Server-side architecture and security — API design, error handling, validation, logging. Use when building APIs, server logic, or reviewing backend security.
Use when active Record patterns including models, associations, queries, validations, and callbacks.
Systematic implementation using APEX methodology (Analyze-Plan-Execute-eXamine) with parallel agents, self-validation, and optional adversarial review. Use when implementing features, fixing bugs, or making code changes that benefit from structured workflow.
Enterprise-grade NestJS development guidance for building modular, testable Node.js backends with TypeScript. Covers module design, dependency injection, validation, security, performance, and deployment.
Implement enterprise Single Sign-On (SSO) authentication supporting multiple identity providers with JWT RS256 tokens, backwards verification, session management, and cross-system permission mapping. Use this skill when building authentication systems that integrate with multiple enterprise SSO providers or when implementing secure token validation with session verification.
Diagnose and resolve common Guidewire InsuranceSuite errors. Use when encountering API errors, Gosu exceptions, validation failures, or integration issues in PolicyCenter, ClaimCenter, or BillingCenter. Trigger with phrases like "guidewire error", "policycenter error", "claimcenter error", "gosu exception", "api error 422".
Builds new API endpoints end-to-end. Use when adding routes, handlers/controllers, validation, service/action logic, response schemas/resources, and endpoint tests.
Validate Godot GDScript files using gdlint, gdformat, gdradon, and LSP diagnostics. Use when users want to: (1) Check code quality after making changes, (2) Validate before committing, (3) Run code metrics analysis, (4) Run export validation, (5) Get real-time LSP diagnostics. Uses command-line tools directly and MCP tools for LSP integration.
Homelab infrastructure management with Terragrunt, OpenTofu, and Terraform patterns. Use when: (1) Planning or applying infrastructure changes to dev/integration/live clusters, (2) Adding/modifying machines in inventory.hcl, (3) Creating or updating units and stacks, (4) Working with feature flags, (5) Running validation (fmt, validate, test, plan), (6) Understanding the units→stacks→modules architecture, (7) Working with HCL configuration files, (8) Bare-metal Kubernetes provisioning or Talos configuration. Triggers: "terragrunt", "terraform", "opentofu", "tofu", "infrastructure code", "IaC", "inventory.hcl", "networking.hcl", "HCL files", "add machine", "add node", "cluster provisioning", "bare metal", "talos config", "task tg:", "infrastructure plan", "infrastructure apply", "stacks", "units", "modules architecture" Always use task commands (task tg:*) instead of running terragrunt directly.
Build complete React features with proper layered architecture including UI components, business logic, API integration, and state management. Use this skill when users request implementing features like "user authentication", "shopping cart", "product listing", "file upload", or any complete functionality that requires UI + business logic + data fetching. Generates all layers - presentation (components), business logic (hooks/stores/validation), and data access (API calls/React Query). Integrates with react-component-generator for UI and provides production-ready, maintainable code following best practices.
Automated commit analysis and regression detection for AItrader. 自动化提交分析和回归检测。 Use this skill when: - Running regression checks after code changes (代码修改后运行回归检测) - Analyzing git commit history (分析 git 提交历史) - Using AI to analyze code changes (使用 AI 分析代码变更) - Checking if fix commits are still correctly applied (检查修复是否正确应用) - Before merging PRs (合并 PR 前) Keywords: commit, regression, analysis, git, fix, validation, AI, 提交, 回归, 分析
This skill provides a systematic approach for investigating and fixing bugs and issues in the codebase. Use this skill when users report bugs, unexpected behavior, test failures, or request fixes for specific issues. The skill guides through issue registration, root cause analysis, impact assessment, minimal code changes, quality validation, and E2E testing.
