team-backend

team-backend is a skill for Claude Code from tranhieutt/software_development_department. It costs 53 tokens per session (543 once invoked), scanned A, original, MIT.

A coordinated workflow for designing and reviewing a backend system with specialists in architecture, APIs, databases, and security.

In plain words
What is it for?
Use it to plan service boundaries, API contracts, database schemas and migrations, authentication, and security checks.
Why use it?
It organizes the decisions needed to take a backend feature from system design through implementation and review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

team-backend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
