Applies React/TypeScript type safety, component design, and state management rules. Use when implementing React components.

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

# TypeScript Development Rules (Frontend)

Frontend-specific React/TypeScript rules for implementation: thresholds, boundary type safety, component/state design, error handling, and project conventions.

## Prerequisite Detection

Inspect TypeScript, bundler/framework, lint/format, path-alias, React compiler, and representative component configuration before applying a project convention. Treat a convention as observed when configuration or an established repository pattern supports it; label a conclusion from limited examples as inferred. When conflicting patterns affect public behavior, compatibility, or component boundaries, stop and name the required source or decision.

## Anti-patterns and Thresholds
Signals that trigger a design change:
- Prop drilling through 3+ levels → lift to Context or state management
- Component over 300 lines → split
- Props count over 10 → split the component (3-7 is the working range)
- Optional props over 50% → introduce defaults or Context
- Props nesting deeper than 2 levels → flatten

## Type Safety at Boundaries

How to install

The exact contents, by fingerprint
mdr add shinpr/ai-coding-project-boilerplate/frontend-typescript-rules@sha256:8992691f84cdfb44

The line at the top of this page pins the label git:20260912.c0d4362, 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.
