Braincheck

Braincheck is a lint-and-typecheck layer for Markdown knowledge bases. It exists for the unglamorous but important work of keeping front matter consistent enough that agents, scripts, and humans can trust it.

What it does

• Checks YAML front matter across a Markdown workspace
• Helps keep one schema instead of twenty almost-schemas
• Runs as a lightweight Python CLI
• Supports the practical maintenance work behind agent-readable notes
