Prompts in AGNT5 are versioned artifacts — not strings hardcoded inside an Agent’s source. They’re first-class objects you can iterate on, reference from an Agent, roll back, and compare across versions without redeploying code.

You’ll find Prompts under Improve → Prompts in Studio.

The point of lifting prompts out of code is to make prompt iteration a measurement problem, not a deployment problem. You change a Prompt version, run an Experiment against a Dataset, compare scores, and ship the new version if it’s better — all without pushing a commit.

A deeper guide is in progress. For how Prompts compose with Agents, see the Agents foundation.
