# dash0

Turns Claude sessions into OpenTelemetry traces — prompts, tool calls, token spend — and ships them to Dash0 or your own backend.

## What it does

This plugin wires a coding agent into Dash0 so you can see how it actually works. Prompts and responses, tool and MCP calls, sub-agent activity and token consumption all leave the session as OpenTelemetry traces. Follow one session turn by turn, check what each turn cost, spot where the agent stalled, and line up agent activity with the systems it touched.

Under the hood there is one shared Go pipeline plus a per-runtime surface. For Claude that means `claude-on-event.sh`, hook registration in `hooks.json`, slash commands, a configure skill and diagnostic scripts. Telemetry goes to Dash0 or to any OpenTelemetry-compatible backend; setup and configuration live in the Dash0 docs for AI SDLC Insights.

On Windows, Claude additionally needs Git for Windows, because hook commands run through Git Bash there while other runtimes use a PowerShell bootstrap. macOS, Linux and Windows are all supported, on `amd64` or `arm64`.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install dash0@claude-plugins-official
```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-official
```

## When to use it
- walk through a session turn by turn
- see what each turn cost in tokens
- find where the agent got stuck
- inspect MCP and sub-agent calls
- connect agent activity to the systems it touched

## Example prompts
- Show me the trace of my last Claude session in Dash0
- How many tokens did each turn of this session use?
- Set up telemetry export to Dash0

# Dash0 Agent Plugin

Connect your coding agent to [Dash0](https://dash0.com) for deep insight into how it's used — prompts and responses, tool calls, MCP calls, sub-agent activity, and token consumption — emitted as OpenTelemetry traces.

Trace through a session, see what each turn cost, find where the agent got stuck, and join agent activity with the systems it touches.

## Setup

Check out our documentation for setting up and configuring the Dash0 Agent Plugin: [Set Up AI SDLC Insights](https://www.dash0.com/docs/dash0/darkplane/insights/setup)

## Supported runtimes

- **Claude Code** — installation, configuration, and usage in [`.claude-plugin/README.md`](./.claude-plugin/README.md).
- **Cursor** — installation, configuration, and usage in [`.cursor-plugin/README.md`](./.cursor-plugin/README.md).
- **OpenAI Codex** — installation, configuration, and usage in [`.codex-plugin/README.md`](./.codex-plugin/README.md).
- **GitHub Copilot CLI** — installation, configuration, and usage in [`.github/plugin/README.md`](./.github/plugin/README.md).
- **OpenCode V2** — installation, configuration, and usage in [`opencode-v2/README.md`](./opencode-v2/README.md).
- **GitHub Copilot app** — installation, configuration, and usage in [`copilot-app/README.md`](./copilot-app/README.md).

All runtimes run on macOS, Linux, and Windows, on `amd64` or `arm64`. On Windows, Claude Code also needs [Git for Windows](https://gitforwindows.org/): it runs hook commands through Git Bash, where the other runtimes use a PowerShell bootstrap.

## Repository layout

This repo ships one shared Go pipeline (`cmd/`, `internal/`) and runtime-specific plugin surfaces. The rule: **`<runtime>/` holds everything shipped to that runtime**, including its `<runtime>-on-event.sh` bootstrap wrapper.

| Path | Runtime | Purpose |
|---|---|---|
| `claude/` (`claude-on-event.sh`, `hooks.json`, `commands/`, `skills/`, `tools/`), `.claude-plugin/` | Claude Code | Bootstrap wrapper, hook registration, slash commands, configure skill, diagnostic scripts, manifest |
| `cursor/` (`cursor-on-event.sh`, `hooks.json`, `skills/`), `.cursor-plugin/`, `install-cursor.sh` | Cursor | Bootstrap wrapper, hook registration, configure skill, manifest, installer |
| `codex/` (`codex-on-event.sh`, `hooks.json`), `.codex-plugin/`, `.agents/plugins/marketplace.json`, `install-codex.sh` | OpenAI Codex | Bootstrap wrapper, hook registration, manifest, self-hosted Codex marketplace, installer. Installed via marketplace (`codex plugin add`) or the installer (hooks written to `~/.codex/config.toml`). `.agents/plugins/` is Codex-only — Claude reads `.claude-plugin/`, Cursor its own dir |
| `copilot/` (`copilot-on-event.sh`, `plugin.json`, `hooks.json`, `skills/`), `.github/plugin/marketplace.json` | GitHub Copilot CLI | Self-contained plugin package (bootstrap wrapper, manifest, camelCase hooks, configure skill) + self-hosted Copilot marketplace listing it. Installed via marketplace (`copilot plugin install dash0-agent-plugin@dash0`) or the `:copilot` subpath. `.github/plugin/` is Copilot-only |
| `opencode-v2/` (`index.js`, bootstraps, `skills/`, npm metadata) | OpenCode V2 | V2 `Plugin.define` package, configure skill and persistent event-stream consumer. Installed with `opencode plugin add @dash0/agent-plugin-opencode-v2` (npm, published by the release workflow) or from a cloned path |
| `copilot-app/` (`extension.mjs`, `copilot-app-on-event.sh`, `skills/`) | GitHub Copilot app | Session extension (no manifest) that turns the app's session events into one binary call per turn, plus bootstrap wrapper and configure skill. Installed with `install_extension` pointed at this folder |

The dotted directories are fixed by each agent's plugin discovery and cannot move. Keeping every other runtime asset under `claude/`, `cursor/`, `codex/`, `copilot/`, `opencode-v2/`, and `copilot-app/` stops one marketplace from auto-discovering another runtime's components. `scripts/` is repo tooling only (release, version checks, the Docker test harness) — nothing there is shipped to a user.
