Can I customize the architectural rules?

Yes, the patterns are defined in a shell script hook that can be modified to include or exclude specific file patterns relevant to your project's tech stack.

Which file types are monitored by the One-Way Door skill?

It monitors critical files including SQL/Prisma schemas, Terraform/Docker configs, Authentication rules, OpenAPI/GraphQL contracts, and CI/CD pipelines.

How does this skill prevent Claude from making irreversible mistakes?

It uses a PreToolUse hook to intercept 'Write' commands. If the file being modified matches a known high-stakes pattern, the skill blocks the action and requires Claude to discuss alternatives with the user first.

Will this skill slow down my regular frontend development?

No. The skill is designed to ignore 'two-way doors' like UI components, CSS, documentation, and utility functions, allowing you to iterate quickly on reversible changes.

What is a 'one-way door' decision in software development?

A one-way door is a technical choice that is difficult or expensive to reverse once implemented and live, such as changing a database schema, an auth model, or a public API contract.

Safeguards your project by identifying irreversible architectural decisions and prompting trade-off discussions before implementation.

The One-Way Door skill is an architectural governance tool for Claude Code that distinguishes between easily reversible changes and high-stakes 'one-way door' decisions like database schemas, authentication boundaries, and infrastructure configurations. By intercepting file writes to critical system components, it prevents impulsive technical debt and forces a structured evaluation of alternatives and migration paths, ensuring that foundational choices are made with intent rather than by accident. It is particularly useful for senior developers and architects who want to maintain high standards of system design while leveraging AI-assisted coding.
