The package gains recurring execution in the user's Claude agent sessions and changes a broad user-level agent control surface without an explicit 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:** 0.12.0 - **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 automatically modifies detected AI-agent skill directories and Claude's user-level settings. It registers a SessionStart command that runs the installed validator for future Claude sessions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T05:43:22.908Z - **Finished:** 2026-09-14T05:44:35.042Z - **Download time:** 504 ms - **Static scan time:** 236 ms - **AI review time:** 71393 ms - **Total time:** 72134 ms The recorded confidence comes from the underlying analysis.

It registers a SessionStart command that runs the installed validator for future Claude sessions. - **Trigger:** npm postinstall when a supported client is detected and Python is available - **Impact:** The package gains recurring execution in the user's Claude agent sessions and changes a broad user-level agent control surface without an explicit setup action. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:44:35.042Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent skill installation and SessionStart hook registration - **Attack narrative:** The package declares postinstall, so npm invokes its installer automatically. The installer detects installed AI clients and copies the skill into their user-level directories. For Claude, it calls the global hook writer, which appends a command hook to the user's settings.json. That hook runs the package-installed Python validator on every SessionStart. This is an unconsented postinstall mutation of a broad AI-agent control surface, even though the inspected payload is local and no network exfiltration was found. - **Rationale:** The package performs automatic postinstall mutation of a user-level Claude SessionStart control surface, creating recurring agent-session execution. This meets the install-hook abuse blocking policy despite the absence of observed network theft. - **Files touched:** scripts/postinstall.js, scripts/lib.js, ~/.claude/skills/mkt-agentic-sdlc, ~/.claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The automatic postinstall hook runs the installer without an explicit setup command., Postinstall detects AI clients, copies the skill into their home directories, and automatically wires Claude's global session hook., The global hook writes a command into the user's Claude settings, causing package code to run at every Claude session start., The installer calls global hook wiring when it detects an installed Claude client., Global wiring adds a command hook to Claude’s SessionStart settings. - **Evidence against:** No network endpoint, credential collection, or data-exfiltration code was found in the inspected sources., The hook command invokes the package's local validator and uninstall removes attributable hooks. ## Affected versions and remediation This report applies to @antoneeo/mkt-agentic-sdlc-skill@0.12.0. - Avoid installing @antoneeo/mkt-agentic-sdlc-skill@0.12.0. 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.
