Providing an entire repository dump to a coding agent increases noise, induces hallucinations, and dilutes attention. Effective AI coding relies on tight context budgets and bounded contracts.
Do not feed hundreds of unrelated files into the agent prompt. Provide only:
- The specific file to modify;
- The public interface signatures of direct callers/callees;
- The automated test file defining the desired behavior.
Natural language instructions like “make the API cleaner” lead to unpredictable rewrites. Instead, specify:
- Input types and output formats;
- Permitted dependencies and standard library constraints;
- Failure cases and explicit exception types;
- The exact verification command to run.
Ensure the agent can run local feedback loops using fast tools such as uv documentation and pytest documentation. A sub-second test loop allows the agent to iterate and fix errors autonomously before human review.
Always inspect git diffs to ensure the agent did not delete unrelated comments, introduce unpinned dependencies, or modify shared global state.
