explainme skillA

explainme is agent-read markdown (skill) from jdanigo/hydraia: Explain a codebase, subsystem, or PR to a human — visually and verifiably. Turns real code structure into a polished, validated, explorable standalone HTML map (architecture, workflow, sequence, data-flow, or lifecycle/state) with inline SVG, dark/light themes, guided walkthrough chapters, source-pinned nodes, and PNG/SVG/WebM export. Use for onboarding, "how does this system work / how does this flow work", visual PR/architecture review, or converting/beautifying Mermaid. In Hydraia it is groun.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add jdanigo/hydraia/explainme@v0.1 (hydraia)
Exact content
mdr add jdanigo/hydraia/explainme@sha256:66748ffd1cd017a4

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
