It installs skills and configures Codex to route agent traffic through the relay. - **Trigger:** Installing llm-relay globally through npm. - **Impact:** Changes AI-agent behavior and routing without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-30T22:52:36.040Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes cross-product AI-agent skills, provider configuration, and agent definitions. - **Attack narrative:** The postinstall hook invokes the installer. On global installs, it writes package-controlled skill files into three AI-agent products and modifies Codex configuration to use the llm-relay provider, while adding two agent profiles. The action occurs as part of npm lifecycle processing rather than through a separate user setup command. - **Rationale:** The source establishes automatic postinstall mutation of broad, foreign AI-agent control surfaces. The global-install guard and loopback endpoint reduce scope but do not provide consent for these configuration changes. - **Files touched:** ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/skills/llm-relay/SKILL.md, ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.codex/agents/relay\_coding.toml, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay/SKILL.md - **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 package runs an installer automatically in its postinstall hook., On global installation, the installer copies its skill into Claude Code, Codex, and OpenCode configuration locations., The installer adds a Codex model provider pointing at the package’s local relay and creates two Codex agent definitions., This is automatic lifecycle mutation of multiple foreign AI-agent control surfaces, not an explicit setup command. - **Evidence against:** Local installs exit without changing host skill directories., Codex provider setup is gated on detecting the Codex executable., The configured provider endpoint is loopback, and the inspected installer contains no credential-exfiltration request. ## Public findings ### 1.
