The package gains persistent behavior-bearing integrations in Claude, Codex, and Antigravity user configuration. - **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:** 1.11.0 - **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 installation triggers automatic deployment of this package's AI-agent integrations. It modifies user-home agent control surfaces without a separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T12:02:39.340Z - **Finished:** 2026-09-12T12:03:29.456Z - **Download time:** 765 ms - **Static scan time:** 522 ms - **AI review time:** 48828 ms - **Total time:** 50116 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A global npm installation triggers automatic deployment of this package's AI-agent integrations. It modifies user-home agent control surfaces without a separate setup command. - **Trigger:** Global npm installation, or setting COSMO\_POSTINSTALL\_FORCE=1 during installation. - **Impact:** The package gains persistent behavior-bearing integrations in Claude, Codex, and Antigravity user configuration. - **Evidence paths:** package.json, scripts/postinstall.mjs, packages/cli/lib/agent-adapters.mjs, packages/cli/lib/claude-plugin.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T12:03:29.456Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies and replaces agent skills, workflows, plugins, and a launcher. - **Attack narrative:** Installing the package globally invokes postinstall. That script iterates over all supported agents with replacement enabled and validation disabled. The adapters copy package-controlled skill and workflow content into user-home Codex and Antigravity locations, while the Claude path copies a plugin and writes an executable launcher. This is automatic lifecycle mutation of multiple foreign AI-agent control surfaces, rather than an explicit user setup action. - **Rationale:** The package has a concrete postinstall path that automatically persists integrations across three AI-agent environments on global installation. This meets the install-hook abuse policy even though no lifecycle network exfiltration was found. - **Files touched:** scripts/postinstall.mjs, packages/cli/lib/agent-adapters.mjs, packages/cli/lib/claude-plugin.mjs, ~/.agents/skills/cosmo, ~/.gemini/config/global\_workflows/cosmo.md, ~/.claude/skills/cosmo ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall lifecycle script., On global installation, postinstall automatically installs integrations for Claude, Codex, and Antigravity., The installer replaces package-owned agent skill directories and writes a global Antigravity workflow., The Claude installer copies a plugin and writes an executable launcher into the user's Claude skills directory. - **Evidence against:** The lifecycle path makes no network request or shell invocation., The CLI also exposes explicit agent-install commands, but postinstall bypasses those commands on global installs. ## Affected versions and remediation This report applies to @archangel70/cosmo@1.11.0. - Avoid installing @archangel70/cosmo@1.11.0. 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.
