skill.md: An open standard for agent skills

Skill.md is a markdown file designed to provide coding agents with essential, up-to-date information about using a product, aiming to improve the quality of code generated by agents. It consolidates various details such as personal preferences, capabilities, limitations, and best practices that are typically scattered throughout documentation or omitted to avoid overwhelming human readers. Mintlify automatically updates the skill.md file with the latest documentation changes, ensuring agents have access to the most current context. This file can be customized by users to reflect their specific requirements and is positioned as a more effective alternative to the deprecated install.md, which had limited adoption. The skill.md serves as a cheat sheet for agents, directing them to full documentation when more context is needed, and is structured in a concise manner tailored for agent interpretation rather than human browsing.
