## 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:** 0.4.0
- **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.

LPM treats this as warn-only first-party agent extension lifecycle risk. A global installation automatically configures a detected Claude Code installation. It writes a status-line hook, a slash command, and a permission allowing its local post command.

## Security analysis

### Published attack-surface review

- **Summary:** A global installation automatically configures a detected Claude Code installation. It writes a status-line hook, a slash command, and a permission allowing its local post command.

- **Trigger:** Installing the package globally with npm on a machine where Claude Code is detected.

- **Impact:** It changes an AI-agent control surface without an explicit install command and can persist through future package updates.

- **Evidence paths:** package.json, dist/postinstall.js, dist/commands/install.js, dist/adapters/claude.js, dist/update.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-06T03:12:53.335Z

### AI review details

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

- **Mechanism:** Automatic postinstall integration that mutates Claude Code configuration and later self-updates globally.

- **Rationale:** This is not proven malware, but a postinstall hook automatically modifies a third-party AI-agent configuration and grants a command permission. The scoped behavior and absence of harvesting reduce the severity, while detached self-update keeps the risk unresolved.

- **Files touched:** ~/.claude/settings.json, ~/.claude/commands/pinglet.md, ~/.pinglet/config.json, ~/.pinglet/update.json

- **Network endpoints:** https://pinglet.halluci.co.kr, https://registry.npmjs.org/pinglet-cli/latest

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The postinstall hook automatically runs setup on global installation., Setup detects Claude Code and installs an integration by default., The integration rewrites Claude settings, adds a command permission, and writes a slash-command file., Routine refresh checks the npm registry and silently starts a global self-update.

- **Evidence against:** The installer is limited to global installs and exits for ordinary dependency installs., Existing status-line configuration is not replaced unless forced or confirmed., Network requests are limited to the package service and npm registry; no credential or file harvesting was found., Codex integration requires an explicit --codex option.

## Affected versions and remediation

This report applies to pinglet-cli@0.4.0.

- Review the evidence and your use of pinglet-cli@0.4.0 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.
