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. bigpowers is a user-invoked skills installer with no npm lifecycle scripts and no hidden network or credential sink in the cited entrypoints. Writing agent skill links happens only after an explicit setup command and confirmation, which matches the package purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-22T20:36:31.172Z - **Finished:** 2026-09-22T20:37:50.121Z - **Download time:** 1271 ms - **Static scan time:** 919 ms - **AI review time:** 76758 ms - **Total time:** 78949 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 surface was established. Agent skill and hook links are created only by the interactive setup command, and the dashboard listens on loopback when the user starts it. - **Trigger:** No install or import trigger runs the installer; the user must invoke bigpowers setup or the dashboard CLI. - **Impact:** No unconsented mutation, credential harvest, remote payload, or exfiltration was identified in the inspected entrypoints. - **Review source:** ai\_review - **Reviewed:** 2026-09-22T20:37:50.121Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup symlinks package skills and local git-guard hooks into directories the user selects, after a confirmation prompt, and skips destinations that are not already managed symlinks. - **Rationale:** bigpowers is a user-invoked skills installer with no npm lifecycle scripts and no hidden network or credential sink in the cited entrypoints. Writing agent skill links happens only after an explicit setup command and confirmation, which matches the package purpose. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no preinstall, install, or postinstall hook; the published bins are user-run CLIs., bigpowers setup and install only load bin/setup.js when the user passes that command., setup.js asks for a confirmation before syncing skills and installing selected tools., install-helpers.js refuses to replace a path that is not already a bigpowers-managed symlink., The Gemini before-tool hook only execs the local git guard script and otherwise returns allow., The visual dashboard HTTP server defaults to 127.0.0.1 and starts only when server.cjs is the main module. - **Evidence against:** Global setup can symlink this package's skills and hooks into home directories of many agent tools, but only after the user selects those tools and confirms., bigpowers update on a global install runs npm install -g bigpowers@latest, which is an explicit user command and not an install lifecycle. ## Affected versions and remediation This report applies to bigpowers@2.88.9. - Review the evidence and your use of bigpowers@2.88.9 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.
