Ruler feels like something I can definitely add to the toolbox.
Ruler
Centralise your AI coding assistant instructions. Manage rules for all agents centrally, and distribute them to their agent-specific location as needed.
Teams, individuals, and open-source projects often rely on multiple AI coding agents working in the same project. Valuable rules, encoding norms and conventions, documentation, and helpful hints for the AI, are maintained in separate locations and formats for each agent.
Ruler makes it easy to manage the rules for all agents centrally, and distributing them to their agent-specific location as needed.

Why Ruler?
Managing instructions across multiple AI coding tools becomes complex as your team grows. Different agents (GitHub Copilot, Claude, Cursor, Aider, etc.) require their own configuration files, leading to:
- Inconsistent guidance across AI tools
- Duplicated effort maintaining multiple config files
- Context drift as project requirements evolve
- Onboarding friction for new AI tools
Ruler solves this by providing a single source of truth for all your AI agent instructions, automatically distributing them to the right configuration files.
I discovered Ruler by following links to Eleanor Berger, who was part of the excellent webinar “Effective AI-Assisted Coding with Eleanor Berger and Isaac Flath”, hosted by Hugo Bowne-Anderson of Vanishing Gradients.
Eleanor and Isaac’s course Elite AI Assisted Coding looks like a winner.
