From the source SKILL.md

This is the entry skill. Choose troubleshooting, performance, or authoring review, then read only the relevant local references. The references retain the content and identities of the original MSBuild skills, with correctness fixes; they are not separate skills to activate.

What this skill does

Msbuild is a community-contributed Claude Code skill in the performance sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/msbuild/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Msbuild Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 211,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Msbuild skill?
Use Msbuild when your Claude Code task falls under the Engineering category — specifically in the performance area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Msbuild" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Msbuild skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Msbuild is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
