start-issue

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

Critical Requirements

• state.json update is MANDATORY. After creating the branch, you MUST update the issue status to running in ${MARSHROOM_STATE:-~/.config/marshroom/state.json}. If this fails, stop and report the error — do NOT silently continue.
• Use marsh start if available; otherwise fall back to direct jq atomic write (see step 10).

Steps

1. Read ${MARSHROOM_STATE:-~/.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 (MANDATORY):
    • First try: marsh start #{issueNumber}
    • If marsh is not found in PATH, fall back to direct atomic update:

      STATE_FILE="${MARSHROOM_STATE:-~/.config/marshroom/state.json}"
      TMP="$(mktemp "${STATE_FILE}.XXXXXX")"
      jq --argjson n ISSUE_NUMBER '.cart |= map(if .issueNumber == $n then .status = "running" else . end)' \
        "$STATE_FILE" > "$TMP" && mv -f "$TMP" "$STATE_FILE"
      

      Copy
    • Verify the update succeeded by reading state.json and confirming status is running
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.
