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 | $0.00111 | $0.01604 |
| Opus 5 | $0.00056 | $0.00802 |
| Sonnet 5 | $0.00022 | $0.00321 |
| Haiku 4.5 | $0.00011 | $0.00160 |
Grade A, and why
excalidraw-visual-designer 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 11d 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.

Excalidraw Visual Designer
Core Workflow
Use the in-app browser and the existing Excalidraw tab when present.
- Read and follow the
browser:control-in-app-browserskill before controlling the browser. - Claim the existing
https://excalidraw.com/tab instead of opening a duplicate. - Keep the browser visible when the user is reviewing the drawing.
- Prefer Excalidraw clipboard JSON import over manual dragging for complex layouts.
- After each substantial visual change, take a screenshot and inspect it for legibility, overlap, and visual quality.
- Finalize with the Excalidraw tab kept as
deliverable.
Output Types
Choose the structure by intent:
- Diagrams and flowcharts: use editable Excalidraw rectangles, diamonds, arrows, swimlanes, labels, and grouping.
- Architecture or system maps: use consistent containers, call paths, data stores, boundaries, and directional arrows.
- Infographics and teaching visuals: combine editable text/cards with simple charts, numbered sections, icons, and callouts.
- Product or object explanation graphics: use clean SVG image elements for polished product/object illustrations, then layer editable labels and arrows.
- Whiteboard sketches: keep a looser Excalidraw style, but still preserve alignment, spacing, and clear reading order.
- Promotional materials and posters: use structured panels, headline, offer, main visual, information blocks, and CTA.
Use editable Excalidraw text and shape elements for copy, labels, arrows, process structure, prices, CTA, and layout blocks. Use embedded SVG image elements only when a detailed illustration would look crude if built from primitive Excalidraw shapes.
Visual Construction Rules
- Use a constrained canvas area or frame-like boundary for presentation graphics.
- Establish a clear reading path before placing decorative details.
- Keep text editable wherever future changes are likely.
- Prefer simple, recognizable symbols over overdrawn illustration.
- Use polished SVG image elements for food, people, products, devices, and other high-detail visuals.
- Keep stroke weights consistent within each visual region.
- Avoid floating labels; connect labels to targets with lines or place them in contained cards.
- Preserve existing user-approved areas when revising one problematic region.
What ships with it
1 file 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.
