Original: Coding Agents Don’t Need Bigger Context Windows — They Need a Context Compiler
Short summary
Coding agents fail when they treat prompt construction as retrieval — gathering more files and hoping the model sorts it out. As context grows, irrelevant code competes for attention and agents degrade their own memory mid-task. The author proposes treating prompt construction like a compiler that actively decides what to keep, reduce, or discard.
- •Coding agents degrade when context windows fill with irrelevant code
- •Forgetting is often degraded context, not a model limitation
- •Proposed solution: a context compiler that curates what enters the prompt
