Highest confirmed finding severity

1 confirmed security finding requires attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

No prompt injection or secret exfiltration intent was found in the reviewed files. Most external-command findings are false positives from JavaScript template literals, Markdown fences, or inline code. The skill has intentional outbound network access for Expo references and should keep that access constrained.

Report position

Latest published report

Latest refers to the report sequence, not to artifact currentness.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (1)
Low
scripts/fetch.js:22
Fetch API call
const response = await fetch(url, {
The helper performs outbound HTTP requests to a caller-supplied URL and caches the response. This is intended for documentation fetches, with no secret exfiltration evidence, but it is real network capability.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
scripts/fetch.js:95-107
Unrestricted Documentation Fetch URL
scripts/fetch.js reads a command-line URL and fetches it without host allowlisting. The intended use is Expo documentation, but prompts could cause outbound requests to arbitrary domains.
The CLI path assigns process.argv[2] to url and passes it to fetchCached. No code in this file restricts the destination host.

Remediation

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

  1. FIX-001
    Low
    The fetch helper accepts any command-line URL.
    Restrict accepted hosts to api.expo.dev and raw.githubusercontent.com, or require explicit approval for other hosts.
  2. FIX-002
    Low
    The skill depends on live network references during generation and validation.
    Clearly disclose network fetches and cache only public documentation or schema responses.
