Future Claude sessions can automatically execute package-controlled code, and supported agent clients receive global package content. - **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:** 0.10.0 - **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. Installing the package can alter global AI-agent skill directories and Claude user settings without an interactive choice. It persists a SessionStart command hook that later runs the installed validator. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T10:10:16.144Z - **Finished:** 2026-09-13T10:11:07.581Z - **Download time:** 766 ms - **Static scan time:** 188 ms - **AI review time:** 50481 ms - **Total time:** 51437 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:** Installing the package can alter global AI-agent skill directories and Claude user settings without an interactive choice. It persists a SessionStart command hook that later runs the installed validator. - **Trigger:** npm postinstall when a supported AI client is detected and Python is available - **Impact:** Future Claude sessions can automatically execute package-controlled code, and supported agent clients receive global package content. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T10:11:07.581Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global skill installation and user-level SessionStart hook injection - **Attack narrative:** The postinstall lifecycle script detects AI clients, copies the package skill into their global directories, and for Claude calls a helper that adds a command-type SessionStart hook to the user-level settings file. The hook invokes the package-installed Python validator on later agent sessions. This is automatic mutation of a broad, foreign AI-agent control surface; the package explicitly performs it without asking during installation. - **Rationale:** The package has a concrete automatic postinstall path that modifies global AI-agent configuration and establishes future command execution. This meets the install-time AI-agent control-hijack boundary even though no exfiltration or network behavior was found. - **Files touched:** ~/.claude/settings.json, ~/.claude/skills/mkt-agentic-sdlc, ~/.gemini/skills/mkt-agentic-sdlc, ~/.codex/skills/mkt-agentic-sdlc, ~/.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 manifest automatically runs postinstall., Postinstall detects installed AI clients and copies this skill into their global skill directories., On detecting Claude, postinstall automatically adds a machine-global SessionStart command hook., The hook is written to the user-level Claude settings and executes the installed Python validator in future sessions. - **Evidence against:** No network endpoints or credential collection were found in the inspected lifecycle code., The preuninstall hook removes only skill directories and attributable hooks. ## Affected versions and remediation This report applies to @antoneeo/mkt-agentic-sdlc-skill@0.10.0. - Avoid installing @antoneeo/mkt-agentic-sdlc-skill@0.10.0. 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.
