How does Atlas handle Vue single-file components (.vue files) during an audit?

Atlas indexes code by AST declarations using tree-sitter, which allows it to understand the structure of `.vue` single-file components, including their script, template, and style sections. This enables precise targeting of specific parts of your Vue components during an audit, rather than relying on blind line windows. Subagents can use `glob 'src/**/*.vue'` to specifically target these files.

Can Atlas help migrate a Vue 2 project to the Composition API in 2026?

Yes, Atlas can assist with migrating to the Composition API. While auditing, you can ask Atlas to identify areas suitable for migration or even draft changes. Atlas will present a unified diff for review before applying any modifications to your `.vue` files, ensuring you maintain full control over the migration process.

What Vue testing framework does Atlas support for audits?

Atlas fully supports `Vitest with Vue Test Utils` as the test runner for Vue projects. During an audit, Atlas subagents can be instructed to run `pnpm test` to gather test results or analyze test files for specific patterns, integrating direct with your existing testing setup.

How does Atlas prevent accidental changes during a Vue repository audit?

Atlas employs several safety measures. For audits, the `explore` subagent type is deny-by-default and read-only, preventing any file modifications. Additionally, Atlas drafts a plan in a read-only plan agent for approval, computes a unified diff for every proposed edit to `.vue` files or `package.json`, and snapshots changes as git patches for easy rollback, ensuring no changes occur without explicit developer consent.

Can Atlas audit specific parts of my Vue project, like only Pinia stores?

Absolutely. Atlas allows you to split your audit into independent slices. You can launch a dedicated subagent using the `task` tool, instructing it to focus solely on your Pinia stores, typically located in `src/stores/`. This targeted approach ensures efficient and relevant auditing without unnecessary context.

Does Atlas integrate with `pnpm` for managing Vue project dependencies?

Yes, Atlas integrates directly with `pnpm` as the package manager for Vue projects. Atlas reads your `package.json` and understands `pnpm` commands. While `explore` subagents are read-only, a `general` subagent, with permission, could execute `pnpm install` or other `pnpm` commands if required for a more active audit or fix.

Audit a Vue.js Repository with Parallel Subagents in Atlas, 2026

Atlas empowers Vue developers in 2026 to sweep an entire repository for a class of problems without overwhelming the main session's context window by fanning out work to parallel subagents. This approach allows Atlas to efficiently audit large Vue.js codebases, identifying issues across `.vue` components, stores, and routers, while respecting the project's established toolchain, including `Vitest with Vue Test Utils` for testing, `pnpm` for package management, and `prettier` for code formatting. By splitting the audit into independent slices, Atlas ensures that each subagent focuses on a specific part of the codebase, returning only its conclusions to the main session.

How Atlas Parallel Subagents Audit Vue Codebases Efficiently

In 2026, Atlas addresses the challenge of large Vue.js repository audits by deploying parallel subagents, preventing the main session's context window from being overwhelmed. This strategy allows Atlas to process extensive codebases, such as those with hundreds of `.vue` single-file components, by distributing the workload.

Atlas's core capability for auditing large Vue.js repositories lies in its ability to fan out work to subagents that can run concurrently. When a Vue developer initiates an audit, Atlas uses the `task` tool to launch multiple subagents, each operating in its own isolated session. This means that the extensive file dumps and intermediate thoughts of each subagent never enter the main session's context window; only their final conclusions are returned. For a read-only sweep, the `explore` subagent type is ideal, as it is deny-by-default and cannot make changes, ensuring the integrity of the Vue project. This method is particularly effective for sweeping a Vue project for specific issues, like identifying deprecated Composition API usages or ensuring consistent `prettier` formatting across all `.vue` files, without bogging down the primary Atlas session.

Splitting Vue Repository Audits for Concurrent Execution

To maximize efficiency in 2026, Atlas recommends splitting a Vue.js repository audit into independent slices, allowing subagents to run concurrently. A typical Vue project can be divided by directories like `src/components`, `src/stores`, or `src/views`, ensuring each subagent has a distinct, non-overlapping scope.

