How does Atlas prevent accidental edits in my Electron project during planning?

Atlas uses a dedicated plan agent with strict permissions that deny all edit tools for every file in your Electron project, except for a specific plan markdown file under `.atlas/plans/*.md`. This read-only mode ensures you can research and design without any risk of unintended code modifications.

Can Atlas help me understand my Electron app's `ipcMain.handle` and `ipcRenderer.invoke` calls?

Yes, Atlas can read your main process, preload script, and every `ipcRenderer.invoke` call paired to an `ipcMain.handle`. Its `codebase_search` and `lsp` tools are particularly effective for navigating and understanding these inter-process communication patterns within your Electron application.

How do I ensure my Electron security model (e.g., `contextIsolation`) is respected with Atlas?

Atlas encourages and helps you maintain Electron's security model. During planning, you can specify how changes will leverage `contextBridge.exposeInMainWorld` in your `preload.js` script, rather than compromising `contextIsolation` or enabling `nodeIntegration` in the renderer. Atlas can also confirm `nodeIntegration` stayed off after changes.

What Electron-specific tools does Atlas integrate with?

Atlas integrates direct with your existing Electron toolchain. It works with `npm` for package management, `prettier` for code formatting, and helps you write and run `@playwright/test` cases to drive your packaged Electron application, ensuring a familiar development experience.

What happens if I decide not to implement a plan after drafting it with Atlas?

If you decide not to proceed with a plan, you can answer 'No' when prompted by the `plan_exit` tool. This will raise a `Question.RejectedError` and keep you in the plan agent, allowing you to refine your existing plan or discard it without ever modifying your Electron codebase.

Can Atlas help me move a Node.js API out of the Electron renderer process?

Absolutely. Atlas can assist in planning and implementing the secure relocation of Node.js APIs. It can help you move a Node API out of the renderer and behind `contextBridge.exposeInMainWorld` in your `preload.js` script, enhancing your Electron application's security by maintaining `contextIsolation`.

Plan a Multi-File Change Before Editing in Electron with Atlas in 2026

To design a multi-file change in your Electron application and get it reviewed before modifying any code, Atlas provides a dedicated plan agent that operates in a read-only mode, ensuring no accidental edits. This agent allows you to research your codebase using tools like `codebase_search` and `lsp`, draft your proposed changes in a markdown file, and then present a comprehensive plan for review, all while interacting with your familiar Electron toolchain, including `npm` for package management, `prettier` for formatting, and `@playwright/test` for testing.

How Atlas's Plan Agent Secures Electron Codebase Design

Atlas's plan agent provides a secure, read-only environment for designing multi-file changes in your Electron application, ensuring no accidental modifications occur. This dedicated agent, available in 2026, strictly denies edit permissions for all files except a designated plan markdown document, offering a safe sandbox for architectural design.

When you initiate a multi-file change workflow with Atlas, you first switch to its specialized plan agent. This agent is engineered with a stringent permission set: it explicitly denies all edit tools for every path in your Electron project, with the sole exception of a markdown file located under `.atlas/plans/*.md`. This 'read-only' mode is a core safety feature, preventing any unintended code alterations while you are in the research and design phase. For an Electron developer, this means you can explore your `main.js` process, `preload.js` scripts, and `ipcRenderer.invoke` calls without the risk of inadvertently changing a critical security boundary like `contextIsolation` or `nodeIntegration`. The plan agent's design ensures that your focus remains entirely on conceptualizing the change, gathering information, and documenting your strategy, rather than worrying about premature or accidental code modifications.

Researching Electron Codebases with Atlas's Integrated Tools

Atlas integrates powerful research tools directly into its plan agent, allowing Electron developers to thoroughly understand their codebase before proposing any changes. You can use `codebase_search`, `grep`, `read`, and `lsp` to explore your project's structure and logic, ensuring a comprehensive understanding of how your 2026 Electron app functions.

Within the Atlas plan agent, you have access to a suite of powerful tools designed for deep codebase research. For an Electron project, this means you can use `codebase_search` to semantically locate relevant code sections across your `main` process, `renderer` process, and `preload` scripts. The `grep` tool allows for precise keyword searches, helping you find all instances of `ipcMain.handle` or `contextBridge.exposeInMainWorld` calls. The `read` tool lets you inspect the contents of specific files, such as `package.json` to check dependencies or `webpack.config.js` for build configurations. Furthermore, the `lsp` (Language Server Protocol) tool provides rich, language-aware insights, offering definitions, references, and type information for your TypeScript or JavaScript files, crucial for understanding complex interactions between the main and renderer processes. All these tools operate within the read-only constraints of the plan agent, providing a safe and comprehensive way to gather all necessary information about your Electron application's architecture and existing implementations.

