Agents

Agents are the core of the Agent Builder. An agent combines a model, tools, and instructions into a single entity you can chat with and test.

Creating an Agent​

  1. Go to the Create page and make sure you are on the Agents tab.
  2. Click the New button and select Agent.
  3. Fill in a name and description for your agent. The name helps you identify it later, and the description explains what the agent is designed to do.
  4. Configure the model parameters (see below).
  5. Attach any tools and instructions you want the agent to use.
  6. Click Create.

Your new agent will appear in the left sidebar where you can select it to edit or test at any time.

Model Parameters​

In the Model Configuration and Output Parameters sections you can configure how the agent's underlying model behaves. There are two modes: the simpler Standard view (default) and an Advanced view.

Standard View (Default)​

The default view gives you two simple controls:

  • Verbosity — Choose between Concise, Standard, or Detailed. This controls how long the agent's responses tend to be.
  • Behavior — A stepped scale running from Consistent to Creative with seven positions: Most Consistent, Very Consistent, Consistent, Balanced (the default), Creative, Very Creative, Most Creative. Stepping toward Consistent makes the agent more focused and deterministic; stepping toward Creative makes it more varied and exploratory.

To reveal the parameters below, click Advanced Settings. Click Back to Standard Settings to return.

Advanced View​

For more control, switch to the Advanced view to set parameters directly:

  • Max Tokens — The maximum length of the agent's response. Default is 8,192. Range: 1 to 1,000,000.
  • Temperature — Controls randomness. Lower values (closer to 0) make responses more focused. Higher values (up to 2.0) make them more creative. Default is 0.7.
  • Top P — Controls diversity of word choices. Lower values make the agent more predictable. Default is 0.7. Range: 0.0 to 1.0.
  • Top K — Limits the number of word choices the model considers at each step. Default is 50. Range: 1 to 100.

Enhanced Reasoning​

In the Model Configuration section you can toggle Enhanced Reasoning ("Enable stronger reasoning capabilities") to switch the agent from the standard model (Haiku) to a more capable model (Sonnet). This is useful for agents that need to handle complex tasks, nuanced instructions, or detailed analysis.

Attaching Tools and Instructions​

When creating or editing an agent, you can attach tools and instructions using the multi-select fields on the form. Tools define what the agent can do, and instructions define how it should behave.

You can attach multiple tools and multiple instructions to a single agent. The same tool or instruction can be reused across different agents.

Managing Agents​

All your agents appear in the left sidebar of the Create page, grouped into sections such as Your Agents, Shared with You, and any organization or Third Loop agents available to you. From there you can:

  • Select an agent to view and edit its configuration.
  • Rename an agent from its "⋯" menu and selecting Rename.
  • Share an agent from its "⋯" menu to grant other users or teams Edit or View access. Agents shared with you appear under Shared with You with a badge showing your permission level; you can Leave a shared agent from its menu.
  • Delete an agent from its "⋯" menu and selecting Delete. You will be asked to confirm before deletion.
  • Search for agents using the search bar at the top of the page.

Tags​

You can add tags to your agents for organization. Tags are freeform text labels that help you categorize and find agents later.
