What is microsoft-style-skill?

microsoft-style-skill is a skill file for Claude Code, Anthropic's AI coding assistant, that teaches it to audit and rewrite technical documentation according to the Microsoft Writing Style Guide. You install it once, then invoke it by name in any Claude Code session whenever you have documentation to review. The skill is built for IT administrator audiences: step by step installation guides, configuration docs, troubleshooting articles, API references, and admin guides. It is not designed for marketing copy or blog posts. When invoked, it runs in one of two modes. The default rewrite mode produces an audit list of every style violation found, then outputs a corrected version of the content with a summary of changes. The detect mode produces only the audit list, which is useful if you want to review issues before deciding whether to rewrite anything. The rules come from Microsoft's published style guidance and cover several areas: correct verbs for UI interactions such as replacing click with select, updated Microsoft product terminology such as replacing Azure AD with Microsoft Entra ID, plain language replacements for wordy phrases, bold and italic formatting conventions, capitalization rules, voice and tone guidance covering second person phrasing, active voice, and present tense, plus heading and title structure. The README recommends pairing this skill with a separate avoid AI writing skill, running that pass first to strip AI generated phrasing, then running this skill afterward to align terminology and formatting. The repository has no primary programming language listed since it consists of a single SKILL.md instruction file rather than executable code.
