Dear friends,
I’m thrilled to announce Context Hub, a new tool to give to your coding agents the API documentation they need to write correct code. If you’re building AI systems using modern technologies, your coding agent will often use outdated APIs, hallucinate parameters, or not even know about the tool it should be using. This happens because AI tools are rapidly evolving, and coding agents were trained on old data that does not reflect the latest tools. Context Hub, which is designed for your coding agent to use (not for you to use!) provides the context it needs. It also accepts automatic agentic feedback to help your coding agents improve over time.
For example, Claude Opus 4.6, possibly the best coding model currently, has a knowledge cutoff date of May 2025. When I ask it to write code to call OpenAI's GPT-5.2, it uses the older OpenAI chat completions API (client.chat.completions.create) rather than the newer responses API (client.responses.create) that OpenAI recommends. Even though the newer API is a year old, there's a lot more data that Opus was trained on that uses the older interface. It also has no idea about the existence of Nano Banana, which was released in August 2025. More generally, I’ve seen coding models fail to make correct API calls to Gemini and many database services (even popular ones, when I use less common parameter choices), or just not know about a particular tool I want.
