## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Changes provider, MCP, skill, and subagent behavior without an interactive setup action.

- **Verdict:** AI-agent control-surface policy finding
- **Product-default install policy:** Warn by default; block when configured
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.77.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

LPM flags this version as an AI-agent control-surface risk. A global npm install automatically changes configuration for three AI-agent products. It installs a relay agent that forces tasks through this package's dispatch tool.

## Security analysis

### Published attack-surface review

- **Summary:** A global npm install automatically changes configuration for three AI-agent products. It installs a relay agent that forces tasks through this package's dispatch tool.

- **Trigger:** Installing llm-relay globally through npm activates postinstall.

- **Impact:** Changes provider, MCP, skill, and subagent behavior without an interactive setup action.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T20:43:49.636Z

### AI review details

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

- **Mechanism:** Lifecycle-driven cross-product AI-agent configuration and task-routing injection.

- **Attack narrative:** The package's npm postinstall runs automatically for global installs. It copies its skill bundle into Claude Code, Codex, and OpenCode directories, then modifies Codex configuration to register the package as a provider and MCP server and writes a relay subagent. That subagent is explicitly prohibited from answering tasks itself and must dispatch each task through llm-relay. This is an unconsented lifecycle mutation of multiple foreign AI-agent control surfaces.

- **Rationale:** This is concrete install-time AI-agent control-surface mutation, not merely a user-invoked setup command. The global-install guard does not make the automatic cross-product configuration changes consensual.

- **Files touched:** ~/.claude/skills/llm-relay, ~/.codex/skills/llm-relay, ~/.config/opencode/skills/llm-relay, ~/.codex/config.toml, ~/.codex/agents/relay.toml

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The postinstall hook automatically runs the host-setup installer., On global installation, the installer copies skills into Claude Code, Codex, and OpenCode configuration directories., The lifecycle installer creates or modifies Codex provider and MCP configuration and installs a relay subagent., The installed subagent is instructed to send every task through the package dispatch tool rather than answer itself.

- **Evidence against:** The installer exits for ordinary local installs unless explicitly forced., It avoids overwriting a pre-existing Codex relay agent that lacks its ownership marker.

## Affected versions and remediation

This report applies to llm-relay@0.77.1.

- Avoid installing llm-relay@0.77.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
