CRITICAL RULE: Never read a full PDF. Never. Only read the 4-page split files, and only 3 splits at a time (~12 pages). Reading a full PDF will either crash the session with an unrecoverable "prompt too long" error, destroying all context, or produce shallow, hallucinated output. There are no exceptions.

When to invoke it: Use when asked to read, review, or summarize an academic paper. Splits PDFs into 4-page chunks, reads them in small batches, and produces structured reading notes, avoiding context window crashes and shallow comprehension.
