Overview

Prompt composition attaches reusable prompt versions to a skill version in a deterministic order. Prompts hold authored content; skills hold execution configuration and references to the prompt versions they use.

What you get

• Reusable prompt objects with independent version history.
• Skill versions that expose promptComposition for ordered prompt attachments.
• Preview and run traces that show the rendered prompt and composition metadata.

Core primitives

• Prompts: authored prompt objects addressed by promptKey.
• Prompt versions: immutable content versions that can be published.
• Skill prompt composition: ordered references attached through replacePrompts.
