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 an automatic install-time setup that modifies project agent rules and promotes package-provided instructions. This matches first-party agent extension lifecycle risk; the inspected code does not establish a broader attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-20T06:47:44.214Z - **Finished:** 2026-10-20T06:48:15.126Z - **Download time:** 762 ms - **Static scan time:** 21 ms - **AI review time:** 30129 ms - **Total time:** 30912 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 automatic install hook changes project agent rules so agents load and follow this package’s governance file as their highest-priority guidance. This is a first-party agent configuration setup with residual lifecycle risk. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** Subsequent agent sessions may follow package-provided instructions that affect how they handle project tasks. - **Evidence paths:** package.json, scripts/install-anchors.js, ai-engineering-specs/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-10-20T06:48:15.126Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes a package-named Cursor rule and inserts or refreshes a marked Kilo rules block that directs agents to the bundled governance file. - **Rationale:** Source confirms an automatic install-time setup that modifies project agent rules and promotes package-provided instructions. This matches first-party agent extension lifecycle risk; the inspected code does not establish a broader attack. - **Files touched:** .cursor/rules/mdd-ai-eng.mdc, .kilocoderrules ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package postinstall hook runs the anchor installer automatically., The installer creates or updates a project Cursor rule and inserts or replaces a marked block in the project Kilo rules file., The generated anchor directs agents to load the package’s bundled governance file and treat it as the highest-priority guidance., The bundled file itself says agents must treat it and its indexes as their highest action rules. - **Evidence against:** The writes are limited to a package-named Cursor rule and a marked Kilo block; the installer preserves content outside that block., The package describes this agent-configuration setup as its intended installation behavior. ## Affected versions and remediation This report applies to @mdd-ai-eng/specs@1.1.2. - Review the evidence and your use of @mdd-ai-eng/specs@1.1.2 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.
