Coast Standards documentation

Last updated: 2026-09-16

Coast Standards is a set of engineering rules, and a tool that installs checks for them into your project. The checks run on every commit and push, and stop changes that break a rule. Each refusal says what was wrong and where.

Pages

• Quickstart: install it into your project in about ten minutes.
• How it works: what runs, and when.
• What gets checked: the mistakes it catches.
• Options: every setting, installer flag and file you can change.
• When a check stops you: what to do after a refusal.
• Working with AI coding agents: using Claude Code or a similar tool on the project.
• FAQ: short answers to common questions.
• The rules: the rules themselves, including the one a refusal named.
