MHProto 0.8.0-preview.0

← Getting started

Published 2026-10-03 as a development preview on the npm next channel.

MHProto keeps behaviour, API contracts, examples and verification checks in your repository, with a shared browser view for humans and scoped context for agents.

• Browse feature pages, endpoints and linked types; attach design references.
• Compare iterations and keep evidence linked to contract rules and examples.
• Scaffold a project and install five skills for Codex, Claude or both.
• Retrieve scoped context and run structured checks with stale-evidence detection.
• Export a portable browser preview with diagrams, attachments and notices.
• Render diagrams with source-built Mermaid 12.1.0 and patched dependencies.

Node 22/24 on Linux/macOS are tested targets. Windows and non-Chromium browser flows remain unverified. This preview supports a documented OpenAPI 3.1/JSON Schema subset, and check results are evidence rather than a proof of correctness.
