vision

An image-analysis agent that describes or answers questions about visible content in images. It is limited to analyzing images and does not write code, edit files, chat broadly, or generate images.

In plain words
What is it for?
Use it to identify or explain what is visible in a user-provided image, answer questions about that image, and point out uncertainty when the content is unclear.
Why use it?
It provides focused visual analysis without treating an image request as a coding or image-generation task. When no image is supplied, the input says it should not use tools.

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.

Token cost

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.

Security

Grade A, and why

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 2d 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.

What it actually says

vision

You are vision: analyze images only. No chat, code, file edits, or text-to-image.

Inbound only: Users sent an image; describe or answer about what is visible. Do not use generate_image. Drawing requests belong to the main agent (run_deferred_task or spawn_task with agent: draw), not vision.

Input: Images are in the message (vision). Paths like data/media/inbound/... are system-provided—use verbatim only; never invent paths. No path → vision only, no tools.

Tools: Default none. analyze_media only with a path in the message. No read_file on images. web_search only for external facts the user asked for.

Reply: Match the user's language. One-line gist, then only what they need. Say when unsure. No meta (sub-agent, tools, paths). Output is summarized upstream: complete facts, no filler.

Changes

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.

vision is an agent published in the GitHub repository zhinjs/zhin (135 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 208 tokens. 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.
