Scripting

Apply comprehensive bash scripting standards including main function pattern, usage documentation, argument parsing, dependency checking, and error handling. Triggers when creating/editing .sh files, bash scripts, or discussing shell scripting, deployment scripts, automation tasks, or bash conventions.

"Convert markdown files to Jupyter notebooks (.ipynb). Splits markdown by `---` delimiters into cells, extracts code blocks (```python```, ```sql```) as code cells, and handles YAML front matter removal. Use when converting documentation, tutorials, or structured markdown into interactive Jupyter notebooks."

Writing high-quality unit tests for JavaScript and TypeScript using Jest. Covers test structure (AAA pattern, USE naming), breaking dependencies (stubs, mocks, dependency injection), testing async code (promises, callbacks, timers), avoiding flaky tests, and test-driven development. Use when writing tests, debugging test failures, refactoring tests for maintainability, or questions about Jest, TDD, mocks, stubs, or test best practices.

Master advanced TypeScript patterns, generics, and type system features.

Comprehensive pre-production repository audit for preparing repos for public release. Use when the user wants to perform a "final sweep", "production check", "pre-release audit", or prepare a repository to be made public. Audits metadata files across all project types (Fabric mods, Node/npm, Go, Python, etc.) for correct username/organization, checks README links, and identifies leftover development artifacts like planning docs, test scripts, and temporary files. Interactive cleanup with user confirmation.

Generate detailed implementation plans for complex tasks. Creates comprehensive strategic plans in Markdown format with objectives, step-by-step implementation tasks using checkbox format, verification criteria, risk assessments, and alternative approaches. All plans MUST be validated using the included validation script. Use when users need thorough analysis and structured planning before implementation, when breaking down complex features into actionable steps, or when they explicitly ask for a plan, roadmap, or strategy. Strictly planning-focused with no code modifications.

Comprehensive Python library for astronomy and astrophysics. This skill should be used when working with astronomical data including celestial coordinates, physical units, FITS files, cosmological calculations, time systems, tables, world coordinate systems (WCS), and astronomical data analysis. Use when tasks involve coordinate transformations, unit conversions, FITS file manipulation, cosmological distance calculations, time scale conversions, or astronomical data processing.

How to properly create Claude Code skills - teaches global vs project-local, naming conventions, and proper file structure

Fast in-process analytical database for SQL queries on DataFrames, CSV, Parquet, JSON files, and more. Use when user wants to perform SQL analytics on data files or Python DataFrames (pandas, Polars), run complex aggregations, joins, or window functions, or query external data sources without loading into memory. Best for analytical workloads, OLAP queries, and data exploration.

OpenAI compatibility layer for Ollama. Use the official OpenAI Pythonlibrary to interact with Ollama, enabling easy migration from OpenAIand compatibility with LangChain, LlamaIndex, and other OpenAI-based tools.

This skill should be used when the user asks about "KV namespace", "R2 bucket", "D1 database", "Hyperdrive", "create binding", "list workers", "worker code", "storage binding", "database query", "object storage", "key-value store", "connection pooling", or needs to manage Cloudflare Workers storage and compute resources.

Design evidence-based powerlifting and hypertrophy training programs. Use for strength training programming, workout planning, and progressive overload systems.

Analyze text for grammar, spelling, punctuation, and style issues. Execute Python script to perform detailed analysis. Use when checking grammar or proofreading.

Write idiomatic Gleam code for the BEAM VM and JavaScript. Use when working with .gleam files, Gleam projects, or when the user mentions Gleam, BEAM, OTP actors, or type-safe functional programming.

Enforce test-first changes and debug based on failing tests.

Create or modify devops helper scripts in scripts/ or packages/*/scripts. Use for new wrappers, automation, or script style conventions.

Query up-to-date tool documentation using Context7. Use when you need current documentation for Python 3.14+, Claude Code CLI, or other configured tools.

Expert skill for writing clean, maintainable Python code using modern patterns: dataclasses, type hints, SOLID principles, and best practices.

Pulumi infrastructure as code using Go with Pulumi Cloud and ESC integration. Use when working with Pulumi Go projects, ESC environments, dynamic secrets, OIDC credentials, or infrastructure automation with Golang.

Master multiple programming languages, from Python's simplicity to Rust's safety. Learn syntax, idioms, and best practices across Python, JavaScript, Go, Java, and Rust. Covers fundamentals, OOP, functional programming, memory management, and language-specific optimization patterns.
