# Melodic Software Claude Code plugins
A public [Claude Code](https://code.claude.com/docs) plugin marketplace of reusable, repo-agnostic
skills, hooks, and agents. Each plugin works in any repository, and consumers customize it without
editing the plugin itself.
## Use this marketplace
```shell
/plugin marketplace add melodic-software/claude-code-plugins
/plugin install <plugin-name>@melodic-software
```
Browse and manage plugins with `/plugin`. To refresh after updates, run
`/plugin marketplace update melodic-software`.
An install from GitHub is a copy keyed on the plugin's `version`, so a change reaches it only when a
release raises that version. A marketplace added from a local clone loads each plugin in place, so
edits apply at the next session or `/reload-plugins`. See "Same-version commit drift" in
[`docs/migration-playbook.md`](https://github.com/melodic-software/claude-code-plugins/blob/HEAD/docs/migration-playbook.md#same-version-commit-drift-copied-installs).
A plugin whose catalog entry sets `defaultEnabled: false` installs disabled. Enable it with
`/plugin enable <plugin-name>`.
### Enable plugin suggestions for an organization
Some catalog entries declare `relevance` signals, so Claude Code can suggest the plugin when a
session's work matches. Suggestions appear only after an administrator allowlists the marketplace in
managed settings. This block declares the marketplace source and allowlists it:
```json
{
"extraKnownMarketplaces": {
"melodic-software": {
"source": {
"source": "github",
"repo": "melodic-software/claude-code-plugins"
}
}
},
"pluginSuggestionMarketplaces": ["melodic-software"]
}
```
The rules for this block are in
[Recommend plugins for your org](https://code.claude.com/docs/en/plugins/relevance).
## Find a plugin or skill
- [Skill cheat sheet](https://github.com/melodic-software/claude-code-plugins/blob/HEAD/docs/skill-cheat-sheet.md): from what you are doing to the skill that does it.
- [Plugin catalog](https://github.com/melodic-software/claude-code-plugins/blob/HEAD/docs/catalog.md): every plugin by category, generated from the manifests.
- [Catalog taxonomy](https://github.com/melodic-software/claude-code-plugins/blob/HEAD/docs/catalog-taxonomy.md): the categories the catalog uses.
## What this marketplace publishes
This repository is the only authoritative listing of what this marketplace publishes: the plugins in
`plugins/` on the default branch, listed machine-readably in
[`.claude-plugin/marketplace.json`](https://github.com/melodic-software/claude-code-plugins/blob/HEAD/.claude-plugin/marketplace.json).
Some third-party directory sites credit this publisher with skills that have never existed here. If
a skill credited to this marketplace is not in `plugins/` on the default branch, it is not ours.
Install from the source above, not from a mirror or directory listing. This repository does not
maintain entries on third-party lists such as
[awesome-ai-plugins](https://github.com/hashgraph-online/awesome-ai-plugins) and declines requests
to add them.
