Prerequisites / 前置条件
API Key Setup / API Key 配置(Required / 必需)
脚本通过 ZHIPU_API_KEY 环境变量获取密钥,可与其他智谱技能复用同一个 key。
This script reads the key from the ZHIPU_API_KEY environment variable. Reusing the same key across Zhipu skills is optional.
Get Key / 获取 Key: Visit 智谱开放平台 API Keys to create or copy your key.
Setup options / 配置方式(任选一种):
-
Global config (recommended) / 全局配置(推荐): Set once in
openclaw.jsonunderenv.vars, all Zhipu skills will share it:{ "env": { "vars": { "ZHIPU_API_KEY": "你的密钥" } } } -
Skill-level config / Skill 级别配置: Set for this skill only in
openclaw.json:{ "skills": { "entries": { "glmocr-table": { "env": { "ZHIPU_API_KEY": "你的密钥" } } } } } -
Shell environment variable / Shell 环境变量: Add to
~/.zshrc:export ZHIPU_API_KEY="你的密钥"
💡 如果你已为其他智谱 skill(如
glmocr、glmv-caption、glm-image-generation)配置过 key,它们共享同一个ZHIPU_API_KEY,无需重复配置。
Security & Transparency / 安全与透明度
- Environment variables used / 使用的环境变量:
ZHIPU_API_KEY(required / 必需)GLM_OCR_TIMEOUT(optional timeout seconds / 可选超时秒数)
- Fixed endpoint / 固定官方端点:
https://open.bigmodel.cn/api/paas/v4/layout_parsing - No custom API URL override / 不支持自定义 API URL 覆盖: this avoids accidental key exfiltration via redirected endpoints.
- Raw upstream response is optional / 原始响应默认不返回: use
--include-rawonly when needed for debugging.
⛔ MANDATORY RESTRICTIONS / 强制限制 ⛔
- ONLY use GLM-OCR API — Execute the script
python scripts/glm_ocr_cli.py - NEVER parse tables yourself — Do NOT try to extract tables using built-in vision or any other method
- NEVER offer alternatives — Do NOT suggest "I can try to recognize it" or similar
- IF API fails — Display the error message and STOP immediately
- NO fallback methods — Do NOT attempt table extraction any other way
📋 Output Display Rules / 输出展示规则
After running the script, present the OCR result clearly and safely.
- Show extracted table Markdown (
text) in full - Summarization is allowed, but do not hide important extraction failures
- If
layout_detailscontains table-related entries, you may highlight them - If the result file is saved, tell the user the file path
- Show raw upstream response only when explicitly requested or debugging (
--include-raw)
How to Use / 使用方法
Extract from URL / 从 URL 提取
python scripts/glm_ocr_cli.py --file-url "https://example.com/table.png"
Extract from Local File / 从本地文件提取
python scripts/glm_ocr_cli.py --file /path/to/table.png
Save Result to File / 保存结果到文件

FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed.
