axton-obsidian-visual-skills is a set of Claude Code skills that turns text descriptions into Canvas, Excalidraw, and Mermaid diagrams for Obsidian. It is intended for people who want to create flowcharts, mind maps, and other visual notes from text, and the catalogue includes its three skills and plugin.
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 | $0.00057 | $0.02126 |
| Opus 5.5 | $0.00023 | $0.00850 |
| Sonnet 5.5 | $0.00011 | $0.00425 |
| Haiku 4.5 | $0.00006 | $0.00213 |
Grade A, and why
mermaid-visualizer 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 1mo 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.
This is a copy
100% identical to mermaid-visualizer — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Mermaid Visualizer
Overview
Convert text content into clean, professional Mermaid diagrams optimized for presentations and documentation. Automatically handles common syntax pitfalls (list syntax conflicts, subgraph naming, spacing issues) to ensure diagrams render correctly in Obsidian, GitHub, and other Mermaid-compatible platforms.
Quick Start
When creating a Mermaid diagram:
- Analyze the content - Identify key concepts, relationships, and flow
- Choose diagram type - Select the most appropriate visualization (see Diagram Types below)
- Select configuration - Determine layout, detail level, and styling
- Generate diagram - Create syntactically correct Mermaid code
- Output in markdown - Wrap in proper code fence with optional explanation
Default assumptions:
- Vertical layout (TB) unless horizontal requested
- Medium detail level (balanced between simplicity and information)
- Professional color scheme with semantic colors
- Obsidian/GitHub compatible syntax
Diagram Types
1. Process Flow (graph TB/LR)
Best for: Workflows, decision trees, sequential processes, AI agent architectures
Use when: Content describes steps, stages, or a sequence of actions
Key features:
- Swimlanes via subgraph for grouping related steps
- Arrow labels for transitions
- Feedback loops and branches
- Color-coded stages
Configuration options:
layout: "vertical" (TB), "horizontal" (LR)detail: "simple" (core steps only), "standard" (with descriptions), "detailed" (with annotations)style: "minimal", "professional", "colorful"
2. Circular Flow (graph TD with circular layout)
Best for: Cyclic processes, continuous improvement loops, agent feedback systems
Use when: Content emphasizes iteration, feedback, or circular relationships
Key features:
- Central hub with radiating elements
- Curved feedback arrows
- Clear cycle indicators
3. Comparison Diagram (graph TB with parallel paths)
Best for: Before/after comparisons, A vs B analysis, traditional vs modern systems
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.

mermaid-visualizer is a skill published in the GitHub repository axtonliu/axton-obsidian-visual-skills (3,663 stars, last pushed 4mo ago), licensed MIT. It adds 57 tokens to every session and 2,126 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to mermaid-visualizer, differing in 4 lines, and is treated as a copy.
