close-issue

Close a GitHub issue with a brief comment summarizing the fix that was applied.

Supported arguments: an issue number (required), and optionally a short description of the fix. If no description is provided, infer the fix from the current branch's diff against main.

Requested arguments: $ARGUMENTS

Steps:

1. Parse arguments

   Extract the issue number from $ARGUMENTS. If a description is also provided, use it as the comment body. Otherwise, proceed to step 2 to infer one.

2. Infer the fix summary (skip if a description was provided)

   Fetch the issue title for context, then check the current branch diff:

   gh issue view <number> --json title,body
   git log origin/main..HEAD --oneline
   git diff origin/main...HEAD --stat
   

   Write a 1-3 sentence comment covering the root cause and what was changed to fix it. Keep it concise and factual. Do not repeat the issue title back.

3. Post the comment and close the issue

   gh issue close <number> --comment "<summary>"
   

4. Report back

   Output the issue URL and confirm it was closed.
