Install-time code mutates detected AI-agent skill directories without an explicit user command. It installs a package-owned Screenata skill and may replace an existing skill of the same name. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 95.0% - **Started:** 2026-08-11T12:40:37.381Z - **Finished:** 2026-08-11T12:41:12.653Z - **Download time:** 510 ms - **Static scan time:** 4410 ms - **AI review time:** 30351 ms - **Total time:** 35272 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code mutates detected AI-agent skill directories without an explicit user command. It installs a package-owned Screenata skill and may replace an existing skill of the same name. - **Trigger:** npm postinstall - **Impact:** Changes AI-agent behavior for Screenata/compliance prompts in detected local agent installations. - **Evidence paths:** package.json, dist/postinstall.js, dist/cli.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T12:41:12.653Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent multi-agent skill installation via symlink or copied SKILL.md - **Rationale:** This is an unconsented install-time AI-agent extension setup, but source shows a bounded first-party skill rather than a concrete malware chain. The scanner's credential/network labels map to normal user-invoked CLI authentication and API operations. - **Files touched:** dist/postinstall.js, ~/.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:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs dist/postinstall.js during postinstall., dist/postinstall.js silently installs a Screenata SKILL into detected Claude, Codex, OpenCode, and OpenClaw directories., Installer replaces existing screenata SKILL.md files via unlink then symlink/copy. - **Evidence against:** Postinstall payload is embedded static skill text; no install-time network or payload fetch., Writes are limited to a named Screenata skill under detected agent skill directories., CLI API/OAuth traffic is user-command-driven and defaults to api.screenata.com. ## Public findings ### 1.
