Context Is the New Code — Patrick Debois, Tessl
Overview
This talk proposes that context is the new code in software development, shifting focus from writing explicit code to generating and managing contextual information for AI agents. It outlines a "context development life cycle" analogous to the DevOps infinity loop, encompassing generation, testing, distribution, and observation of context. The core idea is that by engineering and refining context, developers can significantly improve the performance and reliability of AI-driven development processes.
Who should watch
- AI engineers and developers working with coding agents.
- Product Managers and builders evaluating AI development workflows.
- Anyone interested in improving the reliability and effectiveness of AI-generated code.
- Those facing challenges with prompt engineering and agent consistency.
Key takeaways
- Context generation involves moving beyond simple prompting to creating reusable instructions, incorporating external documentation, and even using spec-driven development for agents.
- Testing context is crucial, moving from basic linting and validation to more sophisticated checks that ensure an agent understands and correctly applies the provided context.
- Distributing context can be achieved through version-controlled repositories or dedicated registries for reusable "skills" or context packages, akin to software libraries.
- Observing context involves analyzing agent logs and production feedback to identify areas for improvement and to create new context or tests based on real-world usage.
- The reliability of AI agents is heavily dependent on the quality of the context provided, making context engineering as important as the AI models themselves.
- Testing AI-generated code can involve executing it in sandboxed environments to simulate real-world scenarios and catch potential issues before deployment.
- A context development life cycle can be applied at individual, team, and organizational levels to scale improvements and foster a feedback loop for continuous refinement.
- *The LLM is just the engine. If you give the engine the wrong fuel, which is context, they're not going to perform.*
Notable quotes
Patrick Debois suggests that context is the new code because it is being generated.
