Prompts Manager

A prompt is one of the platform's universal node types rather than a settings row, so it carries an owner, a sharing scope and the same row-level security as every other entity — and gets the node card, the action menu and access management without special-casing. Each prompt holds more than its text: declared variables, input and output schemas, a tool policy, guardrails and an evaluation rubric, across seven prompt types. Every runtime that uses prompts — agent instructions, retrieval synthesis, approval gates, slide generation — stores a pointer to the saved prompt and resolves it through one shared primitive, so editing the prompt changes behaviour everywhere it is referenced without touching a flow. A prompt can pin the model it runs against, and forking records the parent rather than overwriting in place.
