A guide to designing ClickHouse databases and queries for fast analysis of large datasets. ClickHouse is a column-based database built for analytical workloads rather than ordinary application transactions.
Skill Claude CodeCodex
A set of coding rules for TypeScript, JavaScript, React, and Node.js projects, covering naming, simplicity, reuse, immutability, and error handling.
Skill Claude CodeCodex
A learning system that observes coding sessions and turns repeated behaviours into reusable, confidence-scored instincts, which can later become skills, commands, or agents.
Skill Claude CodeCodex
A session-ending process that reviews a Claude Code conversation and saves reusable solutions as learned skills. It looks for patterns such as error fixes, debugging methods, workarounds, user corrections, and project-specific practices.

A collection of recommended patterns for structuring and extending Django applications, including web APIs and database-backed projects.
Skill Claude CodeCodex
A guide to securing Django web applications, including login, permissions, request protection, and safe deployment settings.
Skill Claude CodeCodex
A testing guide for Django applications using pytest-django, factory_boy, mocks, coverage reports, and Django REST Framework APIs. TDD means writing a failing test first, making it pass, and then improving the implementation.
Skill Claude CodeCodex
Verification loop for Django projects: migrations, linting, tests with coverage, security scans, and deployment readiness checks before release or PR.
Skill Claude CodeCodex
A formal evaluation framework for Claude Code sessions based on evaluation-driven development, where expected agent behavior is defined and checked like software tests. It includes code-based, model-based, and human review methods, plus pass-rate measures.
Skill Claude CodeCodex
A collection of front-end coding patterns for React and Next.js, tools for building web interfaces, and guidance on state management and performance.
Skill Claude CodeCodex
A guide to common Go programming patterns, design choices, and code conventions for writing and maintaining Go applications.
Skill Claude CodeCodex
A guide to testing Go programs with table-driven tests, subtests, benchmarks, fuzzing, and coverage checks. It also explains TDD, a workflow where you write a failing test, make it pass, then improve the code.
Skill Claude CodeCodex
A step-by-step method for finding the right code context for a coding task. It repeatedly retrieves possible files, checks their relevance, improves the search, and then searches again when needed.
Skill Claude CodeCodex
Java coding standards for Spring Boot services: naming, immutability, Optional usage, streams, exceptions, generics, and project layout.
Skill Claude CodeCodex
A collection of JPA and Hibernate patterns for Spring Boot applications, covering database entities, relationships, repositories, transactions, and query performance. JPA maps Java objects to database records, while Hibernate is a common tool that implements it.

Skill Claude CodeCodex
A project-specific guide template that records how a real application is structured, including its technologies, folders, coding patterns, tests, and deployment process. It is based on a customer-discovery platform called Zenith.
Skill Claude CodeCodex
A guide to common Python coding practices, including readable formatting, type hints, error handling, and maintainable design.
Skill Claude CodeCodex
A Python testing guide built around pytest, a Python test framework, and TDD, a method of writing a failing test before the code that makes it pass.
