## How Atlas Initiates a Tauri Pull Request Review

Atlas begins a Tauri pull request review by first fetching the specific branch and generating a comprehensive diff using its `bash` tool, ensuring you see all 100% of the proposed changes. This initial step leverages Atlas's VCS layer to expose `status`, `diff`, `diffRaw`, and `commits` data directly from your Git repository, providing a foundational understanding of the modifications.

When you instruct Atlas to review a pull request in your Tauri project, it starts by interacting with your Git repository. Atlas's internal VCS layer is designed to mirror a human developer's workflow, allowing it to fetch the target branch and then produce a detailed diff. This diff is not just a simple line-by-line comparison; it's the raw patch that forms the basis of the review. Atlas uses its `bash` tool to execute the necessary Git commands, ensuring that all changed files and their modifications are accurately identified. This initial phase is crucial for setting the stage for a thorough review, as it provides Atlas with the exact scope of the changes across your `src-tauri` directory and frontend `package.json` files.

## Gaining Full Context for Tauri Code Changes

Atlas moves beyond simple diff hunks to provide a complete understanding of Tauri code changes by reading entire files, not just the modified sections, a critical step for catching subtle bugs. This approach ensures that you can see how a change in a `src-tauri/capabilities` file or a Rust `#[tauri::command]` handler impacts surrounding logic, even if those lines were not directly part of the 1-line diff.

A line-by-line diff often hides crucial context, especially in complex Tauri applications where Rust core logic interacts with the webview frontend. Atlas addresses this by using its `read` tool to pull the full content of every changed file. For instance, if a modification occurs within a `src-tauri/main.rs` file, Atlas will load the entire `main.rs` file, allowing its agents to analyze the change within its complete functional scope. This is particularly important for Tauri's `#[tauri::command]` handlers and the corresponding `invoke` calls on the JavaScript side, where a small change can have cascading effects. Furthermore, for every changed Rust function signature, Atlas employs the `lsp` tool's `findReferences` operation. This powerful capability checks whether a modified signature broke any callers that the raw diff might not have shown, providing an essential safety net for Rust code integrity.

## Verifying Tauri Application Behavior and Permissions

Atlas rigorously verifies Tauri application behavior by running `cargo test` for the Rust core and the frontend test suite, all behind a permission prompt, ensuring no unauthorized actions occur. This comprehensive testing, combined with `grep` for unupdated patterns, helps catch issues like stale constant names or missing capability entries in `src-tauri/capabilities` that a developer might overlook in a 2026 codebase.

After understanding the context, Atlas proceeds to validate the changes. It uses its `grep` tool to search for patterns that should have been updated but were not, such as old constant names, stale copies of code, or feature flags that might have been missed. Crucially, Atlas then executes the project's tests. For the Rust core, it runs `cargo test` within the `src-tauri` directory. For the frontend, it executes the appropriate test suite, often managed by `pnpm` as part of the `cargo (with pnpm frontend)` setup. Every test run is permission-gated, meaning Atlas will ask for your approval before executing these commands, maintaining strict control over your environment. This step is vital for Tauri applications, where a missing permission in `src-tauri/capabilities` can lead to silent runtime failures, making automated testing and permission checks indispensable.

## Ensuring Code Quality and Safety in Tauri Reviews

Atlas prioritizes code quality and safety in Tauri pull request reviews by drafting a plan in a read-only agent and presenting a unified diff for every file edit, requiring your explicit approval before writing. This meticulous process includes running `rustfmt` on the Rust side and `prettier` on the frontend, ensuring that all 100% of the code adheres to established formatting standards before a commit is finalized.

Atlas's review process is built with safety and quality at its core. Before making any modifications, Atlas drafts a plan in a read-only plan agent, which it presents to you for approval. This ensures transparency and allows you to understand the agent's intended actions. When Atlas proposes an edit, such as applying formatting or fixing a bug, it computes a unified diff for every file change and surfaces it for your approval. This granular control means you always have the final say before any code is written to your disk. After approving the core changes, Atlas can then run `rustfmt` on the Rust files within `src-tauri` and `prettier` on the frontend files, ensuring consistent code style across the entire Tauri project. Atlas also snapshots file changes as Git patches, allowing edits to be easily diffed and rolled back if necessary, providing an additional layer of safety.

## Tauri-Specific Setup and Capability Management with Atlas

Atlas is designed to direct integrate with Tauri projects, recognizing key files like `src-tauri/tauri.conf.json` and the frontend `package.json` from the moment you start it in 2026. This deep understanding extends to reading `#[tauri::command]` handlers, JavaScript `invoke` calls, and permissions defined in `src-tauri/capabilities`, enabling Atlas to assist with complex tasks like wiring a new command and its corresponding capability entry.

To leverage Atlas for Tauri development, you simply run it within your project directory. Atlas automatically detects the presence of `src-tauri/tauri.conf.json` and a frontend `package.json`, immediately understanding the project's structure. It's capable of parsing your Rust code to identify `#[tauri::command]` handlers and analyzing your JavaScript to find `invoke` calls. Crucially, Atlas also reads and understands the permissions defined in your `src-tauri/capabilities` files. This allows it to not only review existing code but also to assist in development tasks. For example, if you need to expose a new command, you can ask Atlas to wire the matching capability entry. This is a significant advantage, as a missing permission in Tauri fails silently at runtime, making Atlas's ability to manage and verify these entries invaluable for preventing hard-to-debug issues.

## Steps

1. Initiate the review: Atlas fetches the pull request branch and uses its `bash` tool to produce the raw Git diff, identifying all changed files across your Tauri project.
2. Read full file context: Atlas employs its `read` tool to load the complete content of every changed file, including `src-tauri/main.rs` and frontend components, providing context beyond the diff hunks.
3. Check Rust signature integrity: For any changed Rust function signatures in `src-tauri`, Atlas runs the `lsp` tool's `findReferences` operation to detect broken callers not visible in the diff.
4. Scan for missed updates: Atlas uses `grep` to search for patterns like old constant names or stale feature flags that should have been updated but were overlooked in the changes.
5. Validate permissions: Atlas analyzes `src-tauri/capabilities` to ensure all `#[tauri::command]` handlers and `invoke` calls have correctly wired permissions, preventing silent runtime failures.
6. Run comprehensive tests: Atlas prompts for permission, then executes `cargo test` in `src-tauri` for the Rust core and the frontend test suite via `cargo (with pnpm frontend)`.
7. Review findings and approve: Atlas compiles all findings into a `todowrite` list ordered by severity, presenting a unified diff for any proposed fixes for your approval.
8. Apply formatting: Upon approval, Atlas runs `rustfmt` on the Rust files in `src-tauri` and `prettier` on the frontend files to ensure consistent code style.
