The install changes agent behavior across the user's machine and activates package hooks in those environments. - **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:** 1.3.6 - **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. The automatic postinstall proceeds for global npm installs and mutates multiple user-level AI-agent control surfaces. This is unconsented broad agent configuration mutation during an install lifecycle, which meets the blocking policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-11T21:25:43.883Z - **Finished:** 2026-10-11T21:26:15.254Z - **Download time:** 1033 ms - **Static scan time:** 820 ms - **AI review time:** 29518 ms - **Total time:** 31371 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:** The npm postinstall runs machine setup on global installs. Setup writes Claude, OpenCode, and Codex agent integrations into user-level configuration, causing them to load twing hooks across sessions. - **Trigger:** A global npm install that runs the package postinstall. - **Impact:** The install changes agent behavior across the user's machine and activates package hooks in those environments. - **Evidence paths:** package.json, postinstall.cjs, dist/machine-setup.js, dist/resolve-hook.js, dist/opencode-plugin.js, dist/codex-hooks.js, dist/wire-hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T21:26:15.254Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script calls machine setup, which wires resolver hooks and agent plugins into user configuration without a separate consent check in the hook. - **Attack narrative:** A global npm install triggers postinstall setup, which wires twing into user-level Claude, OpenCode, and Codex configuration. This activates hooks across sessions on the machine. Ordinary non-global installs exit before setup, but the global install lifecycle itself has no separate consent gate for these agent configuration changes. - **Rationale:** The automatic postinstall proceeds for global npm installs and mutates multiple user-level AI-agent control surfaces. This is unconsented broad agent configuration mutation during an install lifecycle, which meets the blocking policy. - **Files touched:** postinstall.cjs, dist/machine-setup.js, dist/resolve-hook.js, dist/opencode-plugin.js, dist/codex-hooks.js, dist/wire-hooks.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The package postinstall automatically runs a setup script., The setup script proceeds on global npm installs and calls machine setup., Machine setup wires Claude, OpenCode, and Codex integrations and marks the machine as managed., The wiring functions write user-level agent configuration and install hook or plugin files. - **Evidence against:** The postinstall exits for installs that are not global and do not include the machine-setup flag., The package also exposes explicit onboarding commands for wiring agent integrations. ## Affected versions and remediation This report applies to @twing/cli@1.3.6. - Avoid installing @twing/cli@1.3.6. 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.
