When AI agents see your test suite and acceptance criteria, they don't solve the problem ā they solve the tests.
Developer Farm is an open-source AI coding pipeline that makes metric gaming physically impossible through strict 4-layer isolation:
š Planning never sees execution results
š Execution never sees the test suite or rubric
š Verification doesn't know who wrote the code
š Retry feedback never leaks the scoring criteria
Built on LangGraph + local Ollama + Qwen models
