What it does
Visualizing With Mermaid is an agent skill from rileyhilliard/claude-essentials. Creates professional Mermaid diagrams with semantic styling and visual hierarchy. Use when creating flowcharts, sequence diagrams, state machines, class diagrams, or architecture visualizations.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/color-palettes.md` and `references/examples.md`).
It sits in Development, covering Diagrams. It works with Mermaid. The licence is MIT.
When your agent uses it
- Creating flowcharts
- Sequence diagrams
- Architecture visualizations
Example prompts
- “Use the visualizing-with-mermaid skill to create professional Mermaid diagrams with semantic styling and visual hierarchy”
- “/visualizing-with-mermaid”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Visual hierarchy over decoration - Color/size guide the eye to what matters
- Semantic color - Colors have meaning (grouping, state, criticality)
- Simplicity over completeness - 80% clearly beats 100% confusingly
- 7-12 nodes max - Human working memory limit; break larger systems into drill-downs
What it can do on your machine
Read from SKILL.md and the folder at commit 3a67a01. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Visualizing With Mermaid loads about 624 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 248 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Creates professional Mermaid diagrams with semantic styling and visual hierarchy. Use when creating flowcharts, sequence diagrams, state machines, class diagrams, or architecture visualizations.
Mermaid Diagrams
Default: Dark mode colors from references/color-palettes.md.
Choosing Diagram Type
| Concept | Diagram Type |
|---|---|
| Process flows, decisions | Flowchart (TB direction) |
| API calls, message passing | Sequence diagram |
| Lifecycle states | State diagram |
| Data models, relationships | Class diagram or ERD |
| System architecture | Flowchart with subgraphs (LR direction) |
Core Principles
- Visual hierarchy over decoration - Color/size guide the eye to what matters
- Semantic color - Colors have meaning (grouping, state, criticality)
- Simplicity over completeness - 80% clearly beats 100% confusingly
- 7-12 nodes max - Human working memory limit; break larger systems into drill-downs
Quick Styling Guide
Do:
- Use fills to group related components
- Highlight critical paths with stroke width
- Different shapes = different component types (cylinders for DBs, diamonds for decisions)
- Keep labels to 1-4 words; use
<br/>for longer
Don't:
- Pure black (
#000000) - too harsh, use dark gray - Saturated background colors - tire the eyes
- More than 5 colors per diagram
- Low-contrast combinations
Shape Semantics
- Rectangles: Services, processes
- Rounded rectangles: APIs, interfaces
- Circles: Start/end points, external systems
- Diamonds: Decision points
- Cylinders: Databases
- Hexagons: Queues, message brokers
Layout
LR (left-to-right): Pipelines, architecture diagrams TB (top-to-bottom): Hierarchies, decision flows
Use subgraphs for: deployment boundaries, logical layers, team ownership, trust boundaries.
Resources
- Color palettes: See references/color-palettes.md
- Pattern examples: See references/examples.md for architecture, state machines, data flows, ERDs
Workflow
- Purpose - What decision/understanding should this enable?
- Type - Choose based on what you're showing
- Structure - Identify components, relationships, groupings
- Style - Apply semantic colors, highlight critical paths
- Review - Can someone understand it in 10 seconds?
