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 | $0.00046 | $0.00646 |
| Opus 5 | $0.00023 | $0.00323 |
| Sonnet 5 | $0.00009 | $0.00129 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
hand-drawn-infographic-creator 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 13d 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hand-Drawn Infographic Creator
Purpose
Turn a semantic board prompt into a final image-generation prompt for a sparse hand-drawn whiteboard infographic. This skill produces prompt text and review notes only. It does not create video, audio, animation coordinates, or final board-control JSON.
Output
For each board, write a creator output file and a final image prompt:
creator_outputs/board-XX.creator_output.md
imagegen_prompts/board-XX.imagegen_prompt.txt
The final prompt is the input for an image model. If the image tool returns only a preview, the operator must manually save the PNG into:
images/board-XX.model-generated.png
Visual Style
- Hand-drawn whiteboard explanation.
- Engineer's notebook sketch.
- Continuous charcoal line art.
- Parchment/whiteboard background.
- Sparse labels, not a full transcript.
- Margin annotations only where they clarify the diagram.
Palette:
background: "#faf8f3"
primary_line: "#1a2332"
annotation: "#2d5a7b"
positive: "#4a9d9e"
risk: "#e63946"
insight: "#f4a261"
Use one or two semantic highlight colors per board. Use color for meaning, not decoration.
Prompt Requirements
Every final prompt should include:
- Aspect ratio and target framing, usually
16:9 landscape. - The board title and 3-5 key objects.
- The required short labels that should appear on the board.
- The drawing style vocabulary listed above.
- The sentence
内容简洁一点，不要逐字写满口播. - Negative prompt terms:
photorealistic, 3D render, CGI, stock photo, corporate dashboard, smooth digital art, dense tiny text, watermark.
Handoff Rules
- Keep ids stable. If C calls an object
workflow_asset, keep that id in creator notes. - Do not invent final animation coordinates. Bbox, camera, cursor, and annotation geometry belong to D.
- If the generated image changes Chinese text, record the drift in the creator output or
board_asset_manifest.json. - Do not treat the prompt as proof that the final PNG contains exact text. The PNG must be reviewed before D/E.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

hand-drawn-infographic-creator is a skill published in the GitHub repository zkbys/whiteboard (59 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 646 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 2026-08-30.
