Scripting

Tenzir Python coding standards and tooling setup. Use when editing .py files, running ruff/mypy/pytest, encountering pyproject.toml/uv.lock, or setting up a new Python project.

This skill should be used when the user asks to "get code blocks from README", "extract links from markdown", "find all headers in this doc", "pull the table from documentation", "what code examples are in this file", or when needing specific elements (code, links, headers, tables) from large Markdown files without loading the entire file.

Python code style, formatting, linting, and type hints for GMailArchiver. Use when writing Python code, fixing ruff or mypy errors, adding type hints, formatting imports, or reviewing code quality. Triggers on: style, format, lint, ruff, mypy, type hint, import order, line length, docstring.

Locate code, trace flows, and find usages in codebases. Use proactively for "where is", "how does", "find", "called", "used", or any code search question.

Create event handler hooks for Claude Code plugins that respond to tool use, sessions, and notifications. Use when creating hooks, event handlers, or automation for plugins.

Google Gemini CLI fundamentals for code analysis, review, and validation. Use when (1) executing gemini commands for code review/analysis, (2) configuring models (gemini-3-flash-preview (default)/gemini-3-pro-preview (complex only)), output formats (text/json/stream-json), or sandbox modes, (3) managing Gemini sessions with /chat save/resume, (4) integrating Gemini into automation scripts and CI/CD pipelines. Do NOT use for orchestration patterns (use gemini-claude-loop instead).

Execute complex browser automation using Playwright Python. Use for video recording, multi-page navigation, data extraction. Triggers on "browser script", "record video of website", "extract data from webpage".

R programming for data analysis, visualization, and statistical workflows. Use when working with R scripts (.R), Quarto documents (.qmd), RMarkdown (.Rmd), or R projects. Covers tidyverse workflows, ggplot2 visualizations, statistical analysis, epidemiological methods, and reproducible research practices.

Generate comprehensive GitHub ecosystem configuration including CI/CD workflows, issue templates, PR templates, CODEOWNERS, dependabot, and Copilot instructions. Language-agnostic with Python, Go, and TypeScript support. Auto-detects project language from pyproject.toml, go.mod, or package.json. Use when setting up GitHub repos, adding CI/CD pipelines, creating issue/PR templates, configuring dependabot, adding CODEOWNERS, setting up Copilot instructions, or enhancing existing projects with GitHub tooling. Works on new or existing repositories with smart merging.

Write pytest tests for Python code including unit tests, integration tests, fixtures, mocking, and parametrize. Use when writing tests for functions, classes, or complex business logic.

Standalone CLI bridge - launch external AI CLIs (gemini, codex, claude) directly without MCP server. Use when you need to delegate tasks to specialized CLI tools with their own context windows. Supports role-based prompts and file references.

Launch and control Chrome with AT-SPI2 accessibility for browser automation. Use when asked to start chrome, open browser, launch chrome, begin browser automation, or control web pages.

Automatically detect and fix Python deprecation warnings in codebases, including datetime.utcnow(), and other common deprecated patterns. Supports extensible pattern matching for future deprecations.

Systematically identify and remove unused imports, variables, and dead code from TypeScript/React projects using --noUnusedLocals and --noUnusedParameters compiler flags

Test generation expertise for Python (pytest) and TypeScript (Jest). Use when writing new tests, improving coverage, or creating test fixtures. Ensures comprehensive coverage including edge cases, error scenarios, and integration tests.

This skill enables Claude to orchestrate complex test workflows using the test-orchestrator plugin. It allows Claude to define test execution graphs with dependencies, execute tests in parallel, and intelligently select tests to run based on code changes. Use this skill when a user requests test orchestration, dependency management for tests, parallel test execution, smart test selection, or CI/CD integration for testing. Trigger terms include "orchestrate tests", "test workflow", "parallel testing", "smart test selection", "test dependencies", and "/orchestrate".

AWS Cloud Development Kit (CDK) expert for building cloud infrastructure with TypeScript/Python. Use when creating CDK stacks, defining CDK constructs, implementing infrastructure as code, or when the user mentions CDK, CloudFormation, IaC, cdk synth, cdk deploy, or wants to define AWS infrastructure programmatically. Covers CDK app structure, construct patterns, stack composition, and deployment workflows.

This skill analyzes code coverage metrics to identify untested code and generate comprehensive coverage reports. It is triggered when the user requests analysis of code coverage, identification of coverage gaps, or generation of coverage reports. The skill is best used to improve code quality by ensuring adequate test coverage and identifying areas for improvement. Use trigger terms like "analyze coverage", "code coverage report", "untested code", or the shortcut "cov".

How to write idiomatic assertions with the Bupkis assertion library for TypeScript and JavaScript

Fetch GitHub issues, PRs, repo contents, and code using the gh CLI. Use when the user shares GitHub URLs (issues, PRs, repos, source files) or asks about GitHub content. The gh CLI provides complete content that web fetching often misses due to JavaScript rendering.
