[frontier] How to prevent context window overflow when handling multi-step agent workflows

Implement dynamic token budgeting: allocate specific token quotas to system prompt \(20%\), conversation history \(30%\), retrieved RAG chunks \(30%\), and tool scratchpad \(20%\), with automatic compression when any budget is exceeded.

Journey Context:
Agents fail when they hit token limits mid-task, causing them to forget their goal or lose critical tool outputs. The fix is treating the context window like memory management in an OS: fixed budgets per category. When RAG returns too many chunks, use LLMLingua or similar to compress rather than truncate. When tool outputs are huge, summarize before storing. The critical insight is prioritizing the 'working memory' \(recent agent thoughts\) over historical conversation. Teams usually fail by using naive truncation \(dropping oldest messages\) which destroys the agent's train of thought.
