What it does

Glmv Caption is an agent skill from zai-org/GLM-skills. Generate captions (descriptions) for images, videos, and documents using ZhiPu GLM-V multimodal model series. Use this skill whenever the user wants to describe, caption, summarize, or interpret the content of images, videos, or files. Supports single/multiple inputs, URLs, local paths, and base64 (images only).

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/glmv_caption.py`).

It sits in Documents & Office. It works with Zhipu GLM. The repository describes itself as: Official skills for the GLM family of models. The licence is Apache-2.0.

When your agent uses it

The user wants to describe
Interpret the content of images

Example prompts

“/glmv-caption”

Requirements

Python 3
A credential in ZHIPU_API_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

OpenClaw config (recommended) / OpenClaw 配置（推荐）： Set in openclaw.json under skills.entries.glmv-caption.env
Shell environment variable / Shell 环境变量： Add to ~/.zshrc
.env file / .env 文件： Create .env in this skill directory

What it can do on your machine

Read from SKILL.md and the folder at commit 2ecd31c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- bigmodel.cn
Also links to:
- docs.bigmodel.cn
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- ZHIPU_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Glmv Caption loads about 2k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 566 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~82
When it runs · the whole SKILL.md, loaded when a task matches: ~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Prerequisites

API Key Setup / API Key 配置（Required / 必需）

This script reads the key from the ZHIPU_API_KEY environment variable and shares it with other Zhipu skills. 脚本通过 ZHIPU_API_KEY 环境变量获取密钥，与其他智谱技能共用同一个 key。

Get Key / 获取 Key： Visit Zhipu Open Platform API Keys / 智谱开放平台 API Keys to create or copy your key.

Setup options / 配置方式（任选一种）：

OpenClaw config (recommended) / OpenClaw 配置（推荐）： Set in openclaw.json under skills.entries.glmv-caption.env:
json
```
"glmv-caption": { "enabled": true, "env": { "ZHIPU_API_KEY": "你的密钥" } }
```
Shell environment variable / Shell 环境变量： Add to ~/.zshrc:
bash
```
export ZHIPU_API_KEY="你的密钥"
```
.env file / .env 文件： Create .env in this skill directory:
```
ZHIPU_API_KEY=你的密钥
```

⛔ MANDATORY RESTRICTIONS - DO NOT VIOLATE ⛔

ONLY use GLM-V API — Execute the script python scripts/glmv_caption.py
NEVER caption media yourself — Do NOT try to describe content using built-in vision or any other method
NEVER offer alternatives — Do NOT suggest "I can try to describe it" or similar
IF API fails — Display the error message and STOP immediately
NO fallback methods — Do NOT attempt captioning any other way

📋 Output Display Rules (MANDATORY)

After running the script, you must show the full raw output to the user exactly as returned. Do not summarize, truncate, or only say "generated". Users need the original model output to evaluate quality.

Image captioning: show the full caption text
Multiple images: show each image result
Video/files: show the full understanding result
If token usage is included, you may optionally display it
