It can add a provider that routes Codex child agents through the package's loopback proxy. - **Trigger:** npm global installation runs postinstall. - **Impact:** Changes Claude Code, Codex, and OpenCode control surfaces without an explicit setup command; Codex child-agent traffic can be directed to the relay. - **Evidence paths:** package.json, scripts/install-skill.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T03:19:18.002Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-host AI-agent skill and configuration injection. - **Attack narrative:** Installing this package globally invokes postinstall without a separate setup command. The installer creates or overwrites package-owned skill files in Claude Code, Codex, and OpenCode directories, then writes a Codex provider pointing at the relay and creates relay-backed child-agent definitions. It attempts this whenever Codex is on PATH and deliberately proceeds if detection errors. This is an automatic mutation of foreign AI-agent control surfaces. - **Rationale:** The lifecycle hook performs automatic, cross-host AI-agent configuration changes and routes Codex agents through the package relay. The global-install guard does not establish explicit consent for these mutations, and the detector-failure path still provisions Codex. - **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 npm postinstall hook automatically runs the host-setup script., On global installation, the script copies a package skill into Claude Code, Codex, and OpenCode directories., The same automatic script adds a loopback relay provider and relay-backed agents to Codex configuration., If Codex detection fails, the script provisions Codex anyway. - **Evidence against:** Repo-local installs exit before host-directory changes., No credential exfiltration or non-loopback endpoint was established in the inspected lifecycle code. ## Public findings ### 1.
