Create Branch

Create a git branch with the correct type prefix and a descriptive name following Sentry conventions.

When to Use

• You need to create a new git branch that follows the repository's naming convention.
• You are starting a new piece of work from the default branch and need help classifying it as feat, fix, docs, or another branch type.
• You want the branch name proposed from either the task description or the current local diff.

Step 1: Get the Username Prefix

Run gh api user --jq .login to get the GitHub username.

If the command fails (e.g. not authenticated), ask the user for their preferred prefix.

Step 2: Determine the Branch Description

If $ARGUMENTS is provided, use it as the description of the work.

If no arguments, check for local changes:

git diff
git diff --cached
git status --short

• Changes exist: read the diff content to understand what the work is about and generate a description.
• No changes: ask the user what they are about to work on.

Step 3: Classify the Type

Pick the type from this table based on the description:

Type	Use when
feat	New user-facing functionality
fix
