How does Atlas ensure security for .NET GitHub triage workflows?

Atlas enforces security by checking that the triggering GitHub actor has `admin` or `write` permissions on the .NET repository. It also requires an explicit mention (e.g., `@atlas triage`) in comments to trigger a run, preventing accidental automation. All tool calls are permission-gated, and changes are presented as unified diffs for approval.

Can Atlas work with my existing ASP.NET Core project and its dependencies?

Yes, Atlas is designed to work with existing .NET projects, including ASP.NET Core. It reads `.sln` and `.csproj` files to understand your project structure, Minimal APIs, DI containers, and project references. It also interacts with `NuGet` for package management, ensuring compatibility with your existing dependencies.

What specific .NET tools does Atlas use for issue resolution and code changes?

Atlas leverages the actual .NET toolchain. It uses `dotnet test` for running `xUnit` tests, `NuGet` for package operations, and `dotnet format` for code formatting. Internally, it employs `bash`, `read`, `grep`, and `edit` tools to execute these commands and manipulate .NET source files effectively.

How does Atlas handle large .NET codebases or long prompts in a GitHub workflow?

Atlas explicitly handles context overflow. If a prompt or codebase context exceeds the model's capacity, it catches the `ContextOverflowError` and re-throws it as a 'prompt-too-large' message. This message lists the specific .NET files that contributed to the overflow, allowing developers to address the issue directly.

What kind of review process does Atlas offer for its changes to .NET code?

Atlas provides a robust review process. It drafts a plan in a read-only agent and asks for approval before execution. For every file edit, it computes and surfaces a unified diff for your review and approval. Additionally, Atlas snapshots file changes as git patches, enabling easy diffing and rollback of any modifications to your .NET codebase.

How do I trigger Atlas for a specific GitHub issue or PR in my .NET repository?

To trigger Atlas, you must configure your GitHub Actions workflow to listen for relevant events. Then, within a comment on an issue or pull request, you need to include the configured trigger mention, such as `@atlas triage`. Atlas will also verify that you have `admin` or `write` permissions on the .NET repository before proceeding.

Does Atlas support different models or providers for .NET triage tasks?

Yes, Atlas connects to Model Context Protocol servers and exposes their tools to the agent. You can switch the active model and provider on the fly with favorites and recents. For GitHub triage, the `atlas github` command requires the `MODEL` input to be in `provider/model` form (e.g., `ollama/llama3`), allowing flexibility in model choice.

Automate GitHub Issue and Pull Request Triage in .NET with Atlas in 2026

Atlas automates GitHub issue and pull request triage for .NET projects by integrating directly into GitHub Actions workflows, allowing it to respond to events safely and only for trusted users. It understands the .NET toolchain, interacting with `NuGet` for package management, `dotnet test` for `xUnit` execution, and `dotnet format` for code consistency, ensuring changes are relevant and adhere to project standards.

How Atlas Automates GitHub Triage for .NET Projects

Atlas streamlines GitHub issue and pull request triage for .NET projects by providing a first-class GitHub entrypoint, the `atlas github` command, which is designed to operate within GitHub Actions. This command rigorously checks its inputs, such as the `MODEL` in `provider/model` form, and refuses to run if they are incorrect, ensuring reliable automation in 2026.

The `atlas github` command is the core of automating triage for your .NET codebase. It's engineered to read its necessary inputs directly from the GitHub Actions environment, ensuring a robust and predictable execution. For instance, it requires the `MODEL` input to be specified in the `provider/model` format (e.g., `ollama/llama3`), and if this or other critical inputs are missing or malformed, Atlas will explicitly refuse to run, preventing misconfigurations. This direct integration means that Atlas can be wired into your existing GitHub workflows, allowing it to monitor and respond to issue and pull request events for your ASP.NET Core web APIs and services. Atlas is designed to work within a .NET solution, recognizing `.sln` or `.csproj` files to build its understanding of your project structure, including Minimal APIs, DI containers, and project references.

Configuring Atlas for Secure .NET Triage Workflows

Securing automated triage is paramount, and Atlas enforces strict controls to ensure only trusted users can trigger its operations on your .NET repositories. In 2026, Atlas checks the triggering actor's GitHub collaborator permissions, requiring either `admin` or `write` access before it proceeds, preventing unauthorized runs.

