## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 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:** 1.13.1
- **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.

Source inspection found a postinstall patch targeting the package's pi dependency and runtime code that configures its provider credential while stripping secrets from child processes. The scanner's credential-redirection claim was not supported by the inspected source.

## 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 confirmed attack surface was identified. The install hook patches the package's pi dependency, while runtime credentials are configured for the selected service and stripped from child processes.

- **Trigger:** Installation runs the postinstall patch script; credential setup and child-process guarding occur when the CLI starts.

- **Impact:** The inspected behavior supports dependency setup and credential isolation; no credential redirection or other concrete attack was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T21:58:37.233Z

### AI review details

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

- **Mechanism:** The patch script performs targeted source replacements in the pi dependency. Runtime settings associate the API key with the u1s1 provider, and the child-process guard removes secret environment variables from spawned processes.

- **Rationale:** Source inspection found a postinstall patch targeting the package's pi dependency and runtime code that configures its provider credential while stripping secrets from child processes. The scanner's credential-redirection claim was not supported by the inspected source.

- **Files touched:** package.json, scripts/patch-pi.js, dist/index.js, dist/agent-setup.js, dist/secret-env.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook runs a patch script that targets the package's pi coding-agent dependency., The CLI places its configured API key in the process environment for its configured service flow., Generated provider settings reference that key for the u1s1 provider and use the configured base URL., The CLI installs a child-process guard that strips secret environment variables., The patch script applies text replacements to the targeted pi dependency.
