# Self-review your working diff before committing in Astro with Atlas in 2026 > Atlas helps Astro developers self-review uncommitted diffs, run `vitest` tests, and format code with `prettier (prettier-plugin-astro)` using `pnpm` before committing. In 2026, Astro developers use Atlas to catch their own mistakes in uncommitted diffs before they reach a reviewer or CI, leveraging Atlas's deep integration with the Astro toolchain including `vitest`, `pnpm`, and `prettier (prettier-plugin-astro)`. Atlas provides a terminal-native environment to inspect changes, run tests, and apply formatting, ensuring high-quality code across `.astro` islands and content collections. ## Key takeaways - Atlas reads Astro git diffs end to end for comprehensive self-review. - Use Atlas `grep` to find debugging leftovers in `.astro` files and content collections. - Safely revert unwanted Astro changes with Atlas's session revert and git snapshots. - Run `vitest` tests and `prettier (prettier-plugin-astro)` formatting with Atlas `bash`. - Atlas integrates with `pnpm` for direct package management in Astro projects. ## How to review Astro diffs with Atlas before committing To effectively self-review your Astro changes in 2026, Atlas allows you to produce and read the entire working diff, not just the 1 or 2 files you remember touching. Atlas's `bash` and `read` tools provide a comprehensive view of all modifications, ensuring no change goes unnoticed. Atlas integrates directly with your Git repository, enabling you to generate and inspect the full working diff using its `bash` tool. By executing `git diff`, Atlas surfaces a unified diff for every file edit, which you can then read end to end. This is crucial for Astro projects, where changes might span across `src/pages` routes, `src/content.config.ts` schemas, or even `astro.config.mjs`. Reading each changed file in full within Atlas ensures you check the change against its surroundings, preventing context-blind mistakes that a partial review might miss. Atlas's terminal-native TUI, rendered with SolidJS, makes this process efficient and clear. ## Catch debugging leftovers in Astro components with Atlas grep Debugging leftovers like `console.log` statements or skipped `vitest` tests are common pre-commit errors. Atlas's `grep` tool, powered by AST declarations using tree-sitter, helps you find these in your Astro codebase with 100% accuracy, ensuring a clean commit. Before committing your Astro changes, it is vital to remove any temporary debugging code. Atlas's `grep` tool is specifically designed for this. Unlike simple line-based searches, Atlas indexes code by AST declarations, allowing for more precise and context-aware searches. You can use Atlas to `grep` for common debugging patterns such as `console.log`, `debugger;`, `test.skip`, or commented-out blocks within your `.astro` components, `src/pages` files, or any other part of your project. This proactive step, executed within Atlas, prevents these artifacts from reaching your team's codebase or CI, maintaining code quality and reducing future refactoring debt. ## Revert unwanted Astro changes safely with Atlas snapshots Accidental changes can happen, especially when working on complex Astro projects. Atlas provides a robust session revert mechanism, backed by git patches, that restores from a snapshot and asserts the session is not busy first, ensuring a safe rollback in under 1 second. If, during your self-review, you discover a change that should not have been made,perhaps an experimental modification to `astro.config.mjs` or an unintended edit in a content collection schema in `src/content.config.ts`,Atlas offers a safe and reliable way to undo it. Atlas's session revert feature restores your files from a previous snapshot, which are essentially git patches. A key safety measure is that Atlas refuses to run revert on a busy session, preventing a half-written turn from being rolled back mid-flight. This ensures that your work is never lost due to an ill-timed revert, providing peace of mind when making significant changes in your Astro project. ## Validate Astro code with `vitest` and `prettier` using Atlas Ensuring your Astro code passes all tests and adheres to formatting standards is a critical pre-commit step. Atlas allows you to run your `vitest` tests and apply `prettier (prettier-plugin-astro)` formatting using `pnpm` directly within its terminal environment in 2026. After reviewing your diff and cleaning up any debugging leftovers, the next crucial step is to validate your Astro code. Atlas's `bash` tool enables you to execute your project's standard commands. For testing, you can run `pnpm run test`, which will invoke `vitest` to ensure all your components and utilities function as expected. For formatting, you can run `pnpm run format`, which applies `prettier` with `prettier-plugin-astro` to maintain consistent code style across your `.astro` files, JavaScript, and TypeScript. Atlas's ability to run these commands directly means you can perform all pre-commit checks without leaving your terminal-native AI coding agent, streamlining your workflow and ensuring your Astro project remains robust and well-formatted. ## Steps 1. Use Atlas's `bash` tool to generate the full working diff by running `git diff` in your Astro project. 2. Employ Atlas's `read` tool to inspect the entire diff, file by file, paying close attention to changes in `astro.config.mjs` or `src/pages` routes. 3. Utilize Atlas's `grep` tool to search for debugging leftovers like `console.log`, `test.skip`, or commented-out blocks within your `.astro` files. 4. If an unwanted change is identified, use Atlas's session revert feature to safely restore from a snapshot, ensuring the session is not busy. 5. Execute `pnpm run test` via Atlas's `bash` tool to run all `vitest` tests for your Astro application. 6. Run `pnpm run format` using Atlas's `bash` tool to apply `prettier (prettier-plugin-astro)` formatting across your Astro codebase. 7. Review the final, clean diff within Atlas, then use Atlas's git capabilities to stage and create your commit. ## FAQ ### How does Atlas help review uncommitted Astro changes? Atlas helps by reading git diffs, providing `grep` for debugging leftovers, and allowing you to run `vitest` tests and `prettier (prettier-plugin-astro)` formatting via its `bash` tool before committing. ### Can Atlas find `console.log` statements in my Astro components? Yes, Atlas's `grep` tool can search `.astro` files and other source code for `console.log` or `test.skip` statements, leveraging AST indexing for precision. ### What Astro tools does Atlas integrate with for self-review? Atlas integrates with `vitest` for testing, `pnpm` for package management, and `prettier (prettier-plugin-astro)` for code formatting, all executable through its `bash` tool. ### How does Atlas ensure I don't accidentally revert a change mid-session? Atlas's session revert feature includes a safety check that asserts the session is not busy before restoring from a snapshot, preventing accidental rollbacks of active work. ### Can Atlas format my Astro code before committing?
