Trait

Moves

  1. Preset Swap hits for 60 and takes the discipline that hits hardest. One command swaps in one of 44 complete looks, changing all 519 style values, and no component needs editing.

  2. One Design File hits for 85, 90% of the time. All 519 style values, from colors to motion, live in one markdown file, and one compile restyles every component.

    Sigil-UI@966d8805b:README.md:6-9, 21-29; packages/cli/src/commands/design.ts:103-141

  3. Agent Skills hits for 25, 2 to 4 times, 95% of the time. Setup installs ten skills, guide files that teach AI coding agents Sigil’s style values, layouts and polish rules.

  4. Doctor restores 50 health. Doctor runs seven checks on a project’s setup, from config to agent files, and marks each one pass, warn or fail.
