Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. A global npm install automatically installs skills into three AI-agent host directories and modifies Codex's provider and MCP configuration. Later mutating CLI use can check the registry and globally install a newer release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-04T07:49:49.541Z - **Finished:** 2026-09-04T07:52:15.826Z - **Download time:** 515 ms - **Static scan time:** 3711 ms - **AI review time:** 142058 ms - **Total time:** 146285 ms The recorded confidence comes from the underlying analysis.

Later mutating CLI use can check the registry and globally install a newer release. - **Trigger:** Global installation of llm-relay; subsequently, a mutating llm-relay CLI command when an update is available. - **Impact:** The package can alter agent behavior and route Codex requests through its local relay without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs, dist/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:52:15.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent extension setup plus global self-update. - **Rationale:** This is not a fully proven malware chain because setup is limited to global installs, uses a loopback relay, and has no runtime self-dependency. However, its automatic multi-host agent configuration and self-update mechanism warrant a warning. - **Files touched:** ~/.claude/skills/llm-relay, ~/.codex/skills/llm-relay, ~/.codex/config.toml, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package runs an installer automatically through postinstall., On global installs, the installer copies a skill bundle into Claude Code, Codex, and OpenCode configuration directories., The installer appends an llm-relay provider and MCP command to the user's Codex configuration., A runtime self-update checks the npm registry and can globally install a newer llm-relay release., The postinstall fallback asserts that the package is fine, which is self-serving text embedded in automatic install behavior. - **Evidence against:** The installer exits without changes for ordinary local installs unless explicitly forced., Codex configuration is normally gated on detecting a codex binary and points to a loopback endpoint., The manifest has no dependency on llm-relay itself, so there is no nested self-dependency lifecycle chain., The inspected code shows no credential exfiltration or remote payload execution. ## Affected versions and remediation This report applies to llm-relay@0.69.0. - Review the evidence and your use of llm-relay@0.69.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
