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. LPM treats this as warn-only first-party agent extension lifecycle risk. On npm installation, the package silently creates or replaces its Screenata skill in detected AI coding-agent directories. No install-time network or credential-exfiltration behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T19:59:11.864Z - **Finished:** 2026-09-12T20:00:08.302Z - **Download time:** 760 ms - **Static scan time:** 3525 ms - **AI review time:** 52153 ms - **Total time:** 56438 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:** On npm installation, the package silently creates or replaces its Screenata skill in detected AI coding-agent directories. No install-time network or credential-exfiltration behavior was found. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** The package can alter instructions available to multiple installed coding agents without an explicit user command. - **Evidence paths:** package.json, dist/postinstall.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T20:00:08.302Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installation of a bundled AI-agent skill into user-home agent directories. - **Rationale:** This is a first-party agent-extension lifecycle risk rather than confirmed malware: it silently modifies multiple agent skill directories at install time. The absence of exfiltration, remote execution, and a self-dependency chain supports a warning instead of a block. - **Files touched:** .agents/skills/screenata/SKILL.md, .claude/skills/screenata/SKILL.md, .codex/skills/screenata/SKILL.md, .config/opencode/skills/screenata/SKILL.md, .openclaw/skills/screenata/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package runs code automatically after installation., The install hook silently installs a bundled Screenata skill., It writes into detected Claude, Codex, OpenCode, and OpenClaw skill directories without an explicit command. - **Evidence against:** The install hook contains no network request or credential collection., The package has no runtime dependencies, so there is no nested self-dependency lifecycle chain., The other package-manager invocation is an interactive CLI upgrade path, not install-time code. ## Affected versions and remediation This report applies to @screenata/cli@0.5.7. - Review the evidence and your use of @screenata/cli@0.5.7 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.
