A failed host-detection path still provisions Codex. - **Trigger:** Installing llm-relay globally through npm, which runs postinstall. - **Impact:** The package can redirect Codex child agents to its loopback relay and alter multiple AI-agent control surfaces without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T20:02:42.006Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of AI-agent skill and configuration files. - **Attack narrative:** The package registers a postinstall hook that runs automatically for global npm installs. That hook copies skills into Claude Code, Codex, and OpenCode directories, appends a Codex provider that routes to the package's loopback service, and creates Codex agent definitions. Its error path intentionally proceeds with Codex provisioning when detection is unavailable. This is an unconsented install-time modification of external AI-agent control surfaces. - **Rationale:** The automatic global postinstall mutates foreign AI-agent configuration and persists a provider and child agents. The global-install guard does not establish explicit consent for these changes. - **Files touched:** ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/skills/llm-relay/SKILL.md, ~/.config/opencode/skills/llm-relay/SKILL.md, ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.codex/agents/relay\_coding.toml - **Network endpoints:** 127.0.0.1:8791 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically runs an installer., On global installation, the installer copies a bundled skill into Claude Code, Codex, and OpenCode configuration areas., The installer adds a Codex model provider and writes default and relay\_coding agent definitions., If Codex detection fails, the installer deliberately provisions Codex anyway. - **Evidence against:** The installer skips ordinary local installs unless manually forced., The configured provider points to the local loopback relay, not an external host. ## Public findings ### 1.
