A global npm install mutates Claude/Codex skill and Codex provider-agent configuration. This is a guarded first-party extension setup, not a confirmed malware chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-08T22:18:06.606Z - **Finished:** 2026-08-08T22:18:40.306Z - **Download time:** 251 ms - **Static scan time:** 1189 ms - **AI review time:** 32259 ms - **Total time:** 33700 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install mutates Claude/Codex skill and Codex provider-agent configuration. This is a guarded first-party extension setup, not a confirmed malware chain. - **Trigger:** npm install -g llm-relay - **Impact:** Can alter default Codex child-agent routing to the local llm-relay service. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/claude-hook.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T22:18:40.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global postinstall provisions local AI-agent skills and relay-backed Codex profiles - **Rationale:** The package has an unconsented global AI-agent extension lifecycle action, warranting a warning under policy. Source inspection found no concrete exfiltration, remote-code, destructive, or stealth-persistence behavior supporting a block. - **Files touched:** skills/llm-relay/SKILL.md, ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/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:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Global postinstall copies skills into ~/.claude and ~/.codex., It appends an llm-relay provider to ~/.codex/config.toml., It creates default and relay\_coding Codex agent profiles., The shipped skill documents an explicit CLI-triggered Claude PreToolUse hook. - **Evidence against:** Postinstall exits without action for non-global installs., Install hook uses only bundled local files and a loopback 127.0.0.1 provider., No install-time network, credential harvesting, or remote payload execution found., Claude hook setup is invoked only by explicit offload commands, not postinstall. ## Public findings ### 1.
