A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

list_documents.get_ingest_status.search_pdf_context (use document, chapter_id, page_* when known).(document, page) before synthesizing; retry with paraphrase if no good match.get_section_content + get_next_chunks over search alone.end_page often equals start_page; infer span from next chapter or use get_next_chunks.source metadata in answers.If several pdf-context servers exist (e.g. pdf-textbooks, pdf-papers), use the server whose corpus matches the user's document. Do not search all servers unless asked.
When claims come from PDF tools, cite filename + page from chunk metadata. Do not invent page numbers.
