Experiment Guide

Overview

This chapter covers experiment management in the Experiments module and the flow for entering a lab. It fits these scenarios:

• You are signed in and ready to use experiment features.
• You want to create a new experiment or pick one from the existing list to keep working in.
• You have entered a lab but are not familiar with loading states and error prompts.

Topics: Experiment List, Create Experiment, Rename & Delete, Enter Lab, Load Failure & Retry.

Page Overview

After signing in, open the experiments page. The updated AI chat panel is fixed on the right; its top controls are shown below:

Numbers in the figure correspond to:

1. New chat: start a new AI conversation.
2. Collapse panel: reduce the right-side panel to leave more space for the experiment list.
3. Expand panel: enlarge the chat panel.
4. Close panel: close the current panel; reopen it from the AI chat entry on the left.

Experiment List

The list shows at least:

• Experiment name
• Last edited time
• Created time
• Actions column (···)

Some experiments carry an “Official” tag to distinguish built-in content from self-created ones. When the list fails to load, an error prompt is displayed directly instead of a blank page.

Create Experiment

Each account can create up to 3 experiments. After reaching the limit, the creation entry becomes unavailable; delete an existing experiment first and then create a new one.

The creation entry is the New Lab button in the top-right corner. Flow:

1. Click the New Lab button.
2. A dialog for entering the name pops up.
3. Enter the experiment name and click Create.
4. On success, the page shows a success prompt.
5. On failure, the page shows an error prompt.

Naming tips:

• Reflect the purpose directly, for example the project name, experiment topic, or task stage.
• Avoid overly generic names so you can identify items quickly in the list later.

Rename & Delete

Each experiment has an action-menu entry (··· button) on the right. Hover on the button to expand the menu:

Numbers in the figure correspond to:

1. Action menu: supports renaming and deleting the current experiment.

• Rename: Opens an input dialog; type the new name and click Save to finish.
• Delete: Deletes the current experiment; a confirmation dialog pops up before the action is executed.

A deleted experiment cannot be restored. Proceed with caution.

Enter Lab

Click an item in the experiment list to enter the lab page of that experiment. For advanced development features of the lab and AI-assisted programming, see the Lab Guide.

Numbers in the figure correspond to:

1. Top return bar: return to the experiment list; the experiment name is redacted.
2. Cloud IDE: edit code, manage files, and use the terminal.
3. AI chat panel: ask about code, errors, or task requirements.

The top of the lab page usually shows:

• Back button
• Current experiment name

If the experiment can start normally, the main area loads an embedded development environment. On the first visit you typically see a loading state before the experiment content appears.

Loading & Error Handling

The lab page has several common built-in states:

• Loading: The page shows a loading placeholder and a progress bar.
• Timeout: When the experiment address does not load successfully in time, the page indicates a timeout and provides a Retry button.
• No available address: When the current experiment has no available IDE address, the page indicates that no lab address can be provided.

Suggestions

• Know which experiment to enter: check the name and last edited time first.
• Starting a new task: use the creation entry in the top-right corner directly.
• Your main goal is the cloud IDE: the experiments page is only an entry point; continue with the Lab Guide after you get in.
