Applies type safety and error handling rules. Enforces no-any policy and type guards. Use when implementing TypeScript or reviewing types.

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

## Prerequisite Detection

Inspect `tsconfig`, runtime/framework configuration, lint/format configuration, path aliases, package scripts, and representative modules before applying project conventions. Treat a rule as project-specific only when configuration or an established pattern supports it. Label limited-pattern conclusions as inferred. When competing conventions change a public contract, runtime behavior, or error boundary, stop and name the source or user decision required.

## Type Safety in Backend Implementation

**Type Safety in Data Flow**
Input Layer (`unknown`) -> Type Guard -> Business Layer (Type Guaranteed) -> Output Layer (Serialization)

**Backend-Specific Type Scenarios**:
- **API Communication**: Receive responses as `unknown` and validate them with type guards
- **Form Input**: External input as `unknown`, type determined after validation
- **Legacy Integration**: Receive the legacy boundary as `unknown`; isolate any evidence-backed assertion in the adapter that owns the boundary

How to install

The exact contents, by fingerprint
mdr add shinpr/ai-coding-project-boilerplate/typescript-rules@sha256:14ed63860295a5fc

The line at the top of this page pins the label git:20260719.191ec13, 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.