Atlas implements several non-negotiable security checks to ensure that automated triage actions are performed safely and under explicit control. First, it verifies the permissions of the GitHub actor who triggered the workflow. Atlas will refuse to execute if the actor does not possess `admin` or `write` permissions on the repository, safeguarding against unauthorized modifications. Second, to prevent accidental or stray comments from initiating a run, the `atlas github` handler enforces that comments must explicitly mention the configured trigger (e.g., `@atlas triage`). This 'mention-to-trigger' mechanism provides an additional layer of control. Furthermore, Atlas explicitly handles context overflow scenarios. If a prompt becomes too large for the configured model, a `ContextOverflowError` is caught by name and re-thrown as a user-friendly 'prompt-too-large' message, listing the specific offending files in your .NET codebase that contributed to the overflow, allowing for explicit resolution rather than silent failure.

Atlas's Interaction with the .NET Toolchain

Atlas is deeply integrated with the .NET ecosystem, understanding and utilizing its native toolchain to perform tasks. When working with your .NET projects in 2026, Atlas can invoke `xUnit via dotnet test` for verification, manage dependencies with `NuGet`, and ensure code style with `dotnet format`, making it a true .NET-native agent.

Atlas is not just a generic AI agent; it's specifically designed to understand and interact with the .NET development environment. It builds its code index by parsing AST declarations using tree-sitter, allowing it to comprehend the structure of your .NET code, including ASP.NET Core Minimal APIs, dependency injection configurations, and project references within `.sln` and `.csproj` files. This deep understanding enables Atlas to perform concrete actions, such as adding a new endpoint to an ASP.NET Core application or generating an `xUnit` test case. When it needs to verify changes, Atlas will use `dotnet test` to run your `xUnit` tests. For package management, it understands `NuGet` operations, and for maintaining code consistency, it can apply `dotnet format`. The agent leverages its internal tools like `bash`, `read`, `grep`, and `edit` to execute these .NET-specific commands and manipulate files, ensuring that its proposed changes are syntactically correct and functionally sound within your .NET project.

Ensuring Safety and Review for Atlas-Generated .NET Changes

Atlas prioritizes safety and transparency in every change it proposes to your .NET codebase, employing a multi-stage approval process. Every tool call is permission-gated, and all file edits are presented as a unified diff for your explicit approval before being written, ensuring you maintain full control over your project in 2026.

The safety mechanisms within Atlas are designed to give .NET developers complete confidence and control over automated changes. Before any Atlas tool call (such as `edit` or `bash`) is executed, it is permission-gated against `allow`, `ask`, and `deny` rules, ensuring that the agent only performs actions you've explicitly permitted. Atlas operates with a read-only plan agent that drafts a comprehensive plan of action, which it then presents for your review and approval before switching to a build agent to execute the plan. Crucially, for every file edit Atlas proposes, it computes a unified diff and surfaces it for your approval. This allows you to meticulously review every line change before it's committed to your .NET project. Furthermore, Atlas snapshots file changes as git patches, providing a robust mechanism to diff edits and roll back any changes if necessary. This comprehensive review and rollback capability ensures that even automated triage actions are fully auditable and reversible, maintaining the integrity of your .NET codebase.

Step by step

01Create a GitHub Actions workflow file (e.g., `.github/workflows/atlas-triage.yml`) in your .NET repository.
02Wire the `atlas github` command into your workflow, setting the `MODEL` input (e.g., `MODEL: 'ollama/llama3'`) and providing the `PROMPT` input for relevant event types, as Atlas rejects runs with incorrect inputs.
03Ensure the GitHub workflow is configured to run only when the triggering actor has `admin` or `write` collaborator permissions on the .NET repository, as Atlas enforces this security check.
04Configure the `atlas github` handler to enforce a mention trigger (e.g., `@atlas triage`) in comments, preventing stray comments from initiating a run on your .NET issues or pull requests.
05Atlas will then read your .NET solution's `.sln` or `.csproj` files, indexing your code by AST declarations to understand Minimal APIs, DI containers, and project references.
06Atlas drafts a plan in its read-only plan agent, potentially proposing changes like adding an `xUnit` test or modifying an ASP.NET Core endpoint, using tools like `grep` and `edit`.
07Review the unified diff presented by Atlas for any proposed changes to your .NET files, approving them before Atlas writes the changes and potentially runs `dotnet build`.
08Atlas can stage and create commits on your behalf, capturing changes as git patches for easy diffing and rollback, ensuring full control over your .NET project history.
