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 | $0.00113 | $0.03564 |
| Opus 5 | $0.00056 | $0.01782 |
| Sonnet 5 | $0.00023 | $0.00713 |
| Haiku 4.5 | $0.00011 | $0.00356 |
Grade A, and why
excalidraw-generator 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 5d 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 — 502 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excalidraw Diagram Generator
Create complete, valid .excalidraw.json files that users can directly open at excalidraw.com.
Core Capabilities
Diagram types supported:
- Flowcharts - Process flows, decision trees, workflows
- Architecture Diagrams - System architectures, network topologies, component diagrams
- UML Diagrams - Class diagrams, sequence diagrams, use case diagrams
- Mind Maps - Hierarchical concept maps, brainstorming diagrams
Two visual styles:
- Professional Mode (default): Clean, polished diagrams for technical documentation
- Hand-drawn Mode: Sketch-style diagrams for brainstorming and informal use
Quick Reference
JSON Schema
{
"type": "excalidraw",

Coordinate System
- Origin: Top-left corner (0, 0)
- X-axis: Increases rightward
- Y-axis: Increases downward
- Unit: Pixels
Grid-Based Layout System
Use a 20px grid for alignment:
GRID_UNIT = 20
COLUMN_WIDTH = 200 # Element + gap
ROW_HEIGHT = 150 # Element + gap
Position formula:
x = START_X + (column * COLUMN_WIDTH)
y = START_Y + (row * ROW_HEIGHT)
Recommended START_X = 50, START_Y = 100
Standard Element Sizes
| Element | Width | Height | Use Case |
|---|---|---|---|
| Small box | 120 | 60 | Labels, simple steps |
| Standard box | 160 | 80 | Process steps |
| Large box | 200 | 100 | Detailed nodes |
| Wide box | 240 | 80 | Long text |
| Diamond | 100 | 100 | Decision points |
| Circle | 80 | 80 | Start/End nodes |
Text Calculations (CRITICAL)
Text Height Formula
textHeight = fontSize × lineHeight × numberOfLines
= fontSize × 1.25 × numberOfLines
Examples:
- 1 line, fontSize 20: 20 × 1.25 × 1 = 25px
- 3 lines, fontSize 14: 14 × 1.25 × 3 = 52.5px ≈ 53px
- 12 lines, fontSize 15: 15 × 1.25 × 12 = 225px
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-generator is a skill published in the GitHub repository kv0906/pm-kit (133 stars, last pushed 2mo ago), licensed MIT. It adds 113 tokens to every session and 3,564 once invoked, about $0.0006 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.
