Most AI coding tools fail not because the model is weak. They fail because the context is dirty. Yesterday's failed test pollutes today's refactor. One noisy file steers the whole conversation. The fix is not a better prompt. The fix is isolation.
This article shows how to run a small, reproducible context isolation layer for AI-assisted code changes. The workflow uses MonkeyCode's open source project, its free model access, and its free server option. You can apply the same principles to any tool.

The Real Problem Is Not Tokens
Free tiers give you plenty of tokens. The bottleneck is relevance. When an AI agent receives a 200-file repository, it does not read every file. It retrieves fragments. Those fragments are often stale, duplicated, or irrelevant.
