Context Window Budget Allocator

I'm building a {{application_type}} with a {{model_name}} backend ({{context_window}} token context window).\n\nMy context needs:\n- System prompt: {{system_prompt_summary}}\n- User query: variable length\n- Retrieved documents: {{retrieval_description}}\n- Conversation history: {{history_policy}}\n- Tool call results: {{tool_results_description}}\n\nDesign the token budget allocation. For each component:\n1. Allocate a fixed or proportional token budget\n2. Define the compression strategy when it exceeds budget\n3. Set the priority for when total context exceeds the window\n4. Specify the format (raw text, XML tags, JSON, markdown)\n\nInclude a fallback strategy for edge cases where a single component exceeds 50% of the window.
