Designing trust into an AI agent.
Meet Zelda, Stell's reliable AI agent.
I designed Zelda's presence throughout Stell, an AI-native platform for aerospace systems engineering, from how it surfaces suggestions to how it hands control back to the engineer across requirements, evidence, and traceability. Precise, legible, and built to earn trust in situations where making a mistake isn't an option.
Zelda notices, the engineer decides
Without any prompting, Zelda flags a requirement with no linked evidence records and offers to help find related ones. Each suggestion comes with its reasoning, and nothing gets linked until the engineer reviews and confirms.
