NebraskaCoder Claude Plugins

A personal Claude Code plugin marketplace. It hosts my reusable plugins — commands, agents, skills, and hooks — that I can install into any Claude Code session.

Installing from this marketplace

Add the marketplace once, then install any plugin from it:

/plugin marketplace add NebraskaCoder/nebraskacoder-claude-plugins
/plugin install <plugin-name>@nebraskacoder-claude-plugins

You can also browse and manage everything interactively with /plugin.

Useful management commands:

/plugin marketplace list                 # list added marketplaces
/plugin marketplace update nebraskacoder-claude-plugins
/plugin marketplace remove nebraskacoder-claude-plugins

• There is exactly one marketplace.json, at the repo root under .claude-plugin/.
• Each plugin lives in its own folder under plugins/ and has its own .claude-plugin/plugin.json.
• Plugin source paths in the catalog are relative to the repo root, e.g. "./plugins/<plugin-name>".

Adding a new plugin

Each new plugin needs a plugins/<plugin-name>/ folder with a .claude-plugin/plugin.json, plus an entry appended to the plugins array in .claude-plugin/marketplace.json.

The fastest way is the built-in create-plugin skill (in .claude/skills/): just say something like "create a new plugin" while working in this repo and it will scaffold the folder, manifest, and any components you pick, then register the plugin in the marketplace for you.

Updating a plugin

After changing an existing plugin, its version needs bumping in two places that must stay in sync — the plugin's .claude-plugin/plugin.json and its entry in .claude-plugin/marketplace.json — since Claude Code resolves plugin updates from that per-plugin version.

The built-in update-plugin skill (in .claude/skills/) handles this: say something like "bump the version", "cut a new release", or "I added a skill, sync the marketplace" while working in this repo. It surveys what changed, asks whether it's a patch, minor, or major bump, updates the version in both files, syncs descriptions/keywords, wires up any newly added component, and validates that everything lines up. (The top-level marketplace.json version is catalog metadata and is left alone on a routine plugin bump.)
