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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00110 | $0.01873 |
| Opus 5 | $0.00055 | $0.00937 |
| Sonnet 5 | $0.00022 | $0.00375 |
| Haiku 4.5 | $0.00011 | $0.00187 |
Grade A, and why
mermaid-diagrams 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.
How it starts
The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mermaid diagrams
Create, validate, and export Mermaid diagrams for B2B SaaS workflows, architectures, and process visualizations.
Triggers
Invoke when user says:
- "Create a diagram for [process]"
- "Flowchart for [workflow]"
- "Mermaid diagram of [system]"
- "Architecture map for [product]"
- "Process map for [workflow]"
- "Visualize [process/system]"
- "Export diagram to Figma"
Do NOT invoke when:
- User wants a text-only process description (just write it)
- User wants a Google Slides presentation (use
create-gdrive) - User wants an infographic (use
linkedin-infographics)
Supported diagram types
| Type | Mermaid syntax | Best for |
|---|---|---|
| Flowchart | graph TD / graph LR |
Processes, decision trees, user flows |
| Sequence | sequenceDiagram |
API flows, user interactions, handoffs |
| Class | classDiagram |
Data models, system architecture |
| State | stateDiagram-v2 |
Status workflows, lifecycle stages |
| Gantt | gantt |
Timelines, project plans, launch schedules |
| Mindmap | mindmap |
Brainstorming, topic clustering |
| Quadrant | quadrantChart |
Positioning maps, priority matrices |
Process
Step 1: Identify diagram type
Match the user's need to the best Mermaid type:
- "How does X flow?" → Flowchart
- "What happens between A and B?" → Sequence diagram
- "What are the states of X?" → State diagram
- "Show the timeline for X" → Gantt chart
- "Map out the concepts" → Mindmap
- "Plot X vs Y" → Quadrant chart
Step 2: Draft the diagram
Write valid Mermaid syntax. Follow these rules:
- Use descriptive node IDs (not single letters)
- Keep labels concise (under 40 characters)
- Use subgraphs to group related nodes
- Apply consistent direction (TD for vertical, LR for horizontal)
- Use appropriate link styles (solid for primary flow, dotted for optional)
Step 3: Validate
Before delivery:
- Syntax renders without errors
- All nodes are connected (no orphans)
- Labels are readable at normal zoom
- Direction is logical (top-to-bottom or left-to-right)
- Subgraphs are labeled
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-diagrams is a skill published in the GitHub repository matteotitta/genesys-skills (36 stars, last pushed 1mo ago), licensed MIT. It adds 110 tokens to every session and 1,873 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.
