How does Atlas understand Tauri permissions in `src-tauri/capabilities`?

Atlas indexes the `src-tauri/capabilities` files as part of its AST declarations, allowing it to understand and even help wire new capability entries for `#[tauri::command]` handlers, preventing silent runtime failures.

Can Atlas run `cargo test` in my Tauri project?

Yes, Atlas can run `cargo test` in your `src-tauri` directory and also execute your frontend test suite. All test runs are permission-gated, requiring your explicit approval before execution.

What specific Tauri files does Atlas index for semantic search?

Atlas indexes your Rust core files, webview frontend files, `#[tauri::command]` handlers, JavaScript `invoke` calls, and the critical `src-tauri/capabilities` files to build a comprehensive semantic model.

How does Atlas help with `#[tauri::command]` definitions and usage?

Atlas understands `#[tauri::command]` handlers and their corresponding `invoke` calls on the JS side. It can semantically search for them, trace their definitions using `lsp`, and even assist in exposing new commands and wiring their capabilities.

Is it safe to let Atlas modify my Tauri code?

Yes, Atlas is designed for safety. It drafts plans in a read-only agent, requires explicit permission for every tool call, and computes a unified diff for every proposed file edit, which you must approve before any changes are written to your Tauri codebase.

Can Atlas format my Tauri Rust and frontend code?

Absolutely. Atlas can run `rustfmt` on your Rust code within `src-tauri` and `prettier` on your frontend code. It will present the generated diff for your review and approval before applying any formatting changes.

How does Atlas handle `pnpm` as a frontend package manager in a Tauri project?

Atlas recognizes `cargo` as the primary package manager for Rust, and it supports frontend package managers like `pnpm` through its `bash` tool. It can run frontend test suites and formatting commands that rely on `pnpm` behind permission prompts.

How does Atlas help me understand the overall structure of an unfamiliar Tauri project?

Atlas uses `glob` to quickly map top-level directories like `src-tauri` and `frontend`, and `read` to inspect key configuration files like `src-tauri/tauri.conf.json` and `package.json`, providing a rapid overview of the project's architecture.

Onboard to an Unfamiliar Tauri Codebase with Atlas in 2026

In 2026, Atlas helps Tauri developers quickly build a working mental model of unfamiliar codebases by starting from meaning, not filenames, and leveraging real Tauri toolchain commands like `cargo test` and `rustfmt` for verification and formatting. It indexes `#[tauri::command]` handlers, JS `invoke` calls, and the critical permissions defined in `src-tauri/capabilities` to provide deep, actionable insights.

How Atlas builds a mental model of a Tauri codebase

Atlas helps you build a working mental model of an unfamiliar Tauri codebase in 2026 by starting from meaning, not just filenames. It semantically indexes your Rust core, webview frontend, and `src-tauri/capabilities` files, allowing you to query complex concepts directly, often reducing initial exploration time by 50% or more.

Atlas begins by indexing your Tauri project's Abstract Syntax Tree (AST) declarations using tree-sitter, rather than relying on blind line windows. This allows `codebase_search` to perform hybrid semantic and keyword retrieval, fused by reciprocal rank fusion, for concepts like how requests are authenticated or how a specific `#[tauri::command]` handler operates. Atlas understands the unique structure of Tauri applications, including the Rust core, the webview frontend, and the crucial `src-tauri/capabilities` files that define what your application is permitted to do. By querying the semantic index, you can quickly identify relevant code snippets and file paths related to `invoke` calls on the JavaScript side or specific Rust functions, without needing to manually open and read every file in the repository.

Exploring Tauri project structure and permissions with Atlas

Understanding the layout of a Tauri project is crucial, and Atlas streamlines this in 2026. The `glob` tool quickly maps top-level directories like `src-tauri/` and `frontend/`, providing a high-level overview in just a few seconds. This initial structural insight is vital before diving into specific files.

After an initial semantic search, Atlas helps you understand the physical layout of your Tauri project. The `glob` tool allows you to inspect the top-level directories, revealing the package structure and naming conventions, such as the distinct `src-tauri/` directory for the Rust backend and the `frontend/` directory for the webview. Once you have identified key files from `codebase_search` or `glob`, the `read` tool pulls only the files that actually matter, such as `src-tauri/tauri.conf.json` for configuration or `package.json` for frontend dependencies. For deeper exploration, the `lsp` tool's `goToDefinition` operation allows you to follow imports and function definitions, tracing the flow from a JavaScript `invoke` call to its corresponding `#[tauri::command]` handler in Rust, or understanding how permissions are wired in `src-tauri/capabilities`. Atlas is designed to expose a new command and wire the matching capability entry, since a missing permission fails silently at runtime, a common pitfall for Tauri developers.

Verifying Tauri code changes and ensuring safety with Atlas

Atlas ensures safety and verifiability when working with Tauri code in 2026. Every Atlas tool call is permission-gated, and all proposed file edits generate a unified diff for your approval. This robust review process means you maintain full control over any changes, even when delegating complex tasks to subagents.

Atlas operates with a strong emphasis on safety and user control. It drafts a plan in a read-only plan agent, asking for your approval before switching to a build agent that can make changes. Every tool call, including those that might interact with your Tauri project, is permission-gated against allow, ask, and deny rules. When Atlas proposes any file edit, it computes a unified diff and surfaces it for your approval before writing to disk. This applies to running `cargo test` in `src-tauri` or the frontend test suite, both of which are executed behind a permission prompt. Similarly, when formatting code, Atlas will run `rustfmt` on the Rust side and `prettier` on the frontend, presenting the diff for your review. For wide sweeps or exploratory tasks, Atlas can fan out work to the `explore` subagent, which is defined with a deny-by-default permission set, allowing only safe operations like `grep`, `glob`, `read`, `bash`, `webfetch`, and `websearch`, ensuring it cannot inadvertently modify your Tauri codebase while looking around.

Step by step

01Run Atlas in your Tauri project, ensuring a `src-tauri/tauri.conf.json` and a `frontend/package.json` are present.
02Ask `codebase_search` a plain-language question, such as 'how are requests authenticated in this Tauri app?', to query the semantic index for relevant `#[tauri::command]` handlers or `invoke` calls.
03Run `glob` on the top-level directories (e.g., `src-tauri`, `frontend`) to quickly understand the package layout and naming conventions.
04Use `read` to inspect the two or three files `codebase_search` ranked highest, then follow imports or function definitions with the `lsp` tool's `goToDefinition` operation, especially for `#[tauri::command]` or `invoke` calls.
05Delegate wide sweeps to the `explore` subagent through the `task` tool, for example, 'task explore all files in src-tauri for database interactions', knowing it's permissioned read-only.
06Record what you learned about the Tauri codebase as a `todowrite` list, ensuring open questions survive into the next turn.
07If modifying, ask Atlas to expose a new `#[tauri::command]` and wire the matching capability entry in `src-tauri/capabilities`, as a missing permission fails silently at runtime.
08Let Atlas run `cargo test` in `src-tauri` and the frontend test suite, both behind a permission prompt, and approve the execution.
09Approve the diff, then let Atlas run `rustfmt` on the Rust side and `prettier` on the frontend to maintain code style.
