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's workflow (notably the context_explore, context_get, and board_list_items tools) explicitly reads content from Miro board URLs — user-generated third-party content (documents, frames, prototypes, tables, images) — which the agent ingests and can influence its subsequent actions.
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: 0.80). The skill accepts Miro board URLs at runtime (e.g., https://miro.com/app/board/uXjVK123abc=/?moveToWidget=3458764612345) and uses tools like context_get/context_explore to fetch board content that is injected into the agent context and can directly control prompts, so this is a runtime external dependency controlling agent instructions.
