Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 27 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.4.21 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The source inspected supports ordinary CLI, bundled parser, and sandbox functionality, with no confirmed attack behavior. The manifest's prepublishOnly hook runs package tests and does not provide an automatic consumer install trigger. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-08T21:07:26.389Z - **Finished:** 2026-10-08T21:08:48.878Z - **Download time:** 1522 ms - **Static scan time:** 31852 ms - **AI review time:** 49114 ms - **Total time:** 82489 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 was identified in the inspected source. The flagged instruction-file locations perform workspace reads as part of CLI review plumbing. - **Trigger:** The CLI's applicable review flow invokes the instruction-file reader. - **Impact:** No malicious side effect or unconsented control-surface mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T21:08:48.878Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It reads AGENTS.md from the workspace and returns an empty string when the file is absent; the adjacent code submits an approval review event. - **Rationale:** The source inspected supports ordinary CLI, bundled parser, and sandbox functionality, with no confirmed attack behavior. The manifest's prepublishOnly hook runs package tests and does not provide an automatic consumer install trigger. - **Files touched:** AGENTS.md ### Review decision - **Verdict:** Clean - **Confidence:** 76.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI and prepublishOnly runs the package test build; it declares no install-time hook in the inspected scripts., The three flagged AGENTS.md locations read a workspace instruction file and treat a missing file as empty; the adjacent code is ordinary approval review plumbing., The required tools and web assets are bundled code, and the VBScript file begins with a parser implementation., The execution sandbox imports process and DNS APIs, consistent with the package's execution sandbox component; this alone does not establish an attack. ## Affected versions and remediation This report applies to tnega@0.4.21. - Review the evidence and your use of tnega@0.4.21 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.
