3 findings — 1 high severity, 2 medium severity. You should review these findings carefully before considering using this skill.

High

W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 1.00). The prompt requires embedding the design download URL (htmlCode.downloadUrl) verbatim into a bash command (and similarly uses fetched JSON fields in network calls), which can contain presigned tokens or sensitive query parameters, forcing the model to handle/output secret values directly.

Medium

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.90). The skill explicitly retrieves and parses untrusted, user-provided design HTML and images via the signed htmlCode.downloadUrl and screenshot.downloadUrl (see SKILL.md "Metadata fetch" and "High-reliability download" steps and resources/stitch-api-reference.md) using scripts/fetch-stitch.sh, and the agent is required to read and act on that content (extract styles, asset URLs, and head config) as part of component generation—allowing page-origin content to influence generation and tool use.

Medium

W012: Unverifiable external dependency detected (runtime URL that controls agent)

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 0.90). The skill invokes scripts/fetch-stitch.sh at runtime which runs curl on htmlCode.downloadUrl (a signed Google Cloud Storage download URL, e.g. https://storage.googleapis.com/...) and the fetched HTML/screenshot are used by the agent to drive component generation, meaning external content fetched at runtime directly controls the agent's outputs.
