Persists package-controlled command execution in the user's AI-agent control surface. - **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:** 0.11.0 - **Selected version is latest:** No - **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. LPM flags this version as an AI-agent control-surface risk. Installation modifies user-level Claude Code settings when Claude is detected. It registers a command hook that executes on future Claude sessions across projects. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T11:46:38.864Z - **Finished:** 2026-09-12T11:47:31.611Z - **Download time:** 777 ms - **Static scan time:** 188 ms - **AI review time:** 51781 ms - **Total time:** 52747 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 modifies user-level Claude Code settings when Claude is detected. It registers a command hook that executes on future Claude sessions across projects. - **Trigger:** npm postinstall - **Impact:** Persists package-controlled command execution in the user's AI-agent control surface. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T11:47:31.611Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global Claude SessionStart hook registration - **Attack narrative:** On npm installation, postinstall detects configured AI clients and installs the skill. For Claude Code it automatically writes a user-level SessionStart command hook, which invokes the package validator in future sessions on projects across the machine. This mutates a foreign, broad AI-agent control surface without an interactive consent step. - **Rationale:** This is an automatic postinstall mutation of user-level Claude configuration that establishes ongoing command execution. The behavior meets the install-control-surface block policy despite the absence of network exfiltration. - **Files touched:** package.json, scripts/postinstall.js, scripts/lib.js, ~/.claude/skills/mkt-agentic-sdlc, ~/.claude/settings.json, ~/.agentic-sdlc/orient-hook-wired ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs a postinstall script., Postinstall detects Claude Code, copies a skill, and invokes global hook wiring without asking., The hook writer adds a command SessionStart entry to user-level Claude settings., The global hook runs the package validator in future Claude sessions on every project. - **Evidence against:** No network or credential-exfiltration code was found in the inspected JavaScript sources., The separate init command is user-invoked, but the global hook wiring is automatic during installation. ## Affected versions and remediation This report applies to @antoneeo/mkt-agentic-sdlc-skill@0.11.0. - Avoid installing @antoneeo/mkt-agentic-sdlc-skill@0.11.0. 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.
