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. The package has an install hook, but the inspected postinstall implementation performs limited repair and prints setup guidance rather than mutating an agent configuration. Agent integration and workspace registration occur through the package's setup flow, and no concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-07T20:26:54.204Z - **Finished:** 2026-10-07T20:27:24.625Z - **Download time:** 513 ms - **Static scan time:** 3875 ms - **AI review time:** 26030 ms - **Total time:** 30421 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 malicious attack surface was identified. Setup can add memory instructions and agent hooks through the CLI, while the install hook performs limited repair and prints guidance. - **Trigger:** Package installation triggers the postinstall script; agent setup is triggered by the user running hippo init or a hook installation command. - **Impact:** No malicious impact was established in the inspected source; user-invoked setup integrates Hippo memory with detected coding agents. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:27:24.625Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected postinstall repairs a previously installed Codex wrapper and prints setup nudges. CLI setup detects installed agent markers, updates existing instruction files, and installs hooks. - **Rationale:** The package has an install hook, but the inspected postinstall implementation performs limited repair and prints setup guidance rather than mutating an agent configuration. Agent integration and workspace registration occur through the package's setup flow, and no concrete malicious behavior was established. - **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli.js, dist/cli/shared.js, dist/hooks.js, dist/scheduler.js ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs a postinstall script that loads the package's own dist/postinstall.js., dist/postinstall.js limits install-time work to repairing a previously installed Codex wrapper and printing setup nudges; it does not install new hooks., Agent instruction files and hooks are installed through the hippo init flow, which detects existing agent markers and patches an existing instruction file., The package's instruction block describes Hippo memory commands and how to use them., The OpenCode plugin installer is exposed as a separate function; no malicious behavior is established by its declaration., The scheduler registers project workspaces and writes its registry as part of application setup. - **Evidence against:** The inspected capture path scans local Claude project transcripts only when its mayScan option is enabled., No source inspected established credential theft, unrelated data exfiltration, or a malicious install-time agent configuration write. ## Affected versions and remediation This report applies to hippo-memory@1.58.0. - Review the evidence and your use of hippo-memory@1.58.0 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.
