What problem does it solve? Technical design documents often arrive as PDFs that AI coding agents cannot easily read or act on, and embedded flowcharts lose their logic when copied as plain text. This Skill converts a PDF design document into a structured Markdown file saved under .Knowledge/req-docs/, and optionally captures flowchart logic as written steps so the design can later drive code implementation. ## Core Features & Use Cases - PDF to Markdown Conversion: Reads a user-supplied PDF path, extracts text while preserving tables, sections, lists, and code blocks, and saves the result as .Knowledge/req-docs/<name>.md. - Flowchart Supplementation: Prompts the user to provide flowchart images or written step descriptions, then appends a structured "流程说明" (process description) section to the generated Markdown. - Optional Sub-Agent Splitting: For large PDFs (over 50 pages or roughly 5MB of text), a sub-agent can produce the first Markdown draft while the main agent handles user follow-up questions. - Use Case: You receive a 30-page technical design PDF for a new feature. Run this Skill to convert it into Markdown, paste the flowchart screenshots into the chat, and get a complete implementation-ready document that the implement-tech-design rule can consume. ## Quick Start Convert the PDF at ~/Downloads/tech-design.pdf into Markdown and save it to .Knowledge/req-docs/, then help me add the flowchart steps.
