The project Claude skill surface is rewritten during install, so later agent sessions follow this package's instructions without a separate setup command. - **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:** 3.3.0 - **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. npm install runs postinstall.mjs, which deletes and recopies bundled Claude skill files into the consumer project's .claude/skills directory. The skill widens when the coding agent should follow this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-22T16:17:39.707Z - **Finished:** 2026-09-22T16:18:59.780Z - **Download time:** 1013 ms - **Static scan time:** 1530 ms - **AI review time:** 77529 ms - **Total time:** 80073 ms The recorded confidence comes from the underlying analysis.

The skill widens when the coding agent should follow this package. - **Trigger:** npm install lifecycle postinstall - **Impact:** The project Claude skill surface is rewritten during install, so later agent sessions follow this package's instructions without a separate setup command. - **Evidence paths:** package.json, postinstall.mjs, agents/claude/evoke-astro-core/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-22T16:18:59.780Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script resolves the consumer project root, removes each destination skill directory, and copies agents/claude into .claude/skills. The installed skill instructs the agent to activate on generic interface requests. - **Attack narrative:** On npm install, postinstall.mjs walks three directories up from the package and treats that location as the consumer project. It deletes each skill directory under .claude/skills that matches the bundled agents/claude tree, then copies those skills into place. The installed skill tells Claude to use this library for carousels, modals, tabs, PDF viewers, and similar requests even when the user never names the package. Install therefore rewrites the project's agent control surface. - **Rationale:** The postinstall hook unconditionally replaces directories in the consumer project's .claude/skills with a package-supplied Claude skill that auto-triggers on generic UI requests. That is an unconsented install-time write to a foreign agent control surface. - **Files touched:** .claude/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json registers an npm postinstall script that runs node postinstall.mjs., postinstall.mjs walks up to the consumer project, deletes matching directories under .claude/skills, and copies agents/claude into that directory., The copied skill tells Claude to consult it for generic UI work even when the user never names the package. - **Evidence against:** The skill body is component and integration documentation., No credential harvesting, outbound exfiltration, eval, or shell execution appears in the install path., The package does not depend on its own name at runtime. ## Affected versions and remediation This report applies to @inizioevoke/astro-core@3.3.0. - Avoid installing @inizioevoke/astro-core@3.3.0. 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.
