It enables hooks and pre-trusts the Baize project, then installs a SessionStart hook configuration. - **Trigger:** npm install of this package after ~/baize/.claude exists and ~/.codex/config.toml or ~/.codex/auth.json exists - **Impact:** Changes a foreign global AI-agent control surface without an explicit CLI setup command, enabling package-managed agent hooks. - **Evidence paths:** package.json, scripts/postinstall.js, cli/lib/sync-settings-hooks.js, cli/lib/runtime-setup.js, cli/lib/codex-hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T06:28:26.266Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven global Codex trust and hook enablement - **Attack narrative:** Installing the package invokes postinstall. If a Baize directory is initialized and any Codex state exists, the install path refreshes Codex configuration without the user running \`baize init\`: it writes the global Codex config, enables hooks, marks the Baize project trusted, and installs SessionStart hooks. This is unconsented install-time mutation of a global AI-agent control surface. - **Rationale:** The source confirms a concrete postinstall chain that mutates global Codex trust and hook settings based solely on pre-existing state. This meets the install-control-surface block boundary despite the absence of credential exfiltration. - **Files touched:** ~/baize/.claude/settings.json, ~/baize/.codex/config.toml, ~/.codex/config.toml, ~/baize/.codex/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Manifest runs a postinstall script., Postinstall runs when ~/baize/.claude already exists., Postinstall sync targets Codex whenever Codex config or auth state exists., Sync writes ~/.codex/config.toml, enables hooks, and trusts the Baize project., The same write installs a SessionStart hook configuration. - **Evidence against:** No install-time network request or credential exfiltration was found., Credential verification endpoints are official Anthropic/OpenAI APIs and are reached only by explicit init flows. ## Public findings ### 1.
