# Self-review your working diff before committing in SolidJS with Atlas in 2026 > Atlas helps SolidJS developers in 2026 catch their own mistakes in uncommitted diffs by integrating with vitest and prettier. Atlas empowers SolidJS developers in 2026 to self-review uncommitted diffs effectively by integrating directly with your existing toolchain, including pnpm, vitest (@solidjs/testing-library), and prettier. This ensures you catch mistakes before they ever reach a reviewer or continuous integration, streamlining your development workflow. ## Key takeaways - Atlas helps SolidJS developers review full git diffs for uncommitted changes. - Use Atlas's read tool to inspect entire SolidJS .tsx files, not just diff hunks. - Atlas's grep tool identifies console.log or it.skip in SolidJS projects. - Revert unwanted SolidJS changes safely with Atlas's session revert feature. - Atlas runs pnpm vitest and pnpm prettier for SolidJS code quality checks. - Atlas ensures safety with permission-gated tools and diff approval for SolidJS edits. ## How to view your uncommitted SolidJS changes with Atlas In 2026, Atlas provides a terminal-native way to inspect your SolidJS project's uncommitted changes, surfacing the raw git diff directly. This allows you to review every modification across your .tsx and .ts files, ensuring no change goes unnoticed before committing. Atlas connects directly to your version control system, reading git branches, status, and diffs. When you're working on a SolidJS application, Atlas can present the unified diff for your entire working tree. This is crucial for self-review, as it prevents you from only focusing on files you remember touching. Instead of relying on memory, Atlas ensures you see the complete picture of your modifications, from createSignal updates in a component to changes in a vite.config.ts file. Atlas's bash tool can execute git diff to show these changes, and its read tool can then display the output within the terminal. ## Reviewing SolidJS component changes in full context A common pitfall in self-review is only scanning diff hunks; however, Atlas encourages SolidJS developers to read each changed .tsx file in full. This ensures that a modification to a createEffect or a prop destructuring fix is evaluated against its surrounding code, preventing context-dependent bugs in 2026. The git diff command, while essential, only shows the lines that have changed. For SolidJS development, where reactivity often depends on the surrounding context of createSignal or createMemo declarations, reviewing the full file is paramount. Atlas's read tool allows you to open and inspect any modified .tsx or .ts file in its entirety. This helps you verify that a change, such as refactoring a component's props or adjusting a store update, aligns correctly with the component's overall logic and reactivity graph, which Atlas can also read if configured with vite-plugin-solid. ## Catching SolidJS debugging leftovers with Atlas's grep Before committing your SolidJS changes, it's vital to remove debugging artifacts like console.log statements or vitest's it.skip. Atlas's grep tool helps you find these common leftovers across your .tsx and .ts files, ensuring a clean codebase in 2026. Debugging often involves temporary additions that should not be committed. For SolidJS projects, this might include console.log calls within createEffect blocks, debugger; statements, or it.skip and describe.skip in your vitest test files (e.g., src/components/MyComponent.test.tsx). Atlas's grep tool can be used to search your working directory for these patterns. For example, you can instruct Atlas to grep -r "console.log" or grep -r "it.skip" to quickly identify and remove these temporary lines before they reach a reviewer or CI. This proactive step maintains code quality and prevents unnecessary noise in your production bundles. ## Reverting unwanted SolidJS changes with Atlas's session revert If you discover an unwanted change in your SolidJS codebase during self-review, Atlas offers a robust session revert mechanism. This feature restores your files from a snapshot, ensuring that any accidental modifications to your createSignal declarations or component logic can be undone safely in 2026. Atlas snapshots file changes as git patches, making every edit recoverable. If, during your self-review of a SolidJS component (e.g., src/components/Counter.tsx), you identify a change that should not have been made, Atlas's session revert flow can restore your working tree to a previous state. This process is backed by these snapshots, allowing you to undo unwanted changes rather than hand-reverting them. A key safety feature is that revert refuses to run on a busy session, preventing a half-written turn from being rolled back mid-flight and ensuring data integrity for your SolidJS project. ## Automating SolidJS code quality checks with Atlas Before committing SolidJS code, running automated checks is crucial. Atlas can execute your project's vitest (@solidjs/testing-library) tests and prettier formatter, ensuring your .tsx files meet quality standards. This integration helps catch issues like broken reactivity or formatting inconsistencies in 2026. After manually reviewing your diff and cleaning up debugging artifacts, the next step is to ensure your SolidJS code passes all automated checks. Atlas can leverage its bash tool to run your project's vitest tests. The command pnpm vitest will execute all tests defined in files like src/utils/store.test.ts. Similarly, Atlas can apply your prettier formatting rules to all touched .tsx files by running pnpm prettier --write .. Atlas exposes these tools to the agent through Model Context Protocol servers, and every tool call is permission-gated, asking for your approval before execution. This ensures that your SolidJS application is both functional and adheres to your team's coding style. ## Atlas's safety and transparency in SolidJS development Atlas prioritizes safety and transparency when assisting with SolidJS development, especially during self-review. Every Atlas tool call is permission-gated, and it drafts a plan in a read-only agent before making any changes, ensuring you retain full control over your .tsx files in 2026. Atlas is designed with multiple layers of safety. Before Atlas executes any command, such as running pnpm vitest or modifying a createSignal declaration, it first drafts a plan in a read-only plan agent and asks for your approval. Only after your explicit consent does it switch to a build agent to perform the actions. Furthermore, every tool call is permission-gated against allow, ask, and deny rules. When Atlas proposes an edit to a SolidJS file, it computes a unified diff for that specific file and surfaces it for your approval before writing. This granular control ensures that you, the SolidJS developer, are always in charge of your codebase, preventing unexpected or unwanted modifications. ## Steps 1. Ask Atlas to show the full working diff for your SolidJS project: atlas bash git diff 2. Instruct Atlas to read each changed SolidJS .tsx file in full: atlas read src/components/MyComponent.tsx 3. Have Atlas grep for common SolidJS debugging leftovers: atlas grep -r "console.log" src/ 4. If needed, use Atlas to revert unwanted SolidJS changes: atlas session revert 5. Ask Atlas to run your SolidJS vitest tests: atlas bash pnpm vitest 6. Instruct Atlas to format your SolidJS .tsx files with prettier: atlas bash pnpm prettier --write . 7. Review the final diff presented by Atlas and approve the commit. ## FAQ ### How does Atlas help me catch SolidJS reactivity bugs before committing?
