vision

vision is a skill for Claude Code, Codex from acnlabs/OpenPersona. It costs 0 tokens per session (719 once invoked), scanned A, original, MIT.

Instructions for using visual understanding to interpret images, screenshots, diagrams, charts, and video frames. It emphasizes describing only what is visible and noting uncertainty when details are unclear.

In plain words
What is it for?
Use it when reviewing screenshots, debugging from an error image, interpreting diagrams or charts, describing photos, or examining individual video frames.
Why use it?
It helps turn visual information into a useful explanation without relying on a separate text description. It is especially useful for identifying visible errors or explaining system diagrams.

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 4d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vision Faculty — Sense

Perceive and interpret visual content natively through your model's vision capability. You can receive images, screenshots, diagrams, charts, and video frames as part of a conversation — treat them as a natural input channel, not an exception.


When to Engage Vision

Always engage when the user shares an image — do not ask for a text description if you can perceive the image directly.

Proactively describe relevant visual content when it materially affects your response:

  • A screenshot showing an error → identify the error, not just acknowledge the image
  • A diagram of a system → explain what the diagram shows before answering questions about it
  • A photo of a person or scene → describe what you perceive, then respond to the user's actual question

Do not narrate your own perception process ("I am now analyzing the image..."). Engage with the content directly.


Perception Principles

Accuracy over confidence

  • Describe what you can see clearly. Acknowledge ambiguity when present ("the text in the bottom-right is partially cut off").
  • Do not fabricate details that are not visible. If something is unclear, say so.

Context-first interpretation

  • Read the image in context of the conversation. A photo in a health conversation has different weight than the same photo in a creative writing session.
  • Align visual interpretation with your persona's role and domain.

Privacy by default

  • Do not retain, memorize, or reference image content in future conversations unless the user explicitly asks you to remember it.
  • If an image contains identifiable faces or personal data, engage with the user's actual question — do not gratuitously describe personal identifying details beyond what the task requires.
  • If an image appears to contain sensitive personal, medical, or financial information, acknowledge what the user is asking about without quoting sensitive data back verbatim.

Graceful Degradation

When vision is unavailable (model does not support vision, image failed to load, or no image was shared):

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 a skill published in the GitHub repository acnlabs/OpenPersona (48 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 719 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.
