Can Atlas manage Deno dependencies via JSR or npm?

Yes, Atlas integrates direct with Deno's dependency management. It can read your project's `deno.json` or `deno.jsonc` file to understand existing JSR and npm specifiers. Furthermore, Atlas can add new dependencies using the `deno add jsr:@std/...` command, automatically updating your configuration without manual intervention, just as a Deno developer would expect.

What Deno code quality tools does Atlas integrate with?

Atlas integrates with Deno's native code quality tools. It can run `deno test` and `deno check` to validate code correctness and type safety, prompting for permission before execution. For code style and consistency, Atlas can apply `deno fmt` and `deno lint` to the unified diffs of any changes it proposes, ensuring your Deno codebase adheres to your project's standards.

How does Atlas handle large Deno pull requests or issues that might exceed model context limits?

Atlas explicitly handles context overflow by catching `ContextOverflowError`. When a Deno pull request or issue's content is too large for the AI model, Atlas re-throws this error as a clear message. This message informs the user that the prompt is too large and lists the specific files or sections causing the overflow, providing actionable feedback rather than a silent failure.

Does Atlas keep my Deno code private when indexing?

Yes, Atlas offers options to maintain code privacy. It indexes Deno code by AST declarations using tree-sitter for precise understanding. Crucially, Atlas can build its code index with local Ollama embeddings, which means your Deno source code remains on your local infrastructure and is not sent to third-party servers for embedding generation, enhancing data security.

How does Atlas ensure its actions are reviewed before writing to my Deno project?

Atlas employs a multi-stage review process. It first drafts a plan in a read-only plan agent and asks for approval before switching to a build agent. For every file edit, Atlas computes a unified diff and surfaces it for your approval before writing. Additionally, it snapshots file changes as git patches, allowing edits to be easily diffed and rolled back, providing full control over automated changes in your Deno project.

Automate GitHub Issue and Pull Request Triage in Deno with Atlas in 2026

Atlas empowers Deno developers to automate GitHub issue and pull request triage directly from a GitHub workflow, leveraging Deno's robust permission flags and integrated toolchain. By wiring the `atlas github` command into your CI/CD, you can ensure that Atlas responds safely and only for trusted users, integrating direct with `deno test`, `deno add (JSR)`, and `deno fmt` for a truly native experience.

How Atlas Automates GitHub Triage in Deno Workflows

Atlas provides a first-class GitHub entrypoint to automate issue and pull request triage within your Deno projects, ensuring secure operations by 2026. This entrypoint reads its inputs directly from the GitHub Actions environment, refusing to run if critical parameters like the MODEL or PROMPT are incorrect or missing.

Integrating Atlas into your Deno project's GitHub workflow allows for intelligent, automated responses to issues and pull requests. The `atlas github` command is specifically designed to operate within the GitHub Actions environment. It rigorously validates inputs, requiring a `MODEL` in `provider/model` form and a `PROMPT` for specific event types. This upfront validation prevents misconfigurations and ensures that the agent only proceeds when all necessary information is correctly supplied. For Deno developers, this means a predictable and secure automation layer that respects the same principles of explicit permissions and configuration that are central to the Deno runtime itself. Atlas's ability to index code by AST declarations using tree-sitter, rather than blind line windows, ensures a deep understanding of your Deno codebase, allowing for more accurate and context-aware triage actions.

Securely Triggering Atlas for Deno Projects

To maintain security, Atlas enforces strict permission checks, requiring the triggering actor to possess at least admin or write permissions before executing any triage actions. This ensures that only trusted collaborators can initiate automated responses, a critical safeguard in any Deno project's CI/CD pipeline by 2026.

Atlas prioritizes security by implementing robust checks on who can trigger its GitHub workflow actions. Before any operation, Atlas verifies the actor's collaborator permission, refusing to run for anyone without `admin` or `write` access. This prevents unauthorized automation and maintains the integrity of your Deno repository. Furthermore, the handler enforces that comments must explicitly mention the configured trigger, preventing stray comments from accidentally starting a run. This dual layer of security,permission checks and explicit mentions,aligns perfectly with Deno's own philosophy of explicit permissions, providing Deno developers with confidence that their automated triage system is both powerful and safe. Atlas's permission-gated tool calls, including `bash`, `read`, `grep`, and `edit`, further reinforce this secure execution model.

