# Automate GitHub issue and pull request triage in Scala with Atlas in 2026 > Scala developers in 2026 can automate GitHub issue and pull request triage with Atlas, ensuring safe, AI-driven responses within their `sbt` projects. In 2026, Scala developers can automate GitHub issue and pull request triage safely and efficiently using Atlas, the terminal-native AI coding agent. Atlas integrates directly into GitHub workflows, leveraging your existing `sbt` project structure and respecting your `scalafmt` configurations to provide AI-driven responses and actions, ensuring only trusted users can trigger these operations. ## Key takeaways - Atlas automates GitHub issue and pull request triage specifically for Scala projects. - Security is paramount, with Atlas enforcing `admin` or `write` permissions and requiring explicit mentions. - Atlas deeply understands the Scala toolchain, including `sbt`, `scalafmt`, and `ScalaTest`. - All proposed changes to Scala code are presented as unified diffs for explicit developer approval. - Local Ollama embeddings ensure your Scala codebase remains private during indexing. - Atlas provides robust error handling for context overflow, listing problematic Scala files. ## How to Integrate Atlas for Scala GitHub Triage Automation In 2026, Scala developers can streamline GitHub issue and pull request triage by integrating the `atlas github` command directly into their workflows. This powerful entrypoint reads inputs from the GitHub Actions environment, requiring a `MODEL` in `provider/model` form and a `PROMPT` for specific event types, ensuring a robust and automated response system for Scala projects. Atlas provides a first-class GitHub entrypoint designed specifically for automating issue and pull request triage. For Scala projects, this means wiring the `atlas github` command into a GitHub Actions workflow, typically within a `.github/workflows/` directory. Atlas strictly validates its inputs: it requires a `MODEL` specified in `provider/model` format, such as `ollama/codellama`, and will refuse to run if this is incorrect. Furthermore, for event types that necessitate a response, a `PROMPT` input is mandatory; failure to provide one results in an explicit error message like "PROMPT input is required for events." This rigorous input validation ensures that Atlas operates predictably and safely within your Scala development environment, leveraging its ability to search code with hybrid semantic and keyword retrieval fused by reciprocal rank fusion, and indexing code by AST declarations using tree-sitter, which is particularly effective for understanding Scala's complex syntax and type system within your `build.sbt` managed project. ## Ensuring Secure and Trusted Scala Workflow Automation with Atlas Securing automated GitHub triage for Scala projects is paramount, and Atlas addresses this in 2026 by implementing stringent permission checks. Before any action is taken, Atlas verifies that the triggering actor possesses `admin` or `write` collaborator permissions, refusing to proceed for unauthorized users and ensuring only trusted individuals can initiate AI-driven responses. Atlas prioritizes security and trust in automated workflows for Scala developers. A critical safety mechanism is its upfront permission check: Atlas verifies the triggering actor's collaborator permission, refusing to run if the user lacks `admin` or `write` access. This prevents unauthorized individuals from initiating AI operations on your Scala codebase. Additionally, to prevent accidental or stray comments from triggering a run, the `atlas github` handler enforces that comments must explicitly mention the configured trigger. Every Atlas tool call, including `bash`, `read`, `grep`, and `edit`, is permission-gated against `allow`, `ask`, and `deny` rules before execution, providing granular control. For enhanced privacy, Atlas can build its code index with local Ollama embeddings, keeping your sensitive Scala code off third-party servers. This multi-layered security approach ensures that your automated triage system for Scala issues and pull requests remains safe, controlled, and compliant with your team's access policies. ## Concrete Scala Toolchain Integration and File Paths with Atlas Atlas deeply understands the Scala ecosystem in 2026, integrating direct with core tools like `sbt`, `scalafmt`, and `ScalaTest`. It operates within projects containing a `build.sbt` file, allowing it to read traits, implicits, and `sbt` modules, and even refactor code to typeclasses or add new `ScalaTest` cases. Atlas is engineered to be a native companion for Scala developers, recognizing and interacting with the specific toolchain. When operating within a Scala project, Atlas expects to find a `build.sbt` file, which it uses to understand the project structure, including `sbt` modules, traits, and implicits. This deep understanding allows Atlas to perform sophisticated tasks, such as refactoring existing Scala code to leverage typeclasses or generating new test cases using `ScalaTest via sbt test`. For maintaining code consistency, Atlas respects and can apply formatting rules defined by `scalafmt`. If Atlas needs to modify a file, it will use its `edit` tool, and any proposed changes will adhere to the project's `scalafmt` configuration. Should a GitHub event's context exceed the model's token limit, Atlas explicitly catches a `ContextOverflowError` and re-throws it as a user-friendly "prompt-too-large" message, listing the specific offending Scala files that contributed to the overflow, enabling developers to quickly identify and address the issue. ## Reviewing and Approving Atlas's Scala Code Changes In 2026, Atlas ensures full transparency and control over its automated actions on Scala codebases through a rigorous review process. Before any file is written, Atlas computes a unified diff for every proposed edit and surfaces it for explicit approval, allowing Scala developers to maintain oversight of all AI-generated changes. Atlas's design emphasizes human oversight, particularly crucial when automating changes to Scala code. When Atlas drafts a plan, it does so in a read-only plan agent, presenting its proposed strategy for review before switching to a build agent to execute changes. Crucially, for every file edit Atlas proposes, it computes a unified diff and surfaces it for explicit approval. This means Scala developers always see exactly what changes Atlas intends to make to their `.scala` files, `build.sbt`, or other project configurations before they are committed. Atlas also integrates deeply with Git, reading branches, status, and diffs, and can even stage and create commits on your behalf once changes are approved. To provide an additional layer of safety and rollback capability, Atlas snapshots file changes as git patches, ensuring that any edits can be easily diffed against previous states and rolled back if necessary. This comprehensive review and approval mechanism ensures that automated triage actions enhance, rather than compromise, the integrity of your Scala codebase. ## Steps 1. Configure GitHub Actions for Scala Triage: Create a `.github/workflows/atlas-triage.yml` file in your Scala project to define the workflow that will invoke the `atlas github` command for issue and pull request events. 2. Set Atlas Model and Prompt Inputs: Within your workflow, specify the `MODEL` input in `provider/model` format (e.g., `ollama/codellama`) and provide the `PROMPT` input for event types requiring it, ensuring Atlas has the necessary context for your Scala codebase. 3. Grant Trusted User Permissions: Ensure the GitHub actor triggering the workflow possesses `admin` or `write` collaborator permissions on your Scala repository, as Atlas will refuse to run for unauthorized users. 4. Require Explicit Mention for Activation: Configure the `atlas github` handler to enforce that comments must explicitly mention the configured trigger (e.g., `@atlas triage`) to initiate an automated response on Scala issues or pull requests. 5. Manage Context Overflow in Scala Projects: Be prepared to address `ContextOverflowError` by reviewing the specific Scala files listed in the "prompt-too-large" message, allowing you to refine the context provided to Atlas. 6. Review Atlas's Proposed Scala Changes: After Atlas drafts a plan, examine the unified diffs it generates for any proposed modifications to your `.scala` files or `build.sbt` before proceeding. 7. Approve or Reject Scala Code Edits: Explicitly approve Atlas's suggested changes to your Scala codebase, leveraging its ability to stage and create commits on your behalf, or reject them if they do not meet your standards. ## FAQ ### How does Atlas ensure my Scala code is secure when automating GitHub triage?
