What to Do While an AI Coding Assistant Generates Code

While an AI coding assistant is generating code, clarify the task, prepare relevant files and tests, and decide how you will review the result. Treat the wait as preparation—not as proof that the code is correct—and inspect, test, and understand every change before relying on it.

Use the Waiting Time to Clarify the Task

A coding assistant can only respond to the instructions and project context it receives. Before generation finishes, check that you can describe what the code should do, what it must not do, and how you will know whether it works. This is especially useful when a request includes vague words such as “clean up,” “optimize,” or “make it secure.”

• Write down the expected input, output, and important edge cases.
• Identify constraints such as supported language versions, existing libraries, and project conventions.
• Decide what should remain unchanged. For example, a request to add a form validation rule should not silently redesign unrelated pages.
• Think of at least one normal case, one boundary case, and one invalid-input case to test.

For a function that calculates a discount, for instance, consider whether zero, negative values, missing input, and a discount above the allowed maximum have defined behavior. If you discover that the request leaves an important decision open, add that detail to a follow-up instruction when the tool allows it, or make the decision explicit during review.

Prepare the Project Context

Generation may take place in a chat window, an editor, or an environment that can inspect project files. While it runs, check whether the assistant has the context it needs: relevant source files, interface definitions, test expectations, and the project’s established patterns. Do not assume that a tool has read every file or understands the entire repository.

Useful preparation includes locating the code that calls the feature, checking how similar features are implemented, and noting the commands used to run tests or formatting checks. If the assistant works from a selected file or a small set of open files, make sure the important dependencies are available. If it can modify files directly, note the current state of the working tree or use version control so you can identify and revert unwanted changes.

Keep unrelated edits separate where practical. A clean baseline makes it easier to distinguish generated changes from your own work and to diagnose failures. Avoid starting another overlapping generation task in the same files unless you understand how the tool handles concurrent changes.

What Happens During Generation

AI coding assistants typically produce suggestions based on the prompt and the context made available to them. Depending on the tool, they may return a code snippet, propose edits, or change files. Some tools show output as it arrives; others present a result only when generation finishes. The exact process and capabilities vary, so check the tool’s own controls rather than assuming it is compiling, running tests, or checking every dependency while it works.

Generation time is not a measure of correctness. A fast answer can contain a subtle bug, and a longer answer can still misunderstand the request. Likewise, code that looks polished or uses familiar syntax may be incompatible with the project or may omit error handling. The useful question is not “How long did it take?” but “Does the result meet the requirements, fit the project, and pass appropriate checks?”

Review the Result Before Accepting It

When the assistant finishes, first compare the proposed changes with your stated goal. Read the surrounding code as well as the new lines: behavior often depends on callers, configuration, data formats, or error-handling conventions outside the generated snippet. If the tool presents a diff, review each changed file and investigate edits that are broader than expected.

1. Check scope. Confirm that only intended files and behaviors changed. Ask why any unrelated edit is necessary.
2. Check assumptions. Look for invented function names, unavailable packages, incorrect APIs, and assumptions about input or environment.
3. Check failure behavior. Consider empty, malformed, unusually large, or otherwise unexpected inputs where relevant.
4. Run project checks. Use the repository’s documented tests, type checks, linting, or build commands as appropriate.
5. Inspect failures. A passing test suite is helpful evidence, not a guarantee; a failing check should be understood rather than ignored.

For example, generated code may call a library function that does not exist in the version installed by the project. A test or build can expose that mismatch. But tests only cover what they actually exercise, so also inspect the implementation and add tests for important cases that are missing.

Common Problems and Misconceptions

A frequent misconception is that code is safe to use because it compiles. Compilation can catch some syntax and type errors, but it does not establish that the program implements the intended behavior. Similarly, a test passing does not prove that every relevant case was tested.

• Too little context: The assistant may use a plausible but incompatible pattern. Provide the relevant interface or point it to an existing example.
• Overly broad changes: A request to fix one issue may produce unnecessary refactoring. Narrow the request and review the diff.
• Missing edge cases: Ask for tests or behavior around boundary and invalid inputs, then verify them independently.
• Unfamiliar dependencies: Check package names, versions, licensing requirements, and whether a dependency is actually needed before adding it.
• Confident explanations: Treat explanations as claims to verify against the code and documentation, not as proof.

If the output is wrong, provide a specific correction: describe the observed behavior, expected behavior, and relevant error or test result. A precise follow-up is usually more useful than asking the assistant to “try again” without new information.

Privacy and Safe Use

Before sharing code or project details with any assistant, understand the tool’s data-handling settings and your organization’s rules. Avoid pasting passwords, access tokens, private keys, personal data, or confidential source material unless the tool and your authorization explicitly permit it. Removing a secret from a prompt does not necessarily remove it from a file or conversation already submitted.

Generated code deserves particular care when it handles authentication, permissions, user input, files, or network requests. Check that it does not expose secrets, skip authorization checks, or trust unvalidated input. For changes that affect production systems or sensitive data, use the same review and approval process as for other code; do not treat generation as a substitute for it.

Frequently Asked Questions

Should I keep prompting the assistant while it generates code?
Usually, wait for the current task to finish unless the tool clearly supports changing or stopping it mid-generation. Overlapping instructions can make it harder to know which request produced a change.

Can I use the code as soon as it appears?
No. Read the changes, check that they meet the requirement, and run relevant tests and project checks before relying on them.

What should I do if generation takes a long time?
Check whether the tool is still working and whether it offers a cancel or retry control. If it fails or stalls, narrow the task, verify the project context, and retry rather than assuming unfinished output is complete.

Does passing tests mean the generated code is correct?
No. It means the code passed the tests that ran. Review whether those tests cover the requested behavior and important edge cases.

What if the assistant changes files I did not ask it to change?
Inspect the diff, determine whether each change is necessary, and revert unrelated edits. Version control or a saved baseline makes this easier.

A Practical Habit

Use generation time to prepare a clear acceptance checklist, then use the result as a proposal to review—not an answer to trust automatically. A short cycle of clarify, inspect, test, and revise makes the waiting productive while keeping responsibility for the final code with the person or team accepting it.
