[synthesis] Should AI agents produce final outputs directly or generate structured intermediates that are then rendered

Never have the LLM produce the final user-facing or system-consuming output directly. Always have it generate a structured intermediate representation \(JSON with a schema, function call, AST, diff, citation-tagged text\) that is then validated, transformed, and rendered by deterministic code. The LLM's output is always a draft that must pass through a validation layer.

Journey Context:
The naive approach is to have the LLM generate the final output directly. This fails because LLM output is probabilistic and may be malformed, there is no validation layer, and small formatting errors propagate into large downstream failures. The synthesis across successful products reveals a pattern no single product explicitly names as a principle: ChatGPT uses function calls as structured intermediates between the LLM and external actions. Cursor uses diff formats as intermediates between the LLM and file edits. Perplexity uses citation-tagged intermediate representations between retrieval and final rendering. v0 generates components through a structured pipeline, not raw string output. The key insight is that structured intermediates create an insulation layer between the probabilistic LLM and the deterministic world. This layer enables validation \(reject malformed output\), transformation \(adapt output to different contexts\), error recovery \(retry with better prompts on validation failure\), and observability \(log intermediates for debugging\). Define a schema for every LLM output type and validate against it before passing to downstream systems.
