Flags irreversible decisions before commit. Use for data models, infra, auth boundaries, API contracts, event schemas, CI/CD.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# One-way door check Some decisions are easy to reverse, you can change a UI component, rename a variable, or swap a utility function with no lasting consequences. These are **two-way doors**: walk through, and if it's wrong, walk back. Other decisions create gravity. Once traffic, users, or other code depends on them, changing course gets expensive. A database schema migration after launch. An API contract that external consumers rely on. An auth boundary that shapes your entire permission model. These are **one-way doors**. The most expensive mistakes in software aren't bugs. They're irreversible architectural decisions made too quickly. ## What gets flagged ### Data models and database schemas Files matching: `schema.prisma`, `schema.graphql`, `*.sql`, `migration*`, `models.py`, `models.ts`, `entities.py`, `entities.ts` Data models are the hardest decisions to reverse.

Relationship changes cascade through your entire application. **Questions to ask:** - Have you mapped all the relationships between entities? …

How to install
mdr add jamditis/claude-skills-journalism/one-way-door@sha256:a5425fe8a98e7014The line at the top of this page pins the label git:20261024.21f0bb2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
