## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 15 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:** 1.47.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Inspected source shows a repair-only postinstall and visible setup nudges; the agent integration changes occur in CLI setup paths. The flagged embedding and prediction modules implement ordinary provider requests and database-backed prediction storage, with no source-grounded attack identified.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean

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 malicious attack was identified. Package installation repairs an existing opted-in Codex wrapper and prints setup guidance; agent setup is performed by CLI integration logic.

- **Trigger:** npm installation triggers the postinstall wrapper; agent integration setup runs through the CLI.

- **Impact:** No install-triggered foreign agent configuration mutation or confirmed credential exfiltration was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T05:43:21.650Z

### AI review details

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

- **Mechanism:** The postinstall invokes repair logic for an existing Codex wrapper and prints notices. CLI setup checks project markers before installing agent hooks or plugins.

- **Rationale:** Inspected source shows a repair-only postinstall and visible setup nudges; the agent integration changes occur in CLI setup paths. The flagged embedding and prediction modules implement ordinary provider requests and database-backed prediction storage, with no source-grounded attack identified.

- **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The install hook delegates to a wrapper that imports the postinstall module; that module only repairs an existing Codex wrapper and prints setup nudges., The detected agent integrations are processed by the CLI auto-setup function; the install hook does not call that function., The OpenCode plugin installer is exposed as a function for setup, while the CLI detects project agent markers before running integration setup., Embedding providers send requests to the configured provider URL; this is ordinary provider operation, not evidence of credential theft., Prediction storage validates inputs and writes package data through the database API., The capture target reads Claude project entries and returns without doing so when the directory is absent., The referenced hooks declaration describes plugin install and uninstall operations.
