It registers a command hook that runs on every SessionStart. - **Trigger:** npm postinstall when Claude Code is detected and Python is available. - **Impact:** A package-controlled command is added to a broad user AI-agent control surface without an explicit setup command or prompt. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:17:51.849Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent SessionStart hook installation. - **Attack narrative:** The npm postinstall script detects Claude Code, copies the skill into the user profile, and invokes code that creates or changes the user-level settings file. That code appends a SessionStart command pointing to the installed validator, causing package-controlled code to run whenever Claude starts across projects. The hook is installed automatically and the package explicitly bypasses an interactive consent step. - **Rationale:** The package has a concrete automatic postinstall chain that mutates a broad AI-agent control surface and registers persistent session-start execution. This meets the install-hook abuse blocking policy despite no observed network exfiltration. - **Files touched:** 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 block:** The automatic postinstall hook runs package code during npm installation., Postinstall detects Claude Code, installs files into its user skill directory, and wires a hook without asking., The hook modifies the user-level Claude settings to run a package validator at every SessionStart. - **Evidence against:** No network endpoint or credential-exfiltration code was found in the inspected lifecycle path., The installed hook targets the package's local validator rather than a remote payload. ## Affected versions and remediation This report applies to @antoneeo/mkt-agentic-sdlc-skill@0.8.0. - Avoid installing @antoneeo/mkt-agentic-sdlc-skill@0.8.0. 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.
