How does Atlas prevent context window overflow when auditing large PowerShell repositories?

Atlas prevents context window overflow by launching parallel subagents using the `task` tool. Each subagent runs in its own isolated session, meaning its extensive file dumps and intermediate processing never enter your main Atlas session's context. Only the concise conclusions or error messages are returned, preserving your primary context window for focused work on PowerShell modules and scripts.

Can Atlas audit specific PowerShell module directories or just the entire repo?

Yes, Atlas can audit specific PowerShell module directories. You define the scope for each subagent task, allowing you to target individual directories like `src/Modules/MyModule` or specific file patterns using `glob`. This granular control is essential for focused audits and efficient parallel processing across your PowerShell codebase.

What PowerShell tools does Atlas integrate with for code quality and testing?

Atlas integrates directly with key PowerShell tools for code quality and testing. It can clear `PSScriptAnalyzer` warnings, run `Invoke-Formatter` over diffs to maintain style, and execute `Invoke-Pester` on `.Tests.ps1` files behind a permission prompt to verify changes and ensure your automation remains honest.

Is it safe to let Atlas make changes to my PowerShell scripts during an audit?

For an audit where no changes should occur, you use the `explore` subagent type, which is deny-by-default and read-only. If you later decide to apply fixes, Atlas's `edit` tool computes a unified diff for every proposed change to your PowerShell scripts or modules, requiring your explicit approval before writing. This ensures 100% control and safety.

How does Atlas handle `CmdletBinding` and `SupportsShouldProcess` in PowerShell functions?

Atlas can be instructed to add `CmdletBinding` and `SupportsShouldProcess` to destructive PowerShell functions, ensuring they honor the `-WhatIf` parameter. This is part of its ability to understand and modify PowerShell's advanced function syntax, always presenting a diff for your review before committing the changes to your `.psm1` files.

Can Atlas help manage PowerShell module dependencies with `PSResourceGet`?

While the primary audit workflow focuses on code content, Atlas can read your exported cmdlets, param blocks, and the modules pinned in your requirements. This implies an understanding of your module's dependencies, which are typically managed with `PSResourceGet`. Atlas can leverage this understanding to inform its audit or assist in related tasks, always within its permission-gated framework.

What kind of issues can Atlas identify in PowerShell code during an audit?

Atlas can identify a wide range of issues in PowerShell code, including missing `CmdletBinding` attributes, functions lacking `SupportsShouldProcess` for destructive operations, `PSScriptAnalyzer` warnings, deprecated cmdlet usage, or any class of problem you define for the subagents to sweep for. Its hybrid semantic and keyword retrieval, combined with AST indexing, allows for precise problem detection.

Audit a PowerShell Repository with Parallel Subagents in Atlas in 2026

Atlas enables PowerShell developers in 2026 to sweep an entire repository for a class of problems without blowing the main session's context window by launching parallel subagents. This approach leverages Atlas's `task` tool to fan out work, ensuring that only the conclusions from read-only `explore` subagents return to your primary session, preserving its context while integrating direct with `Pester` for testing and `PSScriptAnalyzer Invoke-Formatter` for code quality.

How Atlas Audits PowerShell Repositories with Parallel Subagents

Atlas audits PowerShell repositories by launching multiple subagents in parallel, a core capability that prevents the main session's context window from being overwhelmed. In 2026, this means you can divide a large codebase into 10 or more independent slices, assigning each to a dedicated subagent for a focused, read-only sweep.

When auditing a PowerShell repository, Atlas utilizes its `task` tool to initiate subagents, which operate in their own isolated sessions. This design is crucial for large-scale sweeps, as it ensures that the extensive file dumps and intermediate thoughts of each subagent never enter your main Atlas session's context window. Instead, only their concise conclusions or error messages are returned. For a read-only audit, the `explore` subagent type is ideal, as it is deny-by-default and cannot make changes, providing a safe environment to identify issues across your `.psm1` module files or `.psd1` manifest definitions. This method allows you to concurrently examine multiple directories, PowerShell modules, or specific rule violations without the performance overhead or context limitations of a single, monolithic agent.

Splitting PowerShell Audit Tasks for Concurrency

To maximize efficiency when auditing a PowerShell repository, split the audit into independent slices, allowing Atlas to run 5 or more subagents concurrently. This strategy ensures that each subagent focuses on a distinct part of your codebase, such as a specific module directory or a set of advanced functions, preventing overlap and accelerating the overall sweep.

Effective auditing with Atlas in a PowerShell environment begins by segmenting your repository into manageable, independent units. For instance, you might split the audit by distinct module directories, such as `src/Modules/MyModuleA` and `src/Modules/MyModuleB`, or by specific types of files like all `.psm1` module files versus all `.psd1` manifest files. Each of these slices then becomes a target for a separate subagent. You can use Atlas's `glob` tool to identify these distinct paths, for example, `glob 'src/Modules/*/Public/*.ps1'` to target public functions within various modules. By issuing these `task` calls together, Atlas launches them concurrently, rather than sequentially, significantly reducing the total time required to sweep the entire repository. This parallel execution is a cornerstone of Atlas's ability to handle large PowerShell codebases efficiently without manual intervention for context management.

