Context Engineering

Design Your AI Context Window

Structure the full context that drives your AI system — system prompts, RAG injection, memory management, and multi-agent handoffs.

Pick a pattern

Choose the context layer that fits your AI system. Start with System Prompt — then add RAG, Memory, or Tools on top.

Fill the fields

Describe your AI system's role and rules. Not sure what to write? Click Try sample on any pattern to load a real example.

Copy & deploy

Paste the output as your system prompt. Markers like {{CONTEXT}} are injection points — replace them in your code with real data at runtime.
