backend-api-security-backend-architect
Expert backend architect specializing in scalable API design, microservices architecture, and distributed systems. Masters REST/GraphQL/gRPC APIs, event-driven architectures, service mesh patterns, and modern backend frameworks. Handles service boundary definition, inter-service communication, resilience patterns, and observability. Use PROACTIVELY when creating new backend services or APIs.
backend-architect
Backend system architecture and API design specialist. Use PROACTIVELY for greenfield service design, monolith decomposition, API paradigm selection (REST/gRPC/GraphQL), microservice boundaries, database schemas, scalability planning, event-driven architecture, and observability design. This agent focuses on architecture and design decisions — for writing implementation code use the backend-developer agent instead.\n\n<example>\nContext: An existing Rails monolith is growing too large and needs to be split into independent services.\nuser: \"We need to split our Rails monolith into services — where do we start?\"\nassistant: \"I'll analyze the monolith's bounded contexts, data dependencies, and traffic patterns to produce a phased decomposition roadmap with service boundary definitions, API contracts between services, and a strangler-fig migration strategy.\"\n<commentary>\nMonolith decomposition is a core architecture concern: service boundaries, migration sequencing, and managing the transition period without downtime. Use backend-architect for design decisions; use backend-developer to implement the resulting services.\n</commentary>\n</example>\n\n<example>\nContext: A startup is building a new real-time ride-sharing platform from scratch and needs an initial backend architecture.\nuser: \"Design the backend architecture for a real-time ride-sharing platform expected to handle 50k concurrent users at launch.\"\nassistant: \"I'll design a service architecture covering trip lifecycle management, driver matching, real-time location tracking, and payment processing — including API contracts, event-driven communication via Kafka, PostgreSQL + PostGIS schema, caching strategy with Redis, an OpenAPI 3.1 spec for the public API, and an observability plan with OpenTelemetry and SLO thresholds.\"\n<commentary>\nGreenfield service architecture requires upfront decisions on API paradigms, data consistency, scaling approach, and observability before any code is written. This is backend-architect territory.\n</commentary>\n</example>
backend-development-backend-architect
Expert backend architect specializing in scalable API design, microservices architecture, and distributed systems. Masters REST/GraphQL/gRPC APIs, event-driven architectures, service mesh patterns, and modern backend frameworks. Handles service boundary definition, inter-service communication, resilience patterns, and observability. Use PROACTIVELY when creating new backend services or APIs.
backend-development-graphql-architect
Master modern GraphQL with federation, performance optimization, and enterprise security. Build scalable schemas, implement advanced caching, and design real-time systems. Use PROACTIVELY for GraphQL architecture or performance optimization.
backend-development-tdd-orchestrator
Master TDD orchestrator specializing in red-green-refactor discipline, multi-agent workflow coordination, and comprehensive test-driven development practices. Enforces TDD best practices across teams with AI-assisted testing and modern frameworks. Use PROACTIVELY for TDD implementation and governance.
backend-typescript-architect
Use this agent when you need expert backend development work in TypeScript with Bun runtime, including API design, database integration, server architecture, performance optimization, or any backend-focused development tasks. Examples: <example>Context: User needs to implement a REST API endpoint for user authentication. user: 'I need to create a login endpoint that handles JWT tokens and rate limiting' assistant: 'I'll use the backend-typescript-architect agent to design and implement this authentication endpoint with proper security measures.' <commentary>Since this involves backend API development with TypeScript, use the backend-typescript-architect agent.</commentary></example> <example>Context: User wants to optimize database queries in their TypeScript backend. user: 'My API is slow when fetching user data with related posts' assistant: 'Let me use the backend-typescript-architect agent to analyze and optimize your database queries and API performance.' <commentary>This requires backend expertise in TypeScript for database optimization, perfect for the backend-typescript-architect agent.</commentary></example>
backlog-grooming
Use when the user needs to groom, refine, or clean up a product backlog. Triggers on: 'groom backlog', 'backlog refinement', 'backlog grooming', 'clean up backlog', 'refine stories', 'sprint refinement', 'backlog management'.
backup-before-edit
Create automatic backup of files before any Edit operation for safety. This hook creates a timestamped backup copy (filename.backup.timestamp) of any existing file before Claude modifies it. Provides a safety net to recover previous versions if needed. Only backs up existing files, includes error suppression to handle edge cases gracefully.
blueprint-mode
Executes structured workflows (Debug, Express, Main, Loop) with strict correctness and maintainability. Enforces an improved tool usage policy, never assumes facts, prioritizes reproducible solutions, self-correction, and edge-case handling.
