The package can persist package-authored instructions in a foreign AI-agent control surface and alter project tooling configuration. - **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:** 1.9.7 - **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 the consumer project's Claude agent configuration and may modify its ESLint configuration. These changes occur without a separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T05:40:43.381Z - **Finished:** 2026-09-13T05:41:39.111Z - **Download time:** 1021 ms - **Static scan time:** 811 ms - **AI review time:** 53898 ms - **Total time:** 55730 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically changes the consumer project's Claude agent configuration and may modify its ESLint configuration. These changes occur without a separate setup command. - **Trigger:** npm installation runs the postinstall lifecycle script. - **Impact:** The package can persist package-authored instructions in a foreign AI-agent control surface and alter project tooling configuration. - **Evidence paths:** package.json, scripts/setup.mjs, templates/ui-mapping-skill.md - **Review source:** ai\_review - **Reviewed:** 2026-09-13T05:41:39.111Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic consumer-project agent-skill installation and configuration rewriting. - **Attack narrative:** On installation, package.json invokes scripts/setup.mjs. The script resolves the consumer project root, writes a managed SKILL.md under .claude/skills, and calls installEslintPreset to patch a supported JavaScript ESLint config. The injected skill directs AI debugging agents' behavior. This is automatic lifecycle-time mutation of a consumer-controlled AI-agent surface, not an explicit user setup action. - **Rationale:** The automatic postinstall writes a Claude skill into the consuming project and can rewrite its ESLint configuration. This is unconsented install-time mutation of a foreign AI-agent control surface and consumer project files. - **Files touched:** .claude/skills/impakers-ui-mapping/SKILL.md, eslint.config.mjs, eslint.config.js, eslint.config.cjs ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs its setup script during npm postinstall., The install script creates or updates a Claude skill inside the consumer project., The install script also rewrites a consumer ESLint configuration to import its preset., The bundled skill is an agent-targeted instruction file and states that npm installation updates it. - **Evidence against:** The installer has guards and an environment-variable opt-out., The inspected installer does not send data over the network or fetch remote code. ## Affected versions and remediation This report applies to @impakers/debug@1.9.7. - Avoid installing @impakers/debug@1.9.7. 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.
