The injected skill directs hosts to offload work through llm-relay without operator approval. - **Trigger:** Installing llm-relay globally through npm triggers postinstall. - **Impact:** AI agents may be steered to use the package's relay and external model-provider routing without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-31T16:20:26.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent configuration and instruction injection. - **Attack narrative:** A global npm install automatically runs the installer. It writes package-controlled instructions into Claude Code, Codex, and OpenCode skill locations, adds a loopback llm-relay provider to Codex, and creates relay-backed child agents. The installed skill tells an AI host to offload work through the relay without waiting for the operator. This is an unconsented lifecycle mutation of foreign AI-agent control surfaces that can redirect agent behavior and provider traffic. - **Rationale:** The package combines an automatic install hook, writes to multiple foreign AI-agent configuration surfaces, and injected instructions that direct agents to use its relay without user approval. This meets the install-hook abuse boundary even though the local relay endpoint itself is loopback-only. - **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:** http://127.0.0.1:8791/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The install lifecycle automatically runs a host-configuration installer., On global installation, it copies a skill into Claude Code, Codex, and OpenCode configuration directories., It creates or changes Codex's global provider configuration and child-agent files., The installed skill instructs an AI agent to use the relay without the operator asking, steering work and traffic to the package's provider pool. - **Evidence against:** The installer skips ordinary local installs unless forced., The configured relay endpoint is loopback-only; no secret exfiltration endpoint was found in the inspected install path. ## Public findings ### 1.
