Principal backend engineering intelligence for Java services and distributed systems. Actions: plan, design, build, implement, review, fix, optimize, refactor, debug, secure, scale backend code and architectures. Focus: correctness, reliability, performance, security, observability, scalability, operability, cost.
AI-powered comprehensive codebase documentation generator. Analyzes project structure, identifies architecture patterns, creates C4 model diagrams, and generates professional technical documentation. Use when users need to document codebases, understand software architecture, create technical specs, or generate developer guides. Supports all programming languages. Alternative to Litho/deepwiki-rs that uses Claude Code subscription without external API costs.
Expert API designer for REST, GraphQL, gRPC architectures. Activate on: API design, REST API, GraphQL schema, gRPC service, OpenAPI, Swagger, API versioning, endpoint design, rate limiting, OAuth flow. NOT for: database schema (use data-pipeline-engineer), frontend consumption (use web-design-expert), deployment (use devops-automator).
Review code for architecture: module and layer boundaries, dependency direction, single responsibility, cyclic dependencies, interface stability, and coupling. Cognitive-only atomic skill; output is a findings list.
Generate draw.io editable diagrams (.drawio, .drawio.svg) from text, images, or Excel. Orchestrates 3-agent workflow (Analysis → Manifest → SVG generation) with quality gates. Use when creating architecture diagrams, flowcharts, sequence diagrams, or converting existing images to editable format. Supports Azure/AWS cloud icons.
Expert patterns for adding multiplayer to single-player games including client-server architecture, authoritative server design, MultiplayerSynchronizer, lag compensation (client prediction, server reconciliation), input buffering, and anti-cheat measures. Use when retrofitting multiplayer, porting to online play, or designing networked gameplay. Trigger keywords: MultiplayerPeer, ENetMultiplayerPeer, SceneMultiplayer, MultiplayerSynchronizer, rpc, rpc_id, multiplayer_authority, client_prediction, server_reconciliation, lag_compensation, rollback.
Expert patterns for combat systems including hitbox/hurtbox architecture, damage calculation (DamageData class), health components, combat state machines, combo systems, ability cooldowns, and damage popups. Use for action games, RPGs, or fighting games. Trigger keywords: Hitbox, Hurtbox, DamageData, HealthComponent, combat_state, combo_system, ability_cooldown, invincibility_frames, damage_popup.
Production-grade mobile app development and architecture for iOS (Swift/SwiftUI/UIKit), Android (Kotlin/Jetpack Compose), and cross-platform (React Native, Flutter, Kotlin Multiplatform, WebView). Use for navigation, state, networking, offline storage, auth/passkeys, push, performance, testing, CI/CD, and App Store/Play release readiness.
Patterns and architectures for building AI agents and workflows with LLMs. Use when designing systems that involve tool use, multi-step reasoning, autonomous decision-making, or orchestration of LLM-driven tasks.
Logs completed epics and significant accomplishments in reverse chronological order. Use after completing major features, releases, or architecture changes to maintain a project changelog.
Automatically generate HarmonyOS design documents including architecture design documents and functional design documents based on PRD documents. It analyzes the existing code structure of OpenHarmony before generation to ensure compatibility with the current architecture. Chapter 2 of the architecture design document must be Competitor Solution Analysis, which should be placed after the Requirement Background. Applicable to user requests: (1) Generate architecture design document, (2) Generate functional design document, (3) Generate design document from PRD, (4) Create system architecture design, (5) Write functional specification, (6) Analyze OH code structure. Keywords: architecture design, functional design, design doc, competitor solution analysis, OpenHarmony code analysis, architecture design, functional design, design document generation, OH code analysis, analyze codebase, competitor analysis
Reorganize a repository from flat structure to module-based 5-layer architecture. Use for codebase restructuring, module organization, import path updates, git history preservation, artifact cleanup, directory consolidation, and hidden folder merging.
