A coding CLI can help with a React feature, a TypeScript error, or a test that is missing. The hard part is making the change fit the application that already exists. Before asking an agent to write a component, show it the project conventions, existing examples, and the behavior you expect a person to see.
Ask it to learn the project before it edits
Have the agent find the package manager, framework, TypeScript configuration, component directory, test tools, and scripts that the repository already uses. Ask it to point to a nearby component with a similar job. This keeps the answer grounded in the project instead of a generic React tutorial.
Do not assume every application uses the same router, styling system, form library, or rendering model. In a framework app, the boundary between server and browser code matters. Let the existing files and instructions establish that boundary before asking for an implementation.
Describe behavior and component boundaries
Say what a user can do, what should happen after each action, and what the component must receive from its parent. Mention loading, empty, error, and success states when they apply. If a design already exists, name the current tokens and components the implementation should reuse.
For TypeScript, ask for types that reflect the real values the component receives. A prop can be optional only if the product behavior makes it optional. Avoid asking for broad type casts just to quiet an error. A type error may reveal a mistaken assumption about data, state, or an API response.
| Check | Question to answer |
|---|---|
| Types | Do props and state represent every real case? |
| Interaction | Can a person use the control with a keyboard and assistive technology? |
| States | Are loading, empty, and failure states handled where needed? |
| Project fit | Does this follow the nearby component and test pattern? |
Use the checks already in the repository
Run the project type check and the narrow test for the component or behavior. Run the production build when the change affects routing, rendering, or framework configuration. A development server that renders one page does not prove that types, tests, or the production build pass.
Read the diff for unrelated formatting, a new dependency, or changes to a shared component that were not part of the request. Ask the agent to list the exact commands it ran and to say plainly when a check could not be run.
- Find the existing component pattern and test setup.
- Describe the user action and the expected result.
- Ask for the smallest change that follows those patterns.
- Run type checks and focused tests, then inspect the full diff.
A React and TypeScript prompt you can adapt
This prompt asks the CLI to inspect first and leaves room for the actual project scripts to vary.
A prompt to adapt
In this React and TypeScript project, add [specific user behavior] to [page or component]. First inspect the TypeScript configuration, nearby components, styling approach, and relevant tests. Tell me which existing patterns you will follow. Keep the change within [scope], preserve current behavior outside it, and do not add a dependency without explaining why. After approval, implement the change, run the type check and focused tests, and summarize the files and commands.Check the official language guidance and your CLI setup
React and TypeScript have their own documentation for component props and type checking. Use those references for language questions, but use the repository itself to decide how the feature should fit. LucentraCode can work from the project terminal; check its quickstart and current model list before choosing a setup for your coding work.
