# Api Platform DTO Resources

Api Platform DTO Resources maps Symfony entities to API Platform v4 DTOs with the Object Mapper. Use it to keep input and output contracts explicit while controlling validation and security.

**Install:**

```bash
npx degit https://github.com/dev-toolings/superpowers-symfony/tree/main/skills/api-platform-dto-resources ~/.claude/skills/api-platform-dto-resources
```

## README

# Api Platform Dto Resources (Symfony)

## Use when
- Designing or evolving API Platform contracts and operations.
- Aligning serialization, validation, and security behavior.

## Default workflow
1. Define operation-level contract and payload boundaries.
2. Implement resource/DTO/provider/processor changes with explicit mapping.
3. Apply operation-specific validation and security constraints.
4. Validate functional behavior across happy and negative paths.

## Guardrails
- Keep API contract explicit and version-aware.
- Avoid exposing internal entity fields implicitly.
- Prevent drift between docs and actual serialization.

## Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.

## Output contract
- API artifacts changed (resource/DTO/provider/processor).
- Contract/security decisions and rationale.
- Functional verification results.
