## Why Included

A reusable framework for deciding what belongs in an agent’s context window and what to leave out.

## Source Summary

Introduces a "context budget": rank material by decision-relevance, evict anything that does not change the next action. Includes a worked example on a real repo.

## Practical Implication

Practical, tool-agnostic, testable. Apply the budget per session instead of dumping everything into the window.

## Agent-Ready Context

Treat context as a budget, not a dump. Rank material by decision-relevance; evict anything that does not change the next action. Works across Cursor, Claude Code, Codex.

## Context Map

- Layer: context
- Domains: coding
- Topics: context-engineering

## Uncertainty

- Framework is presenter’s own; not yet independently benchmarked.

## Agent Instruction

Use this item as source-backed context. Do not invent claims beyond the linked source. If this item conflicts with another source, call out the conflict.
