How does Atlas prevent context window overflow when auditing a large Electron app?

Atlas prevents context window overflow by fanning out audit tasks to parallel subagents. Each subagent operates in its own session, meaning its extensive file dumps and intermediate thoughts never enter your main Atlas session's context. Only the subagent's final conclusions are returned, keeping your primary context clear and focused.

Can Atlas ensure my Electron audit is read-only and doesn't accidentally modify files?

Yes, Atlas ensures read-only audits by allowing you to specify `subagent_type explore` when launching tasks. This subagent type is deny-by-default and read-only, meaning it cannot execute commands or write files, providing a safe environment for sweeping your Electron codebase for issues.

How does Atlas handle Electron's `contextIsolation` and `preload` scripts during an audit?

Atlas is designed to understand Electron's security model. It can read your `main` process, `preload` script, and analyze `ipcRenderer.invoke` calls paired with `ipcMain.handle`. This allows it to identify and suggest moving Node APIs out of the renderer and behind `contextBridge.exposeInMainWorld` in the `preload` script, reinforcing `contextIsolation`.

What Electron-specific tools does Atlas integrate with for auditing and fixing?

Atlas integrates directly with standard Electron development tools. It understands your `package.json` structure, can write `@playwright/test` cases to validate changes, and can run `prettier` to format your code. It also helps confirm critical settings like `nodeIntegration` remain off.

How does Atlas help me review and approve changes to my Electron codebase?

Atlas provides robust review mechanisms. For every proposed file edit, it computes and surfaces a unified diff for your explicit approval. This allows you to carefully inspect changes, especially in security-sensitive areas of your Electron application, before they are written to disk.

Can Atlas help me write `@playwright/test` cases for my Electron application?

Yes, Atlas can write `@playwright/test` cases that drive your packaged Electron app. These tests can be generated to run behind a permission prompt, allowing you to validate fixes and ensure the continued security and functionality of your application, such as confirming `nodeIntegration` remains off.

What happens if an Atlas subagent fails during an Electron audit?

If an Atlas subagent encounters an error during an Electron audit, the `task` tool will surface the child's error text verbatim. If the subagent's task was cancelled, it will report "Task cancelled." This provides clear feedback on the status of each parallel audit slice.

Audit an Electron Repository with Parallel Subagents in Atlas in 2026

Atlas enables Electron developers in 2026 to sweep an entire repository for a class of problems without blowing the main session's context window by leveraging parallel subagents. This process involves splitting the audit into independent slices, launching concurrent tasks with `subagent_type explore` for read-only sweeps, and then merging findings into a `todowrite` list for fixes using `edit`. Atlas integrates directly with your Electron project's `package.json`, understands `ipcRenderer.invoke` and `ipcMain.handle` pairings, and can even write `@playwright/test` cases to validate changes, ensuring your `nodeIntegration` remains off and code is formatted with `prettier`.

How to Audit Electron Codebases with Parallel Atlas Subagents

Auditing large Electron codebases in 2026 for specific issues, like improper `contextBridge` usage or `nodeIntegration` flags, is efficiently handled by Atlas's parallel subagents. These subagents can concurrently sweep up to 10 distinct directories or modules, preventing the main session's context window from being overwhelmed.

Atlas's core strength for Electron audits lies in its ability to fan out work to multiple subagents. When sweeping an Electron repository, you can define independent slices of your codebase,perhaps by `src/main`, `src/renderer`, or specific feature modules. Each slice is then assigned to a dedicated subagent. For instance, one subagent might focus on `preload.js` files to ensure `contextBridge.exposeInMainWorld` is correctly implemented, while another scans `main.js` for `ipcMain.handle` calls. This parallel execution, managed by the `task` tool, means that the extensive file contents and intermediate thoughts of each subagent never enter your main Atlas session's context window. Only their final conclusions or error messages are returned, keeping your primary focus clear and efficient. This approach is particularly valuable for Electron's split main and renderer processes, where distinct security concerns often require separate, focused audits.

Launching Concurrent Read-Only Sweeps in Electron Projects

To perform a secure, read-only audit of your Electron project, Atlas utilizes the `subagent_type explore` flag with the `task` tool. This ensures that subagents operate under a deny-by-default policy, preventing any unintended modifications to your `package.json` or source files. You can launch 5 or more such tasks simultaneously.

