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.

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 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. For richer or stricter sandboxing — or to give the agent a persistent workspace — use the 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 — the agent can register a trigger and later be invoked by it.
