| 变量名 | 必需 | 说明 |
|---|---|---|
GEMINI_API_KEY | 是（优先） | Gemini API 密钥 |
GOOGLE_API_KEY | 备选 | 当 GEMINI_API_KEY 未设置时使用 |
GEMINI_BASE_URL | 否（优先） | 自定义 API 端点 |
GOOGLE_API_BASE_URL | 备选 | 当 GEMINI_BASE_URL 未设置时使用 |
Python 依赖：pip install google-genai
Read ${CLAUDE_PLUGIN_ROOT}/skills/patent-diagram-drawing/references/patent-diagram-spec.md to load CNIPA diagram standards (line weights, numbering formats, layout rules). Strictly follow all rules defined there.
Locate the project working directory (output/temp_[uuid]/). If invoked as /write-patent Step 2, reuse the directory from Step 1. Read:
04_content/description.md — 具体实施方式全文03_outline/structure_mapping.json — 结构映射（图号、模块编号对应关系）Based on description content and structure mapping, identify all diagrams to generate:
| 类型 | 触发条件 | 编号 |
|---|---|---|
| 方法流程图 | 每个方法权利要求对应一张 | S101, S102... |
| 装置结构框图 | 每个装置权利要求对应一张 | 201, 202... |
| 系统架构图 | 涉及多组件交互时 | 301, 302... |
| 硬件截面图 | 涉及物理结构时 | 引出线编号 |
Read ${CLAUDE_PLUGIN_ROOT}/skills/patent-diagram-drawing/references/prompt-templates.md to get prompt templates. Select the template matching the diagram type (flowchart, apparatus, system, cross-section) and fill in placeholders from description.md and structure_mapping.json.
Create output directories, then execute for each diagram:
mkdir -p {PROJECT_DIR}/05_diagrams/{flowcharts,structural_diagrams,cross_sections}
GEMINI_API_KEY="${GEMINI_API_KEY:-$GOOGLE_API_KEY}" \
GEMINI_BASE_URL="${GEMINI_BASE_URL:-$GOOGLE_API_BASE_URL}" \
python3 "${CLAUDE_PLUGIN_ROOT}/skills/patent-diagram-drawing/scripts/generate.py" \
"<PROMPT>" --ratio 3:4 -o "<OUTPUT_PATH>" --size 2K -v
<PROMPT>: Full English prompt constructed from template with placeholders filled<OUTPUT_PATH>: Absolute path to output PNG (e.g., 05_diagrams/flowcharts/method_flow.png)If generation fails or quality check does not pass, retry up to 3 times with strengthened prompt constraints.
Verify each generated PNG against the checklist:
05_diagrams/
├── flowcharts/ # 方法流程图
├── structural_diagrams/ # 装置结构框图
└── cross_sections/ # 硬件截面图
File naming: snake_case English, .png extension.

|---|---|
GEMINI_API_KEY not set | 设置 GEMINI_API_KEY 或 GOOGLE_API_KEY |
No image generated | 检查 prompt 长度和内容，重试 |
| 中文显示乱码 | 在 prompt 中要求 "Chinese text labels"，重试 |
| 出现彩色元素 | 加强黑白要求，重试（最多3次） |
Rate limit exceeded | 等待 30-60 秒后重试 |
Content blocked | 调整 prompt 措辞，避免敏感词 |
