How does Atlas ensure my Dart code is safe from unwanted changes during triage?

Atlas ensures safety through multiple layers: it verifies the triggering user has `admin` or `write` permissions, requires explicit mentions to run, drafts plans in a read-only agent, permission-gates all tool calls, and presents a unified diff for every proposed change to Dart files for your explicit approval before writing. It also snapshots changes as `git` patches for rollback.

Can Atlas handle large Dart codebases without context overflow?

Yes, Atlas is designed to handle context overflow explicitly. It catches `ContextOverflowError` by name and re-throws it as a prompt-too-large message, listing the specific Dart files that caused the overflow, allowing you to address the issue directly.

How do I restrict Atlas to only trusted users in my Dart GitHub workflow?

Atlas automatically enforces this restriction. The `atlas github` command checks the triggering actor's collaborator permission and will refuse to run if the user does not have `admin` or `write` access to the Dart repository, ensuring only trusted users can initiate automated triage.

Does Atlas integrate with `pub` for dependency management in Dart projects?

Yes, Atlas integrates directly with `pub`. It reads your `pubspec.yaml` to understand existing `pub` dependencies and can suggest or implement changes to your dependencies as part of a triage task, such as adding a new package or updating an existing one, always presenting changes for your review.

How does Atlas's TUI help me review changes to Dart files?

Atlas's terminal-native TUI, rendered with SolidJS, provides a clear interface for reviewing changes. It presents a unified diff for every proposed edit to your Dart files, allowing you to see line-by-line modifications in a charcoal-and-blue default theme or other presets, making the review process transparent and user-friendly.

Can Atlas help migrate my Dart project to null safety?

Yes, Atlas can assist with migrating your Dart project to null safety. By understanding your Dart code through AST declarations and reading your `analysis_options.yaml`, you can ask Atlas to propose changes for null safety migration, reviewing the generated diffs before applying them to your Dart files.

Automate GitHub issue and pull request triage in Dart with Atlas in 2026

In 2026, Dart developers can automate GitHub issue and pull request triage using Atlas, the terminal-native AI coding agent, by wiring the `atlas github` command into a GitHub Actions workflow, ensuring safe, permission-gated responses for trusted users within their `pub` managed projects.

How does Atlas automate GitHub issue triage for Dart projects?

Atlas automates GitHub issue and pull request triage for Dart projects by integrating the `atlas github` command directly into a GitHub Actions workflow. This command, available in 2026, reads its inputs from the Actions environment, requiring a `MODEL` in `provider/model` form and a `PROMPT` for specific event types, ensuring a robust and automated response system.

For Dart developers, Atlas provides a first-class GitHub entrypoint designed to streamline operations within their repositories. When `atlas github` is invoked from a GitHub workflow, it rigorously validates its environment. It explicitly requires the `MODEL` input, specified as `provider/model` (e.g., `ollama/llama3`), and will refuse to run if this is missing or malformed. Similarly, for event types that necessitate a prompt, the `PROMPT` input must be provided; otherwise, the handler fails with a clear `PROMPT input is required for <event> events` message. This strict input validation ensures that Atlas operates predictably and only under explicitly defined conditions. Atlas is designed to work direct within a Dart package structure, reading your `pubspec.yaml` file, understanding your `pub` dependencies, and respecting your `analysis_options.yaml` to provide contextually relevant responses. For instance, if a pull request modifies a Dart file, Atlas can analyze the changes, suggest improvements, or even draft tests using `dart test` based on the provided prompt, all while understanding the nuances of null-safe Dart code.

How does Atlas ensure safety and trust in Dart GitHub workflows?

Atlas ensures safety and trust in Dart GitHub workflows by implementing stringent permission checks and explicit user approval mechanisms. In 2026, Atlas verifies that the triggering actor possesses `admin` or `write` permissions before executing any actions, preventing unauthorized automation and protecting your Dart codebase from unintended modifications.

Security is paramount when automating actions on a Dart codebase. Atlas enforces strict access controls: it checks the triggering actor's collaborator permission and refuses to run for anyone without `admin` or `write` access to the repository. This prevents unauthorized users from initiating automated triage. Furthermore, to avoid accidental runs, the `atlas github` handler enforces that comments must explicitly mention the configured trigger (e.g., `@atlas triage`) to start a run. Internally, Atlas employs a multi-stage safety protocol. It first drafts a plan in a read-only plan agent, which then asks for approval before switching to a build agent that can make changes. Every tool call, including `bash`, `read`, `grep`, and `edit`, is permission-gated against `allow`, `ask`, and `deny` rules. For any proposed changes to Dart files, Atlas computes a unified diff and surfaces it for explicit approval before writing to disk. It also snapshots file changes as git patches, allowing edits to be diffed and rolled back if necessary, providing a robust safety net for your Dart project.

