What’s actually slowing this PC down?

AI coding assistants can draft repetitive React components, tests, and related code—but they work best when given project context and a narrowly defined task. A reliable workflow is to record your conventions once, reuse prompts for recurring code patterns, review every generated change, and run the checks your project actually uses.
This guide uses GitHub Copilot as a concrete example because its documentation describes repository instructions, reusable prompts, and Ask, Plan, and Agent modes. The workflow applies more broadly, but specific features and their availability vary by product and IDE.

Give the assistant your project context
A request such as “make a form” leaves important questions unanswered: which component library does the project use, how are forms validated, and where do tests belong? Put stable answers where an assistant can find them instead of repeating them in every chat.

For GitHub Copilot, repository-wide instructions can live in .github/copilot-instructions.md. GitHub recommends including relevant coding conventions and build or test information. For a React project, useful details might include the framework and language, the design system, file and naming conventions, and the commands developers use to check changes. See GitHub’s repository-instructions guidance.

Scope specialized rules to the files they concern
Path-specific instruction files can provide additional guidance for particular folders or file types—for example, React components or component tests—without making every repository instruction apply everywhere. GitHub describes both repository-wide and path-specific customization in its Copilot customization documentation. Keep instructions concise and relevant: they are context, not a substitute for a precise task.
Turn repeated work into reusable prompts
If you often ask for the same kind of component, test, or migration, make the prompt describe the project’s expected shape. GitHub documents prompt files for reusable tasks and includes a React form example that calls out design-system components, React Hook Form, TypeScript types, and validation conventions. The documentation identifies prompt files as public preview, so check whether the feature is available in your Copilot product and IDE before building a workflow around it.
A useful form-generation prompt should specify the existing libraries to use, the expected props and types, validation behavior, accessibility requirements, and tests. For a component test, specify the project’s test tools, user-visible behavior to cover, and any relevant edge cases. Reusable prompts are most valuable when they encode decisions your team has already made; they should not silently introduce new libraries or architecture.

Choose the interaction mode for the size of the task
GitHub documents Ask for coding questions and suggestions, Plan for a proposed implementation plan, and Agent for autonomous task execution. Their exact labels and experience can vary among supported products and IDEs. The appropriate mode depends on how much change you are requesting and how closely you need to inspect the steps. See GitHub’s IDE guidance.
- Ask: Use for a focused question, an explanation of existing code, or a small suggestion you intend to apply and review.
- Plan: For a change spanning multiple files or behaviors, request a plan first. Check that it fits the existing architecture and requirements before asking for implementation.
- Agent: Use task execution only when you can review the proposed edits and any commands it runs. Autonomy does not remove the need to understand the resulting change.
These are workflow recommendations, not guarantees about what a particular assistant will do. GitHub documents Copilot across surfaces for planning, building, reviewing, testing, and shipping in its overview of where Copilot can be used.
Write requests around behavior and acceptance checks
Even with repository context, make each task specific. Describe what a user should be able to do, which files or existing patterns are relevant, what must not change, and how you will judge completion. For example, a request for a form might name the existing design-system controls and validation library, describe required and invalid-input behavior, and ask for tests using the project’s established conventions.
Break a broad feature into smaller changes rather than asking for an entire feature in one underspecified prompt. For larger work, review the plan before implementation; for smaller work, request a limited draft. GitHub’s task best-practices documentation discusses repository instructions and breaking down work. (Use GitHub’s IDE guidance to evaluate responses and continue with follow-up prompts.)

A component that looks plausible in a diff can still violate React’s rules or miss a required behavior. React’s guidance says Hooks belong at the top level of React functions, and components should be rendered through JSX rather than called directly like ordinary functions. Check the generated code against the Rules of React, as well as the patterns already used in your codebase.
Best Value
Review the change for correct types, loading and error states, empty or boundary cases, and consistency with the surrounding architecture. Check accessibility deliberately: inspect labels, keyboard behavior, focus handling, and any placeholder values that need replacing. A 2025 formative study, CodeA11y: Making AI Coding Assistants Useful for Accessible Web Development, reported that 16 developers without accessibility training often failed to prompt for accessibility, omitted manual steps such as replacing placeholder attributes, or could not verify compliance. That finding describes the study participants and accessibility practices in that study—not all developers or AI coding workflows.
Finally, run the repository’s actual tests, linting, type checks, and build as appropriate. Instructions can tell an assistant which commands matter, but they do not prove the code passes them. Report a check as successful only after it has actually run and succeeded.
Treat instructions as guidance, not a guarantee
GitHub Docs warns: “Due to the non-deterministic nature of AI, Copilot may not always follow your custom instructions in exactly the same way every time they are used.” That is why reusable instructions and prompts reduce repeated setup without replacing review. If a draft misses a requirement, point to the concrete omission or failure and ask for a targeted correction, then inspect the updated diff and rerun relevant checks.
What this workflow can—and cannot—establish
Using an assistant to draft recurring React code is a practical way to reduce manual repetition, but there is no verified productivity percentage or time-saved figure for this workflow here. The actual benefit depends on the project, the task, and how much review and correction the output needs. Measure it in your own work if you need to know whether it is faster: compare equivalent tasks and include the time spent checking, fixing, and testing generated code.
For React setup, the official React documentation provides the framework’s learning and setup guidance; the React setup page displayed React v19.3 when reviewed and points readers to editor setup and TypeScript integration.
