description	Create a new worktree and branch from a GitHub issue
disable-model-invocation	true

The user wants to create a new worktree with a new branch based on a GitHub issue. The issue number (e.g. #72 or 72) is provided as the argument: $ARGUMENTS.

If no issue number argument was provided, ask the user which issue they want.

Follow these steps:

1. Fetch the GitHub issue using gh issue view <number> to get the issue title and body.

2. Look at existing branch names by running git branch -r --sort=-committerdate to understand the repo's naming conventions.

3. Think of a good branch name that:

   • Starts with the issue number (e.g. 72-descriptive-name)
   • Uses kebab-case
   • Is concise but clearly describes what the issue is about
   • Matches the style of existing branch names in the repo
   • Has no "/" prefix

4. Verify that the branch and worktree path (../ordning-<branch-name>) aren't already in use by checking git branch -r and git worktree list. If either already exists, pick a different name and repeat untill you find one that is free.

5. Pick the branch name and proceed directly — do not ask the user to confirm it. Just state the name you chose and continue. For example:

   Issue #72: "Add export functionality for datasets"
   Branch: 72-dataset-export
   

6. Assign the issue to the user (if not already assigned to them) by running gh issue edit <number> --add-assignee @me. This is idempotent — running it when the user is already an assignee is harmless.

7. Fetch latest from remote by running git fetch origin.

8. Create the worktree from master:

   git worktree add ../ordning-<branch-name> -b <branch-name> origin/master
   

9. Copy gitignored files to the new worktree by running the wi CLI tool:

   wi init <absolute-path-to-this-repo> <absolute-path-to-new-worktree>
   

   This copies build outputs, .env files, and other gitignored files from the current repo to the new worktree so it's ready to build and run. Use absolute paths for both arguments. Run wi help for more details on usage.

10. Tell the user how to start working there. Print a message like:

Worktree ready! To start Claude in the worktree, run:
cd ../ordning-<branch-name> && claude
