## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Future Codex child-agent traffic can be routed through the package's local relay, and package-controlled skills are installed into two agent hosts.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default

- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.59.1
- **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 modifies Codex and Claude Code host configuration. It adds a relay provider and a default-named Codex agent without a separate setup command.

## Security analysis

### Published attack-surface review

- **Summary:** A global npm installation automatically modifies Codex and Claude Code host configuration. It adds a relay provider and a default-named Codex agent without a separate setup command.

- **Trigger:** Installing the package globally through npm activates postinstall.

- **Impact:** Future Codex child-agent traffic can be routed through the package's local relay, and package-controlled skills are installed into two agent hosts.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-30T01:56:53.804Z

### AI review details

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

- **Mechanism:** Automatic lifecycle writes to AI-agent configuration and skill directories.

- **Attack narrative:** A global installation executes postinstall and writes a new model provider into the user's Codex configuration. It then creates a default-named Codex agent that selects that provider and copies package-controlled skills into Codex and Claude Code. This is an unconsented lifecycle mutation of broad, foreign AI-agent control surfaces. The package also contains a registry-driven global self-updater, increasing the persistence of later package changes.

- **Rationale:** The global-only guard limits scope, but it does not make the automatic writes to ~/.codex/config.toml and a default agent user-invoked. This is a concrete postinstall AI-agent control-surface mutation and warrants blocking. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape.

- **Files touched:** ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.codex/agents/relay\_coding.toml, ~/.codex/skills/llm-relay/SKILL.md, ~/.claude/skills/llm-relay/SKILL.md

- **Network endpoints:** http://127.0.0.1:8791/v1, registry.npmjs.org

### Review decision

- **Verdict:** Malicious

- **Confidence:** 93.0%

- **Recommended action:** publish\_block

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** The npm postinstall hook automatically runs the host-configuration script., On global installation, that script writes a Codex provider into the user configuration and creates a broadly named default agent., The same automatic path copies package-controlled skills into both Claude Code and Codex directories., The runtime updater queries the npm registry and can replace the global installation with a newer release.

- **Evidence against:** The postinstall script exits without changes for ordinary local installs., It does not overwrite existing agent files with the same names., The inspected configuration targets a loopback relay and no secret-exfiltration path was confirmed.
