Applies GAIA's patterns and conventions for all TypeScript code. Use this skill whenever writing or reviewing TypeScript, typing exports, choosing between type and interface, using Zod schemas, defining a constant list, union type, or lookup map that other code shares, structuring function parameters, or enforcing code patterns like avoiding switch statements and enums.

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

## Types

- `import type {}` for type-only imports: `import type {ReactNode} from 'react'`

## Naming, camelCase

All identifiers use camelCase: Zod fields, form `name`/`id`/`htmlFor`, props, state, params.

**Exceptions (snake_case OK):**

- `types/database.ts`, mirrors DB column names
- Dynamic template literal names where variable part is already lowercase
- Environment variable names (`SUPABASE_URL`)

Map snake_case ↔ camelCase at API call boundaries, not in schemas or UI code.

## Naming, Descriptive and Self-Documenting

Owned by the naming-conventions skill (`.claude/skills/naming-conventions/SKILL.md`).

## Exported Functions, Explicit Return Types

All exported functions must have explicit return types.

**Exceptions:**

- Route loaders/actions (complex generics)
- React components (props typed inline on the destructured parameter, return type inferred)

```tsx
// BAD
export const formatDate = (date: Date) => format(date, 'yyyy-MM-dd');

// GOOD
export const formatDate = (date: Date): string => format(date, 'yyyy-MM-dd');
```

## General Rules

- Use `type` not `interface`
- Arrays: `string[]` not `Array<string>`
