Modern Web Guidance feeds coding agents modern web APIs instead of 2019-era JavaScript patterns

Show HN: Get your coding agent off ~2019 JavaScript, onto modern web primitives

Modern Web Guidance is a skill and CLI tool that puts modern web practices and browser compatibility data into a coding agent's context. It covers 250 modern web features and 203 real development use cases, with local semantic search, guide lookup and scans for old patterns. Looking up guides for experimental or unstable APIs requires the developer's explicit consent.

Why it matters: It retrieves modern browser guidance per task and injects it into the agent's context, so generated code carries compatibility data and lightweight fallbacks.
