Use when organizing React feature folders, enforcing module boundaries or reviewing cross-feature imports. Not for local component APIs or query-cache behavior.

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

# Feature-Based Architecture Best Practices

Comprehensive architecture guide for organizing React applications by features, enabling scalable development with independent teams. Contains 42 rules across 8 categories, prioritized by impact from critical (directory structure, imports) to incremental (naming conventions).

## When to Apply

Reference these guidelines when:
- Creating new features or modules
- Organizing project directory structure
- Setting up import rules and boundaries
- Implementing data fetching patterns
- Composing components from multiple features
- Reviewing code for architecture violations

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Directory Structure | CRITICAL | `struct-` |
| 2 | Import & Dependencies | CRITICAL | `import-` |
| 3 | Module Boundaries | HIGH | `bound-` |
| 4 | Data Fetching | HIGH | `fquery-` |
| 5 | Component Organization | MEDIUM-HIGH | `fcomp-` |
| 6 | State Management | MEDIUM | `fstate-` |
| 7 | Testing Strategy | MEDIUM | `test-` |
| 8 | Naming Conventions | LOW | `name-` |

How to install

The exact contents, by fingerprint
mdr add cratis/ai/feature-arch@sha256:7af5db287ee07280

The line at the top of this page pins the label git:20261026.fc845e3, 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.
