## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Subsequent Claude Code and Codex sessions may load package-supplied instructions and route child agents through the relay.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.38.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Global npm installation silently changes Claude Code and Codex configuration. It adds a relay provider and agent definitions that alter AI-agent routing.

## Security analysis

### Published attack-surface review

- **Summary:** Global npm installation silently changes Claude Code and Codex configuration. It adds a relay provider and agent definitions that alter AI-agent routing.

- **Trigger:** npm install -g llm-relay

- **Impact:** Subsequent Claude Code and Codex sessions may load package-supplied instructions and route child agents through the relay.

- **Evidence paths:** package.json, scripts/install-skill.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T07:49:17.365Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall mutation of foreign AI-agent skills and configuration

- **Attack narrative:** Installing this package globally invokes a postinstall script that writes into Claude Code and Codex home configuration directories without a separate user command. It installs package-controlled skill instructions, adds a loopback model provider, and creates default child-agent configurations. This is a foreign AI-agent control-surface mutation at install time.

- **Rationale:** The global-install guard limits scope but does not make these postinstall changes user-consented. The package automatically modifies external AI-agent configuration and routing surfaces.

- **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

- **Network endpoints:** http://127.0.0.1:8791/v1

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs install-skill.mjs during postinstall., On global install, installer copies a skill into both ~/.claude and ~/.codex., Installer appends a Codex provider and creates global Codex agent files.

- **Evidence against:** Local installs exit without modifying host directories., Configured provider is loopback-only; no credential exfiltration was found in inspected files.
