# Provider Tools

> Built-in tools — image generation, speech, transcription, web search, code execution — wired straight into the agent

Provider tools are first-class capabilities that ship with HasteKit. Toggle them on in the **Tools** tab and the agent gets a new tool — no MCP server, no OpenAPI spec, no custom code. Each tool has independent **Enabled**, **Requires Approval**, and **Deferred** switches.

## Available tools

| Tool                            | What it does                                                                                           | Configurable                                                              |
| ------------------------------- | ------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------- |
| **Image Generation**            | Generate images from text prompts.                                                                     | Provider + model (e.g. `xAI grok-imagine`, `OpenAI gpt-image-1`).         |
| **Speech Generation (TTS)**     | Synthesize speech from text.                                                                           | Provider + model + voice + language (e.g. `ElevenLabs Flash v2.5`).       |
| **Transcript Generation (STT)** | Transcribe audio to text.                                                                              | Provider + model (e.g. `ElevenLabs scribe_v2`).                           |
| **Web Search**                  | Search the web for real-time information.                                                              | None — uses the provider's native search.                                 |
| **Code Execution**              | Run code in the provider's sandboxed code interpreter.                                                 | None.                                                                     |
| **Todo Tool**                   | A built-in todo list the agent uses to plan and track multi-step tasks.                                | None.                                                                     |
| **Schedule Task Tool**          | Lets the agent schedule itself for later — recurring (cron) or one-off — and amend existing schedules. | None.                                                                     |
| **Sandbox Tool**                | Per-session Docker-backed bash sandbox with persistent workspace and file API.                         | Image, env vars. See [Sandbox Tool](/docs/gateway/agent-builder/sandbox-tool). |

## Enabling tools

1. Open your agent in the Agent Builder.
2. Click the **Tools** tab.
3. Toggle the tool on. Image / Speech / Transcript tools also let you pick the provider and model.
4. Optionally flip the **Requires Approval** switch to gate each tool call behind [human-in-the-loop](/docs/gateway/agent-builder/human-in-the-loop) confirmation.
5. Optionally flip **Deferred** to keep the tool definition out of the prompt until the agent explicitly asks for it (useful for big tool catalogs).
6. Save.

## Image / Speech / Transcription

These three are configured similarly: pick a provider, pick a model, and (for speech) a voice and language. The agent receives a single tool — e.g. `generate_image(prompt)`, `generate_speech(text)`, `transcribe(audio_url)` — and the runtime routes the call to the configured provider behind the scenes.

You can use any combination of providers for the three tools — e.g. xAI for images and ElevenLabs for speech.

## Web Search & Code Execution

These map onto the LLM provider's native capabilities. Compatibility depends on the model you pick on the Model tab.

| Tool           | OpenAI | Anthropic | Gemini |
| -------------- | ------ | --------- | ------ |
| Web Search     | ✅      | ✅         | —      |
| Code Execution | ✅      | ✅         | ✅      |

For richer or stricter sandboxing — or to give the agent a persistent workspace — use the [Sandbox Tool](/docs/gateway/agent-builder/sandbox-tool) instead of provider-level code execution.

## Todo & Schedule

Two utility tools designed for long-running, agentic workflows:

* **Todo Tool** — gives the agent `add_todo`, `update_todo`, `list_todos`. Useful for keeping a complex plan organized when the agent is doing many things in a single run.
* **Schedule Task Tool** — gives the agent `schedule_once(at, message)` and `schedule_recurring(cron, message)` so an agent can defer work, set reminders, or kick off recurring runs of itself.

Both compose naturally with [Triggers](/docs/gateway/agent-builder/triggers) — the agent can register a trigger and later be invoked by it.
