# LangSmith

> Give the Sazabi agent the LangSmith CLI (langsmith) in its sandbox to inspect LLM traces, datasets, experiments, and evaluations.

[All LangSmith integration capabilities](https://docs.sazabi.com/catalogs/integrations/langsmith)

## About

This CLI connection makes the LangSmith CLI (`langsmith`) available in the Sazabi agent's sandbox. The agent can use it to inspect LLM traces, datasets, experiments, and evaluations. The tool is baked into the sandbox image; connecting it authenticates the already-installed CLI.

## Prerequisites

* A Sazabi project.
* A LangSmith API key (`LANGSMITH_API_KEY`), available from your LangSmith account settings.
* Optionally, your LangSmith workspace ID (`LANGSMITH_WORKSPACE_ID`) if you need to scope operations to a specific workspace.

## Set up in the dashboard

Configure the sandbox in the dashboard under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Step 1**

### Find LangSmith in the catalog

In [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis), find LangSmith under **Browse sandbox CLIs** and choose to connect it.

**Step 2**

### Provide credentials

Enter the required value: `LANGSMITH_API_KEY` — your LangSmith API key. Optionally, provide `LANGSMITH_WORKSPACE_ID` to scope operations to a specific workspace. Save to store them securely; Sazabi injects them into the sandbox when the agent runs.

## Set up with the CLI

You can also configure the LangSmith CLI connection with the [Sazabi CLI](https://docs.sazabi.com/reference/cli.md) (installed and authenticated — see [CLI reference](https://docs.sazabi.com/reference/cli/sandbox-clis.md)).

```bash theme={"system"}
sazabi sandbox-clis connect langsmith --env LANGSMITH_API_KEY=<your-langsmith-key>
```

To validate the credentials without saving, run the same command with `test` in place of `connect` (the test command also requires the `--env` flags).

## Verify

Ask the agent, in a thread, to run the `langsmith` CLI (a read-only or status command) and confirm it returns real output. If the command is not found, the CLI connection may not be enabled; if it runs unauthenticated or cannot connect, recheck the credentials.

## Troubleshooting

**Command not found** — Confirm the LangSmith CLI connection is enabled for the project under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Authentication or connection fails** — Recheck the credential/connection values under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).
