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 | $0.00048 | $0.03236 |
| Opus 5 | $0.00024 | $0.01618 |
| Sonnet 5 | $0.00010 | $0.00647 |
| Haiku 4.5 | $0.00005 | $0.00324 |
Grade A, and why
coauthoring-visuals 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 today.
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 — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.
coauthoring-visuals
This skill is not a drawing API reference.
drawing-visuals is the toolbox for how to draw.
coauthoring-visuals is the workflow for what to ask, in what order, how to tighten the result, and how to break it from a fresh viewer's perspective.
Open references/workflow-map.md first and decide which stage you are entering.

references/prompt-templates.md
When To Use It
- "I want to tighten this diagram together" or "let's evolve the whiteboard as we talk"
- the requirements or main claim are not stable yet, and thinking-by-drawing is the right move
- a diagram already exists, but the questions it should answer need to be restructured
- you want to verify that the result still reads for someone seeing it cold

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.

coauthoring-visuals is a skill published in the GitHub repository kamiazya/whiteboard (6 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 3,236 once invoked, about $0.0002 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 2026-08-31.