How does Atlas integrate with Dart's toolchain for automated triage?

Atlas integrates deeply with Dart's toolchain, recognizing and utilizing core Dart commands and file structures for automated triage. It operates within any Dart package containing a `pubspec.yaml` file, allowing it to understand `pub` dependencies, analysis options, and even assist with tasks like migrating to null safety in 2026.

Atlas is designed to be a native companion for Dart developers. When run in a Dart package, it automatically reads and understands the project's `pubspec.yaml` file, which is crucial for managing `pub` dependencies. This allows Atlas to comprehend the project's structure, available libraries, and declared dependencies. It also processes `analysis_options.yaml` to align with your project's linting and analysis rules. This deep understanding enables Atlas to perform context-aware actions, such as suggesting fixes that adhere to your project's style or adding new `pub` dependencies if required by a triage task. For example, if a pull request introduces a bug, Atlas can use its `grep` and `read` tools to locate relevant Dart files, then use `edit` to propose a fix, ensuring the changes are consistent with the project's existing code. It can even be asked to add tests using `dart test` for new features or bug fixes, reviewing the generated diff before committing. Atlas's ability to index code by AST declarations using tree-sitter, rather than blind line windows, means it understands the semantic structure of Dart code, making its suggestions and modifications highly accurate and relevant to the Dart language.

How do I review and approve Atlas's changes to Dart code?

Reviewing and approving Atlas's changes to Dart code is a transparent, user-driven process, ensuring full control over your project. Atlas computes a unified diff for every file edit, presenting it for explicit approval before writing, and can stage and create commits on your behalf, making the process clear and auditable in 2026.

Atlas prioritizes developer control and transparency, especially when making modifications to Dart code. Before any changes are written to your local Dart files, Atlas computes a unified diff for every proposed edit. This diff is surfaced to the user for explicit approval, allowing you to review exactly what Atlas intends to change. This is critical for maintaining code quality and ensuring that automated triage actions align with your project's standards. For instance, if Atlas suggests modifying a Dart file like `lib/src/my_feature.dart` or updating a `pubspec.yaml` dependency, you will see the exact line-by-line changes before they are applied. Atlas also reads `git` branches, status, and diffs, and can stage and create commits on your behalf, integrating direct into your existing Git workflow. It snapshots file changes as `git` patches, providing a robust mechanism for diffing and rolling back edits if needed. This granular control, combined with Atlas's TUI theme system (featuring a charcoal-and-blue default and many presets), provides a clear and comfortable environment for reviewing and approving automated changes to your Dart codebase, ensuring that every modification is intentional and verified.

Step by step

01Initialize a Dart project: Create a new Dart project or navigate to an existing one containing a `pubspec.yaml` file. Ensure `pub get` has been run to resolve dependencies.
02Configure GitHub Actions workflow: Create a `.github/workflows/atlas_triage.yaml` file in your Dart repository.
03Wire `atlas github` command: Within `atlas_triage.yaml`, add a step to call `atlas github`, providing the `MODEL` input (e.g., `ollama/llama3`) and the `PROMPT` input for relevant event types.
04Restrict workflow triggers: Configure the workflow to check the triggering actor's permissions, ensuring Atlas only runs if the user has `admin` or `write` access to the Dart repository.
05Enforce mention requirement: Set up the `atlas github` handler to require an explicit mention (e.g., `@atlas triage`) in comments to trigger a run, preventing accidental automation.
06Handle context overflow: Implement explicit error handling in your workflow for `ContextOverflowError`, re-throwing it as a prompt-too-large message that lists offending Dart files.
07Review Atlas's proposed Dart changes: When Atlas suggests modifications to Dart files (e.g., `lib/main.dart`, `test/widget_test.dart`), review the unified diff presented by Atlas in its terminal-native TUI.
08Approve and commit changes: Approve Atlas's proposed changes, allowing it to write to your Dart files and then stage and create a `git` commit on your behalf, integrating directly into your version control.
