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. Source confirms automatic postinstall setup of the package's own skill in user-level agent directories, including recursive deletion and replacement. This is a guarded-category warning under the policy, with no verified broader control-surface hijack or separate malicious chain in the inspected evidence. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-12T11:14:54.623Z - **Finished:** 2026-10-12T11:15:29.977Z - **Download time:** 1258 ms - **Static scan time:** 1111 ms - **AI review time:** 32983 ms - **Total time:** 35354 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:** Postinstall replaces skill directories under the user's home directory with this package's skill bundle. This is first-party agent skill setup, but it runs automatically during package installation. - **Trigger:** npm install invokes the package's postinstall script. - **Impact:** Existing contents at those selected skill paths can be deleted or replaced, and agent behavior may be affected by the installed skill. - **Evidence paths:** package.json, install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T11:15:29.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer selects default Codex, Claude, and cc-switch skill locations, recursively removes each target, then copies its bundled skill directory into place. - **Rationale:** Source confirms automatic postinstall setup of the package's own skill in user-level agent directories, including recursive deletion and replacement. This is a guarded-category warning under the policy, with no verified broader control-surface hijack or separate malicious chain in the inspected evidence. - **Files touched:** ~/.cc-switch/skills/lj-awb, ~/.codex/skills/lj-awb, ~/.claude/skills/lj-awb ### 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 install.mjs during postinstall., install.mjs defaults to skill directories for Codex, Claude, and cc-switch under the user's home directory., The installer recursively removes each target directory and copies the package's skill bundle there. - **Evidence against:** The installer supports an explicit skip flag and an explicit target directory., The inspected runtime code uses the package's configured API origin and the update check caches version information. ## Affected versions and remediation This report applies to @lingjingai/lj-awb-cli-pre@0.5.20. - Review the evidence and your use of @lingjingai/lj-awb-cli-pre@0.5.20 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.
