x-guide
Use when the user wants a complex input (file, function, directory, PRD, plan, spec, URL, pasted prose, or vague feature name) explained step by step in a comprehension-gated walkthrough — produces a persistent .x-guide/<slug>/GUIDE.md with full TOC and walks the user one part at a time, supports resume across sessions

Low-risk findings.
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
Yes: Step 2 routes `url`/`vague` inputs to `x-research`/`x-gemini` and Step 2 explicitly reads `WebFetch` for URLs (and synthesizes web sources in x-research), so outsider-authored free text from fetched pages can be ingested and then used to generate Phase 3/4 content in the agent’s LLM context.
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 treats user-supplied http/https URLs as runtime inputs and will WebFetch and ingest their content (e.g., `https://stripe.com/docs/api` and `https://stripe.com/docs/api/payment_intents`) to drive TOC/part generation, so fetched remote content directly controls prompts used during generation.
