Reporails Rules

Validation rules for AI agent instruction files (CLAUDE.md, .cursorrules, copilot-instructions.md). Community-maintained.

Version: 0.5.0

Pre-1.0 — moving fast, API still evolving, feedback welcome.

Quickstart

npx @reporails/cli install

This registers the MCP server with Claude Code. Then ask Claude:

> What ails claude?

Or run directly without MCP:

npx @reporails/cli check
