Full-Stack Feature Development Workflow
Plan and execute full-stack features end-to-end with structured methodology
What You Can Do
You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.
Features
Structured format for requirements, acceptance criteria, and edge cases
Define endpoints, request/response schemas, error codes, and validation rules
Split frontend and backend tasks with clear contracts and dependencies
Unit tests for backends, Playwright E2E for frontends, with concrete test scenarios
Schema changes with rollback strategies and zero-downtime deployment
Field-level validation rules, error responses, and logging patterns
Feature specs, API references, test plans with cross-linked markdown
Definition of done criteria covering code, tests, logs, and documentation
Example Output
Feature Plan Output:
Feature: User Authentication Flow
API Endpoints:
- POST /auth/register → Creates user, validates email format
- POST /auth/login → Returns JWT token
- GET /auth/me → Requires Bearer token
Frontend Tasks:
- Login form component with client-side validation
- Protected route wrapper
- Token persistence in localStorage
Backend Tasks:
- User schema migration (email unique, password hashed)
- JWT token generation and verification
- Email verification workflow
Testing:
- Unit: All endpoints with valid/invalid inputs
- E2E: Register → Verify Email → Login → Navigate to Protected Page
QA Checklist:
- ✓ All endpoints validated on server
- ✓ No console errors in browser logs
- ✓ Migration tested against prod DB schema
- ✓ README with setup instructions

You can systematically diagnose database performance bottlenecks by sharing your schema, slow query logs, and execution plans with Claude. It identifies root causes—missing indexes, inefficient joins, lock contention—and provides prioritized recommendations with ready-to-implement SQL. Skip the manual log analysis and get tuning strategies tailored to your workload.
This skill provides a structured approach to analyzing process problems, identifying root causes, and recommending capacity optimizations. You'll get clear bottleneck identification, data-driven recommendations, and a framework to validate whether your solutions actually work. Perfect for diagnosing why workflows are slow and finding the leverage points that matter most.
Use Claude to systematically analyze your database queries, execution plans, and schema to identify performance bottlenecks. The skill generates actionable optimization recommendations with SQL rewrites, index strategies, and configuration tuning. You'll receive detailed before-and-after performance analysis to validate improvements and prioritize work by impact.
You'll design and implement mobile features with architectural rigor, cross-platform considerations, and edge-case handling built-in. This skill generates complete system designs, platform-specific implementation strategies, performance optimization approaches, and testing frameworks. The output is production-ready guidance spanning iOS and Android with security, offline resilience, and deployment strategies included.
You can deploy this agent to execute specific implementation tasks within a larger development plan. It operates independently with fresh context, follows test-driven development principles for every code change, and creates comprehensive handoff documentation that captures progress, decisions, and learnings for the next task executor. This ensures consistent code quality, prevents rework, and maintains continuity across distributed implementation efforts.
