writing-guidelines
Review or write docs/prose for Writing Guidelines compliance. Use when asked to "review my docs", "check writing style", "audit prose", "review docs voice and tone", "check this page against the writing handbook" — and proactively whenever writing or editing content under docs/src/content/docs/, since that's this repo's default docs style.

2 low severity findings. Worth noting, but not necessarily harmful.
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
The required workflow fetches public web content at runtime from `https://raw.githubusercontent.com/vercel-labs/writing-guidelines/main/command.md` via WebFetch and ingests that fetched free-form text into the agent’s LLM context to perform rule checks.
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
The skill explicitly instructs the agent to "Fetch fresh guidelines before each review" via WebFetch at runtime from https://raw.githubusercontent.com/vercel-labs/writing-guidelines/main/command.md, and the fetched document "contains all the rules and output format instructions" which will directly control the agent's prompt/rules during execution.
