Context Engineering
Overview
Core principle: Context is a finite resource with diminishing returns. Find the smallest high-signal token set, not the largest.
200K tokens is shared space: system prompt + conversation history + your processing. As context grows, performance degrades predictably.
When to Use
- Session > 30 minutes or 50k+ tokens
- Instructions being ignored or forgotten
- Repeated clarifications needed
- Planning multi-agent workflows
- Preparing handoffs between sessions
