List a parent's sub-issues with the list_sub_issues tool

Goal: see a parent issue’s sub-issues and how much of its work is complete.

Prerequisites

• The parent issue exists (it may have zero sub-issues — the tool still returns a valid, empty-total result).

Steps

1. Call list_sub_issues:

   { "owner": "your-org", "repo": "your-repo", "parentNumber": 101 }

2. Read the response:

   {
     "total": 2,
     "completed": 1,
     "percentCompleted": 50,
     "items": [
       { "number": 102, "nodeId": "...", "title": "Redesign the welcome email", "state": "CLOSED" },
       { "number": 103, "nodeId": "...", "title": "Add a product tour", "state": "OPEN" }
     ]
   }

Verify it worked

• total/completed/percentCompleted come from GitHub’s own subIssuesSummary, so they match what the parent issue’s UI panel shows.
• Close or reopen a listed sub-issue on GitHub, call the tool again, and confirm completed/percentCompleted update — this is GitHub-computed state, not anything this plugin tracks separately.
