The package gains automatic influence over future AI-agent sessions outside the consuming project. - **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:** 1.30.0 - **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 changes globally configured AI-agent skills. On detected Claude Code installations it also adds a user-level SessionStart command hook that invokes package code in later sessions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T05:17:09.684Z - **Finished:** 2026-09-14T05:17:55.840Z - **Download time:** 1029 ms - **Static scan time:** 185 ms - **AI review time:** 44941 ms - **Total time:** 46156 ms The recorded confidence comes from the underlying analysis.

On detected Claude Code installations it also adds a user-level SessionStart command hook that invokes package code in later sessions. - **Trigger:** npm installation or update on a machine where a supported AI client is detected. - **Impact:** The package gains automatic influence over future AI-agent sessions outside the consuming project. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:17:55.840Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies skills and writes a persistent Claude SessionStart command hook. - **Attack narrative:** During npm postinstall, the package detects installed AI clients and copies its skill into their global configuration directories. If Claude Code is detected, it writes a user-level SessionStart hook that calls the package validator on subsequent agent sessions. This is an unconsented install-time mutation of a broad AI-agent control surface; uninstall cleanup does not remove the initial installation-time risk. - **Rationale:** The package's automatic postinstall modifies global AI-agent configuration and establishes future command execution through Claude's SessionStart hook. This meets the install-hook abuse policy despite the absence of exfiltration or network activity. - **Files touched:** skills/agentic-sdlc-skill, ~/.claude/skills/agentic-sdlc, ~/.gemini/skills/agentic-sdlc, ~/.codex/skills/agentic-sdlc, ~/.claude/settings.json, ~/.agentic-sdlc/orient-hook-wired ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook runs automatically., Postinstall detects AI clients and copies a skill into their global skill directories., On detected Claude installations, postinstall adds a SessionStart command hook to user-level settings., The hook runs a package-supplied Python validator in future agent sessions and records a persistent marker. - **Evidence against:** No network endpoints or credential collection were found., The uninstall hook removes the package's attributed hook and copied skills. ## Affected versions and remediation This report applies to @antoneeo/agentic-sdlc-skill@1.30.0. - Avoid installing @antoneeo/agentic-sdlc-skill@1.30.0. 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.
