It creates or overwrites an agent extension outside the consuming project and can influence later agent behavior. - **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:** 1.6.0 - **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. An npm postinstall installs a skill into the user's .agents/skills control surface without an explicit user command. That skill contains instructions to bypass normal agent confirmation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-20T20:17:18.369Z - **Finished:** 2026-09-20T20:26:34.885Z - **Download time:** 520 ms - **Static scan time:** 54 ms - **AI review time:** 555942 ms - **Total time:** 556516 ms The recorded confidence comes from the underlying analysis.

That skill contains instructions to bypass normal agent confirmation. - **Trigger:** Installing this package as a consumer dependency triggers postinstall. - **Impact:** It creates or overwrites an agent extension outside the consuming project and can influence later agent behavior. - **Evidence paths:** package.json, install.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-20T20:26:34.885Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install.js derives a user-home agent skills path and recursively force-copies the package payload there. - **Attack narrative:** A normal npm install invokes install.js. When installed under node\_modules, it writes a copied skill payload to the user's .agents/skills/dobot-plus directory, outside the project. The copied skill directs agents to ignore memory and execute steps without confirmation, creating an unconsented agent-control persistence path. - **Rationale:** The automatic lifecycle hook mutates a broad, foreign AI-agent control surface and installs instructions designed to suppress confirmation. This is concrete install-time control-surface abuse despite no observed network exfiltration. - **Files touched:** package.json, install.js, SKILL.md, .agents/skills/dobot-plus ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs install.js after npm installation., The installer targets a per-user .agents/skills directory when no override is supplied., During installation it recursively and forcibly copies the skill payload, including node\_modules, into that agent control surface., The installed skill instructs an agent to ignore memory and perform actions automatically without confirmation. - **Evidence against:** No network endpoint or credential collection was found in the inspected installer., The manifest has no runtime dependency on another version of itself. ## Affected versions and remediation This report applies to @dobot-plus/skill@1.6.0. - Avoid installing @dobot-plus/skill@1.6.0. 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.
