Eval Labs identity is product infrastructure. It should make the platform feel precise, trustworthy, calm, proprietary, and inspectable.

What this section is for

This section records how Eval Labs should look, sound, and present itself across:
  • the public documentation site
  • internal Canon notes
  • screenshots and examples
  • product UI references
  • employee-facing training material
  • future marketing or launch surfaces
The goal is not brand theater. The goal is consistency.

Core identity statement

It exists to make Lucia better at:
  • intent recognition
  • emotional containment
  • operational judgment
  • tone calibration
  • truth-state discipline
  • reviewer-guided improvement

Brand principles

1. Precise over flashy

Eval Labs should feel like a serious evaluation environment, not a hype site.

2. Warm over sterile

The platform evaluates human-facing AI behavior. The identity should feel calm and human, not cold or academic.

3. Proprietary over generic

Eval Labs is not a clone of generic eval tooling. It is Lucia-native behavioral judgment infrastructure.

4. Source-truth over sales copy

Documentation should explain what is true, what is live, what is deferred, and what is being tested.

Current identity frame

The Eval Labs landing page uses a Mintlify frame with tracked light- and dark-mode assets:
The shared style.css supplies the light/dark visibility helpers; the MDX owns the frame, caption, asset paths, and accessible alternative text.
