How do I audit a large Blazor codebase without hitting context limits?

Atlas uses parallel subagents to sweep large Blazor repositories. Each subagent operates in its own session, keeping its file dumps out of the main context window, and only its conclusions return, effectively bypassing context limits.

Can Atlas modify my Blazor code during an audit?

When using the `explore` subagent for an audit, Atlas operates in a read-only mode. All tool calls are permission-gated, and any potential changes would require explicit approval of a unified diff in the main session, ensuring no accidental modifications to your Blazor code.

How does Atlas handle Blazor-specific files like .razor components?

Atlas indexes Blazor code by AST declarations using tree-sitter, understanding `.razor` components, `@rendermode` directives, cascading parameters, and `IJSRuntime` interop calls, ensuring a Blazor-aware and precise audit.

What Blazor tools does Atlas integrate with for auditing?

Atlas integrates directly with the Blazor toolchain, including `dotnet test (bUnit)` for running component tests, `NuGet (dotnet add package)` for package management, and `dotnet format` for consistent code formatting.

How do I split an audit task for parallel execution in a Blazor project?

Split Blazor audit tasks by logical slices such as specific directories containing `.razor` components (e.g., `Pages/`, `Shared/`), individual `NuGet` packages referenced in `.csproj` files, or specific coding rule checks across the codebase.

What happens if a subagent finds an issue in my Blazor code?

If a subagent finds an issue, its conclusion is returned to the main Atlas session. You can then use the `todowrite` tool to consolidate findings and the `edit` tool to apply fixes, followed by `dotnet format` and `dotnet test (bUnit)` to verify.

Does Atlas support local embeddings for Blazor code?

Yes, Atlas can build its code index with local Ollama embeddings, ensuring your Blazor code remains off third-party servers during the audit process, maintaining data privacy and security.

How does Atlas ensure code quality after fixes in Blazor?

After applying fixes with `edit`, Atlas prompts you to run `dotnet format` for style consistency and `dotnet test (bUnit)` to validate that component tests pass, ensuring high code quality in your Blazor project.

Audit a Blazor Repo with Parallel Subagents in Atlas, 2026

To sweep an entire Blazor repository for a class of problems without blowing the main session's context window, Atlas leverages parallel subagents that run read-only `explore` tasks. This approach allows you to audit .razor components and C# code, integrating with `dotnet test (bUnit)`, `NuGet (dotnet add package)`, and `dotnet format` for a comprehensive review in 2026.

How Atlas Audits Blazor Repositories with Parallel Subagents

Atlas audits Blazor repositories by fanning out work to multiple subagents, preventing the main session's context window from overflowing. In 2026, this capability is crucial for sweeping large codebases with thousands of .razor components and C# files, as only the subagents' conclusions return to the main session.

Atlas is designed to tackle the challenge of auditing extensive Blazor codebases without overwhelming the primary agent's context window. It achieves this by utilizing the `task` tool to launch multiple subagents, which can run in parallel background sessions. For auditing, the `explore` subagent type is ideal because it is deny-by-default and read-only, ensuring no unintended modifications occur during the sweep. Each subagent operates in its own isolated environment, processing a specific slice of the Blazor repository. This means that the voluminous file dumps and intermediate processing steps generated by each subagent never enter your main session's context. Instead, only the concise, actionable conclusions from each subagent are surfaced back to the main Atlas session, making it highly efficient for reviewing .razor components, C# code, and even complex `IJSRuntime` interop calls across a large Blazor solution.

Structuring Blazor Audit Slices for Parallel Execution

To effectively audit a Blazor repository, split the task into independent slices, ensuring subagents do not overlap. This strategy allows 5 or more subagents to concurrently examine distinct parts of your codebase, such as specific directories containing .razor components or individual NuGet packages.

The efficiency of a parallel audit in Atlas hinges on how effectively you split the Blazor repository into independent slices. For Blazor projects, this can involve segmenting the codebase by logical units. You might divide the audit by directory, assigning subagents to sweep specific folders like `Pages/`, `Shared/`, or `Components/` where `.razor` files reside. Alternatively, you could slice the audit by `NuGet` package dependencies, instructing subagents to examine code related to specific `PackageReference` entries within your `.csproj` files. Another effective method is to split by a class of problem or a specific rule, such as 'find all unhandled exceptions in `InteractiveServer` components' or 'identify all `IJSRuntime` calls lacking proper error handling.' The `glob` tool within Atlas can assist in defining these precise file sets for each subagent, ensuring that each task is self-contained and that subagents do not duplicate effort or interfere with each other's scope.

