Which programming languages are supported for CLI tools?

The skill provides specific architectural patterns and recommended libraries for both Node.js (using Commander, Chalk, and Ora) and Python (using Click).

What is the 'scratch-your-own-itch' method?

It is a development philosophy where you build software to solve your own specific pain points first. This ensures the tool has immediate utility and perfect product-market fit for at least one user (yourself) before expanding to others.

Why should I build local-first applications?

Local-first apps offer superior privacy, zero latency, and offline functionality. They are ideal for personal tools because they don't require server maintenance or subscription costs.

How does this skill help avoid over-engineering?

It includes a '10-Minute Test' to validate ideas and emphasizes building 'ugly' but functional scripts first. It identifies over-engineering as an anti-pattern that kills motivation and delays actual problem-solving.

生産性とワークフロー

Builds custom, local-first tools and CLI utilities designed to solve personal productivity challenges and automate daily workflows.

This skill empowers developers to adopt a 'scratch-your-own-itch' methodology, focusing on the rapid creation of personal tools that solve immediate, real-world problems. It provides specialized guidance on building robust CLI tools using Node.js and Python, implementing local-first architectures with SQLite or JSON, and evolving simple scripts into polished products through consistent dogfooding. Whether you are looking to automate a repetitive manual task or build a private, offline-capable application, this skill provides the patterns and validation frameworks to build fast and iterate effectively.
