It creates or replaces agent skill files without an explicit user command. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** Persistent alteration of Claude, Codex, OpenCode, or OpenClaw instruction/control surfaces. - **Evidence paths:** package.json, dist/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T01:00:29.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes and symlinks/copies a packaged skill into detected AI-agent skill directories - **Attack narrative:** On installation, the package runs its bundled postinstall code. That code detects several unrelated AI-agent installations, creates a canonical Screenata skill under the user's home directory, then symlinks or copies it into each detected agent's skill directory. This occurs without an explicit \`screenata init\` command or user approval, persistently influencing future agent behavior. - **Rationale:** The package performs unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the install-control-surface block policy even though no install-time network exfiltration was found. - **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:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall imports and executes the installer., Installer targets detected Claude, Codex, OpenCode, and OpenClaw skill directories., Install-time code writes a canonical skill then symlinks or copies it into agent control surfaces., The postinstall entry unconditionally calls the silent installer. - **Evidence against:** No network request is present in the postinstall bundle., CLI API traffic appears runtime/user-command functionality, not postinstall behavior. ## Public findings ### 1.
