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…
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
# Explainme — visual, verifiable code explanation Explain a codebase to a human as a **self-contained, interactive HTML map** compiled from a small typed JSON specification. The deterministic CLI validates every artifact before delivery and refuses to ship one that is not geometrically clean and semantically faithful — so the diagram never invents topology. Static output is the default; enable motion only for a demo or presentation. **This is a vendored + rebranded build of [Archify](https://github.com/tt-a1i/archify) (MIT).** The MIT `LICENSE`, `THIRD_PARTY_NOTICES.md`, and the upstream attribution above are kept as required. The engine (schemas, renderers, viewer, validator) is upstream's; Hydraia adds the codegraph grounding and the onboarding framing below. ## Hydraia grounding — codegraph is the topology source (read first) Do NOT hand-guess the system's structure. In Hydraia the topology comes from **codegraph** (the verified code knowledge graph), and Explainme renders it: 1. Query codegraph for the subsystem in scope — components/modules, call edges, entry points, storage/transports, blast radius (`codegraph_explore`, callers/callees/impact). That is the ground truth. …

How to install
mdr add jdanigo/hydraia/explainme@sha256:66748ffd1cd017a4The line at the top of this page pins the label v0.1 (hydraia), 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.
