Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from Markdown fences, TypeScript template literals, relative imports, and normal frontend configuration examples. Two command blocks execute remote npm tooling, and the authentication templates persist bearer tokens in browser storage. Review package sources and replace persistent token storage before publication.

Capability review items (3)
Medium
SKILL.md:485-497
Ruby/shell backtick execution
```bash
The fenced block runs npm and npx scaffolding commands, including latest package versions. These commands download and execute remote package code.
Medium
SKILL.md:500-525
Ruby/shell backtick execution
```bash
The fenced block instructs npm and npx dependency installation and initialization. Package lifecycle scripts can execute code from remote dependencies.
Medium
SKILL.md:354-359SKILL.md:392-410
Persistent Bearer Token Exposure
The templates read a bearer token from localStorage and persist the authentication token in Zustand state. An XSS flaw or browser extension could steal it.
The examples explicitly retrieve and persist the authentication token in browser storage, creating a clear credential-exposure pattern.

Risk findings

Confirmed security concerns are separated from items that still need review.

No confirmed security findings were recorded for this completed audit.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Scaffolding and dependency examples run remote npm packages, including unpinned latest versions.
    Pin reviewed package versions, verify package names and lockfiles, and require user confirmation before running npm or npx commands.
  2. FIX-002
    Medium
    Authentication examples store bearer tokens in localStorage and persisted Zustand state.
    Prefer short-lived memory storage or secure HttpOnly cookies, and prevent authentication state from entering production developer tools.
