Score: 7.5/10 (Innovation: 7, Technical: 7, Documentation: 9, Utility: 7)

TNL (Typed Natural Language) introduces a structured, schema-based contract format for coding agents, moving beyond ephemeral plan-mode conversations to persistent, machine-checkable feature specifications. It combines Karpathy's insights on agent confusion and structured Markdown into a practical workflow that demonstrably improves LLM coding accuracy. The A/B evaluation data and meta-usage of the tool itself strengthen its credibility.

Target audience: backend devs, devops, ai-ml engineers
