- Added .cursor/sessions/* to .gitignore to prevent session files from being tracked. - Enhanced coding standards in SKILL.md by adding semicolons to TypeScript examples for consistency. - Improved formatting in continuous learning, detail layout, and other SKILL.md files for better readability. These changes aim to streamline development processes and maintain code quality across the project.

# TDD Command
|
|
|
|
This command invokes the **tdd-guide** agent.
|
|
|
|
## What This Command Does
|
|
|
|
1. **Scaffold types** — inputs/outputs first
|
|
2. **Write failing tests** (RED) with Vitest
|
|
3. **Implement the minimum** (GREEN)
|
|
4. **Refactor** while green
|
|
5. **Check coverage** (80%+)
|
|
|
|
## When to Use
|
|
|
|
- New validators, transformers, stores, components
|
|
- Bug fixes (reproducing test first)
|
|
- Refactors of existing logic
|
|
|
|
## Cycle
|
|
|
|
```
|
|
RED → GREEN → REFACTOR → REPEAT
|
|
```
|
|
|
|
## Example
|
|
|
|
```
|
|
User: /tdd Add validation for the full-page name field
|
|
```
|
|
|
|
```typescript
|
|
// full-page.validator.test.ts
|
|
import { createFullPageSchema } from './full-page.validator';
|
|
|
|
it('rejects an empty name', () => {
|
|
const schema = createFullPageSchema((k) => k);
|
|
expect(schema.safeParse({ code: 'ABC', name: '' }).success).toBe(false);
|
|
});
|
|
```
|
|
|
|
```bash
|
|
pnpm --filter web test
|
|
pnpm test
|
|
pnpm check:all
|
|
```
|
|
|
|
Mock `@repo/core-api` / `apiClient`, not a database. UI in `packages/ui` uses Testing Library.
