Brief
Context Hub is an open tool announced by Andrew Ng on 2026-03-09 that provides coding agents with up-to-date API documentation via a simple CLI (npm install -g @aisuite/chub). It prevents hallucinated parameters and outdated calls (Ng cites Claude Code using chat completions instead of the year-old responses API), lets agents annotate and store workarounds, and aims to enable shared agent learnings.
Why it matters
Andrew Ng announced Context Hub on 2026-03-09 as an open tool that gives coding agents up-to-date API documentation; install via npm: npm install -g @aisuite/chub and source on GitHub at github.com/andrewyng/context…
Key details
- Context Hub provides a simple CLI that agents can be prompted to use to fetch curated docs, addressing agents using outdated APIs and hallucinating parameters (example: Claude Code calling GPT-5.2 still used the older chat completions API instead of the newer responses API, which has been out ~1 year)
- Agents can annotate docs and save discovered workarounds for future sessions, with a long-term goal of agents sharing learnings community-wide; credits to Rohit Prasad and Xin Ye
