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 postinstall hook can delete recognized legacy DocNexus data without migration or confirmation, creating a concrete data-loss risk. Its narrow product-specific scope makes malicious intent unproven, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-21T13:04:56.306Z - **Finished:** 2026-10-21T13:06:20.132Z - **Download time:** 2056 ms - **Static scan time:** 482 ms - **AI review time:** 81287 ms - **Total time:** 83826 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:** The package has an install-time cleanup path that can delete data from older DocNexus project directories. The source limits cleanup to recognized legacy locations, but provides no migration or confirmation before deletion. - **Trigger:** Installing the package as a local project dependency when a recognized legacy DocNexus directory exists. - **Impact:** Existing DocNexus project data may be lost during installation. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/src/legacy-cleanup.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T13:06:20.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook calls cleanupLegacyProject, which recursively removes legacy workspace data and removes non-allowlisted entries from the internal directory. - **Rationale:** The postinstall hook can delete recognized legacy DocNexus data without migration or confirmation, creating a concrete data-loss risk. Its narrow product-specific scope makes malicious intent unproven, so this warrants a warning rather than a block. - **Files touched:** package.json, scripts/postinstall.mjs, dist/src/legacy-cleanup.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall.mjs on installation., The install hook invokes cleanupLegacyProject for a local project installation., The cleanup recognizes older DocNexus project formats and can recursively remove legacy project data without migration., The cleanup also removes entries from .docnexus that are outside its installation allowlist. - **Evidence against:** Agent skill linking and instruction-file updates occur through the explicit skills link command, not the install hook., The cleanup is restricted to identified DocNexus legacy directories; the source does not show broad deletion outside them. ## Affected versions and remediation This report applies to @rowansenne/docnexus@0.24.2. - Review the evidence and your use of @rowansenne/docnexus@0.24.2 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.
