MultiTool Claude Plugins

A Claude Code plugin that onboards services to MultiTool by setting up OpenTelemetry (installing it from scratch when needed) and wiring it to the MultiTool OTLP endpoint.

What it does

The plugin ships one skill, otel-setup (invoked as /multitool:otel-setup), which Claude automatically invokes when a user mentions MultiTool in the context of tracing, monitoring, or observability. The skill:

• Detects the application's language and the current OpenTelemetry state (nothing installed, installed but pointed at another backend, or already pointed at MultiTool).
• Helps the user create a MultiTool account and mint an API key via a bundled interactive script (scripts/multitool-onboard.sh) that hides the password and never exposes the cleartext key to the model.
• Makes the code changes that point the OTLP HTTP exporter at https://api.multitool.run/api/otlp/v1/traces, set the X-API-KEY header, and populate the three mandatory resource attributes: service.name, service.version, and deployment.environment.name.

Supported languages: TypeScript/JavaScript, Python, Go, Java, Ruby, Rust, PHP, .NET.

Installation

Install the plugin from within Claude Code by adding this repo as a plugin marketplace, then installing the multitool plugin from it:

/plugin marketplace add wack/multitool-claude-plugins
/plugin install multitool@multitool-claude-plugins

The first command registers the marketplace catalog with Claude Code; the second installs the plugin to your user scope (available across all projects). If you already have the marketplace added but the plugin isn't showing up, run /plugin marketplace update multitool-claude-plugins to refresh it.

After installing, run /reload-plugins to activate the plugin without restarting Claude Code. You can manage the plugin any time by running /plugin and opening the Installed tab.

Local development

Load the plugin directly from this repo without installing it:

claude --plugin-dir .

After editing skill files, run /reload-plugins inside Claude Code to pick up changes. The skill is model-invoked, so trigger it by describing a MultiTool onboarding task rather than invoking it by name.
