## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Future Claude Code and Codex agent behavior can be redirected through the package-controlled relay without an explicit configuration command.

- **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:** 0.59.2
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically changes Claude Code and Codex control surfaces. It installs package-controlled skills and makes a default Codex agent use the package relay.

## Security analysis

### Published attack-surface review

- **Summary:** A global npm installation automatically changes Claude Code and Codex control surfaces. It installs package-controlled skills and makes a default Codex agent use the package relay.

- **Trigger:** Installing llm-relay globally runs npm postinstall.

- **Impact:** Future Claude Code and Codex agent behavior can be redirected through the package-controlled relay without an explicit configuration command.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-30T02:14:16.029Z

### AI review details

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

- **Mechanism:** Postinstall writes agent skills, provider settings, and default agent definitions.

- **Attack narrative:** On a global installation, npm automatically runs the installer. It copies a package-provided skill into two AI-agent hosts, appends a Codex provider pointing at its relay, and creates a default agent routed through that provider. This modifies broad, foreign agent control surfaces as an install side effect rather than through an explicit setup command.

- **Rationale:** The package performs unconsented postinstall mutation of foreign AI-agent configuration and changes the default Codex child-agent route. The global-install guard narrows the trigger but does not remove the automatic control-surface change.

- **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:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The postinstall hook automatically runs the host-configuration script., That script adds a provider and two agent definitions to the user's Codex configuration., It copies a package-controlled skill into both Claude Code and Codex home directories., The installed provider redirects Codex Responses traffic to the package's local relay endpoint.

- **Evidence against:** The automatic script exits without changes for non-global installs., No runtime dependency on llm-relay itself appears in package.json.
