Scripting

NumPy library for numerical computing in Python. Use for array operations, statistical calculations, mathematical transformations, and numerical analysis of financial data.

NumPy library for numerical computing in Python. Use for array operations, linear algebra, statistical calculations, curve fitting, and mathematical transformations.

Use BioPython for biological sequence analysis, parsing sequence files, and computational molecular biology tasks.

Automate FreeCAD operations using Python scripting within FreeCAD's environment. Use for parametric modeling, macros, and batch processing in the FreeCAD application. Requires FreeCAD installation with Python console access.

Unit testing framework for Python using pytest. Use when writing test cases, validating code behavior, checking test coverage, or debugging test failures.

Translate OpenMP C/C++ parallel code to Python multiprocessing. Use when converting parallel for loops, critical sections, reductions, barriers, and shared/private variables between OpenMP and Python.

Browser automation with Puppeteer for Node.js/JavaScript environments. Use this skill for controlling Chrome/Chromium in JavaScript projects, generating PDFs, taking screenshots, or scraping JavaScript-rendered content in Node.js. NOT needed for Python projects, static HTML parsing, or processing already-fetched content.

Check and lint Rust/TypeScript code using justfile tasks (just check-crate, just clippy-crate). Use after code changes, when user mentions compilation, type checking, linting, clippy warnings, or needs to validate code quality. Runs cargo check and clippy with proper flags.

Format Rust and TypeScript code using justfile tasks (just fmt-file, just fmt-rs, just fmt-ts). Use when user edits .rs/.ts files, mentions formatting, code style, rustfmt, prettier, cleanup, or before commits/PRs. Ensures consistent code style across the codebase.

Expert knowledge of IDE/LSP tools for code navigation, diagnostics, and refactoring. Use when working with TypeScript errors, linting issues, code navigation, or IDE operations.

Migrate Python projects from setup.py/setup.cfg to pyproject.toml for use with uv. Use when upgrading legacy Python packaging, converting setup.py to modern pyproject.toml format, setting up dependency groups for development/testing, and ensuring `uv run pytest` works correctly.

Choosing and implementing dbt materializations (ephemeral, view, table, incremental, snapshots, Python models). Use this skill when deciding on materialization strategy, implementing incremental models, setting up snapshots for SCD Type 2 tracking, or creating Python models for machine learning workloads.

Use when writing or updating tests (Python, JS/Hoot, integration, or tours).

Create event-driven hooks for Claude Code automation. Configure PreToolUse, PostToolUse, Stop, and other hook events with bash scripts, environment variables, matchers, and exit codes.

Create, edit, and analyze Microsoft Word documents with tracked changes, formatting, styles, tables, headers/footers, and template-based generation. Supports .docx format using python-docx, mammoth.js, and docx libraries for Node.js and Python workflows.
