Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 1.1.1 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms automatic, unguarded mutation of project-level agent configuration during postinstall. The setup is package-aligned, 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:** 91.0% - **Started:** 2026-10-20T04:27:18.539Z - **Finished:** 2026-10-20T04:27:45.594Z - **Download time:** 1028 ms - **Static scan time:** 19 ms - **AI review time:** 26007 ms - **Total time:** 27055 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:** Installation automatically adds this package’s instructions to project-level AI agent configuration. - **Trigger:** The npm postinstall hook runs during package installation. - **Impact:** The package gains influence over later agent behavior in the consuming project without a separate setup confirmation. - **Evidence paths:** package.json, scripts/install-anchors.js - **Review source:** ai\_review - **Reviewed:** 2026-10-20T04:27:45.594Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes a Cursor rule and a Kilo rules anchor directing agents to load the package’s AGENTS.md as their highest action standard. - **Rationale:** Source confirms automatic, unguarded mutation of project-level agent configuration during postinstall. The setup is package-aligned, so this warrants a warning rather than a block. - **Files touched:** .cursor/rules/mdd-ai-eng.mdc, .kilocoderrules ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook automatically runs the anchor installer., The installer writes a rule directing agents to load this package’s AGENTS.md as their highest action standard., It writes project-level Cursor and Kilo configuration without a consent check., The README describes this as the package’s intended agent-setup behavior, but installation still triggers it automatically. - **Evidence against:** The installer points agents to this package’s own specification files, and the README describes the configuration changes as the package’s intended function. ## Affected versions and remediation This report applies to @mdd-ai-eng/specs@1.1.1. - Review the evidence and your use of @mdd-ai-eng/specs@1.1.1 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.
