A package installation can cause Claude to automatically apply package-authored instructions during later development work. - **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:** 1.9.8 - **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. An automatic install hook changes the consumer project's Claude agent control surface. No network attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-28T06:56:55.398Z - **Finished:** 2026-09-28T06:57:46.477Z - **Download time:** 768 ms - **Static scan time:** 882 ms - **AI review time:** 49428 ms - **Total time:** 51079 ms The recorded confidence comes from the underlying analysis.

No network attack was identified. - **Trigger:** Installing the package through npm with lifecycle scripts enabled. - **Impact:** A package installation can cause Claude to automatically apply package-authored instructions during later development work. - **Evidence paths:** package.json, scripts/setup.mjs, templates/ui-mapping-skill.md - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:57:46.477Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script copies a package-controlled skill into .claude/skills and also modifies an ESLint configuration when present. - **Attack narrative:** Installing the package automatically launches its setup script. That script writes a package-controlled Claude skill into the consuming project and invokes the operation during postinstall, rather than only after an explicit setup command. The injected skill is configured to activate for broad, ordinary UI development tasks. This is an unconsented lifecycle mutation of a foreign AI-agent control surface. - **Rationale:** The package performs an automatic postinstall write to a consumer project's .claude skill directory. This concrete AI-agent control-surface mutation meets the publish-block policy. - **Files touched:** .claude/skills/impakers-ui-mapping/SKILL.md, eslint.config.mjs, eslint.config.js, eslint.config.cjs ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs scripts/setup.mjs automatically through an npm postinstall hook., The setup script writes a managed skill into the consumer project's .claude/skills directory., The postinstall path invokes the skill installer without an interactive consent step., The injected skill declares automatic activation across common UI-editing work. - **Evidence against:** The installer avoids overwriting an existing skill that lacks its managed marker., The script limits its ESLint change to a detected configuration file and validates syntax. ## Affected versions and remediation This report applies to @impakers/debug@1.9.8. - Avoid installing @impakers/debug@1.9.8. 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.
