Unconsented mutation of AI-agent control surfaces can alter future agent behavior. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.5.2 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package silently deploys a Screenata skill into detected third-party AI-agent skill directories. It can replace an existing SKILL.md at those locations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-13T07:53:29.323Z - **Finished:** 2026-08-13T07:54:38.113Z - **Download time:** 510 ms - **Static scan time:** 4502 ms - **AI review time:** 63776 ms - **Total time:** 68790 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package silently deploys a Screenata skill into detected third-party AI-agent skill directories. It can replace an existing SKILL.md at those locations. - **Trigger:** npm postinstall - **Impact:** Unconsented mutation of AI-agent control surfaces can alter future agent behavior. - **Evidence paths:** package.json, dist/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T07:54:38.113Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-agent skill installation and overwrite - **Attack narrative:** On installation, the lifecycle hook imports dist/postinstall.js. That artifact detects several unrelated AI-agent installations, writes a canonical skill, deletes an existing same-named skill file where present, and symlinks or copies its own SKILL.md into each detected agent directory. This occurs through runInitSilent without an explicit user command or consent. - **Rationale:** The package has a concrete, unconsented postinstall chain that mutates multiple foreign AI-agent control surfaces and may overwrite existing skill files. This meets the blocking policy regardless of the otherwise package-aligned runtime API client. - **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:** package.json executes dist/postinstall.js on install., Postinstall detects Claude, Codex, OpenCode, and OpenClaw skill locations., Installer removes an existing skill file, then symlinks or copies its own content., Postinstall silently installs the skill into every detected agent. - **Evidence against:** No network or credential handling was found in the postinstall artifact., The API client and token storage are CLI runtime behavior, not invoked by postinstall. ## Public findings ### 1.
