Git & Version Control

Apply Python tooling standards including uv package management, pytest testing, ruff/mypy code quality, one-line docstrings, and self-documenting code practices. Use this skill when working with Python backend code, managing dependencies, running tests, or ensuring code quality. Apply when installing packages, writing tests, formatting code, type checking, adding docstrings, organizing imports, or deciding whether to create new files vs. extending existing ones. Use for any Python development task requiring adherence to tooling standards and best practices.

Create and manage database migrations with reversible changes, proper naming conventions, and zero-downtime deployment strategies. Use this skill when creating database migration files, modifying schema, adding or removing tables/columns, managing indexes, or handling data migrations. Apply when working with migration files (e.g., db/migrate/, migrations/, alembic/, sequelize migrations), schema changes, database versioning, rollback implementations, or when you need to ensure backwards compatibility during deployments. Use for any task involving database structure changes, index creation, constraint modifications, or data transformation scripts.

Generate RFC specification documents for staff/principal engineer review based on local VCS changes. Analyzes staged/unstaged changes in jj or git, proposes architectural decisions, and produces structured RFCs with motivation, design, trade-offs, and migration sections.

Run a Cyrus release by publishing all packages to npm in the correct dependency order, updating changelogs, and creating git tags.

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. When Claude needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

MUST invoke before creating any git commit. Provides commit message format and safety rules.

Systematic peer review toolkit. Evaluate methodology, statistics, design, reproducibility, ethics, figure integrity, reporting standards, for manuscript and grant review across disciplines.

Create a new release for the Hamr launcher with version bump, git tag, and push

Run comprehensive validation and review checks including heading numbering, TODO/FIXME comments, Nextflow script conventions, orphaned files, admonition syntax, lesson structure, formatting, content accuracy, and teaching effectiveness. Use when validating, reviewing, or checking training materials quality, lesson quality, or before committing changes.

Generate Wheels MVC controllers with CRUD actions, filters, parameter verification, and proper rendering. Use when creating or modifying controllers, adding actions, implementing filters for authentication/authorization, handling form submissions, or rendering views/JSON. Ensures proper Wheels conventions and prevents common controller errors.

Generate Wheels ORM models with proper validations, associations, and methods. Use when the user wants to create or modify a Wheels model, add validations, define associations (hasMany, belongsTo, hasManyThrough), or implement custom model methods. Prevents common Wheels-specific errors like mixed argument styles and ensures proper CFML syntax.

Generate RESTful routes, nested routes, and custom routing patterns for Wheels applications. Use when defining URL structure, creating RESTful resources, or implementing custom route patterns. Ensures proper HTTP verb mapping and route constraints.

Generate TestBox BDD test specs for Wheels models, controllers, and integration tests. Use when creating tests for models (validations, associations), controllers (actions, filters), or integration workflows. Ensures comprehensive test coverage with proper setup/teardown and Wheels testing conventions.

Generate TestBox BDD test specs for Wheels models, controllers, and integration tests. Use when creating tests for models (validations, associations), controllers (actions, filters), or integration workflows. Ensures comprehensive test coverage with proper setup/teardown and Wheels testing conventions.

Generate Wheels MVC controllers with CRUD actions, filters, parameter verification, and proper rendering. Use when creating or modifying controllers, adding actions, implementing filters for authentication/authorization, handling form submissions, or rendering views/JSON. Ensures proper Wheels conventions and prevents common controller errors.

Generate documentation comments, README files, and API documentation for Wheels applications. Use when documenting code, creating project READMEs, or generating API docs.

Generate Wheels plugins with proper structure, configuration, and ForgeBox packaging. Use when creating plugins, extending Wheels functionality, or packaging reusable components. Ensures plugins follow Wheels conventions and can be easily shared via ForgeBox.

Generate documentation comments, README files, and API documentation for Wheels applications. Use when documenting code, creating project READMEs, or generating API docs.

Generate RESTful API controllers with JSON responses, proper HTTP status codes, and API authentication. Use when creating API endpoints, JSON APIs, or web services. Ensures proper REST conventions and error handling.

Generate database-agnostic Wheels migrations for creating tables, altering schemas, and managing database changes. Use when creating or modifying database schema, adding tables, columns, indexes, or foreign keys. Prevents database-specific SQL and ensures cross-database compatibility.