Auditing a Vue.js repository with parallel subagents begins by strategically dividing the codebase into manageable, independent slices. For instance, a developer might instruct Atlas to audit all `.vue` components in `src/components` for accessibility issues, while simultaneously auditing `src/stores` for Pinia store best practices, and `src/router` for Vue Router configuration errors. Atlas's `task` tool is then used to launch one subagent per slice. By issuing these `task` calls together, Atlas ensures they run concurrently rather than sequentially, drastically reducing the total audit time. Each subagent, often an `explore` type for read-only sweeps, uses Atlas's `grep` and `glob` tools to efficiently search within its assigned slice, for example, `glob 'src/components/**/*.vue'` to target all component files.

Concrete Atlas Commands for Vue Audits and Toolchain Integration

Atlas integrates directly with the Vue.js ecosystem in 2026, allowing developers to use real commands like `pnpm install` and `pnpm test` within agent workflows. For an audit, Atlas leverages its `task` tool to orchestrate subagents, which can then utilize `grep` to find specific patterns in `.vue` files.

When auditing a Vue.js repository, Atlas understands and interacts with the project's native toolchain. For example, a subagent tasked with verifying test coverage might be instructed to run `pnpm test` using `Vitest with Vue Test Utils` to gather results. Similarly, to check for `prettier` compliance, a subagent could be configured to identify files that would be modified by `prettier --write 'src/**/*.vue'`. Atlas's `task` tool is central to this, launching subagents that can then execute these commands or use Atlas's internal `grep` and `glob` tools. For instance, to find all instances of a specific deprecated Vue 2 API in a Vue 3 project, an Atlas subagent could run `grep -r 'Vue.set' src/components/` within its assigned directory slice. Atlas reads `package.json` to understand project dependencies and scripts, ensuring its actions are always contextually relevant to the Vue environment.

Ensuring Safety and Review in Vue Repository Audits with Atlas

Atlas prioritizes safety in 2026 Vue.js repository audits through a multi-layered review process, ensuring no changes are made without explicit developer approval. Every Atlas tool call is permission-gated, and a read-only plan agent drafts actions before any build agent can execute them.

Safety is paramount when auditing a Vue.js repository, and Atlas provides robust mechanisms to ensure control and transparency. Every Atlas tool call, whether it's `grep` or a potential `edit`, is permission-gated against allow, ask, and deny rules. Before any action is taken, Atlas drafts a plan in a read-only plan agent and asks for approval, preventing unintended modifications. For audit tasks, using the `explore` subagent type is a key safety feature, as it is deny-by-default and strictly read-only, meaning it cannot execute commands that alter files or run `pnpm install` or `prettier --write`. If a `general` subagent is used and proposes changes, Atlas computes a unified diff for every file edit, such as changes to a `.vue` component or a `package.json` script, and surfaces it for approval before writing. Furthermore, Atlas snapshots file changes as git patches, allowing edits to be easily diffed and rolled back, providing a secure environment for even the most extensive Vue codebase audits.

Step by step

01Identify independent slices within your Vue.js repository, such as `src/components`, `src/stores`, or `src/views`, to distribute the audit workload effectively among subagents.
02Launch multiple read-only `explore` subagents concurrently using the Atlas `task` tool, assigning each a specific slice. For example, `task --subagent-type explore 'Audit src/components for deprecated APIs' --glob 'src/components/**/*.vue'`.
03Instruct each subagent to use Atlas's `grep` tool to search for specific patterns or issues relevant to its slice, such as `grep -r 'old-api-call' src/components/` within a component-focused subagent.
04Collect each subagent's final message, which Atlas's `task` tool surfaces. This includes any findings or error texts, ensuring you receive clear conclusions from each parallel audit.
05Merge the collected findings into a unified `todowrite` list in your main Atlas session. This consolidates all identified issues from across your Vue.js repository.
06Address the identified issues in your main session using Atlas's `edit` tool, reviewing each proposed change with a unified diff before applying it to your `.vue` files or `package.json`.
