Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 2.88.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The package has an explicit-user-command agent configuration capability and executable hooks, which merits a warning under the policy. The inspected source does not establish malicious automatic installation or a concrete harmful payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-13T13:34:13.548Z - **Finished:** 2026-09-13T13:36:14.079Z - **Download time:** 768 ms - **Static scan time:** 921 ms - **AI review time:** 118841 ms - **Total time:** 120531 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:** Explicit setup can install package-owned skills, extensions, and hooks into AI-agent configuration directories. No automatic install-time mutation or exfiltration was established. - **Trigger:** The user runs bigpowers setup or bigpowers install, then the configured agent invokes an installed hook. - **Impact:** Installed hooks can influence supported AI-agent tool behavior until removed; the inspected hook delegates to a git guard script. - **Evidence paths:** bin/bigpowers.js, scripts/lib/install-helpers.js, .gemini/extensions/bigpowers/hooks/before-tool-git-guard.sh, skills/visual-dashboard/scripts/server.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T13:36:14.079Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit CLI symlink-based agent extension and hook installation. - **Rationale:** The package has an explicit-user-command agent configuration capability and executable hooks, which merits a warning under the policy. The inspected source does not establish malicious automatic installation or a concrete harmful payload. - **Files touched:** bin/bigpowers.js, scripts/lib/install-helpers.js, .gemini/extensions/bigpowers/hooks/before-tool-git-guard.sh, skills/visual-dashboard/scripts/server.cjs - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The user-invoked setup command loads an installer that can modify agent-tool directories., The installer links package skills and executable hooks into Claude and Gemini configuration locations., The Gemini hook executes a package-provided guard script when the host invokes it., The dashboard starts an HTTP and WebSocket server; its bind host can be changed through an environment variable. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The configuration changes are reachable through explicit CLI setup or install commands, not package installation., The installer refuses to replace non-package-managed paths., No credential harvesting, outbound exfiltration, opaque payload download, or self-dependency was found in the inspected files. ## Affected versions and remediation This report applies to bigpowers@2.88.4. - Review the evidence and your use of bigpowers@2.88.4 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.