Launching and Monitoring Parallel Blazor Audit Tasks

Launching parallel audit tasks in Atlas involves issuing multiple `task` calls together, allowing them to run concurrently rather than sequentially. This approach can reduce the total audit time by 50% or more, as subagents independently process their assigned Blazor code slices.

Once your Blazor repository is logically sliced, launching the parallel audit is straightforward using Atlas's `task` tool. You issue multiple `task` calls in quick succession, specifying `subagent_type explore` for each to ensure a read-only sweep. For example, you might launch one task to audit `Pages/**/*.razor` for accessibility issues and another to audit `Services/**/*.cs` for potential null reference exceptions. Atlas then fans out these tasks to subagents, which execute concurrently. During execution, Atlas provides real-time feedback, surfacing each subagent's final message. If a subagent encounters an issue or fails to complete its task, Atlas will surface the child's error text verbatim. If a task is manually stopped, it will report 'Task cancelled.' This transparent monitoring allows you to track the progress of your Blazor audit across all parallel sessions and quickly identify any subagents that require attention, without ever needing to dive into their individual context windows.

Consolidating and Resolving Blazor Audit Findings

After parallel subagents complete their Blazor repository sweeps, Atlas helps consolidate their findings into a unified `todowrite` list. This list, which might contain 10 or more distinct issues, then guides fixes in the main session using the `edit` tool, followed by `dotnet format` and `dotnet test (bUnit)`.

Upon the completion of all parallel subagent tasks, Atlas facilitates the consolidation of their individual findings. Each subagent's conclusions, which might highlight issues in `.razor` components, C# code, or `csproj` configurations, are gathered. You can then use the `todowrite` tool to merge these findings into a single, actionable list within your main Atlas session. This centralized list serves as your roadmap for remediation. For each identified issue, you can leverage the `edit` tool to make precise changes directly within your Blazor codebase. After applying fixes, Atlas encourages best practices by prompting you to run `dotnet format` to maintain code style consistency and `dotnet test (bUnit)` to verify that your changes have not introduced regressions and that component tests pass. Atlas also computes a unified diff for every file edit, which is surfaced for your approval before any changes are written to disk, providing an additional layer of safety and control.

Ensuring Safety and Permissions in Blazor Audits

Atlas prioritizes safety during Blazor repository audits by using the `explore` subagent, which is deny-by-default and read-only. This ensures that 0 unintended changes occur during the sweep, as every Atlas tool call is permission-gated against allow, ask, and deny rules before execution.

Safety is paramount when sweeping an entire Blazor repository, and Atlas is built with robust safeguards. When conducting an audit, the recommended `explore` subagent type is inherently read-only and operates under a deny-by-default policy. This means that it cannot execute commands that would modify your Blazor codebase, such as altering `.razor` files, C# source, or `csproj` configurations, without explicit intervention. Furthermore, every single Atlas tool call, whether from the main agent or a subagent, is permission-gated. Before any action runs, it is checked against your predefined allow, ask, and deny rules. Atlas also drafts a plan in a read-only plan agent and asks for your approval before switching to a build agent that could make changes. Even then, any proposed file edits are presented as a unified diff for your final approval, and Atlas snapshots file changes as git patches, allowing edits to be diffed and rolled back if necessary. This multi-layered security ensures that your Blazor audit is thorough yet completely safe.

Step by step

01Ensure Atlas is running within your Blazor solution's directory, containing `.razor` components and a `.csproj` targeting the Blazor SDK.
02Identify independent slices of your Blazor repository for audit, such as specific component directories (e.g., `Pages/`, `Shared/`) or `NuGet` package contexts.
03Launch parallel audit tasks for each slice using the `task` tool, specifying `subagent_type explore` for a read-only sweep (e.g., `task 'audit Pages/**/*.razor for X' subagent_type explore`).
04Monitor the concurrent subagent tasks and collect their final messages, noting any reported errors or conclusions.
05Merge the findings from all subagents into a unified `todowrite` list in your main Atlas session.
06Address each identified issue in the Blazor codebase using the `edit` tool, making precise changes to `.razor` components or C# files.
07Apply Blazor code formatting standards by running `dotnet format` to ensure consistency.
08Verify the fixes and overall code health by executing Blazor component tests with `dotnet test (bUnit)`.
09Review the unified diff of all changes presented by Atlas and approve them to write to your Blazor project.
10Utilize Atlas to stage and create a git commit for the approved Blazor code changes.
