## What it is
ghstack is a command-line tool that submits stacks of Git commits to GitHub as separate, dependent pull requests. It supports updating, rebasing, and landing stacked diffs, with optional AI-generated PR descriptions via Claude or Codex.

## Use cases
- submit stacked diffs to github
- create one pull request per commit in a stack
- update a pull request by amending a commit
- land a stacked pull request from the cli
- manage dependent prs on github
- generate pr descriptions with claude or codex

## When to choose
- you develop features as a series of dependent commits and want reviewable per-commit PRs
- you work on large codebases like PyTorch where stacked diffs are the norm
- you want to update or rebase a whole stack with a single command

## When to avoid
- you only need simple single-branch pull requests via the GitHub UI
- you prefer tools like Graphite or sapling for stack management
- your workflow relies on merge commits, which ghstack does not support

- function: version-control, developer-tools, code-review, cli
