Design and implement RESTful APIs, GraphQL endpoints, and backend API architecture following modern standards. Use this skill when creating or modifying API endpoints, route handlers, controllers, API middleware, authentication/authorization logic, or any files that define HTTP endpoints such as routes.py, api.js, controllers/, endpoints/, or API specification files (OpenAPI/Swagger). Apply this skill when implementing API versioning, rate limiting, request/response handling, API documentation, or when working with API gateway configurations. This skill is essential for building scalable, secure, and well-documented APIs that follow RESTful principles, handle errors gracefully, and provide consistent developer experiences across microservices and serverless architectures.

Follow project-wide development conventions for file organization, version control, documentation, and dependency management. Use this skill when organizing project directories and files, writing README documentation, creating commit messages, working with git branches, managing pull requests, configuring environment variables, handling secrets and API keys, managing project dependencies, setting up feature flags, maintaining changelogs, defining testing requirements, establishing code review processes, or structuring the overall project architecture. Apply this skill when setting up new projects, refactoring project structure, working with version control, managing configuration files, or ensuring the project follows consistent organizational patterns and best practices.

ABP Framework cross-cutting patterns including authorization, background jobs, distributed events, multi-tenancy, and module configuration. Use when: (1) defining permissions, (2) creating background jobs, (3) publishing/handling distributed events, (4) configuring modules.

Guide for designing Definition resources in OptAIC (the "Law"). Use when creating PipelineDef, StoreDef, AccessorDef, OpDef, MLModuleDef, or PortfolioOptimizerDef. Covers interface_spec, input/output schemas, compatibility rules, and embedded guardrail contracts.

Backend API authentication patterns with Clerk JWT middleware and route protection. Use when building REST APIs, GraphQL APIs, protecting backend routes, implementing JWT validation, setting up Express middleware, or when user mentions API authentication, backend security, JWT tokens, or protected endpoints.

This skill should be used when users need to create, validate, or modify Moqui framework services, entities, and queries. It provides comprehensive guidance for writing correct Moqui XML definitions, following framework patterns and conventions.

Generates design token documentation with visual swatches and code examples. Use when documenting token values, creating token reference guides, or building searchable design system documentation.

Empirical validation workflow for blockchain data collection pipelines before production implementation. Use when validating data sources, testing DuckDB integration, building POC collectors, or verifying complete fetch-to-storage pipelines for blockchain data.

ALWAYS use this skill for ANY Svelte component styling, design, or UI work. Svelte 5 UI design system using Tailwind CSS 4, Skeleton Labs design tokens/presets/Tailwind Components, and Bits UI headless components. Covers class composition, color systems, interactive components, forms, overlays, and all visual design.

FAIL LOUDLY pattern for selection constraints. Trigger when: (1) correlated stocks selected together, (2) min_crypto_positions ignored, (3) constraints violated silently.

Define a estrutura padrão para páginas individuais de cartas Pokémon TCG. Use quando criar novas páginas de carta, organizar layout de perícia, ou o usuário mencionar estrutura de página, layout de carta, ou template de carta.

Design and implement RESTful API endpoints following industry best practices for resource naming, HTTP methods, status codes, and versioning. Use this skill when creating or modifying API route handlers, endpoint files, controller files, or API router configuration files. Use this skill when working with REST API design, implementing HTTP endpoints in backend frameworks, defining API routes and URL patterns, setting up API versioning strategies, or configuring request/response handling in web services. Use this skill when working with files in routes/, api/, controllers/, endpoints/, or views/ directories that handle HTTP requests. Use this skill when defining OpenAPI/Swagger specifications, implementing rate limiting, or establishing API conventions for your application.

Handle token failures, API rate limits, and permission errors in GitHub Actions workflows with retry logic, validation checks, and actionable error messages.

Standardize Figma-to-code workflow using Figma MCP - always get_design_context first, then screenshot, use project tokens not hardcoded values, validate 1:1 parity

Use when creating or pricing energy consulting proposals including ASHRAE Level 1/2/3 audits, benchmarking services, commissioning, compliance pathway consulting, and performance target analysis. Provides pricing models, cost estimation, scope templates, service definitions, labor hour estimates, and proposal generation. Use when the user mentions proposal writing, pricing services, scoping work, energy audit costs, consulting rates, or needs to generate professional proposals for energy projects.

Defines the 'Composite Asset' problem and the correct data mapping patterns for Wing Commander Saga (WCS) assets. This skill should be used when understanding the relationship between POF 3D models and TBL data files, or when designing asset migration strategies that preserve gameplay functionality.

Automatically bridge long technical sessions to keep context window small and costs low. Extracts key technical decisions, resolved bugs, active tasks, and essential code snippets from conversation history into a compact markdown summary (2,000–5,000 tokens). Use when reaching a project phase milestone, when Claude warns the context window is getting full, or to start a fresh session with minimal token cost while maintaining continuity.

This skill should be used when the user asks about "game rules", "scoring", "phases", "Attack token", "Exploit token", "Ghost token", "tile placement rules", "path matching", "movement rules", "winning conditions", "turn actions", "firewall breach", "path segments", "edge nodes", or discusses Zero-Day Attack game mechanics and design.
