It establishes a Screenata instruction file and links/copies it into multiple third-party agent control surfaces. - **Trigger:** npm postinstall - **Impact:** Unconsented persistent agent-behavior modification across detected coding-agent installations. - **Evidence paths:** package.json, dist/postinstall.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T12:04:49.202Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent cross-agent skill installation and replacement - **Attack narrative:** Installing the package invokes dist/postinstall.js, which silently writes a Screenata skill and installs it into every detected Claude Code, Codex, OpenCode, and OpenClaw skill directory. The installer can unlink an existing file at those paths before creating a symlink or copy, creating persistent cross-agent control-surface changes without an explicit CLI command or consent. - **Rationale:** The package performs unconsented postinstall mutation of broad foreign AI-agent control surfaces. This meets the firewall block boundary even though no install-time exfiltration was found. - **Files touched:** package.json, dist/postinstall.js, ~/.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 runs dist/postinstall.js during postinstall., dist/postinstall.js immediately calls runInitSilent()., It writes ~/.agents/skills/screenata/SKILL.md without user action., It detects and installs/symlinks into Claude, Codex, OpenCode, and OpenClaw skill directories., Existing target skill files may be unlinked and replaced. - **Evidence against:** No install-time network request or credential collection appears in dist/postinstall.js., CLI API/token handling is runtime command functionality, not used by postinstall. ## Public findings ### 1.
