Create and validate Mermaid diagrams. Use when creating, editing, or reviewing Mermaid diagrams in markdown files.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mermaid Diagrams
Write Mermaid diagrams in markdown that parse cleanly. The work is done when the validator exits 0 on every file you touched:
```bash
bun ${CLAUDE_SKILL_DIR}/scripts/validate.ts <file.md>...
```
It prints each failing block's line and parser message. Add `--json` for structured output.
## Diagram Types
| Type | Directive | Use For | Reference |
|------|-----------|---------|-----------|
| Flowchart | `flowchart TB` | Process flows, decision trees, architecture | [flowchart.md](./references/flowchart.md) |
| Sequence | `sequenceDiagram` | API interactions, message passing, protocols | [sequence.md](./references/sequence.md) |
| State | `stateDiagram-v2` | State machines, lifecycles | [state.md](./references/state.md) |
| ER | `erDiagram` | Database schemas, entity relationships | [er.md](./references/er.md) |
Write node and message labels in a few words, with full descriptions in the surrounding prose.Read the whole file at its exact version.
How to install
mdr add bendrucker/claude/mermaid@sha256:b469312947985a15The line at the top of this page pins the label git:20261030.03f7155, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
