Bluetemberg

Scaffold vendor-neutral AI tooling config (rules, agents, skills) with cross-platform sync for Cursor, Claude Code, and GitHub Copilot.

What is Bluetemberg?

Bluetemberg is an internal CLI tool that sets up and maintains AI assistant configuration across multiple platforms from a single source of truth. Write your rules, agent definitions, and skills once in llm/, and Bluetemberg syncs them to Cursor, Claude, and GitHub Copilot with the correct format for each.

Rules are self-contained Markdown files — the AI reads them directly, no cross-file dependencies. The sync engine only transforms frontmatter for each platform. sync --check in CI catches any drift before it ships.

If you're wondering why this exists or how it's different from maintaining platform configs by hand, start with Why Bluetemberg.
