It installs a skill that directs agents to route work through llm-relay and configures Codex child agents to use it. - **Trigger:** Installing llm-relay globally, or its automatic global updater reinstalling a newer release. - **Impact:** Future Claude Code, Codex, and OpenCode agent behavior can be redirected to the package's relay without an explicit setup command from the user. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T00:17:56.062Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall AI-agent configuration and prompt injection through installed skills. - **Attack narrative:** The postinstall hook runs on a global installation and writes into Claude Code, Codex, and OpenCode configuration locations. It adds a Codex provider and a default child-agent profile that route work to llm-relay, then installs a skill instructing agents to offload work without operator approval. When used later, its update logic can reinstall a newer global package, repeating the lifecycle mutation. - **Rationale:** This is unconsented postinstall mutation of foreign AI-agent control surfaces, including a default Codex agent, combined with installed instructions that influence agent decisions. The global-install guard narrows exposure but does not provide 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:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Its npm postinstall automatically launches an installer., On global installation, the installer appends a Codex provider and creates a default agent that routes child work through this package., The same lifecycle script installs its skill into Claude Code, Codex, and OpenCode directories., The installed skill tells AI agents to offload work without waiting for the operator to ask., A runtime update path fetches the latest release and globally reinstalls the package automatically., Installer comments invoke adversarial review while defending automatic configuration changes. - **Evidence against:** The lifecycle installer exits for ordinary local installs unless forced., It does not overwrite an existing same-named Codex agent file., The inspected credential and proxy code did not show a concrete secret-exfiltration endpoint. ## Public findings ### 1.
