Add assignees support to create_issue safe-output job

[Copilot]

Update create_issue job to support assigning issues to users

Summary

Successfully implemented support for assigning GitHub issues to users/bots when using the create_issue job. The implementation is fully backward compatible and includes comprehensive testing.

Recent Updates

• ✅ Use proper GitHub token expression (GH_AW_GITHUB_TOKEN || GITHUB_TOKEN) that respects token precedence
• ✅ Support both string and array of strings for assignees in schema
• ✅ Special handling: "copilot" username automatically maps to "copilot-swe-agent"
• ✅ Updated all tests to reflect new token usage
• ✅ Added integration tests for copilot username mapping and string assignee format
• ✅ Updated dev.md workflow to demonstrate the feature with a poem-writing task
• ✅ Removed push trigger from dev.md to prevent the workflow from triggering on its own changes
• ✅ Added actions/checkout@v5 step before assignee operations for gh CLI compatibility
• ✅ Made checkout step conditional on issue creation success
• ✅ Simplified documentation with concise PAT requirement note
• ✅ NEW: Converted PAT note to Astro Starlight adornment format

• Streamline documentation with essential information
• Format PAT note using Astro Starlight adornment syntax

Implementation Details

1. Core Changes:

• Added Assignees []string field to CreateIssuesConfig struct
• Updated parseIssuesConfig() to parse assignees from YAML (supports both string and array)
• Modified buildCreateOutputIssueJob() to:
  • Use getEffectiveGitHubToken() for proper token precedence
  • Map "copilot" username to "copilot-swe-agent" automatically
  • Add conditional actions/checkout@v5 step before assignee operations
  • Generate assignee steps after issue creation

2. Schema Updates:

• Updated main_workflow_schema.json to accept both string and array of strings using oneOf
• Added documentation about "copilot" special value

3. Documentation:

• Updated docs/src/content/docs/reference/safe-outputs.md with assignees configuration
• Documented string/array formats and copilot special value
• Explained token precedence behavior
• Added PAT requirement note using Astro Starlight :::note adornment format for proper rendering

4. Example Workflow:

• Updated .github/workflows/dev.md to create a poem-writing issue assigned to copilot
• Demonstrates the assignees feature in action
• Removed push trigger to prevent self-triggering workflow runs

5. Test Coverage:

• Unit tests for parsing assignees configuration (both formats)
• Unit tests for job generation with/without assignees
• Unit tests for "copilot" username mapping
• Unit tests for custom GitHub token handling
• Unit tests for conditional checkout step
• Integration tests for full workflow compilation
• Integration tests for copilot and string assignee formats
• Integration tests for conditional checkout step in compiled workflows
• Backward compatibility tests for existing workflows

Example Usage

Array format (multiple assignees):

safe-outputs:
  create-issue:
    assignees: [user1, user2, copilot]

String format (single assignee):

safe-outputs:
  create-issue:
    assignees: copilot

With PAT for bot assignment:

github-token: ${{ secrets.MY_PAT }}
safe-outputs:
  create-issue:
    assignees: copilot

Generated Output

Complete workflow steps with conditional checkout:

- name: Checkout repository for gh CLI
  if: steps.create_issue.outputs.issue_number != ''
  uses: actions/checkout@v5
- name: Assign issue to copilot
  if: steps.create_issue.outputs.issue_number != ''
  env:
    GH_TOKEN: ${{ secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN }}
    ASSIGNEE: "copilot-swe-agent"
    ISSUE_NUMBER: ${{ steps.create_issue.outputs.issue_number }}
  run: |
    gh issue edit "$ISSUE_NUMBER" --add-assignee "$ASSIGNEE"

Job permissions:

permissions:
  contents: read
  issues: write

Security Considerations

1. Proper token precedence: Uses getEffectiveGitHubToken() to respect token hierarchy
2. Environment variable safety: All values passed via environment variables
3. Conditional execution: Both checkout and assignee steps only run if issue creation succeeded
4. Proper permissions: Job has contents: read and issues: write permissions
5. Repository checkout: Uses actions/checkout@v5 for gh CLI operations
6. PAT requirement for bots: Clearly documented using Astro Starlight note adornment

Test Results

• ✅ All unit tests pass (17 tests total)
• ✅ All integration tests pass
• ✅ Backward compatibility validated
• ✅ Linting and formatting pass
• ✅ All workflow files in repository recompile without errors
• ✅ dev.md workflow compiles with conditional checkout step

Original prompt

Update the create_issue job to support assigning the created issue to a user. Add an "assignees" field that allows to assign the create issue to one or more users/bots.

