Install it

Read it first, then install. A skill is code that runs inside your agent.

Into

Paste this into Claude, Codex, or whichever agent you use. It reads the source first and tells you what it found before installing.

Read the SKILL.md and its companion files at https://github.com/anthropics/claude-plugins-official/tree/main/plugins/mcp-server-dev/skills/build-mcpb first.

Then tell me three things:
1. What this skill actually does
2. Whether it runs shell commands, reaches the network, writes files, or touches credentials
3. Whether it is worth adding to this project

If it looks fine, install it: npx skills add anthropics/claude-plugins-official --skill build-mcpb -a claude-code