Drafting Multi-File Electron Changes in Atlas's Plan Markdown

After thorough research, Atlas directs you to document your proposed multi-file Electron changes within a dedicated plan markdown file, the only location where the plan agent permits writing. This structured approach ensures your design, including considerations for `contextIsolation` and `preload` scripts, is clearly articulated before any implementation begins in 2026.

Once you have completed your research using Atlas's tools, the next step is to articulate your proposed multi-file change. The plan agent is specifically configured to allow writing only to a markdown file within the `.atlas/plans/` directory. This is where you will draft your detailed plan, outlining the modifications you intend to make across your Electron application. For instance, if you're planning to move a Node.js API out of the renderer process and expose it securely via `contextBridge.exposeInMainWorld` in your `preload.js` script, your plan markdown would detail the specific changes to `main.js`, `preload.js`, and any affected renderer-side scripts. You would also specify how you intend to update `@playwright/test` cases to reflect these changes, and how `prettier` will be used to maintain code style. This structured documentation ensures that your design is clear, comprehensive, and ready for review, serving as a blueprint for the subsequent implementation phase.

Reviewing and Approving Electron Change Plans with Atlas

Atlas streamlines the review process for your Electron change plans by generating a unified diff for every proposed file edit, even before a single line is written to your codebase. When your plan is complete, the `plan_exit` tool prompts for approval, ensuring that your multi-file design, perhaps involving 3 or more files, is thoroughly vetted before implementation begins.

The review and approval process is a critical safety gate in Atlas's workflow for Electron development. As you refine your plan in the `.atlas/plans/*.md` file, Atlas can snapshot these proposed changes as git patches, allowing you to visualize the impact of your design. When you are satisfied with your detailed plan, you invoke the `plan_exit` tool. This tool presents a clear prompt: 'Plan at <path> is complete. Would you like to switch to the build agent and start implementing?' Answering 'Yes' signals your approval and transitions Atlas to the build agent, which has the necessary permissions to begin implementing the changes outlined in your plan. Answering 'No' raises a `Question.RejectedError`, keeping you in the plan agent to further refine your design. This explicit approval step ensures that all stakeholders can review the proposed multi-file changes, including how they affect Electron's security model (like `contextIsolation` or `nodeIntegration`), before any actual code modification takes place, providing a robust safety mechanism.

Ensuring Electron-Specific Safety and Toolchain Integration

Atlas is designed to integrate direct with the Electron toolchain, ensuring that critical security considerations like `contextIsolation` and `nodeIntegration` are maintained throughout your planning and implementation. In 2026, Atlas helps you verify that your proposed changes align with best practices, leveraging `npm` for dependencies and `prettier` for consistent code formatting.

A key advantage of using Atlas for Electron development is its deep understanding and integration with the Electron ecosystem. During the planning phase, Atlas encourages you to consider how your multi-file changes will impact Electron's security model, particularly the separation between the main and renderer processes, `contextIsolation`, and the use of `preload` scripts. For example, if your plan involves moving a Node.js API out of the renderer process and exposing it safely via `contextBridge.exposeInMainWorld` in your `preload.js` script, your plan markdown would detail the specific changes to `main.js`, `preload.js`, and any affected renderer-side scripts. Atlas also understands the importance of your existing toolchain. It expects your project to use `npm` for managing `package.json` dependencies and `prettier` for maintaining code style. After any proposed changes are implemented, Atlas can be instructed to run `prettier` to format the modified files and confirm that crucial settings like `nodeIntegration` remain off, ensuring your Electron application adheres to both security best practices and your team's coding standards.

Step by step

01Initialize Atlas in your Electron project by ensuring your `package.json`'s `main` field points to your Electron entry file, allowing Atlas to read your main process, preload script, and `ipcRenderer.invoke` calls.
02Switch to the Atlas plan agent to enter a read-only design mode, where permissions deny all edits except to your plan markdown file under `.atlas/plans/*.md`.
03Research your Electron codebase using Atlas's `codebase_search`, `grep`, `read`, and `lsp` tools to understand existing `ipcMain.handle` implementations, `contextBridge.exposeInMainWorld` patterns, and overall architecture.
04Draft your multi-file change plan into the allowed markdown file, detailing proposed modifications to `main.js`, `preload.js`, renderer scripts, and how `@playwright/test` cases will be updated.
05Review the proposed plan, ensuring it addresses Electron-specific security concerns like `contextIsolation` and avoids enabling `nodeIntegration` in the renderer process.
06Call the Atlas `plan_exit` tool; review the prompt 'Plan at <path> is complete. Would you like to switch to the build agent and start implementing?' and confirm 'Yes' to proceed to implementation, or 'No' to refine the plan further.
07Upon approval, Atlas transitions to the build agent, ready to implement the changes, potentially moving a Node API behind `contextBridge.exposeInMainWorld` as outlined in your plan.
08After implementation, review the unified diff generated by Atlas, then instruct Atlas to run `prettier` on modified files and confirm that `nodeIntegration` remains off, ensuring code quality and security.
