Context-window optimization is becoming essential for production AI agents

Context windows are a scarce resource for production agents
The post argues that agents should not blindly dump everything into context. Long histories waste tokens, slow responses, and can hurt performance.
Practical rules
- Keep only the most relevant recent information
- Summarize or drop older conversation history
- Load tools and skills only when needed
- Prefer structured context over long free text
- Track context size in production
The accompanying diagram explains that the context window has limited memory: the model remembers recent exchanges, the current topic, and important details, but forgets older messages and previous instructions once they fall out of window.
