start-issue

Start working on a Marshroom cart issue in the current repository.

Steps:

1. •Read ~/.config/marshroom/state.json and parse the JSON
2. •Extract the cart array. If the cart is empty, tell the user to add issues in the Marshroom app
3. •Run git remote get-url origin to get the current repo's remote URL
4. •Extract owner/repo from the remote URL (handle both HTTPS and SSH formats)
5. •Filter cart entries where repoCloneURL (HTTPS) or repoSSHURL (SSH) matches the current remote. Compare by extracting owner/repo from each
6. •If no matching cart entries, tell the user this repo has no cart issues
7. •If $ARGUMENTS contains an issue number, find that entry; otherwise if multiple matches, list them and ask the user to pick one
8. •Run git checkout main && git pull origin main to ensure main is up to date
9. •Create and checkout the branch: git checkout -b {branchName} The branch name should be Feature/#N or HotFix/#N. N is issue number.
10. •Update issue status: run marsh start #{issueNumber} (if marsh is available in PATH). If marsh is not found, skip this step silently.
11. •Inject issue context:
    • •Read the issueBody field from the matched cart entry
    • •If non-null, display it under a "## Issue Details" header
    • •This gives the agent full context about what needs to be done
12. •Confirm the branch was created and display:
    • •Issue: #{issueNumber} {issueTitle}
    • •Branch: {branchName}
    • •Repository: {repoFullName}
    • •Status: running
13. •Ask the user permission to start planning to resolve issue. If the user allows it, starts planning using /plan mode.
