Build Agent

The Build Agent panel is where Creators interact with the Build Agent in the Module Builder. It has two tabs: Active Task and History.

Active Task Tab

The Active Task tab is the main interface for sending instructions to the Build Agent and reviewing its responses.

Chat Window

The Chat Window is the scrollable area that shows the full conversation between a Creator and the agent. It displays:

When no messages have been sent, the chat area displays two starter options: Create an Application and Explain this Workspace. Select either to send a predefined opening message.

Prompt Field

The Prompt Field is the text input at the bottom of the Active Task tab. Enter instructions and press Enter to send. Press Shift+Enter to add a new line without sending. The field accepts up to 100,000 characters.

Type @ in the prompt field to open the mention popup. The popup lists modules and applications in the current workspace. Type to filter by name, then select an item to add it to the chat context. The selected item appears as a chip in the context strip above the prompt and is included as context in the next message sent.

The context strip above the prompt displays all active context items. Items come from the currently open module, mentions, inline comments on plan steps, and components selected on the canvas. When fewer than three items are active, they display inline. When three or more are active, the strip collapses into a Chat context · N header. Select it to expand. Select the trash icon to clear all dismissible items at once.

The open module joins the context automatically. Select the × on its chip to remove it. This is useful when Creators want the Build Agent to build something new instead of working on what is on screen. It stays out until a different module is opened and returned to, or added back from the module toolbar's Add to Agent Context action, the File Explorer menu, or an @ mention.

When another task in the same module is actively running, the composer displays "Agent is working in [task name]" and input is disabled. Switch to the active task to continue, or wait for it to finish.

The Build Agent does not detect changes made to the module outside the agent during a session. If a component or test is edited manually, include a note in the next message describing what changed.

Agent Configuration

The Agent Configuration button opens a settings popover with two selectors and two toggles.

Mode controls how the agent approaches a request.

The Approvals setting controls how much the Build Agent pauses for review during execution.

Auto-test toggle: When set to ON, runs tests after the agent makes changes to verify they work correctly. Disabled when Mode is set to Ask.

Auto-fix toggle: When set to ON, automatically tries to fix issues that tests report. Requires Auto-test to be active. Disabled when Mode is set to Ask.

If a test fails because the Build Agent screenshots the module before it finishes loading, tell the agent to wait longer: "Wait at least 30 seconds before taking the screenshot." The agent respects explicit wait instructions and overrides the automatic 15-second cap.

A risk caption displays below the input area when certain mode and approval combinations are active:

• Build mode: "Agent will build without planning."

• Build + Automatic approvals: "Agent will build without planning and delete without approval."

• Plan & Build + Automatic approvals: "Agent will delete without approval."

Attachments

The Attachments button adds file context to the next message. Attached files appear as chips in the prompt field. Files can also be dragged directly onto the prompt field or pasted from the clipboard.

Files must be 10 MB or smaller total across all attachments in the conversation. Larger files are rejected at upload. The attachment badge in the toolbar turns red at 9 MB used. Additional limits apply by file type:

Supported image formats: PNG, JPEG, GIF, WEBP.

History Tab

The History tab shows all tasks and plans for the current module, grouped by time: Today, This Week, and Older. The Older group is collapsed by default. The tab label shows the total number of tasks.

Search and Filter

Task List

Each task row displays the first message of the conversation as the task title and a timestamp of the last update. An active indicator (a brand-colored dot) marks the currently open task.

Plans belonging to a task display as indented rows beneath it, each with a status badge.

Select theellipsis button on a task row to open the task actions menu.

Building a Plan

When the agent finishes creating a plan, a plan approval card displays in the Active Task tab. Select Build Plan to approve the plan and begin execution. To skip individual step confirmations, select Approve All when prompted; the agent proceeds through all remaining steps without pausing.

Select Request Changes to revise the plan. Type specific feedback in the chat input or add inline comments directly on the plan steps. The agent incorporates the feedback before presenting a revised plan for approval.

Request Changes is more effective than adding inline comments before selecting Build Plan. With inline comments only, the agent adds them to context and continues with the original plan structure. With Request Changes, the agent rewrites the plan before presenting it for approval. When a plan needs structural changes, use Request Changes instead of adding inline comments and then selecting Build Plan.

The Build Plan button at the top right of the plan detail view performs the same action as selecting Build Plan in the chat approval card.
