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: 0.80). The skill's "Substitution Model Recommendation" step explicitly instructs the agent to use WebFetch to retrieve and parse the public IQ-TREE documentation at https://iqtree.github.io/doc/Substitution-Models and then use the extracted models (MODEL_SET) in generated IQ-TREE commands, meaning the agent fetches and interprets open third‑party web content that can materially change tool invocation.

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 setup script fetches and installs executable Perl scripts at runtime from raw.githubusercontent.com (e.g. https://raw.githubusercontent.com/brunoasm/my_claude_skills/main/phylo_from_buscos/scripts/predownloaded_aliscore_alicut/Aliscore.02.2.pl and the fallback https://raw.githubusercontent.com/PatrickKueck/AliCUT/master/Aliscore.02.2.pl), which are downloaded during runtime, made executable, and executed as required dependencies—so remote content directly supplies executable code for the skill.
