Impeccable Design Skills

A comprehensive, opinionated design language system that solves a real problem — LLMs generating predictable, recognizable AI slop in frontend design. The multi-provider build system (Cursor, Claude Code, Gemini, Codex) with source-of-truth authoring is genuinely well-architected.

• +Provides deeply actionable design guidance across 7 reference domains with explicit anti-patterns that directly counteract known LLM biases
• +Cross-provider build system with dedicated transformers handles real format incompatibilities gracefully
• +20 slash commands give users precise steering control rather than vague make it better interactions
• -No explicit permission declarations — the skill reads/writes files and should declare filesystem_read and filesystem_write in frontmatter
• -Reference files are substantial; could benefit from a loading strategy guide so agents don't ingest all 7 domains when only typography is relevant
