# Eva

> The Protocol and Blueprint creation assistant.

Eva is the creation assistant inside Atlas. Eva translates natural-language intent into a Protocol or Blueprint draft.

Eva does not measure. It operates in the creation layer only: reading intent, surfacing nuance candidates, and proposing configurations for human review.

## What Eva does

**Protocol drafting.** Describe what you want to measure. Eva returns a labelled, weighted nuance set with C×B×I tags and a zero-shot fidelity estimate.

**Nuance refinement.** Edit labels or descriptions. Eva adjusts the spectral configuration to match the new intent without requiring a full redraft.

**Fidelity diagnosis.** Eva flags nuances where the initial draft shows low fidelity and suggests exemplars or contrastive pairs to strengthen them.

**Blueprint assembly.** Select Protocols from the library or draft new ones. Eva checks for nuance overlap and interaction coverage gaps.

## Limits

Eva is not the measurement. Eva generates candidate configurations. Every Protocol requires a human publish decision before it becomes callable from the API.