When auditing an Electron application, maintaining the integrity of your codebase is paramount. The `explore` subagent type is specifically designed for this. It's a read-only agent, meaning it cannot execute commands or write files, making it ideal for initial sweeps for issues like `nodeIntegration: true` in `webPreferences` or direct Node.js API access in renderer processes. You would use the `task` tool to launch these subagents, specifying `subagent_type explore`. For example, one task might `grep` for `nodeIntegration: true` across all `BrowserWindow` instantiations, while another uses `glob` to find all `ipcRenderer.invoke` calls in `src/renderer` and verifies their corresponding `ipcMain.handle` in `src/main`. By issuing these `task` calls together, Atlas runs them concurrently, significantly accelerating the audit process compared to sequential execution.

Identifying and Addressing Electron Security Vulnerabilities

Atlas helps identify common Electron security vulnerabilities, such as direct Node.js API access in the renderer process, by analyzing `ipcRenderer.invoke` and `ipcMain.handle` pairings. In 2026, ensuring `contextIsolation` is enabled and `nodeIntegration` is disabled by default is a critical first step for any secure Electron application.

A key aspect of auditing an Electron application is verifying its security model, which revolves around `contextIsolation`, `preload` scripts, and the `ipcRenderer`/`ipcMain` communication. Atlas can be instructed to read your `main` process, `preload` script, and every `ipcRenderer.invoke` call paired to an `ipcMain.handle`. For instance, an audit might focus on identifying any `require` statements or direct Node.js API calls within `src/renderer/index.js` or other renderer-side scripts. Atlas can then suggest moving such Node APIs out of the renderer and behind `contextBridge.exposeInMainWorld` in the `preload` script, ensuring secure, controlled access. After the subagents complete their sweeps, their findings are collected. If a subagent identifies a potential vulnerability, its conclusion will be surfaced, allowing you to use the `todowrite` tool to compile a list of necessary fixes and then `edit` to implement them in the main session.

Reviewing and Committing Electron Code Changes with Atlas

After Atlas subagents identify and propose fixes for Electron-specific issues, the main session provides robust review mechanisms. Every file edit generates a unified diff for approval, and Atlas can automatically run `prettier` to ensure code style consistency before committing changes in 2026.

Once the parallel subagents have completed their read-only sweeps and you've used `todowrite` to consolidate findings, Atlas assists in the remediation phase. When you instruct Atlas to `edit` files, it first drafts a plan in a read-only plan agent and asks for your approval before switching to a build agent. For every proposed file edit, such as modifying `webPreferences` in `main.js` or adjusting a `preload.js` script, Atlas computes a unified diff and surfaces it for your explicit approval. This granular control is crucial for Electron projects, where changes to security-sensitive areas like `contextIsolation` or `nodeIntegration` require careful review. After your approval, Atlas can be asked to run `prettier` across the modified files, ensuring your codebase adheres to established formatting standards. Finally, Atlas reads `git` branches, status, and diffs, and can stage and create commits on your behalf, even snapshotting file changes as `git` patches for easy rollback.

Step by step

01Initialize Atlas in your Electron project: Ensure your Electron application has a `package.json` whose `main` field correctly points to your Electron entry file, such as `main.js`. Launch Atlas from the terminal within this project directory.
02Define audit slices for parallel subagents: Split your Electron repository into logical, independent slices for the audit. For example, you might define slices for `src/main`, `src/renderer`, `src/preload`, or specific feature directories.
03Launch concurrent read-only audit tasks: Use the Atlas `task` tool to launch multiple subagents concurrently, each assigned to a specific slice. For a read-only sweep, specify `subagent_type explore`. For instance, `atlas task "grep for nodeIntegration: true in src/main" subagent_type explore` and `atlas task "glob for ipcRenderer.invoke calls in src/renderer" subagent_type explore`.
04Collect subagent findings: After the subagents complete their tasks, Atlas will surface their final messages, including any identified issues or error texts. Review these conclusions to understand the scope of problems found in your Electron codebase.
05Consolidate findings into a `todowrite` list: Use the Atlas `todowrite` tool to compile a unified list of all identified Electron-specific problems, such as improper `contextBridge` usage or `nodeIntegration` flags, based on the subagents' reports.
06Implement fixes with Atlas `edit`: Instruct Atlas to `edit` the relevant Electron files to address the issues in your `todowrite` list. For example, ask Atlas to move a Node API out of the renderer and behind `contextBridge.exposeInMainWorld` in your `preload.js` script.
07Review and approve proposed changes: Atlas will present a unified diff for every file edit. Carefully review these changes, especially those affecting `contextIsolation` or `nodeIntegration` settings in your `main.js` or `webPreferences`, and approve them before Atlas writes to disk.
08Format code and commit changes: After approving edits, ask Atlas to run `prettier` on the modified files to ensure consistent formatting. Then, let Atlas stage and create a `git` commit on your behalf, ensuring all changes are properly recorded and can be rolled back if needed.
