Can I use this to generate links for local files?

Yes, you can pipe the contents of local .mmd files into the encoder to generate shareable URLs instantly.

Which Mermaid URL formats are supported?

The skill supports the pako-compressed format used by mermaid.live and the base64-encoded format used by the amp CLI.

Is an internet connection required for decoding?

No, the decoding and encoding logic is performed locally using the pako and base64 libraries.

How does this enhance the Claude Code experience?

It allows Claude to provide you with immediately clickable visualization links for any diagrams it generates during a coding session.

What is the difference between pako and base64 modes?

Pako uses compression to handle large diagrams within URL character limits, primarily for mermaid.live, while base64 is a direct encoding used by specific CLI tools.

Learning & Documentation

Encodes and decodes Mermaid diagram source code to and from shareable URLs for mermaid.live and amp CLI.

About

This skill provides a specialized utility for managing Mermaid.js diagrams by translating between raw source code and compressed URL formats. It supports both the pako-compressed strings used by the mermaid.live editor and the base64-encoded formats utilized by the amp CLI, allowing developers to quickly generate shareable links or extract source code from existing diagram URLs. This is particularly useful for documentation workflows, architectural reviews, and bridging the gap between local development and web-based visualization tools.

Key Features

Support for amp CLI base64 encoding formats
2 GitHub stars
Stream-based CLI usage for pipe-friendly workflows
Support for mermaid.live pako compression standards
Bidirectional conversion between Mermaid source and URLs
Automatic JSON handling for diagram data wrapping

Use Cases

Automating the generation of diagram links within documentation pipelines
Extracting raw diagram logic from a mermaid.live URL for local editing
Converting local .mmd files into shareable links for team reviews
