Backend

Use when Django REST Framework for building APIs with serializers, viewsets, and authentication. Use when creating RESTful APIs.

Use when lua C API for extending Lua with native code including stack operations, calling C from Lua, calling Lua from C, creating C modules, userdata types, metatables in C, and performance optimization techniques.

Use when lINQ (Language Integrated Query) with query and method syntax, deferred execution, expression trees, and performance optimization.

Use when working with Claude Code CLI, plugins, hooks, MCP servers, skills, configuration, or any Claude Code feature - provides comprehensive official documentation for all aspects of Claude Code

This skill should be used when the user wants to add components (commands, agents, skills, hooks, or MCP servers) to the Component Reference section of the website.

Automatically manage and use nREPL servers to run/evaluate Clojure code and tests.

Generate backend tests (unit, integration, mocks). Auto-invoke when user says "write test for", "add test", "test this", or "create test".

Create REST/GraphQL API endpoint with validation, error handling, and tests. Auto-invoke when user says "add endpoint", "create API", "new route", or "add route".
