The package offers opt-in AI-agent hooks and a Codex launcher wrapper. Its install hook only repairs a wrapper indicated by existing Hippo metadata; no unconsented first-time control-surface mutation is established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-23T13:14:47.675Z - **Finished:** 2026-08-23T13:15:42.880Z - **Download time:** 515 ms - **Static scan time:** 7075 ms - **AI review time:** 47613 ms - **Total time:** 55205 ms ## Security analysis ### Published attack-surface review - **Summary:** The package offers opt-in AI-agent hooks and a Codex launcher wrapper. Its install hook only repairs a wrapper indicated by existing Hippo metadata; no unconsented first-time control-surface mutation is established. - **Trigger:** npm postinstall after prior Codex-wrapper opt-in, or explicit hippo init/setup/hook install commands. - **Impact:** Can capture and process agent-session context after user-enabled integration. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/hooks.js, dist/cli.js, extensions/openclaw-plugin/index.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-23T13:15:42.880Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent hook installation and conditional launcher-wrapper repair. - **Rationale:** The package has a guarded lifecycle repair path and explicit AI-agent integration features, warranting a warning. Source inspection shows the postinstall avoids first-time wrapper installation and no concrete malicious behavior was found. - **Files touched:** ~/.hippo/integrations/codex.json, detected Codex launcher path, ~/.claude/settings.json, ~/.config/opencode/plugins/hippo.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** postinstall invokes a repair path for an existing Codex wrapper., The explicit hook command can replace the Codex launcher with a Hippo wrapper., Explicit hook setup writes Claude Code and OpenCode integration files. - **Evidence against:** Postinstall does not first-install the Codex wrapper; it requires prior wrapper metadata., Claude Code postinstall behavior is a visible nudge, not a config write., No source evidence of credential harvesting, exfiltration, remote payload execution, or stealthy broad config mutation. ## Public findings ### 1.
