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.
SKILL.md describes an A2A client workflow where the caller sends free-form `text` to a remote agent via `callAgent()` / `client.send()` and the receiver then uses that message as LLM input for the remote agent run, so outsider-authored user/peer text can be fed into the agent context (and is explicitly treated as untrusted presentation when included in streamed/agent-activity updates).
