Score: 6.8/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 6)

D-Engine is a deterministic harness that applies LLM-generated SEARCH/REPLACE blocks to code via a shadow git worktree, gated by TypeScript compilation. It eliminates the token-expensive agentic loop for bounded edits, achieving 14–42× fewer tokens with equal quality on its benchmark.

Target audience: backend developers, full-stack developers using LLM-assisted coding
