[INDIRECT_PROMPT_INJECTION]: The skill processes external information by fetching documentation from nextjs.org using the WebFetch tool.
Ingestion points: Official Next.js upgrade guides and codemod documentation in markdown/HTML format.
Boundary markers: No explicit delimiters are specified to isolate fetched instructions from the agent's core instructions.
