SkillsBench is a benchmark for measuring how effectively AI agents use modular skills—folders containing instructions, scripts, and resources—to complete specialized tasks. It helps researchers and developers evaluate both skill quality and agent behavior, including tasks that require combining multiple skills. The catalogue’s skills and instructions are evaluated as part of this workflow.
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.

What it costs to keep this loaded
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 | $0.00017 | $0.04461 |
| Opus 5.5 | $0.00007 | $0.01784 |
| Sonnet 5.5 | $0.00003 | $0.00892 |
| Haiku 4.5 | $0.00002 | $0.00446 |
Grade A, and why
openai-vision 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 1mo 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.

OpenAI Vision Analysis Skill
Purpose
This skill enables image analysis, scene understanding, text extraction, and multi-frame comparison using OpenAI's vision-capable GPT models (e.g., gpt-4o, gpt-4o-mini). It supports single images, multiple images for comparison, and sequential frames for temporal analysis.
When to Use
- Analyzing image content (objects, scenes, colors, spatial relationships)
- Extracting and reading text from images (OCR via vision models)
- Comparing multiple images to detect differences or changes
- Processing video frames to understand temporal progression
- Generating detailed image descriptions or captions
- Answering questions about visual content
Required Libraries
The following Python libraries are required:
from openai import OpenAI
import base64
import json
import os
from pathlib import Path
Input Requirements
- File formats: JPG, JPEG, PNG, WEBP, non-animated GIF
- Image sources: URL, Base64-encoded data, or local file paths
- Size limits: Up to 20MB per image; total request payload under 50MB
- Maximum images: Up to 500 images per request
- Image quality: Clear, legible content; avoid watermarks or heavy distortions
Output Schema
Analysis results should be returned as valid JSON conforming to this schema:
{
"success": true,
"images_analyzed": 1,
"analysis": {
"description": "A detailed scene description...",
"objects": [
{"name": "car", "color": "red", "position": "foreground center"},
{"name": "tree", "count": 3, "position": "background"}
],
"text_content": "Any text visible in the image...",
"colors": ["blue", "green", "white"],
"scene_type": "outdoor/urban"
},
"comparison": {
"differences": ["Object X appeared", "Color changed from A to B"],
"similarities": ["Background unchanged", "Layout consistent"]
},
"metadata": {
"model_used": "gpt-4o",
"detail_level": "high",
"token_usage": {"prompt": 1500, "completion": 200}
},
"warnings": []
}
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.

openai-vision is a skill published in the GitHub repository benchflow-ai/skillsbench (1,871 stars, last pushed 2d ago), licensed Apache-2.0. It adds 17 tokens to every session and 4,461 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
