Matt PocockGives the agent language for the thing most architecture conversations lack: where a seam belongs, what makes a module deep rather than wide, and why a narrow interface over real work is easier for both people and agents to navigate.
In the author’s words
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.

Goes well with
pick-ui-library
Picks the library from the set Emil actually uses and trusts.
Stops your agent hand-rolling a toast or installing whatever is trending. Covers components, motion, charts, interaction, state and styling.

better-ui
Concentric radius, optical alignment, surface depth, hit areas.
Based on the Details That Make Interfaces Feel Better article. The small corrections that separate a shipped interface from a generated one.

ordinary-interfaces
180 interface rules that each carry a number and its evidence grade.
Every rule states a value, cites whether that value is spec, measured or convention, and says where it stops applying. Reads your project's own tokens before it quotes a default, so a 7px radius in a 7px system is correct rather than a finding.
