Document a module with a README in PowerShell with Atlas in 2026

In 2026, Atlas empowers PowerShell developers to generate precise README documentation that reflects the current state of their modules, not outdated specifications. By integrating directly with the PowerShell toolchain, Atlas uses lsp to enumerate public APIs, read to understand implementation details, and bash to verify code samples, ensuring your documentation is always traceable and accurate. This approach guarantees that every claim in your README is backed by the actual code, providing a reliable resource for anyone using your PowerShell modules.

How Atlas Discovers PowerShell Module APIs for Documentation

Atlas precisely enumerates a PowerShell module's public API surface in 2026 using the lsp tool's documentSymbol operation. This ensures that every exported cmdlet, function, and variable defined within your .psm1 file is identified, preventing any omissions or fabrications in the generated README. The process guarantees a complete and accurate representation of your module's capabilities.

To generate documentation that truly reflects a PowerShell module's current state, Atlas begins by performing a comprehensive scan of the module's source files. It leverages the lsp tool's documentSymbol operation, which is specifically designed to understand the structure of code and identify all exported symbols. For a PowerShell module, this means Atlas can accurately list every cmdlet, advanced function, and variable that is publicly exposed through your .psm1 module file and declared in your .psd1 manifest. This method is superior to simple text parsing because it understands the Abstract Syntax Tree (AST) declarations, ensuring that only actual, callable exports are included. This foundational step guarantees that the README will cover the entire public API, providing a complete reference for users and other developers. Atlas's AST indexing, powered by tree-sitter, ensures this enumeration is robust and precise, even for complex PowerShell module structures.

Reading PowerShell Implementation and Usage with Atlas

Atlas reads the implementation of each PowerShell export and uses codebase_search to understand its practical application in 2026. This dual approach ensures the documentation describes not just what a function is supposed to do, but how it's actually used across your repository, providing a more accurate and context-rich README. This process is crucial for generating relevant examples.

After enumerating the public API, Atlas delves into the actual implementation of each PowerShell cmdlet or function. It uses the read tool to parse the source code, understanding param blocks, CmdletBinding attributes, and internal logic. To provide a truly accurate picture of the code's behavior, Atlas then employs codebase_search to find real-world examples of how these exports are called within your repository. This hybrid semantic and keyword retrieval, fused by reciprocal rank fusion, allows Atlas to identify common usage patterns, edge cases, and typical parameter values. For instance, if a function like Get-MyResource is frequently called with a specific -Filter parameter in your .\Scripts\Automation.ps1 files, Atlas will incorporate this practical context into the documentation. This ensures the README reflects the code's current operational reality, rather than just its theoretical design, making the documentation immediately useful for a PowerShell developer.

Drafting and Writing PowerShell READMEs with Atlas

Atlas drafts and writes the README for your PowerShell module using the write tool, ensuring consistency with existing documentation. It first grep's the repository for an existing README.md or docs\README.md to match its heading structure and tone, rather than inventing a new format. This approach ensures a cohesive documentation experience across your 2026 projects.

When it's time to generate the README, Atlas prioritizes consistency and accuracy. Before writing, it uses the grep tool to search for any existing README.md files within your project, such as .\README.md or .\docs\MyModule\README.md. This allows Atlas to adopt the established heading structure, tone, and formatting conventions, ensuring the new documentation integrates direct with your existing project standards. The write tool then constructs the README, quoting real PowerShell signatures directly from the source code and referencing real file paths. For example, it might include a code block like Get-MyModuleItem -Path 'C:\Data\item.json' with the exact parameter names and types. Atlas drafts a plan in a read-only plan agent, outlining the documentation structure and content, and asks for approval before switching to a build agent to execute the write operation. This permission-gated process ensures that the generated README aligns with your expectations and project guidelines.

Verifying PowerShell Code Samples for Accuracy

Atlas verifies every PowerShell code sample included in the generated README by running it with bash, ensuring 100% accuracy. A code sample that has never been executed is a significant liability, potentially misleading developers in 2026. This rigorous verification step guarantees that all examples provided in your documentation are functional and reflect the actual behavior of your PowerShell module.

A critical aspect of reliable documentation is the accuracy of its code samples. Atlas addresses this by executing every PowerShell code snippet it includes in the README. Using the bash tool, Atlas runs these samples in a controlled environment, treating any sample that fails to execute correctly as a documentation error. This proactive verification prevents the common problem of outdated or incorrect examples that can frustrate developers. For instance, if the README suggests Invoke-MyProcess -Force, Atlas will attempt to run this command, ensuring it executes without syntax errors or unexpected behavior. This process is permission-gated, meaning Atlas will ask for approval before running any commands, providing a crucial safety layer. By ensuring every example is runnable and produces the expected output, Atlas transforms documentation from a static description into a dynamic, verifiable resource for PowerShell developers.

Atlas's Safety and Review Mechanisms for PowerShell Documentation

Atlas incorporates multiple safety and review mechanisms when documenting PowerShell modules, ensuring every change is transparent and approved. Every Atlas tool call, including lsp or write, is permission-gated against allow, ask, and deny rules. Before writing any changes to your README.md file, Atlas computes a unified diff and surfaces it for your approval, providing 100% control over the output in 2026.

Atlas is designed with developer control and safety at its core, especially when modifying critical project files like README.md. Before any tool, such as lsp for API enumeration or write for generating content, is executed, Atlas checks against predefined permission rules (allow, ask, deny). This ensures that no action is taken without explicit or implicit consent. When Atlas proposes changes to your PowerShell module's documentation, it first drafts a plan in a read-only plan agent, detailing the steps it intends to take. Once approved, it switches to a build agent. Crucially, before writing any modifications to your README.md file, Atlas computes a unified diff, clearly showing every proposed addition, deletion, or change. This diff is then presented to you for approval, allowing you to review and accept or reject the changes. Atlas also snapshots file changes as git patches, so edits can be diffed and rolled back easily, providing a robust safety net for your PowerShell projects.
