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:** 2.88.7 - **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 is a user-invoked agent-skills installer, not an npm install-time hijack: there are no lifecycle scripts, and setup asks which tools to change. Scanner hits on the git-guard hook and localhost dashboard are product files, not a hidden payload or theft chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-18T01:56:47.628Z - **Finished:** 2026-09-18T02:02:44.137Z - **Download time:** 761 ms - **Static scan time:** 911 ms - **AI review time:** 354836 ms - **Total time:** 356509 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:** This package is an agent-skills installer. After the user runs setup, it can symlink skills, rules, and hook scripts into many AI-agent config directories. npm install itself does not run that installer, and no secret theft or remote payload was found. - **Trigger:** The user runs bigpowers setup, bigpowers-setup, or the optional bash scripts/install.sh path. - **Impact:** Selected agents may load package-authored skills, rules, and git-guard hooks from home-directory config paths. - **Evidence paths:** package.json, bin/setup.js, bin/bigpowers.js, scripts/lib/install-helpers.js, scripts/lib/install-targets-a.sh, .gemini/extensions/bigpowers/hooks/before-tool-git-guard.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-18T02:02:44.137Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-consented symlink and hook install into AI-agent config directories - **Rationale:** The package is a user-invoked agent-skills installer, not an npm install-time hijack: there are no lifecycle scripts, and setup asks which tools to change. Scanner hits on the git-guard hook and localhost dashboard are product files, not a hidden payload or theft chain. - **Files touched:** ~/.claude/skills, ~/.claude/hooks, ~/.claude/settings.json, ~/.gemini/config/plugins/bigpowers, ~/.gemini/hooks, ~/.gemini/settings.json, ~/.cursor/rules, ~/.codex/AGENTS.md, ~/.copilot/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The setup CLI and bigpowers-setup binary can symlink skills, rules, and hooks into many AI-agent home directories after the user picks tools and confirms., Gemini setup also links the first-party .gemini/extensions/bigpowers tree and hook scripts into ~/.gemini., The CLI notes that skipping npm lifecycle scripts bypasses the allow-scripts gate, then still requires a separate setup command., The optional update command can run npm install -g bigpowers@latest on a global install., A separate bash installer can merge hook entries into ~/.claude/settings.json and ~/.gemini/settings.json. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., index.js only exports the package name and version, with no import-time work., Setup is interactive, asks which tools to install, and requires a confirm step., The installer refuses to replace files that are not already package-managed symlinks., The dashboard server defaults to 127.0.0.1, and no credential harvest or webhook exfil was found., The flagged git-guard file is a short shell wrapper, not a hidden binary payload. ## Affected versions and remediation This report applies to bigpowers@2.88.7. - Review the evidence and your use of bigpowers@2.88.7 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.
