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. LPM treats this as warn-only first-party agent extension lifecycle risk. Global installation automatically installs a package-owned AI skill through npx and copies it into assistant skill directories. Removing WorkBuddy's safe-delete preload adds unresolved protection-bypass risk, but no active malicious attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-02T16:56:13.350Z - **Finished:** 2026-10-02T16:57:12.544Z - **Download time:** 1284 ms - **Static scan time:** 157 ms - **AI review time:** 57753 ms - **Total time:** 59194 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:** Global installation automatically installs a package-owned AI skill through npx and copies it into assistant skill directories. Removing WorkBuddy's safe-delete preload adds unresolved protection-bypass risk, but no active malicious attack was established. - **Trigger:** A global npm installation outside CI without GUAN\_SKIP\_INSTALL\_SKILL=1, or an explicit install-skill command. - **Impact:** Assistant skill content can be added or refreshed automatically, with the targeted protection absent from installer child processes. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js, bin/install-env.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T16:57:12.544Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook launches the skill installer; its child environment strips the targeted safe-delete preload before running the installer. - **Rationale:** The source establishes guarded, package-owned agent extension setup with an additional protection-bypass concern. These facts support a warning rather than a malware publication block. ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json automatically invokes bin/postinstall.js after installation., The hook runs only for global installs outside CI, unless explicitly skipped., The hook invokes the install-skill command, which uses npx to install the package-owned guanwf skill globally., The launcher also copies the skill into CodeBuddy and WorkBuddy skill directories., The installer removes WorkBuddy's safe-delete preload from child-process environments. - **Evidence against:** The inspected installer targets the package's own skill rather than broad agent configuration., No credential exfiltration or destructive operation was established in the inspected JavaScript., The shipped native CLI binaries limit verification of ordinary runtime behavior. ## Affected versions and remediation This report applies to @guandata/guanwf@0.1.835. - Review the evidence and your use of @guandata/guanwf@0.1.835 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.
