Specs are editable documents, so they are better for interacting with LLMs.

A powerful pattern is editable inputs to LLMs

Context that you intentionally factor out to be shareable in other tasks, vs implied context of "messages that came before in this thread"

Specs that the user and LLM are updating and tweaking is accumulating state as it goes on, with feedback and curation throughout.

The continuous curation keeps it higher quality.

The append-only nature of chats is really limiting.

A conversation that goes off the rails you have to restart.
