## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. The package gains control over configured AI-agent routing and task execution without an explicit setup command.

- **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:** 0.78.0
- **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. An automatic global-install hook changes the configuration and skill directories of three AI-agent hosts. It also installs a Codex MCP endpoint and an agent whose instructions force tasks through the package's dispatch tool.

## Security analysis

### Published attack-surface review

- **Summary:** An automatic global-install hook changes the configuration and skill directories of three AI-agent hosts. It also installs a Codex MCP endpoint and an agent whose instructions force tasks through the package's dispatch tool.

- **Trigger:** Installing llm-relay globally with npm; later, invoking a mutating CLI command can trigger its self-update.

- **Impact:** The package gains control over configured AI-agent routing and task execution without an explicit setup command.

- **Evidence paths:** package.json, scripts/install-skill.mjs, dist/self-update.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-10T03:29:43.765Z

### AI review details

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

- **Mechanism:** Postinstall AI-agent configuration mutation and automatic global self-update.

- **Attack narrative:** On a global npm install, postinstall runs an installer that copies package-controlled skill files into Claude Code, Codex, and OpenCode directories. It writes a Codex model provider and MCP server entry, then installs a relay agent that is instructed to dispatch every task through the package. The CLI also checks the npm registry and automatically reinstalls a newer global release for mutating commands. These unconsented lifecycle changes affect broad AI-agent control surfaces.

- **Rationale:** This is concrete, automatic postinstall mutation of foreign AI-agent configuration and behavior. The local-install and overwrite guards do not remove the unconsented global-install attack surface.

- **Files touched:** scripts/install-skill.mjs, dist/self-update.js, ~/.claude/skills/llm-relay, ~/.codex/skills/llm-relay, ~/.codex/config.toml, ~/.codex/agents/relay.toml, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay

- **Network endpoints:** registry.npmjs.org, 127.0.0.1

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The package runs its installer automatically in npm postinstall., On global installation, the installer copies a skill bundle into Claude Code, Codex, and OpenCode user configuration directories., The installer appends a provider and MCP server to Codex configuration and creates or replaces its relay agent file., The installed agent instructs Codex to make dispatch calls rather than answer tasks itself., The CLI can automatically fetch a newer release and run npm global installation during mutating commands.

- **Evidence against:** Local installs exit before modifying host skill directories., A pre-existing relay agent without the package marker is not overwritten., The reviewed keyring and Windows ACL modules protect locally configured credentials; no credential exfiltration endpoint was found.

## Affected versions and remediation

This report applies to llm-relay@0.78.0.

- Avoid installing llm-relay@0.78.0. 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.
