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 | $0.00026 | $0.03787 |
| Opus 5 | $0.00013 | $0.01894 |
| Sonnet 5 | $0.00005 | $0.00757 |
| Haiku 4.5 | $0.00003 | $0.00379 |
Grade A, and why
mermaid-diagram-specialist 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 12d 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-diagram-specialist — 0 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 Diagram Specialist
Overview
Purpose: Expert in creating comprehensive Mermaid diagrams for documentation, architecture visualization, and process mapping
Category: Tech Primary Users: tech-writer, architecture-validator, product-technical, tech-lead
When to Use This Skill
- Creating architecture documentation
- Visualizing workflows and processes
- Documenting data models (ERDs)
- Explaining sequence flows
- Creating state machines
- Documenting component relationships
- Creating decision trees
- Visualizing user journeys
Prerequisites
Required:
- Understanding of the system/process to document
- Access to technical specifications
- Knowledge of diagram type needed
Optional:
- Design system colors for consistency
- Existing documentation to reference
Input
What the skill needs:
- Process/system description
- Entities and relationships (for ERDs)
- Component interactions (for sequence diagrams)
- Architecture layers (for C4 diagrams)
- States and transitions (for state diagrams)
Workflow
Step 1: Diagram Type Selection
Objective: Choose appropriate diagram type for requirements
Available Diagram Types:
- Flowchart: Decision flows, algorithms, processes
- Sequence Diagram: API interactions, message flows
- ERD: Database schemas, entity relationships
- Class Diagram: Object-oriented design
- State Diagram: State machines, lifecycle
- Gantt Chart: Project timelines, schedules
- C4 Diagram: Architecture at different levels
- Pie/Bar Charts: Data visualization
- Git Graph: Version control flows
- User Journey: User experience flows
Decision Matrix:
- Process with decisions → Flowchart
- API/system interactions → Sequence Diagram
- Database structure → ERD
- System architecture → C4 Diagram
- Object relationships → Class Diagram
- State transitions → State Diagram
- Project timeline → Gantt Chart

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-diagram-specialist is an agent published in the GitHub repository nortonx/ai-tooling-free (1 stars, last pushed 28d ago), licensed MIT. It adds 26 tokens to every session and 3,787 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to mermaid-diagram-specialist, differing in 0 lines, and is treated as a copy.
