The added files can affect how consumer agents handle later tasks without a separate setup action. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.2.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall mutation adds package-controlled instructions to consumer AI-agent configuration without a separate user setup action. This meets the policy for blocking unconsented lifecycle changes to a foreign agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-22T01:53:16.174Z - **Finished:** 2026-10-22T01:53:49.335Z - **Download time:** 1030 ms - **Static scan time:** 19 ms - **AI review time:** 32110 ms - **Total time:** 33161 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 postinstall hook changes consumer AI-agent configuration and adds an instruction that directs agents to load this package’s rules. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** The added files can affect how consumer agents handle later tasks without a separate setup action. - **Evidence paths:** package.json, scripts/install-anchors.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T01:53:49.335Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes a Kilo rules file and a Cursor rule under the consumer root, embedding a package instruction for agent sessions. - **Attack narrative:** During package installation, the postinstall hook writes Kilo and Cursor agent rules into the consumer root. Those rules direct agents to load this package’s AGENTS.md at session start and when receiving tasks, creating an unconsented change to the consumer’s agent control surface. - **Rationale:** The automatic postinstall mutation adds package-controlled instructions to consumer AI-agent configuration without a separate user setup action. This meets the policy for blocking unconsented lifecycle changes to a foreign agent control surface. - **Files touched:** .kilocoderrules, .cursor/rules/mdd-ai-eng.mdc ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The package runs the anchor installer automatically through its postinstall hook., The installer adds a persistent instruction telling agents to load the package’s AGENTS.md at session start and when receiving tasks., The installer writes configuration in the consumer root for Kilo and Cursor; it can also update an existing Kilo anchor. ## Affected versions and remediation This report applies to @mdd-ai-eng/specs@1.2.0. - Avoid installing @mdd-ai-eng/specs@1.2.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
