Claude Code

CLAUDE.md + slash skills so Claude Code ships Foundry-consistent UI.

CLAUDE.md (project root)

.claude/rules/foundry.md (optional)

Optional: project memory

Setup

Add CLAUDE.md at the repo root with Foundry agent rules.
Optionally split long guidance into .claude/rules/foundry.md and link it from CLAUDE.md.
Start sessions with: “Follow CLAUDE.md Foundry rules for all UI work.”
For repetitive tasks, add a custom slash command that injects the Quick Prompt.

Tips

Keep CLAUDE.md under ~few KB of high-signal rules — link to longer docs.
Tell Claude Code to read src/components/ui/button.tsx before inventing variants.
Use plan mode for large design-system migrations, then implement.

Paste into Claude Code when generating UI.

Works alongside project rules — the prompt steers a single task; files below keep every session consistent.
