| name | team-backend |
| description | Orchestrate the backend team: coordinates technical-director, backend-developer, data-engineer, and security-engineer to design, implement, and review a backend system or API end-to-end. |
| argument-hint | [backend feature or system description] |
| user-invocable | true |
| allowed-tools | Read, Glob, Grep, Write, Edit, Bash, Task, AskUserQuestion, TodoWrite |
| effort | 3 |
When this skill is invoked, orchestrate the backend team through a structured delivery pipeline.
Decision Points: At each phase, use AskUserQuestion to get user approval before proceeding.
Team Composition
- technical-director — Architecture review and approval
- backend-developer — API and service implementation
- data-engineer — Schema design and migrations
- security-engineer — Security review
Pipeline
Phase 1: Architecture Design
Delegate to technical-director:
- Review the system requirements
- Propose architecture: service boundaries, data flows, technology choices
- Identify risks and cross-cutting concerns
- Output: Architecture proposal for approval
Phase 2: Schema Design
Delegate to data-engineer:
- Design database schema based on approved architecture
- Write migration scripts (up and down)
- Define indexes and constraints
- Output: Schema design doc + migration files for review
Phase 3: API Contract Design
Delegate to backend-developer:
- Define REST/GraphQL endpoint contracts
- Specify request/response schemas and error codes
- Define authentication requirements per endpoint
- Output: API contract for frontend team to build against
Phase 4: Implementation
Delegate to backend-developer:
- Implement approved endpoints
- Apply approved schema migrations
- Write unit and integration tests
- Output: Implemented and tested backend
Phase 5: Security Review (parallel with implementation where possible)
Delegate to security-engineer:
- Review auth and authorization logic
- Check for injection vulnerabilities, insecure data exposure
- Validate input sanitization
- Output: Security review report
Phase 6: Integration
- Address security findings
- Confirm API is ready for frontend integration
- Run
/db-review and /api-design checks
Output
Summary covering: architecture decision, schema status, API contract, test coverage, and security review result.
