Falcon author's "design harness": an agent-native design system for designing with agents
round · x · 2026-11-12
Ahmed Saleh, author of Falcon, argues that design.md files, skill files and prompt engineering have failed to produce meaningfully better AI-designed interfaces. His answer: the design harness, an opinionated schema for an agent-native design system.
- Unlike a coding harness (giving agents "hands"), a design harness gives agents an "eye" for design.
- Key distinction from traditional design systems: harnesses are built to be increasingly legible to agents, adding abstractions that compensate for their weak judgement and discretion.
He published a full post, a new site, and open access to the harness, calling it the future of designing with agents.
