## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.19.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

No concrete malicious install-time behavior or unconsented foreign control-surface mutation was found. The package nevertheless has a real first-party AI-agent extension lifecycle surface that warrants a warning.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Explicit \`omx setup\` configures package-owned Codex extension surfaces; launch/resume can maintain its local plugin registration. The install hook itself only records a version stamp.

- **Trigger:** User runs \`omx setup\`, \`omx\`, or \`omx resume\`; not npm postinstall for configuration changes.

- **Impact:** Can alter Codex configuration and project/user agent guidance when the CLI is invoked.

- **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/cli/setup.js, dist/cli/index.js, dist/autoresearch/runtime.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-26T12:22:14.036Z

### AI review details

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

- **Mechanism:** first-party Codex plugin/config and hook setup

- **Rationale:** No concrete malicious install-time behavior or unconsented foreign control-surface mutation was found. The package nevertheless has a real first-party AI-agent extension lifecycle surface that warrants a warning.

- **Files touched:** ~/.omx/install.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.codex/agents/, \<project\>/.codex/, \<project\>/AGENTS.md, \<project\>/.omx/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** \`dist/cli/setup.js\` explicitly writes Codex config, hooks, agents, skills, prompts, and AGENTS.md., \`dist/cli/index.js\` can register and enable the packaged OMX Codex plugin during CLI launch/resume., \`dist/autoresearch/runtime.js\` executes a user-provided evaluator command with \`shell: true\`.

- **Evidence against:** \`package.json\` postinstall only imports \`dist/scripts/postinstall.js\`., \`dist/scripts/postinstall.js\` runs only for global installs, writes an install-version stamp, and states setup is opt-in., No credential harvesting, covert exfiltration, or install-time network/payload execution was found., Runtime network features are explicit update, URL-reader, native-download, or configured notification functionality.

## Affected versions and remediation
