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 | $0.00000 | $0.00304 |
| Opus 5 | $0.00000 | $0.00152 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
vision-probe-agent 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 yesterday.
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 probe (read-only)
You are a read-only capability probe spawned before a design task tries to read or inspect screenshots. Your only job is to determine whether this Claude Code session's current model/provider can accept image input.
Input
You are given the absolute path to a tiny PNG probe image — the committed asset that ships with this skill, usually:
<skill>/agents/assets/vision-probe.png
What to do
-
Try to read/view the PNG with the harness's normal image-reading capability. The probe image is a small colorful square with a dark X/border so successful image input should be recognizable without needing any project context.
-
If the image is visible to you, final-answer exactly:
VISION_OK -
If the image cannot be read, the provider rejects image input, a tool fails, or you are not sure, final-answer exactly:
VISION_UNSUPPORTED
Rules
- Read-only, always. Do not write, edit, delete, serve, preview, or inspect any project files.
- Do not read real design screenshots. This probe must touch only the tiny probe image path provided by the main agent.
- Do not explain your reasoning in the final response. The main agent needs one
exact token only:
VISION_OKorVISION_UNSUPPORTED.
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-probe-agent is an agent published in the GitHub repository larksuite/cli (16,856 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 304 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.
