Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 1.13.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package’s command installs bundled instructions into coding-agent skill folders, which is a concrete agent extension capability. Because this requires explicit command execution and no malicious behavior was established, classify it as suspicious and warn. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-12T19:58:58.736Z - **Finished:** 2026-10-12T20:00:20.122Z - **Download time:** 520 ms - **Static scan time:** 10 ms - **AI review time:** 80855 ms - **Total time:** 81386 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:** The command installs Vatio’s bundled skill instructions into project-level skill folders used by coding agents. This changes agent behavior, but the reviewed source does not establish a malicious attack. - **Trigger:** A user runs the vatio-skills command. - **Impact:** The installed instructions can affect how coding agents behave in that project. - **Evidence paths:** bin/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T20:00:20.122Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer recursively copies the bundled skills into .agents/skills and .claude/skills, replacing existing copies. - **Rationale:** The package’s command installs bundled instructions into coding-agent skill folders, which is a concrete agent extension capability. Because this requires explicit command execution and no malicious behavior was established, classify it as suspicious and warn. - **Files touched:** .agents/skills, .claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** High - **Evidence for warning:** The manifest exposes bin/install.mjs as a command and declares no npm lifecycle hooks., When run, the installer copies bundled skills into project-level .agents/skills and .claude/skills folders, overwriting existing copies., The session-sharing skill instructs the agent to ask the user before sending a session. - **Evidence against:** The agent-skill folder changes require an explicit command invocation; the inspected source does not show automatic install-time mutation., No malicious payload or hidden data transfer was identified in the reviewed installer. ## Affected versions and remediation This report applies to @vatio-ai/skills@1.13.0. - Review the evidence and your use of @vatio-ai/skills@1.13.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