Handling Context Overflow in Deno Triage with Atlas

Atlas explicitly handles context overflow during triage, catching `ContextOverflowError` by name and re-throwing it as a user-friendly message listing offending files. This proactive approach ensures that even large Deno pull requests or issues can be managed effectively without silent failures in 2026.

When dealing with complex Deno issues or pull requests that involve extensive code changes or lengthy discussions, the potential for context overflow in AI models is a real concern. Atlas addresses this head-on by explicitly catching `ContextOverflowError`. Instead of silently failing or producing truncated responses, Atlas re-throws this error as a clear, actionable message. This message informs the user that the prompt is too large and precisely lists the files or sections that are causing the overflow. This transparency is invaluable for Deno developers, allowing them to understand why an automated triage action might not have completed and to adjust their approach accordingly. It ensures that even in scenarios with significant code context, Atlas provides useful feedback, maintaining the reliability of your automated workflow.

Deno Toolchain Integration and Atlas's Code Indexing

Atlas integrates deeply with the Deno toolchain, recognizing `deno.json` or `deno.jsonc` files to understand your project's structure and dependencies. This allows Atlas to build its code index using local Ollama embeddings, keeping your Deno code off third-party servers in 2026.

For Deno developers, Atlas offers a truly native experience by understanding and interacting with the Deno toolchain. When run in a project containing a `deno.json` or `deno.jsonc` file, Atlas automatically reads your imports map, JSR and npm specifiers, and the tasks defined within your configuration. This deep integration enables Atlas to perform intelligent code analysis and modifications. For instance, Atlas can tighten broad `--allow-all` tasks down to specific `--allow-net` and `--allow-read` scopes, enhancing security. It can also add dependencies using `deno add jsr:@std/...` directly, rather than requiring manual `import_map.json` edits. Atlas builds its code index by AST declarations using tree-sitter, ensuring a precise understanding of your Deno code, and can even use local Ollama embeddings to keep your proprietary code off third-party servers, a significant privacy advantage.

Automated Code Review and Formatting with Deno and Atlas

Atlas can automate code review tasks in Deno, running `deno test` and `deno check` behind a permission prompt, then applying `deno fmt` and `deno lint` to the generated diff. This ensures consistent code quality and style across your Deno codebase by 2026.

Beyond triage, Atlas extends its capabilities to automated code review and formatting within Deno projects. It can be configured to run `deno test` and `deno check` on proposed changes, providing immediate feedback on correctness and type safety. Crucially, these operations are executed behind a permission prompt, giving developers explicit control over potentially impactful actions. After any modifications or for general code hygiene, Atlas can then apply `deno fmt` and `deno lint` to the unified diff it computes for every file edit. This ensures that all code adheres to your project's defined style and best practices, reducing manual review effort and maintaining a high standard of code quality. The ability to snapshot file changes as git patches also means that any edits made by Atlas can be easily diffed and rolled back, providing a safety net for automated refactoring.

Step by step

01Configure your Deno project with a `deno.json` or `deno.jsonc` file, ensuring Atlas can read your imports map and tasks.
02Create a GitHub Actions workflow (e.g., `.github/workflows/triage.yml`) and wire the `atlas github` command into it.
03Set the `MODEL` input in `provider/model` format (e.g., `MODEL: 'ollama/llama3'`) for the `atlas github` command.
04Provide the `PROMPT` input for specific event types that require it, ensuring Atlas has clear instructions for triage.
05Ensure the GitHub workflow is configured to run only for trusted users by leveraging Atlas's built-in check for `admin` or `write` collaborator permissions.
06Configure the workflow to require a mention (e.g., `@atlas triage`) in comments to trigger a run, preventing accidental automation.
07Allow Atlas to run `deno test` and `deno check` behind a permission prompt, then `deno fmt` and `deno lint` on generated diffs for automated code quality.
08Let Atlas add Deno dependencies using `deno add jsr:@std/...` directly, updating your `deno.json` or `deno.jsonc` automatically.
