Scripting

Use this skill to query your Google NotebookLM notebooks directly from Claude Code for source-grounded, citation-backed answers from Gemini. Browser automation, library management, persistent auth. Drastically reduced hallucinations through document-only responses.

Development workflow and quality gates for the Bun + TypeScript stack. **ALWAYS use before commits** to ensure quality gates are met. Also use when starting development or when user asks about workflow process. Examples - "before commit", "quality gates", "workflow checklist", "bun commands", "pre-commit checks".

Idiomatic Python 3.14+ development. Use when writing Python code, CLI tools, scripts, or services. Emphasizes stdlib, type hints, uv/ruff toolchain, and minimal dependencies.

Python testing with pytest, coverage, fixtures, parametrization, and mocking.Covers test organization, conftest.py, markers, async testing, and TDD workflows.Use when user mentions pytest, unit tests, test coverage, fixtures, mocking,or writing Python tests.

Initialize VectorCode with automatic configuration generation. Installs git hooks,generates vectorcode.include and vectorcode.exclude patterns based on project type.Use when user mentions "initialize VectorCode", "set up VectorCode", vectorcode.include,vectorcode.exclude, or VectorCode configuration.

Best practices for TypeScript types, interfaces, assertions, and type safety. Use when writing or reviewing TypeScript code.

Prompt engineering standards and context engineering principles for AI agents based on Anthropic best practices. Covers clarity, structure, progressive discovery, and optimization for signal-to-noise ratio.

Agent Skill: Comprehensive Jira integration through lightweight Python scripts. AUTOMATICALLY TRIGGER when user mentions Jira URLs like 'https://jira.*/browse/*', 'https://*.atlassian.net/browse/*', or issue keys like 'PROJ-123'. Use when searching issues (JQL), getting/updating issue details, creating issues, transitioning status, adding comments, logging worklogs, managing sprints and boards, creating issue links, or formatting Jira wiki markup. If authentication fails, offer to configure credentials interactively. Supports both Jira Cloud and Server/Data Center with automatic authentication detection. By Netresearch.

ESLint 9.x flat config system for JavaScript and TypeScript linting.Migration from legacy .eslintrc, TypeScript integration, popular plugins (react-hooks, import).Use when configuring ESLint for complex projects, needing specialized plugins, or maintainingESLint-based workflows. For simpler needs, consider Biome.

Shell scripting expertise, command-line tools, automation, and cross-platformscripting best practices. Covers shell script development, CLI tool usage,and system automation with bash, zsh, and POSIX shell.Use when user mentions shell scripts, bash, zsh, CLI commands, pipes, command-lineautomation, or writing portable shell code.

Python code quality with ruff (linting & formatting) and mypy (type checking).Covers pyproject.toml configuration, pre-commit hooks, and type hints.Use when user mentions ruff, mypy, linting, formatting, type checking,code style, or Python code quality.

Install and configure Python and uv. Use when setting up a Python environment.

Property-based testing with fast-check (TypeScript/JavaScript) and Hypothesis (Python).Generate test cases automatically, find edge cases, and test mathematical properties.Use when user mentions property-based testing, fast-check, Hypothesis, generatingtest data, QuickCheck-style testing, or finding edge cases automatically.

Interact with a running Emacs instance via MCP. Use this skill when the user asks to interact with Emacs buffers, set up automation, or coordinate between Claude Code and Emacs. Access Elisp documentation directly via (describe-function 'fn) or (describe-variable 'var).

This skill should be used before committing code to ensure it meets Breenix quality standards. Use for running clippy checks, fixing compiler warnings, verifying no log side-effects, checking for dead code, and enforcing project coding standards from CLAUDE.md.

Execute and generate Jest tests for JavaScript/TypeScript projects with support for unit, integration, and E2E testing

JavaScript/TypeScript static analysis tool for call graphs, unused code detection (tree shaking), dependency analysis, and circular dependency detection

Automated code quality tools for scientific Python using ruff, mypy, and pre-commit hooks

Reviews Python code for type safety, async patterns, error handling, and common mistakes. Use when reviewing .py files, checking type hints, async/await usage, or exception handling.

Run TypeScript compiler type-checking (tsc --noEmit) to validate type safety and catch type errors. Works with any TypeScript project. Returns structured output with error counts, categories (type/syntax/import errors), and affected files. Used for quality gates and pre-commit validation.
