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 | $0.00076 | $0.01650 |
| Opus 5 | $0.00038 | $0.00825 |
| Sonnet 5 | $0.00015 | $0.00330 |
| Haiku 4.5 | $0.00008 | $0.00165 |
Grade A, and why
excalidraw-crafter 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 9d 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excalidraw Crafter
This skill empowers Claude to author raw, editable .excalidraw whiteboard files. Because Excalidraw relies on a strict JSON payload describing coordinates, dimensions, types, and groupings, you must structure the data carefully rather than relying on Markdown text.
When to Use This Skill
- The user asks for a flowchart, architecture diagram, wireframe, or whiteboard layout.
- The user specifically mentions "Excalidraw" or "editable whiteboard file."
- The output needs to be a file that the user can later move objects around in visually via
excalidraw.comor a VS Code extension, rather than a frozen image or a strict radial mind map.
🛑 REQUIRED INTERACTIVE WORKFLOW (DO NOT SKIP)
Under no circumstances generate the JSON code immediately if the user hasn't explicitly specified a layout type. When a user requests an Excalidraw diagram, you MUST STOP and present the following 5 options with their descriptions, asking the user to choose one:
- 🌳 Árbol Jerárquico Horizontal: Nodo raíz situado a la izquierda con ramas que se abren secuencialmente hacia la derecha. (Ideal para: desglosar temarios de cursos, organigramas o índices de libros).
- 🌟 Mapa Mental Radial: Un núcleo central en medio del lienzo del que orbitan las ideas principales y secundarias en forma de estrella. (Ideal para: lluvia de ideas creativas, conceptos no lineales y explorar conexiones orgánicas).
- ⬇️ Flujo Descendente (Flowchart): Cajas y rombos geométricos conectados de arriba hacia abajo en forma de cascada. (Ideal para: diagramas de flujo, embudos de conversión, algoritmos o paso a paso de procesos).
- 🗂️ Tablero en Matriz (Grid / Kanban): Distribución tipo tarjetas alineadas en columnas y filas exactas, sin conectores complejos. (Ideal para: comparativas, dashboards estructurales, o agrupar conceptos por categorías estrictas).
- 🐟 Diagrama Raspa de Pez (Fishbone / Timeline): Una espina dorsal horizontal (eje principal o temporal) de la que salen ramas oblicuas hacia arriba y abajo. (Ideal para: análisis de causa, líneas de tiempo o hitos secuenciales).
What ships with it
3 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.

excalidraw-crafter is a skill published in the GitHub repository smartbrainactivity/visual-diagramming-export (3 stars, last pushed 6mo ago), licensed MIT. It adds 76 tokens to every session and 1,650 once invoked, about $0.0004 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.
