# Automate GitHub Issue and Pull Request Triage in Perl with Atlas in 2026

> Perl developers can automate GitHub issue and pull request triage safely in 2026 using Atlas, integrating with `cpanm` and `prove (Test2::V0)` for robust workflow automation.

In 2026, Perl developers can automate GitHub issue and pull request triage directly from a GitHub workflow using Atlas, the terminal-native AI coding agent. Atlas integrates with your existing Perl toolchain, leveraging `cpanm` for dependencies, `prove (Test2::V0)` for testing, and `perltidy` for consistent code formatting, ensuring safe and trusted automation.

## Key takeaways

- Atlas automates GitHub triage for Perl projects via the `atlas github` command in workflows.
- Security is enforced with `admin` or `write` permissions and explicit mentions for Perl repository interactions.
- Context overflow in Perl issues is handled gracefully, listing specific files that exceed model limits.
- Atlas understands and integrates with Perl's `cpanm`, `prove (Test2::V0)`, and `perltidy` toolchain.
- All Atlas tool calls, including `bash` and `edit` operations on Perl files, are permission-gated for safety.

## How Atlas Automates GitHub Triage for Perl Codebases

Atlas provides a first-class `atlas github` command to automate issue and pull request triage for Perl projects, ensuring safe operation by refusing to run without correct inputs. This command requires a `MODEL` in `provider/model` form and a `PROMPT` for specific event types, preventing 0 runs from misconfiguration.

Atlas streamlines GitHub triage for Perl repositories by integrating directly into your GitHub Actions workflows. The `atlas github` command is designed to be robust, validating its inputs from the Actions environment. It explicitly requires the `MODEL` environment variable, specified as `provider/model` (e.g., `ollama/codellama`), and a `PROMPT` input for any event types that demand one. If these critical inputs are missing or malformed, Atlas will reject the run upfront, preventing unintended or incomplete automation. This ensures that your Perl codebase's issues and pull requests are handled only when all necessary AI context and instructions are correctly provided. Atlas uses its core capabilities, like searching code with hybrid semantic and keyword retrieval, to understand the Perl context, indexing code by AST declarations using tree-sitter for precise analysis of `.pm` modules and `cpanfile` dependencies.

## Securing Automated Triage for Perl Projects

Securing automated triage for Perl projects is paramount, and Atlas enforces strict permission checks, refusing to run for any actor without `admin` or `write` collaborator permissions. This ensures that only 1 trusted user can trigger automated responses, preventing unauthorized agent activity on your repository.

Atlas prioritizes security for automated GitHub triage in Perl projects. Before executing any actions, the `atlas github` handler rigorously checks the triggering actor's collaborator permissions. It will explicitly refuse to run if the actor does not possess `admin` or `write` access to the repository. This critical safeguard ensures that only trusted team members can initiate automated responses to issues and pull requests. Furthermore, to prevent accidental or stray comments from triggering the agent, Atlas enforces that comments must explicitly mention the configured trigger (e.g., `@atlas triage`). This dual-layer security mechanism ensures that your Perl codebase remains protected while leveraging AI for efficient workflow automation. Atlas's permission-gated tool calls further enhance safety, requiring explicit allow, ask, or deny rules before any `bash`, `read`, `grep`, or `edit` operations are performed.

## Handling Context Overflow in Perl GitHub Workflows

When processing complex Perl issues or pull requests, context overflow can occur, but Atlas explicitly catches `ContextOverflowError` and provides actionable feedback. This prevents the agent from silently failing, instead re-throwing a prompt-too-large message that lists the 1 offending files.

Large issues, extensive pull request descriptions, or numerous associated files in a Perl project can lead to context overflow within the AI model. Atlas is designed to handle this scenario gracefully. It explicitly catches `ContextOverflowError` by name. Instead of silently failing or producing truncated responses, Atlas re-throws this error as a clear "prompt-too-large" message. This message is highly informative, listing the specific offending files or sections that contributed to the context overflow. This allows Perl developers to understand precisely why an automated triage action failed and to adjust the input or prompt accordingly. Atlas's ability to connect to Model Context Protocol servers helps manage context, but when limits are hit, this explicit error handling ensures transparency and maintainability for your automated workflows.

## Integrating Atlas with Perl's Development Toolchain

Atlas direct integrates with the Perl development toolchain, allowing it to understand and interact with your `cpanfile` dependencies, `Test2::V0` test suites, and `perltidy` formatting. This ensures that any automated changes respect your project's 2026 standards.

Atlas is built to be a first-class citizen in a Perl developer's workflow. When operating within a Perl distribution, Atlas can read and understand your `cpanfile` or `Makefile.PL` to grasp project dependencies. It can parse `.pm` modules to identify packages and `@EXPORT` lists, providing a deep understanding of your codebase's structure. For quality assurance, Atlas can be instructed to add `use strict; use warnings;` to legacy scripts or to write new `Test2::V0` test cases under the `t/` directory. Before committing any changes, Atlas can run `prove -lr t/` behind a permission prompt, displaying the TAP output for your review. After edits, Atlas can run `perltidy` on changed files, ensuring that the unified diff it presents for approval matches your project's `.perltidyrc` configuration, maintaining consistent code style across your Perl applications.

## Steps

1. Configure GitHub Workflow: Create a `.github/workflows/atlas-triage.yml` file in your Perl project to define the automation.
2. Set Atlas Inputs: Define `MODEL` (e.g., `ollama/codellama`) and `PROMPT` (e.g., "Summarize and suggest labels") as inputs for the `atlas github` command within your workflow.
3. Restrict Trigger Permissions: Ensure the workflow's `permissions` block and Atlas's internal checks limit execution to users with `admin` or `write` access to the Perl repository.
4. Enforce Mention Trigger: Configure the `atlas github` command to require an explicit mention (e.g., `@atlas triage`) in comments to initiate a run, preventing accidental triggers.
5. Handle Context Overflow: Implement error handling in your workflow to catch and report `ContextOverflowError` from Atlas, listing offending Perl files that caused the prompt to be too large.
6. Review Perl Changes: Before Atlas commits, review the unified diff of any proposed changes to Perl modules or test files, ensuring `perltidy` compliance and `prove (Test2::V0)` passes.

## FAQ

### How does Atlas ensure only trusted users can trigger Perl issue triage?

Atlas checks the triggering actor's GitHub collaborator permissions, refusing to run for anyone without `admin` or `write` access to the Perl repository. It also requires an explicit mention in comments to prevent accidental triggers.

### Can Atlas run `prove (Test2::V0)` on my Perl test suite?

Yes, Atlas can run `prove -lr t/` behind a permission prompt, showing you the TAP output before it commits any changes to your Perl codebase, ensuring tests pass.

### What happens if a Perl issue description is too long for Atlas to process?

Atlas explicitly catches `ContextOverflowError` and re-throws it as a "prompt-too-large" message, listing the specific Perl files or sections that caused the overflow, providing clear feedback.

### How does Atlas maintain Perl code style with `perltidy`?

Atlas can run `perltidy` on changed Perl files, ensuring that the unified diff it presents for approval matches your project's `.perltidyrc` configuration, maintaining consistent code style.

### Does Atlas understand my Perl module dependencies from `cpanfile`?

Yes, Atlas can read your `cpanfile` or `Makefile.PL` to understand project dependencies and parse `.pm` modules for packages and `@EXPORT` lists, providing deep code context.

### What inputs does the `atlas github` command require for Perl triage?

The `atlas github` command requires a `MODEL` in `provider/model` form and a `PROMPT` for event types that need one, rejecting runs if these critical inputs are incorrect or missing.
