# Document a Blazor Module with a README using Atlas in 2026 > Atlas ensures Blazor module READMEs are accurate and current by reading source code, verifying samples with `bash`, and integrating with `dotnet test (bUnit)`. In 2026, Atlas helps Blazor developers produce documentation that accurately describes what their code does today, not what it was supposed to do a year ago, by directly reading source files and verifying claims. It integrates with the Blazor toolchain, leveraging `dotnet test (bUnit)` for verification, `NuGet (dotnet add package)` for dependency management, and `dotnet format` for code style consistency, ensuring every detail is traceable and current. ## Key takeaways - Atlas generates Blazor READMEs directly from source, ensuring accuracy in 2026. - Every Blazor code sample in the documentation is verified with `bash` for functional correctness. - Atlas integrates with `dotnet test (bUnit)` for robust Blazor component validation. - Documentation reflects actual Blazor code behavior, not outdated specifications. - Atlas uses `lsp` to enumerate Blazor module APIs, preventing omissions. - All Blazor documentation changes are permission-gated and require diff approval. ## How Atlas documents Blazor modules with READMEs Atlas streamlines Blazor module documentation in 2026 by generating READMEs directly from source code, ensuring accuracy and relevance. It uses the `lsp` tool's `documentSymbol` operation to enumerate public APIs, guaranteeing no export is missed. This process ensures documentation reflects the actual code, not outdated specifications from 12 months ago. Atlas provides a robust workflow for documenting Blazor modules, focusing on generating READMEs that precisely reflect the current state of your codebase. Instead of relying on stale comments or developer memory, Atlas uses its `lsp` tool to perform a `documentSymbol` operation, enumerating every public API exported by your Blazor components, C# classes, and even JavaScript interop functions. This ensures 100% coverage of the module's surface area. Following this, the `read` tool delves into the implementation of each export, while `codebase_search` identifies how these exports are actually used in practice across your Blazor solution. This combination of direct source analysis and real-world usage context makes the generated documentation traceable and verifiable, rather than merely plausible. ## Blazor-specific commands and files for README generation Generating a Blazor module README with Atlas involves specific commands and file types, ensuring deep integration with your project. Atlas reads `.razor` components, `.csproj` files targeting the Blazor SDK, and even `IJSRuntime` interop calls. It then uses `grep` to match existing README structures, ensuring a consistent 1.0 tone and format. The documentation workflow within Atlas is deeply tailored to the Blazor ecosystem. When generating a README, Atlas first uses `grep` to scan your repository for any existing `README.md` files. This allows it to adopt your project's established heading structure, tone, and overall format, ensuring consistency. The content itself is derived from your Blazor-specific files: `.razor` components, their associated C# code-behind, and any C# files defining services or models. Atlas understands Blazor's unique constructs, such as `@rendermode` directives, cascading parameters, and `IJSRuntime` interop calls. When the documentation is drafted, the `write` tool emits the new `README.md`, quoting real C# signatures, actual `.razor` component paths, and concrete examples of `dotnet add package` commands for dependencies, making the documentation immediately recognizable and actionable for any Blazor developer. ## Ensuring Blazor code sample accuracy with `bash` and `dotnet test (bUnit)` Atlas verifies every Blazor code sample within your generated README using `bash`, preventing documentation drift and ensuring 100% accuracy. A sample that was never executed is a liability, so Atlas runs each snippet. For deeper validation, it can also prompt to add `bUnit` component tests and execute them via `dotnet test`. A critical aspect of reliable documentation is the accuracy of its code samples. Atlas addresses this directly by employing the `bash` tool to execute every single code snippet included in the generated Blazor README. This rigorous verification process ensures that all quoted code is not only syntactically correct but also functionally accurate in your current Blazor environment. A code sample that fails to execute is immediately flagged, preventing the documentation from becoming outdated or misleading. Furthermore, for Blazor components requiring more comprehensive validation, Atlas can prompt to generate and integrate `bUnit` component tests. These tests are then executed using the standard `dotnet test` command, providing a robust layer of behavioral verification that goes beyond simple execution, confirming the component's intended functionality within the Blazor rendering pipeline. ## Atlas's review and safety mechanisms for Blazor documentation Atlas incorporates multiple safety mechanisms to ensure Blazor documentation changes are transparent and approved. Every Atlas tool call is permission-gated, requiring explicit `allow`, `ask`, or `deny` rules before execution. The agent drafts a plan in a read-only agent, then computes a unified diff for every file edit, surfacing it for approval before writing to disk, offering 2 layers of review. Safety and developer control are paramount when Atlas modifies any part of your Blazor project, including documentation. Before any Atlas tool, such as `write` for the README, executes, it is subject to permission-gating, allowing you to configure `allow`, `ask`, or `deny` rules. This ensures that no action is taken without your explicit consent. The process begins with Atlas drafting a detailed plan in a read-only plan agent, outlining its proposed steps. Once a plan is approved, and before any file is actually modified, Atlas computes a unified diff for every proposed edit. This diff is then surfaced for your review and approval. For instance, when generating a `README.md` for a Blazor module, you will see the exact changes before they are written. Atlas also reads `git` branches, status, and diffs, and can snapshot file changes as `git` patches, allowing for easy rollbacks if needed, providing a secure and transparent documentation workflow. ## Steps 1. Initialize Atlas in your Blazor solution: Run `atlas` in a directory containing your `.razor` components and a `.csproj` targeting the Blazor SDK. 2. Enumerate public APIs: Atlas uses the `lsp` tool's `documentSymbol` operation to identify all exported members from your Blazor components and C# classes. 3. Read implementation and usage: Atlas employs the `read` tool to understand each export's behavior and `codebase_search` to find how it's actually used across your Blazor project. 4. Identify README structure: Atlas uses `grep` to locate any existing `README.md` files, learning the preferred heading structure and tone for your Blazor project. 5. Draft the Blazor module README: Atlas drafts the README content, quoting real C# signatures, `.razor` component paths, and `IJSRuntime` interop details. 6. Verify code samples: Atlas uses the `bash` tool to execute every code sample within the drafted README, ensuring they are 100% functional and reflect current Blazor behavior. 7. Approve and write the README: Atlas presents a unified diff of the new `README.md` for your approval. Once approved, the `write` tool commits the changes. 8. Optionally add and run `bUnit` tests: For critical Blazor components, Atlas can prompt to add `bUnit` component tests and run them using `dotnet test` to further validate behavior. ## FAQ ### How does Atlas ensure Blazor documentation is up-to-date?
