[synthesis] How should AI agents allocate limited context window space across different types of information

Treat context as a finite budget with explicit allocation tiers: \(1\) system instructions and tool definitions — non-negotiable, always included; \(2\) current task description and most recent observations — high priority; \(3\) retrieved code snippets — medium priority, relevance-ranked with a cap; \(4\) conversation history — compress aggressively, never let it crowd out task-relevant context. When the budget is exceeded, compress the lowest-priority tier first using summarization, not truncation.

Journey Context:
The common failure mode is uncontrolled context growth — conversation history accumulates, tool outputs pile up, and eventually the model loses track of the actual task. The synthesis across products reveals a consistent pattern that no single product documents holistically. Anthropic's documentation recommends prioritizing recent and relevant context. Cursor's observable behavior suggests it truncates older conversation turns while preserving code context. Aider's repo map is itself a form of context budgeting — compressing the codebase into a structural summary. The key insight that only emerges from cross-product comparison: not all context tokens are equal. A single line of current code state is worth more than paragraphs of earlier conversation about that code. Conversation history is the lowest-value context because it is redundant with the code state — if the code is in the context, you don't need the conversation that produced it. Implement explicit budgeting with caps per tier.
