Dirac is an open-source AI coding agent that uses hash-anchored AST manipulation and parallel edits to achieve high accuracy while significantly reducing LLM API costs. It's interesting because it addresses the context degradation problem in large language models through precise, syntax-aware editing and multi-file batching.
