Prompting for reliable agents
Five patterns that cut hallucination in production.
A dark-first design language for Fellow Intelligence — learning, product, and studio — carried by bold grotesque type, one voltage-yellow action, and a single grainy electric-blue glow.
Two accents do all the talking. Voltage yellow is the single loud action; blue carries links, focus and the glow. Surfaces and text resolve by mode — toggle above to see both.
Brand & AccentEach accent is a small role-based ramp so you can reach for the right tone by intent and by background. tint / soft adapt to the surface via color-mix; link / hover resolve by mode (blue text brightens on charcoal for legibility). Toggle dark/light above to see them shift.
Seven approved compositions of the glow. All are mode-aware: in light mode the sink fades to transparent (no dark smudge on paper) and the whole bloom drops to 55% opacity. Toggle dark/light above to compare.
Live from Adobe Fonts: ITC Avant Garde Gothic Pro for display; Scandia for body/UI; Nexa for technical labels — a geometric label voice in place of the previous monospace. Thai display uses Bai Jamjuree; Thai body uses Proxima Nova Thai Looped.

One atmospheric moment per view — a radial blue bloom with grain, behind the copy. Never a button, never a background wash.
Buttons, form controls, chips, tabs and navigation atoms — the reusable kit every surface is built from. Toggle dark/light above; all states resolve by mode.
Buttons · variantsSystem messaging — inline alerts, toasts, modals, drawers, empty and loading states. Semantic color carries meaning; the glow never appears here.
Inline alerts · info / success / warning / errorThis removes the agent and its evaluation history. This action can't be undone.
Build your first agent to start evaluating and shipping. Templates make it a two-minute job.
The content library — testimonials, case studies, articles, people, lists and FAQs. All sit on surface with a hairline; one glow card maximum per view.
