convention.sh is a hosted MCP server with 27 hand-tuned TypeScript conventions. Coding agents like Claude Code, Cursor, Codex, and Amp pull conventions just-in-time — so they don't thrash and you don't pay for tokens you don't need. Benchmarked on Claude Opus 4.7 to produce production-ready code 59% faster, 44% cheaper, and with 84% fewer input tokens vs baseline. Free tier available, no credit card required.

The "just-in-time" pull approach is really clever. Having the agent pull only what it needs based on what it's actually doing makes way more sense. The benchmarks are impressive - but I'm curious how they hold up across different project structures. Our codebase has a pretty opinionated setup with specific patterns for API routes, state management, and component architecture. Can you add custom conventions alongside the 27 built-in ones, or is it a fixed set?
