GitHub Sub-issue Creator

This skill defines rules and procedures for creating GitHub sub-issues.

Workflow

  1. Identify the parent issue number and repository.
  2. Create a new issue using the github-issue-creator skill.
  3. Get the REST API ID of the created issue.
  4. Add the issue as a sub-issue to the parent issue using the REST API.
  5. Report the sub-issue URL to the user.

Creating a Sub-issue

Sub-issues are regular issues linked to a parent issue. The gh CLI does not have a direct option to create sub-issues, so use the REST API via gh api command.

Step 1: Create the Issue

Use the github-issue-creator skill to create the issue. This ensures that issue templates, title guidelines, and language settings are applied.

Note the issue number from the output URL (e.g., https://github.com/OWNER/REPO/issues/123 → issue number is 123).

Step 2: Get the Issue ID

Get the REST API ID of the created issue. This is the numeric id field, not the node_id or issue number.

gh api repos/OWNER/REPO/issues/123 --jq .id

Step 3: Add as Sub-issue

Add the issue as a sub-issue to the parent issue.

gh api repos/OWNER/REPO/issues/PARENT_ISSUE_NUMBER/sub_issues -X POST -F sub_issue_id=ISSUE_ID

Example

Creating a sub-issue for parent issue #100 in octocat/hello-world.

First, use the github-issue-creator skill to create an issue. Assume the created issue URL is https://github.com/octocat/hello-world/issues/123.

Then, get the issue ID and add as sub-issue:

# Get the issue ID
gh api repos/octocat/hello-world/issues/123 --jq .id
# Output: 3000028010

# Add as sub-issue
gh api repos/octocat/hello-world/issues/100/sub_issues -X POST -F sub_issue_id=3000028010
