SOLO Coder
SOLO Coder is an agent designed for complex project development. It enables you to efficiently complete the full development workflow, from requirements iteration to architecture refactoring. Through intelligent task planning and precise execution mechanisms, SOLO Coder can automatically advance development after the plan is confirmed. At the same time, you can also autonomously orchestrate multiple agents to form your own AI team, achieve multi-role collaborative workflow, and accelerate project implementation.
Billing
- During the free trial period, refer to the billing rules in TRAE for details.
- After the free trial ends, the official billing rule will be launched — stay tuned.
Important notes
SOLO Coder uses Max mode by default and the mode cannot be changed. In Max mode, billing is based on the number of tokens used, which may result in higher usage costs. For more information, refer to "Max Mode".
Prerequisites
TRAE has been switched to SOLO mode using the mode switch toggle in the upper-left corner of the interface.
Enable SOLO Coder
After entering SOLO mode, directly select the SOLO Coder card on the right side of the page, or click `@ > SOLO Coder` in the chat box.
Edit SOLO Coder
You can independently select custom agents that can be called by SOLO Coder, and configure MCP Server and built-in tools for it.
Hover the mouse over the configuration icon, then click the Edit Tools button on the panel to go to SOLO Coder's configuration panel.
Related features
Call custom agents
SOLO Coder supports calling custom agents to accomplish modular tasks.
SOLO Coder has the "Search" agent built in by default to retrieve and view files, enabling SOLO Coder to call other agents more accurately to complete tasks.
After configuring other callable agents for SOLO Coder, as the primary agent, it can automatically call the corresponding agents to split and isolate tasks when executing and handling complex, context-heavy projects. This enables different agents to focus on handling their respective tasks within independent contexts, thereby improving overall execution efficiency and the quality of results.
In addition, you can also explicitly specify the agent to be called in your prompt, and SOLO Coder will call the agent at the appropriate time based on the context.
To configure agents that can be called by SOLO Coder, refer to the agent parameter configuration part in “Create a custom agent”.
Plan mode
The Plan mode is suitable for complex, long tasks, and the switch is located in the top-right corner of the chat box.
After this mode is enabled, when SOLO Coder receives a requirement, it will analyze the requirement and plan tasks. Once the user confirms the plan, it will execute them one by one.
To modify the generated plan if it does not meet your expectations, use one of the following two methods:
- Edit the content manually. After editing is complete, click the Execute button.
- Send a modification request to SOLO Coder and have it automatically adjust the content according to instructions.
> Note
> Once a task begins to be executed, SOLO Coder will exit Plan mode.
