everything-claude-code

Incrementally fix Python, PySpark, and pipeline errors:

Create or verify a checkpoint in your data pipeline development workflow.

Comprehensive security and quality review of uncommitted data pipeline changes:

Generate and run end-to-end pipeline tests. Creates complete pipeline test scenarios, validates data flow through components, and verifies output quality.

Manage eval-driven development workflow for data pipelines.

Analyze the current session and extract data engineering patterns worth saving as skills.

Sequential agent workflow for complex data engineering tasks.

Restate requirements, assess risks, and create step-by-step implementation plan. WAIT for user CONFIRM before touching any code.

Safely identify and remove unused components and pipelines:

Configure your preferred Python package manager (pip/poetry/uv)

Enforce test-driven development workflow for data pipelines. Define schemas first, write failing tests, then implement components. Ensure 80%+ coverage.

Analyze test coverage and generate missing tests for data pipelines:

Analyze the Atlantis framework structure and update architecture documentation:

Sync documentation from source-of-truth:

Run comprehensive verification on current pipeline code state.

Atlantis framework architecture specialist. Reviews Blackboard pattern implementation, component design, SCD patterns, metadata model structure, and monorepo organization. Ensures adherence to Atlantis principles and Azure Synapse best practices.

Data engineering code review specialist. Reviews pipeline code, transformations, SQL, and data processing logic for correctness, readability, performance, and data quality. Use after writing or modifying data pipelines.

Pandera data quality specialist. Authors schema-based validation using Pandera, integrates with Atlantis framework, validates Pydantic metadata models, and ensures data quality throughout Azure Synapse pipelines.

Dependency analysis specialist. Maps data lineage, identifies downstream consumers, and warns about breaking changes before they happen.

Atlantis framework developer. Writes composable ETL building blocks using OOP patterns, Blackboard architecture, Pydantic metadata models, and Azure Synapse. Implements SCD2/SCD1 patterns and reusable pipeline components.

Documentation specialist for data pipelines. Generates technical documentation for schemas, transformations, data quality rules, and pipeline architecture. Keeps data dictionaries and runbooks current.

Technical metadata specialist. Extracts, catalogs, and maintains technical metadata about datasets, columns, lineage, and usage patterns for data discovery and governance.

Expert planning specialist for complex features and refactoring. Use PROACTIVELY when users request feature implementation, architectural changes, or complex refactoring. Automatically activated for planning tasks.

Data pipeline refactoring specialist. Consolidates duplicate transformation logic, removes unused data quality checks, optimizes pipeline structure, and maintains clean, efficient data code.

Pydantic metadata and contract specialist for Atlantis framework. Manages TableMetadata and ProcessMetadata models, validates schema evolution, ensures type safety across pipeline components.

Data platform security specialist. Detects secrets, unsafe configs, PII exposure, and insecure patterns in data code. Validates encryption, access controls, and compliance requirements.

SQL query optimization specialist. Analyzes and optimizes SQL queries for performance, cost efficiency, and maintainability across analytical workloads.

Unit testing specialist for data engineering. Creates and maintains tests for transformations, UDFs, SQL logic, and pipeline components. Ensures data processing logic is reliable and testable.

Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.

ClickHouse database patterns, query optimization, analytics, and data engineering best practices for high-performance analytical workloads.

Universal coding standards, best practices, and patterns for TypeScript, JavaScript, React, and Node.js development.

Automatically extract reusable patterns from Claude Code sessions and save them as learned skills for future use.

A formal evaluation framework for Claude Code sessions, implementing eval-driven development (EDD) principles.

Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices.

This is an example of a project-specific skill. Use this as a template for your own projects.

Use this skill when adding authentication, handling user input, working with secrets, creating API endpoints, or implementing payment/sensitive features. Provides comprehensive security checklist and patterns.

Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.

Use this skill when writing new features, fixing bugs, or refactoring code. Enforces test-driven development with 80%+ coverage including unit, integration, and E2E tests.
