., The support bundle collects environment variable names and redacts configuration values with secret-like keys., The postinstall module’s remaining behavior prints setup prompts; it does not write agent settings. - **Evidence against:** The package has a postinstall lifecycle hook, and explicit initialization can modify detected agent instruction files and install hooks., The code includes optional dynamic module resolution for Transformers.js dependencies. ## Affected versions and remediation This report applies to hippo-memory@1.70.0. - Review the evidence and your use of hippo-memory@1.70.0 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.
