It also configures Codex children to use the package's loopback provider. - **Trigger:** Installing llm-relay globally runs postinstall. - **Impact:** Future AI sessions can receive instructions to route or offload work without an operator request, and Codex child-agent behavior is changed. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/claude-hook.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T21:48:04.895Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time AI-agent skill injection and Codex provider configuration. - **Attack narrative:** The global postinstall hook copies a package-authored skill into Claude Code, Codex, and OpenCode directories, then adds a Codex provider and default child agent. The injected skill tells AI hosts to offload work without waiting for the operator. The package also contains functionality that installs a Claude hook which denies Agent calls and returns a relay command. These are persistent modifications to foreign AI-agent control surfaces rather than necessary local proxy setup. - **Rationale:** This package automatically changes foreign AI-agent instruction and configuration surfaces during global installation, and its injected instructions explicitly remove operator consent from offloading decisions. The local-install guard does not neutralize the global postinstall behavior. - **Files touched:** scripts/install-skill.mjs, skills/llm-relay/SKILL.md, ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/skills/llm-relay/SKILL.md, ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.config/opencode/skills/llm-relay/SKILL.md - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs an install hook that invokes its skill installer., On global installation, the installer copies a package-controlled skill into Claude Code, Codex, and OpenCode configuration directories., The install hook adds a new Codex provider and creates a replacement default child-agent definition., The installed skill tells an AI host to offload work without the operator asking first., The bundled skill documents adding a Claude PreToolUse hook that can deny agent calls. - **Evidence against:** A non-global install exits before modifying host skill directories., The manifest has no dependency on another release of llm-relay., The hook-installing CLI command is user-invoked, but the global install-time skill and Codex mutations are automatic. ## Public findings ### 1.
