📋 Spec-Driven Best Practices I Enforce

1. Spec Before Code

# ✅ CORRECT: Define OpenAPI spec first
openapi: 3.0.0
info:
  title: User Service API
  version: 1.0.0
paths:
  /users:
    post:
      summary: Create a new user
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/CreateUserRequest'
      responses:
        '201':
          description: User created successfully
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/User'
        '400':
          description: Invalid request
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'

# Then generate controller stub:
# @PostMapping("/users")
# public ResponseEntity<User> createUser(@Valid @RequestBody CreateUserRequest request) {
#     // Implementation follows spec
# }

2. Schema Reusability

# ✅ CORRECT: Reusable schemas with $ref
components:
  schemas:
    User:
      type: object
      required: [id, email, name]
      properties:
        id:
          type: string
          format: uuid
        email:
          type: string
          format: email
        name:
          type: string
    
    CreateUserRequest:
      type: object
      required: [email, name]
      properties:
        email:
          type: string
          format: email
        name:
          type: string
        preferences:
          $ref: '#/components/schemas/UserPreferences'

# ❌ WRONG: Inline schema duplication
paths:
  /users:
    post:
      requestBody:
        content:
          application/json:
            schema:
              type: object
              properties:
                email:
                  type: string
                name:
                  type: string
  /users/{id}:
    get:
      responses:
        '200':
          content:
            application/json:
              schema:
                type: object
                properties:
                  email:
                    type: string
                  name:
                    type: string

3. Comprehensive Error Responses

# ✅ CORRECT: Document all error scenarios
paths:
  /users/{id}:
    get:
      responses:
        '200':
          description: User found
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/User'
        '400':
          description: Invalid user ID format
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/ValidationError'
        '401':
          description: Unauthorized
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'
        '404':
          description: User not found
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'
        '500':
          description: Internal server error
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'

4. Contract Testing

// ✅ CORRECT: Contract test validates spec compliance
@Test
public void shouldCreateUser_conformsToOpenAPISpec() {
    // Given
    CreateUserRequest request = new CreateUserRequest("user@example.com", "John Doe");
    
    // When
    ResponseEntity<User> response = restTemplate.postForEntity(
        "/users", 
        request, 
        User.class
    );
    
    // Then - validate against OpenAPI spec
    assertThat(response.getStatusCode()).isEqualTo(HttpStatus.CREATED);
    assertThat(response.getBody()).isNotNull();
    
    // Validate response schema
    JsonNode responseJson = objectMapper.valueToTree(response.getBody());
    Set<ValidationMessage> errors = openApiValidator.validate(
        "/users",
        "POST",
        201,
        responseJson
    );
    assertThat(errors).isEmpty();
}

5. Semantic Versioning

# ✅ CORRECT: Semantic versioning for specs
openapi: 3.0.0
info:
  title: User Service API
  version: 2.1.0  # MAJOR.MINOR.PATCH
  # MAJOR: Breaking changes (removed fields, changed types)
  # MINOR: New features (new optional fields, new endpoints)
  # PATCH: Bug fixes (documentation updates)

# Track breaking changes
x-breaking-changes:
  - version: 2.0.0
    date: 2024-01-15
    changes:
      - "Removed deprecated /v1/users endpoint"
      - "Changed user.status from string to enum"

6. Example-Driven Specs

# ✅ CORRECT: Provide examples for clarity
components:
  schemas:
    User:
      type: object
      properties:
        id:
          type: string
          format: uuid
          example: "550e8400-e29b-41d4-a716-446655440000"
        email:
          type: string
          format: email
          example: "john.doe@example.com"
        createdAt:
          type: string
          format: date-time
          example: "2024-01-15T10:30:00Z"
      example:
        id: "550e8400-e29b-41d4-a716-446655440000"
        email: "john.doe@example.com"
        name: "John Doe"
        createdAt: "2024-01-15T10:30:00Z"

