How to Prompt Trae SOLO for Production-Ready Code
The first version Trae SOLO gives you is a demo. What separates a throwaway and a shipped app is how you prompt and how you iterate. This guide is about the second pass, not the first.
Direct answer: Front-load constraints in the first prompt, then iterate one concern at a time — data model, error handling, then styling — instead of asking for everything at once.
Why Does the First Prompt Decide So Much?
SOLO locks in a stack and file structure early. If your first prompt omitted that the app must run offline, you will get a fetch-based data layer, and retrofitting local persistence later means rewriting components.
State the things that are expensive to change: data storage, framework constraints, whether it needs auth, and any external API it must call.
What Belongs in the First Prompt?
| Include | Leave out |
|---|---|
| Core screens and their order | Pixel-level visual tweaks |
| Data shape and where it lives | Minor copy changes |
| External services and keys | Nice-to-have features |
| Hard constraints (offline, no backend) | Long feature wishlists |
A prompt that lists twelve features produces twelve shallow ones. Three well-specified features produce something coherent, and you can add the rest in follow-ups.
How Do You Iterate Without Starting Over?
One concern per round, in dependency order.
- Data model. “Add a tags array to each task and filter the board by tag.”
- Error handling. “Wrap storage writes in try/catch and show a toast on failure.”
- Edge cases. “Handle an empty board and a task with no due date.”
- Styling. “Make buttons full width on screens under 600px.”
Batching these into one message sounds efficient. It is not — the agent spreads attention thin and quietly drops items. One concern per request, then test in the preview before the next.
How Do You Verify What It Built?
Read the generated files, not just the preview. Previews hide problems like a form that submits twice or state that resets on navigation. Check three things per round: does the data persist across a reload, does the error path actually run, and are there dead files left from an earlier iteration.
Deleting orphaned files matters. SOLO sometimes supersedes a component without removing the old one, and stale imports accumulate.
When Should You Stop Prompting and Edit by Hand?
When you are on the third round for the same bug. If the agent has failed twice to fix a specific function, its context is probably polluted by earlier attempts, and further prompts tend to shuffle the same wrong code. Copy the file out, fix it yourself, paste it back, and continue.
That escape hatch is what keeps a SOLO project from stalling.
What Still Needs a Human?
Security review, performance on large datasets, and anything touching real user data. SOLO optimizes for a working demo, and a working demo can still ship an API key in client code. Always audit before deploying.
Quick Summary
- Put expensive-to-change constraints in the first prompt.
- Limit the initial feature list to three well-specified items.
- Iterate one concern per round: data, errors, edge cases, styling.
- Read generated files — previews hide persistence and error bugs.
- Hand-edit after two failed attempts on the same bug.