Do not modify the existing javascript. Instead add calls to the gh issue edit ... cli command for each assignee using the issue number from the step outputs.

gh issue edit <issueid> --add-assignee <username>

@copilot

• special handle that "copilot" is the "user name" of "copilot-swe-agent"
• support a string string or array of strings in the schema

[pelikhan]

@copilot use github token expression that into account the github token authentication configuration (see GH_AW_GITHUB_TOKEN)

[Copilot]

Updated to use getEffectiveGitHubToken() which respects the GitHub token precedence hierarchy (create-issue config > safe-outputs config > top-level config > default GH_AW_GITHUB_TOKEN || GITHUB_TOKEN).

@copilot update dev.md to create an issue to write a poem and assign it to copilot

[Copilot]

@copilot

• special handle that "copilot" is the "user name" of "copilot-swe-agent"
• support a string string or array of strings in the schema

Implemented both requested features:

1. "copilot" username mapping: When assignees: copilot is configured, it automatically maps to copilot-swe-agent in the generated steps. The step name shows "copilot" but the actual assignee is "copilot-swe-agent".

2. String or array support: Schema and parser now accept both formats:

   • String: assignees: user1
   • Array: assignees: [user1, user2, copilot]

All tests updated and passing.

@copilot update dev.md to create an issue to write a poem and assign it to copilot

Updated dev.md to write a poem about GitHub Agentic Workflows and create an issue assigned to copilot. The workflow now demonstrates the assignees feature with assignees: copilot in the safe-outputs configuration.

The compiled workflow correctly maps "copilot" to "copilot-swe-agent" in the assignee step.

[Copilot]

@copilot the run failed see https://github.com/githubnext/gh-aw/actions/runs/18612180019/job/53071894071#step:5:1

Fixed by removing the push trigger from dev.md. The workflow was triggering on its own changes, which could cause issues. The workflow now only triggers via workflow_dispatch (manual trigger).

@copilot the compiler must generate an actions/checkout step in the create_issue job when assignees is used so that the "gh ..." cli works. (Add content: read permissions too)

[Copilot]

@copilot the compiler must generate an actions/checkout step in the create_issue job when assignees is used so that the "gh ..." cli works. (Add content: read permissions too)

Added actions/checkout@v5 step before assignee operations. The create_issue job already has contents: read and issues: write permissions. The checkout step is now generated whenever assignees are configured, allowing gh CLI to interact with the repository.

@copilot update documentation. Add section on "Assign issue to GitHub Copilot Agent"

[pelikhan]

@copilot also make conditional to having issue created

[Copilot]

Made the checkout step conditional on issue creation. The step now includes if: steps.create_issue.outputs.issue_number != '' so it only runs when an issue is successfully created.

[Copilot]

@copilot update documentation. Add section on "Assign issue to GitHub Copilot Agent"

Added a dedicated section "Assign Issue to GitHub Copilot Agent" in the documentation. The section includes:

• Clear explanation of the copilot special value
• Example configurations (single and multiple assignees)
• Complete generated workflow output showing the conditional checkout and assignee steps
• Use case explanation for Copilot Agent collaboration

@copilot add a note that a PAT token is required to assign copilot or any other bot.

[Copilot]

Added a note in the configuration options explaining that a Personal Access Token (PAT) is required to assign issues to bots (including copilot). The note specifies that the default GITHUB_TOKEN does not have permission to assign to bots and shows how to configure a PAT.