Launching Read-Only PowerShell Sweeps with Atlas Subagents

Launching read-only sweeps in PowerShell with Atlas subagents involves using the `task` tool with the `subagent_type explore` flag, ensuring no accidental modifications occur. This approach is perfect for auditing, as the `explore` subagent is deny-by-default, providing a secure environment to inspect your `.ps1` scripts and module files for specific problems in 2026.

For a repository audit where no changes should be made, the `explore` subagent type is the correct choice. When you invoke the `task` tool, you specify `subagent_type explore` to ensure the subagent operates in a read-only mode. For example, to sweep a specific PowerShell module directory for deprecated cmdlets, you might issue a command like `task 'Sweep src/Modules/MyModule for deprecated cmdlets' subagent_type explore`. The subagent will then use tools like `grep` and its internal code index, built with local Ollama embeddings from AST declarations, to identify relevant code patterns within that module. This process keeps your code off third-party servers and ensures that every tool call made by the subagent is permission-gated, providing an additional layer of safety. The `explore` subagent will return its findings, which might include a list of files and line numbers, without ever attempting to modify any `.psm1` or `.psd1` files.

Collecting and Merging Subagent Findings for PowerShell

After launching parallel subagents to audit your PowerShell codebase, Atlas automatically collects each subagent's final message, whether it's a success or a detailed error. This streamlined collection process allows you to merge findings from 5 or more concurrent sweeps into a single, actionable `todowrite` list within your main session.

Once all subagents have completed their assigned audit slices, Atlas consolidates their outputs. Each subagent's final message, which could be a summary of findings, a list of identified issues, or an error text if the task failed, is surfaced directly to your main Atlas session. If a subagent task was cancelled, Atlas explicitly reports 'Task cancelled'. This aggregation is critical for gaining a holistic view of your PowerShell repository's health. You can then use Atlas's `todowrite` tool to compile these disparate findings into a unified list of items that require attention. For example, if one subagent found missing `CmdletBinding` attributes in `PublicFunctions.ps1` and another identified `PSScriptAnalyzer` warnings in `PrivateHelpers.psm1`, both would be added to your `todowrite` list. This consolidated list then serves as the basis for subsequent fixes, which you can address in the main session using the `edit` tool, ensuring a structured and trackable remediation process.

Reviewing and Applying Fixes in PowerShell with Atlas

Reviewing and applying fixes in your PowerShell codebase with Atlas involves using the `edit` tool to address issues identified by subagents, always with explicit approval. Atlas computes a unified diff for every proposed file edit, allowing you to review changes to your `.ps1` scripts or `.psm1` modules before they are written, ensuring 100% control over your codebase.

After collecting the findings from your parallel subagent audits and consolidating them into a `todowrite` list, the next step is to review and apply the necessary fixes. Atlas's `edit` tool facilitates this process by allowing you to make targeted modifications based on the audit results. For instance, if an audit revealed that a destructive function in `MyModule.psm1` lacks `CmdletBinding` and `SupportsShouldProcess`, you can instruct Atlas to add these attributes. Before any changes are written to disk, Atlas computes a unified diff, presenting it for your approval. This critical step ensures that you have full visibility and control over every modification, whether it's adding a `param` block, updating a `Pester` test in a `.Tests.ps1` file, or clearing `PSScriptAnalyzer` warnings. Atlas can even run `Invoke-Formatter` over the diff to ensure consistent code style before committing, and it snapshots file changes as git patches, allowing for easy diffing and rolling back of edits if needed. This robust review mechanism is integral to maintaining the integrity of your PowerShell projects.

Step by step

01Identify independent slices of your PowerShell repository for auditing, such as distinct module directories like `src/Modules/Utility` or specific file types like all `.psm1` files, using `glob` to define targets.
02Launch one `task` per slice, specifying `subagent_type explore` for a read-only sweep to prevent any modifications to your PowerShell scripts or module manifests. For example: `task 'Audit src/Modules/Utility for missing CmdletBinding' subagent_type explore`.
03Issue all `task` calls together in your Atlas session to ensure they run concurrently, leveraging parallel subagents to sweep your entire PowerShell codebase efficiently rather than sequentially.
04Collect each subagent's final message as it completes; Atlas will surface the child's conclusions or error text verbatim, or 'Task cancelled' if applicable, providing a summary of findings from your PowerShell audit.
05Merge the collected findings into a single `todowrite` list within your main Atlas session, consolidating all identified issues from the parallel PowerShell sweeps into an actionable plan.
06Use the `edit` tool in your main session to address the items on your `todowrite` list, such as adding `CmdletBinding` to a function in a `.psm1` file or resolving `PSScriptAnalyzer` warnings, reviewing each unified diff before approval.
07After edits, have Atlas run `Invoke-Formatter` over the diff to ensure consistent code style, and optionally `Invoke-Pester` on relevant `.Tests.ps1` files behind a permission prompt to verify fixes.
