primitiv vs semble
primitiv: Primitiv is a design contract layer for AI agents. It scans design sources like Figma, codebase, Storybook, and token files, reconciles conflicts between them, and exposes a single machine-readable contract via MCP. Agents connect to get authoritative answers before building UI, ensuring consistency and reducing drift.; semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.
01
TL;DR
Choose primitiv if…AI agents retrieve the canonical design context before building UI components
Choose semble if…Enhancing AI agents (e.g., Claude Code, Cursor, Codex) with fast and accurate code search capabilities
