Make Claude Code build to your engineering principles — loaded on demand, not crammed into context.
A Claude Code plugin marketplace carrying two plugins:
| Plugin | What it does |
|---|---|
principles |
Ten portable web/engineering principles as on-demand skills — components, content, CSS, docs, forms, grid, progressive enhancement, UX, testing strategy, PR discipline. Rules are portable; values come from your own tokens.css. |
design-to-code |
Turn a design handoff (Claude Design or any self-contained HTML mocks) into production code via a measurable extract → diff → fix loop. "Looks like the design" becomes a numeric spec diff that must be empty — no done without evidence. |
Add the marketplace once:
/plugin marketplace add feedmypixel/principles
Then install either or both:
/plugin install principles@principles
/plugin install design-to-code@principles
Scope prompt: user = every session on your machine; project = committed to the repo, everyone who clones it inherits the plugin.
/plugin marketplace update principles
/plugin update principles
/plugin update design-to-code
Then a fresh session or /clear — the skill list is snapshotted at session start.
