An install can alter AI-agent instruction surfaces in the user's home directory without an explicit setup command. - **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:** 0.5.6 - **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 creates and links or overwrites AI-agent skill files. It targets detected Claude Code, Codex, OpenCode, and OpenClaw installations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T00:43:10.102Z - **Finished:** 2026-09-13T00:44:02.418Z - **Download time:** 757 ms - **Static scan time:** 4007 ms - **AI review time:** 47551 ms - **Total time:** 52316 ms The recorded confidence comes from the underlying analysis.

It targets detected Claude Code, Codex, OpenCode, and OpenClaw installations. - **Trigger:** npm postinstall during package installation - **Impact:** An install can alter AI-agent instruction surfaces in the user's home directory without an explicit setup command. - **Evidence paths:** package.json, dist/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:44:02.418Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent cross-agent skill installation - **Attack narrative:** The package's postinstall hook imports dist/postinstall.js. That code detects multiple installed AI coding agents, creates a canonical skill file, then symlinks or copies it into each detected agent's skill directory. It executes silently during installation rather than through the documented init command, altering broad, third-party AI-agent control surfaces without consent. - **Rationale:** This is an unconsented install-time mutation of foreign AI-agent instruction directories. The lifecycle hook directly performs the change and suppresses errors, making it concrete install-hook abuse. - **Files touched:** ~/.agents/skills/screenata/SKILL.md, ~/.claude/skills/screenata/SKILL.md, $CODEX\_HOME/skills/screenata/SKILL.md, ~/.config/opencode/skills/screenata/SKILL.md, ~/.openclaw/skills/screenata/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically imports the installer., The installer detects several unrelated AI coding tools and writes a Screenata skill into their user-level skill directories., The install-time code silently invokes that installer, without a user command or consent prompt. - **Evidence against:** No network request or credential collection is performed by the postinstall bundle itself., The bundled CLI's platform API requests are activated by explicit CLI commands, not by the lifecycle hook. ## Affected versions and remediation This report applies to @screenata/cli@0.5.6. - Avoid installing @screenata/cli@0.5.6. 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.
