Alexanderop Claude Code Builder
alexanderop-claude-code-builder is a Claude Code plugin for the Build phase that helps you create and structure plugins, skills, subagents, hooks, and commands for Claude Code.
by alexanderop · github.com/alexanderop/claude-code-builder
Install when you are authoring or extending Claude Code with custom plugins, skills, subagents, hooks, and slash commands instead of hand-rolling boilerplate.
Add it to Claude Code
Install the plugin in Claude Code. One command, paste-ready.
/plugin install alexanderop-claude-code-builder@alexanderop/claude-code-builderBuilt to be called by your agent
Skillselion is itself an MCP server. Your agent can pull this entry and a paste-ready install config straight from the API - no copy-paste.
Retrieve this entry with skillselion.get_details("plugin:alexanderop/claude-code-builder") and the paste-ready config with skillselion.get_install_config("plugin:alexanderop/claude-code-builder").
What it does
alexanderop-claude-code-builder is a Claude Code plugin bundle aimed at people who treat the agent as the product surface. Catalog metadata and keywords point at a builder-oriented workflow for creating plugins and wiring the pieces Claude Code expects: skills, subagents, slash commands, and hooks. That makes it most relevant during Build when you are shaping how your agent behaves day to day, though you will revisit it in Operate whenever you add or refactor extensions. Solo and indie builders who outgrow copying snippets from random repos get a structured starting point instead of guessing folder layout and manifest conventions. It is not a general coding assistant skill; it is packaging and scaffolding for Claude Code itself. Pair it with your own domain skills after the skeleton exists. Expect intermediate familiarity with Claude Code plugin registration and local project structure. Community footprint is modest (34 GitHub stars at ingest) but the intent is narrow and practical for extension authors.
Highlights
- Single-plugin bundle focused on Claude Code extension authoring (builder, create, plugins).
- Covers skills, subagents, commands, and hooks called out in catalog keywords.
- Community-sourced meta-tooling for extending the agent runtime, not a one-off app integration.
- Fits solo builders shipping custom Claude Code stacks alongside skills.sh-style workflows.
- 1 plugin in the repository per catalog metadata.
Why builders use it
Hand-building Claude Code plugin folders, hooks, and agent surfaces is easy to get wrong and wastes time you could spend on product logic.
After you register the plugin, you can scaffold and iterate Claude Code extensions with a clearer, repeatable layout for skills, subagents, and commands.
