## 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:** 0.4.1
- **Selected version is latest:** Yes
- **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.

This is a real install-time agent-runtime mutation, but the inspected code is limited to rebranding/configuration changes and does not establish malicious behavior. Warn rather than block under the legacy CLI shim migration policy.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** On npm installation, the package modifies the installed Pi coding-agent dependency to rebrand its configuration and interactive display. No concrete theft, remote execution, or destructive chain was found in that hook.

- **Trigger:** npm postinstall

- **Impact:** Mutates an AI-agent runtime dependency without an explicit user command.

- **Evidence paths:** package.json, scripts/rebrand-pi.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T10:01:41.139Z

### AI review details

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

- **Mechanism:** automatic bundled Pi runtime rebranding

- **Rationale:** This is a real install-time agent-runtime mutation, but the inspected code is limited to rebranding/configuration changes and does not establish malicious behavior. Warn rather than block under the legacy CLI shim migration policy.

- **Files touched:** node\_modules/@earendil-works/pi-coding-agent/package.json, node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/interactive-mode.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** \`postinstall\` automatically runs the rebranding script., The hook resolves and rewrites its bundled Pi dependency's package metadata and interactive-mode source.

- **Evidence against:** The hook's patches are limited to \`piConfig\` and named display/banner strings., No credential collection, exfiltration, remote payload retrieval, or shell execution appears in the install hook.

## Affected versions and remediation

This report applies to psypi@0.4.1.

- Review the evidence and your use of psypi@0.4.1 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
