Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.01942 |
| Opus 5 | $0.00036 | $0.00971 |
| Sonnet 5 | $0.00015 | $0.00388 |
| Haiku 4.5 | $0.00007 | $0.00194 |
Grade A, and why
glmv-caption scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GLM-V Caption Skill
Generate captions for images, videos, and documents using the ZhiPu GLM-V multimodal model.
When to Use
- Describe, caption, summarize, or interpret image/video/document content
- User mentions "describe this image", "caption", "summarize this video", "图片描述", "视频摘要", "文档解读", "看图说话"
- Extract visual or textual information from media files
- Compare multiple images
- User provides an image/video/file and asks what's in it
Supported Input Types
| Type | Formats | Max Size | Max Count | Base64 |
|---|---|---|---|---|
| Image | jpg, png, jpeg | 5MB / 6000×6000px | 50 | ✅ |
| Video | mp4, mkv, mov | 200MB | — | ❌ |
| File | pdf, docx, txt, xlsx, pptx, jsonl | — | 50 | ❌ |
⚠️ file_url cannot mix with image_url or video_url in the same request. ⚠️ Videos and files only support URLs — local paths and base64 are NOT supported (images only).

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

glmv-caption is a skill published in the GitHub repository zai-org/GLM-skills (474 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,942 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

watching-videos
The user shared a video URL, a YouTube/TikTok/stream link, a local video file, a screen recording, a meeting recording, or a playlist/folder of videos — "watch this", "summarize this video", "what's in this recording". Use this to actually watch the video — download, extract frames, OCR, transcribe, and index it …
extracting-structure
The user wants structure pulled out of a watched video — "make chapters for this video", "where does the bug appear in this recording", "turn this screen recording into a bug report", "how strong is my intro/hook". Use this for deterministic extraction from the index — chapters with timestamps, a fileable bug report…

Vision, audio, video generation, and multimodal LLM integration patterns. Use when processing images, transcribing audio, generating speech, generating AI video (Kling v3, Sora 2, Veo 3.1 std/lite/fast, Runway Gen-4.5 via gen4turbo), or building multimodal AI pipelines.
