# Use a Spell Checker

Using a spell checker in an IDE improves Solidity code security by catching errors in documentation, comments, and variable names that may lead to misinterpretations or vulnerabilities. While some misspellings are caught by the compiler, inconsistencies in hardcoded strings—such as those in EIP-1967 variable declarations—can still introduce risks.

Tools like [Code Spell Checker](https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker) help maintain clarity and consistency, supporting more secure and reliable smart contracts.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.optimumsec.xyz/coding/use-spell-checker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
