## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 8.7.5
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

No concrete attack was identified in the inspected JavaScript. The package downloads and bootstraps its own release, then delegates explicit CLI commands to it.

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:** No concrete attack was identified in the inspected JavaScript. The package downloads and bootstraps its own release, then delegates explicit CLI commands to it.

- **Trigger:** npm postinstall installs the runtime; invoking a packaged CLI also checks installation.

- **Impact:** The visible behavior installs and launches the package runtime; no credential harvesting, exfiltration, or broad agent-control mutation was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-30T02:51:36.285Z

### AI review details

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

- **Mechanism:** The installer downloads a versioned archive and checks its checksum, extracts it into the package, and runs its runtime bootstrap with optional integrations disabled.

- **Rationale:** The inspected entrypoints implement a transparent, package-aligned release installer and CLI launcher without concrete malicious behavior. The external release remains outside the static inspection scope, but that limitation alone does not establish an attack.

- **Network endpoints:** https://github.com/SeemSeam/claude\_codex\_bridge/releases/download/v${version}

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook invokes the inspected package installer; no runtime self-dependency is declared., Runtime bootstrap uses package-local installation paths and disables role and Neovim installation., The CLI runner forwards user arguments to the installed package executable., Release downloads default to the matching version in the package's GitHub repository., The installer checks the downloaded archive against its release checksum before extraction.

- **Evidence against:** Downloaded release code is outside this snapshot, and its checksum comes from the same configurable release source.
