Plugins

Plugins extend Claude Code with skills, agents, hooks, and MCP or LSP integrations. This page tracks the plugins enabled in my settings.json, checked on 2026-10-09. Entries in enabledPlugins describe configuration; they do not confirm that a plugin is installed on a particular machine.

Enabled plugins

Section titled “Enabled plugins”
  • Nette — nette@nette: application-development skills for the Nette PHP ecosystem, including architecture, dependency injection, database access, forms, Latte, and Tracy.
  • Frontend Design — frontend-design@claude-plugins-official: guidance for creating distinctive frontend interfaces with polished design.
  • Agent Skills — agent-skills@addy-agent-skills: engineering workflows across planning, implementation, testing, review, and shipping. See Skill Collections for more detail.
  • Swift LSP — swift-lsp@claude-plugins-official: Swift code intelligence through SourceKit-LSP. Its server configuration runs the sourcekit-lsp executable.
  • CLAUDE.md Management — claude-md-management@claude-plugins-official: audit and improve CLAUDE.md files, capture session learnings, and keep project instructions current.

Marketplaces

Section titled “Marketplaces”

extraKnownMarketplaces registers plugin catalogs separately from enabledPlugins.

Marketplace GitHub source in settings Explicit auto-update setting
nette nette/claude-code true
impeccable pbakaus/impeccable true
addy-agent-skills addyosmani/agent-skills Not set

The three @claude-plugins-official plugins come from Anthropic’s official marketplace, which is not listed in extraKnownMarketplaces.

Impeccable remains a registered marketplace, but impeccable@impeccable is absent from enabledPlugins. Registration alone does not enable its plugin.

The configured nette/claude-code URL now redirects to nette/agent-plugins; the Nette project documents the new name for installation.

Installation

Section titled “Installation”

Add the custom marketplaces, then install the enabled plugins in Claude Code:

/plugin marketplace add nette/agent-plugins
/plugin marketplace add addyosmani/agent-skills
/plugin install nette@nette
/plugin install frontend-design@claude-plugins-official
/plugin install agent-skills@addy-agent-skills
/plugin install swift-lsp@claude-plugins-official
/plugin install claude-md-management@claude-plugins-official

Use /plugin to inspect installed plugins and their scope. Adding a marketplace makes its plugins discoverable; installing a plugin is a separate step.
