Package-authored instructions become available to Claude, Codex, and shared agent runtimes 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:** 2.0.1 - **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. A global npm postinstall writes package-controlled skill files into three AI-agent control surfaces. CLI startup also restores or updates those files automatically. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T23:40:30.412Z - **Finished:** 2026-09-11T23:41:15.389Z - **Download time:** 510 ms - **Static scan time:** 151 ms - **AI review time:** 44315 ms - **Total time:** 44977 ms The recorded confidence comes from the underlying analysis.

CLI startup also restores or updates those files automatically. - **Trigger:** Global package installation or any invocation of the rplay CLI. - **Impact:** Package-authored instructions become available to Claude, Codex, and shared agent runtimes without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, src/skill.js, src/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T23:41:15.389Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent skill installation and refresh. - **Attack narrative:** Installing this package globally runs its postinstall hook, which creates and writes skill files under the user’s Claude, Codex, and shared agent directories. Separately, every CLI run checks whether those skills are current and reinstalls them when needed. This is an unconsented lifecycle mutation of broad AI-agent control surfaces. - **Rationale:** The package automatically persists package-controlled instructions into multiple unrelated AI-agent skill directories during installation and runtime. The opt-out does not make this an explicit user-command setup. - **Files touched:** ~/.claude/skills/rplay/SKILL.md, ~/.claude/skills/rplay/AI.md, ~/.codex/skills/rplay/SKILL.md, ~/.codex/skills/rplay/AI.md, ~/.agents/skills/rplay/SKILL.md, ~/.agents/skills/rplay/AI.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., On global installation, that hook installs a skill without a user command., The installer writes package-controlled instructions into Claude, Codex, and shared agent skill directories., Every CLI invocation repeats the installation when a skill is absent or stale. - **Evidence against:** The install hook skips local installs, CI, and an opt-out environment setting., No source evidence shows credential harvesting or unrelated network exfiltration. ## Affected versions and remediation This report applies to rplay-cli@2.0.1. - Avoid installing rplay-cli@2.0.1. 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.
