# Logfire plugin for Claude Code

A [Claude Code](https://docs.anthropic.com/en/docs/claude-code) plugin that sends OpenTelemetry traces to [Pydantic Logfire](https://logfire.pydantic.dev), giving you full observability into your Claude Code sessions.

Each session becomes a trace with child spans per LLM API call, with full token usage, cost tracking, and conversation history visible in Logfire.



## Installation

### System requirements

- [Claude Code](https://docs.anthropic.com/en/docs/claude-code) installed
- A [Logfire](https://logfire.pydantic.dev) project with a write token
- `python3` (3.7+) — pre-installed on macOS and most Linux distributions; uses stdlib only (no pip dependencies)

### Install the plugin

From within Claude Code, run:

```
/plugin marketplace add pydantic/claude-code-logfire-plugin
/plugin install logfire-session-capture@pydantic-claude-code-logfire-plugin
```

### Update the plugin

```
/plugin update logfire-session-capture@pydantic-claude-code-logfire-plugin
```

### Set your Logfire token

```bash
export LOGFIRE_TOKEN="your-logfire-write-token"
```

Add this to your shell profile (`~/.zshrc`, `~/.bashrc`, etc.) so it persists across sessions.
