Process user-provided patent figures and generate formal drawing descriptions. Use when user says "附图处理", "figure description", "附图说明", "drawings description", or wants to describe patent figures with reference numerals.

Figure Description for Patents Process patent figures and generate drawing descriptions based on: $ARGUMENTS Unlike /paper figure which generates data plots, this skill processes user provided technical diagrams and assigns reference numerals. Constants FIGURE DIR = "patent/figures/" — Output directory for figure descriptions REFERENCE NUMERAL PREFIX = 100 — Starting numeral for first figure's components NUMERAL SERIES = 100 — Each figure uses a separate 100 series (Fig 1: 100 199, Fig 2: 200 299, etc.) Inputs 1. User provided figures (PNG, JPG, SVG, PDF) — search for them in the project directory 2. patent/INVENTION DISCLOSURE.md — for understanding what components to identify 3. patent/CLAIMS.md — for mapping numerals to claim elements Workflow Step 1: Discover Figures 1. Search the project directory for figure files: Check patent/figures/ , figures/ , root directory Look for PNG, JPG, SVG, PDF files Check INVENTION BRIEF.md or INVENTION DISCLOSURE.md for figure references 2. List all discovered figures with their paths 3. If figures are missing that claims require, note them as [MISSING: description needed] Step 2: Analyze Each Figure For each figure found: 1. Read the image using the Read tool (supports image files) 2. Identify components : What labeled or visually distinct components are shown? 3. Identify connections : How do components relate to each other? 4. Identify flow : If it's a flowchart or sequence, what is the step order? Step 3: Assign Reference Numerals For each figure, assign numerals using the series convention: Figure Numeral Range FIG. 1 100 199 FIG. 2 200 299 FIG. 3 300 399 For each identified component: Assign the next available numeral in the series Cross reference to the claim elements it supports Note if a component appears in multiple figures (use same numeral across figures) Step 4: Generate Drawing Descriptions Write formal drawing descriptions (附图说明): For CN jurisdiction (Chinese) : For US/EP jurisdiction (English) : Step 5: Generate Reference Numeral Index Create a complete mapping: Step 6: Cross Reference to Claims Verify that every claim element has at least one reference numeral: Claim Element Figure Numeral Status [element] [which fig] [numeral] Covered / [MISSING] If any claim element has no corresponding figure or numeral, flag it: [MISSING FIGURE: Need a diagram showing {element description}] [MISSING NUMERAL: Component {name} in figure {X} needs a numeral] Step 7: Output Write patent/figures/figure descriptions.md : Write patent/figures/numeral index.md : Key Rules Every component in every figure must have a reference numeral. Every reference numeral must be explained in the specification. Numeral series must be consistent: 100 series for FIG. 1, 200 series for FIG. 2. If the same component appears in multiple figures, use the SAME numeral. Do NOT modify user provided figures only describe them. Flag missing figures that the claims require but the user has not provided. Drawing descriptions are one sentence each, in a consistent format.
