# Langfuse Observability Plugin for Claude Code

Trace hook-backed Claude Code sessions to [Langfuse](https://langfuse.com) — turns, generations, tool calls, and token usage — with zero code changes.

## Install

```bash
claude plugin marketplace add langfuse/Claude-Observability-Plugin
claude plugin install langfuse-observability@langfuse-observability
```

The marketplace command registers the plugin marketplace and refreshes its local cache. The install command enables the plugin for your Claude Code user scope.

Restart Claude Code after install so the hook configuration is loaded.

Then configure the plugin from within a Claude Code session. This is a Claude Code slash command, not a shell command. Run `claude` first, then type it at the session prompt:

```text
$ claude
> /plugin configure langfuse-observability@langfuse-observability
```

Alternatively, pass configuration values during install:

```bash
claude plugin install langfuse-observability@langfuse-observability \
  --config LANGFUSE_PUBLIC_KEY=pk-lf-... \
  --config LANGFUSE_SECRET_KEY=sk-lf-... \
  --config LANGFUSE_BASE_URL=https://cloud.langfuse.com
```

The plugin requires or accepts:
