Later mutating CLI invocations can automatically reinstall the latest package release, repeating that lifecycle mutation. - **Trigger:** Global installation, or a mutating llm-relay CLI command when a newer release is available. - **Impact:** It can steer Claude, Codex, and OpenCode agent behavior and route Codex child-agent requests through the package's loopback relay without separate user setup. - **Evidence paths:** package.json, scripts/install-skill.mjs, dist/self-update.js, dist/cli.js, skills/llm-relay/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-31T16:50:28.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-host skill and provider configuration injection with self-updating global reinstall. - **Attack narrative:** Installing this package globally runs postinstall, which copies an instruction-bearing skill into multiple AI-agent host directories and changes Codex provider and child-agent configuration. The injected skill directs agents to offload work through llm-relay without asking. When users run mutating CLI commands, the package checks the npm registry and can install the newest global release automatically, causing the lifecycle installer to run again. This is an unconsented automatic mutation of foreign AI-agent control surfaces. - **Rationale:** The package combines an automatic lifecycle hook, broad host-agent configuration writes, injected agent instructions, and runtime self-updating through a fresh global install. The global-install guard narrows when it occurs but does not provide separate consent for these foreign control-surface mutations. - **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, 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook runs an installer., On global installs, the installer writes skills into Claude, Codex, and OpenCode host directories., The installer adds a llm-relay provider and two default-named Codex child agents., Mutating CLI commands automatically self-update by installing the latest global release, which reruns postinstall., The installed skill instructs AI hosts to use the relay before normal work without asking first. - **Evidence against:** The postinstall installer skips ordinary local installs unless forced., The installer preserves existing agent files with the same names. ## Public findings ### 1.
