What it does
Mermaid Diagrams is an agent skill from hoodini/ai-agents-skills. Create diagrams and visualizations using Mermaid syntax.

Triggers on Mermaid, flowchart, sequence diagram, class diagram, ER diagram, Gantt chart, diagram, visualization.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Diagrams. It works with Mermaid. The repository describes itself as: 🧠 AI Agent Skills Repository - A curated collection of specialized skills for AI coding agents (Claude Code, GitHub Copilot, Cursor, Windsurf). Created by Yuval Avidani using…
When your agent uses it
- Generating flowcharts
- Sequence diagrams
- Entity-relationship diagrams
- Any visual documentation
Example prompts
- “/mermaid-diagrams”
Requirements
- Node.js
- Docker
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Direction: Use TD (top-down), LR (left-right), BT (bottom-top), RL (right-left)
- Comments: Use %% for comments
- Quotes: Use quotes for labels with special characters: A["Label with (parentheses)"]
- Line breaks: Use for multi-line labels
What it can do on your machine
Read from SKILL.md and the folder at commit f7a43d8. 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 (its code samples are mermaid and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
mermaid.js.orgmermaid.live
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
Mermaid Diagrams loads about 1.9k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 112 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 112 words (~1,895 tokens).
“Create diagrams and visualizations using Mermaid markdown syntax.”
