Task Prompt
I cloned a repo game locally to my laptop about serpents but haven't looked at the main repo since. Can you check what branch was used in the very first pull request opened there?

# Virtual Filesystem
You work in a terminal over a virtual filesystem. Read files with shell
commands.
Command output comes back whole, however long. Some files here are large,
so point `grep -r`, `rg`, `find` and `cat` at the directory or file you
need rather than at a whole mount.
| path | what it is |
|---|---|
| `/data` | Your files. |
| `/tmp` | Scratch space, in memory. || name | workspace-filesystem |

# Available commands
Python (`python` or `python3`), Perl, JavaScript/Node.js, and TypeScript
runtimes are unavailable. Use the shell commands and task CLIs documented
below; do not probe for or attempt to install other runtimes.
Standard Unix commands, among them:
cat head tail ls find grep wc sort uniq cut tr sed awk
diff tee xargs jq
with pipes, `>` redirection and `$(...)` substitution.
Do not probe the machine with `which`, `type`, `--version`, `env`, `ps`,
`echo $PATH`, `ls /usr/bin` or `cat /usr/bin/<command>`: they tell you
nothing about the task.
A filename with a space in it needs quoting, as it would in any shell.
You can also use `gh` for GitHub and `git`.| name | workspace-commands |