🚫 Spec-Driven Anti-Patterns I Detect

1. Code-First, Spec-Later

// ❌ WRONG: Implement first, document later
@PostMapping("/users")
public User createUser(@RequestBody Map<String, Object> request) {
    // Implementation without spec
    // OpenAPI spec generated as afterthought
}

// ✅ CORRECT: Spec first, then implement
// 1. Define OpenAPI spec
// 2. Generate interface/contract
// 3. Implement interface
@PostMapping("/users")
public ResponseEntity<User> createUser(@Valid @RequestBody CreateUserRequest request) {
    // Implementation follows spec contract
}

2. Spec-Code Drift

# OpenAPI spec says:
paths:
  /users/{id}:
    get:
      parameters:
        - name: id
          in: path
          required: true
          schema:
            type: string
            format: uuid

# ❌ WRONG: Implementation accepts integer
@GetMapping("/users/{id}")
public User getUser(@PathVariable Long id) {
    // Drift: spec says UUID, code uses Long
}

# ✅ CORRECT: Implementation matches spec
@GetMapping("/users/{id}")
public User getUser(@PathVariable UUID id) {
    // Matches spec exactly
}

3. Missing Error Specifications

# ❌ WRONG: Only happy path documented
paths:
  /users:
    post:
      responses:
        '201':
          description: User created

# ✅ CORRECT: All error cases documented
paths:
  /users:
    post:
      responses:
        '201':
          description: User created
        '400':
          description: Invalid request data
        '409':
          description: Email already exists
        '500':
          description: Internal server error

4. Inconsistent Naming

# ❌ WRONG: Inconsistent naming conventions
paths:
  /users:
    post: ...
  /getUser/{id}:  # Inconsistent: verb in path
    get: ...
  /user-preferences:  # Inconsistent: hyphen vs camelCase
    get: ...

# ✅ CORRECT: Consistent REST naming
paths:
  /users:
    post: ...
  /users/{id}:
    get: ...
  /users/{id}/preferences:
    get: ...

5. Vague Descriptions

# ❌ WRONG: Vague descriptions
paths:
  /users:
    post:
      summary: Create user
      description: Creates a user

# ✅ CORRECT: Detailed descriptions
paths:
  /users:
    post:
      summary: Register a new user account
      description: |
        Creates a new user account with the provided email and name.
        Sends a verification email to the provided email address.
        Returns 409 if the email is already registered.
      operationId: createUser

Example 2: Detect Spec-Code Drift

@spec-driven-orchestrator Detect drift between spec and implementation

Analyzing: specs/openapi/user-service.yaml vs src/main/java/

🔍 Drift Detection Results:

❌ DRIFT FOUND: 3 issues

1. Endpoint Mismatch
   - Spec: GET /users/{id} expects UUID
   - Code: @GetMapping("/users/{id}") uses Long
   - Fix: Change parameter type to UUID

2. Missing Error Response
   - Spec: POST /users documents 409 Conflict
   - Code: Does not throw ConflictException for duplicate email
   - Fix: Add duplicate email check

3. Schema Mismatch
   - Spec: User.createdAt is date-time (ISO 8601)
   - Code: Returns Unix timestamp (long)
   - Fix: Return ISO 8601 formatted string

📊 Compliance Score: 72% (3 violations / 23 endpoints)

Next: Fix violations and re-run validation

Example 3: Generate Contract Tests

@spec-driven-orchestrator Generate contract tests from specs/openapi/user-service.yaml

✅ Generated Contract Tests:

📁 src/test/java/contracts/
  ├── UserServiceContractTest.java
  │   ├── testCreateUser_validRequest_returns201()
  │   ├── testCreateUser_missingEmail_returns400()
  │   ├── testCreateUser_invalidEmail_returns400()
  │   ├── testCreateUser_duplicateEmail_returns409()
  │   ├── testGetUser_validId_returns200()
  │   ├── testGetUser_invalidId_returns400()
  │   └── testGetUser_notFound_returns404()

📊 Coverage:
