# Agent Skills

> Install the Fireworks training skill for your coding agent.

The `fireworks-training` skill helps coding agents configure, run, and troubleshoot training jobs using current Fireworks best practices.

## Install

### Claude Code

Install the auto-updating cookbook plugin:

```bash theme={null}
claude plugin marketplace add fw-ai/cookbook
claude plugin install fireworks-training@fw-ai-cookbook
```

### Cursor

```bash theme={null}
npx --yes skills add fw-ai/cookbook -g \
  -s fireworks-training -a cursor -y
```

### Codex

```bash theme={null}
npx --yes skills add fw-ai/cookbook -g \
  -s fireworks-training -a codex -y
```

### Other compatible agents

Install to every detected Agent Skills-compatible harness:

```bash theme={null}
npx --yes skills add fw-ai/cookbook -g \
  -s fireworks-training -a '*' -y
```

<Note>
  Skills installed with `npx skills` do not update automatically. Refresh them with `npx --yes skills update -g -y`.
</Note>

## Prerequisites

* [Fireworks CLI (`firectl`)](/docs/tools-sdks/firectl/firectl) installed. Authenticate with either `firectl signin` or `FIREWORKS_API_KEY`.
* Export `FIREWORKS_API_KEY` for Training API Python workflows.

## What it does

Ask in plain language, for example *"Fine-tune qwen3-4b on my `train.jsonl` and deploy it."* The skill configures the job, validates inputs, runs it, and helps troubleshoot failures.

Before creating cost or resources, it shows the resolved parameters and estimated cost for confirmation.

## Usage data and privacy

To improve the skill, authenticated API calls include the skill version and a random session ID. Fireworks uses this metadata with existing account and training job records for internal product analytics. Prompts and datasets are not collected, and usage data is not shared outside Fireworks.

<Note>
  The Fireworks CLI (`firectl`) may block mutating commands inside an AI-agent environment. When that happens, the skill gives you the exact command to run manually, then resumes monitoring and reporting.
</Note>

Use [managed fine-tuning](/docs/fine-tuning/managed-finetuning-intro) for standard jobs, or the [Training API](/docs/fine-tuning/training-api/introduction) for custom loops on [serverless or dedicated infrastructure](/docs/fine-tuning/training-api/choose-infrastructure).
