Stop letting monster PRs die in review purgatory.
A Claude Code plugin that splits large PRs into chains of small, reviewable PRs. It analyzes your diff semantically — using tree-sitter for per-function granularity — builds a dependency DAG, verifies the split is lossless, and creates the PRs with proper base branches and merge order.
/plugin marketplace add emilhe/split-pr
/plugin install split-pr@emilhe-split-pr/split-pr # split current branch vs main
/split-pr --base develop # different base branch
/split-pr --name auth-refactor # custom prefix for PR titles
/split-pr --threshold 600 # larger PRs allowed (default: 400 lines)
/split-pr --max-files 15 # max files per PR (default: 10)
/split-pr --bulk "vendor/" # skip AST analysis for vendored paths
/split-pr --auto # skip interactive review
/split-pr --pr 42 # split an existing PR

AI does the thinking (topic classification, dependency detection). Code does the math (AST analysis, DAG operations, diff parsing, lossless verification).
- Tree-sitter AST analysis — splits large files into per-function virtual hunks, so different functions can go to different PRs
- Hunk-level splitting — works with messy, entangled commits
- DAG-based dependencies — independent topics can be reviewed in parallel
- Lossless verification — every hunk accounted for before any PRs are created
- Smart grouping — vendored code stays bundled, tests travel with the code they test
- Tracking issue — auto-created checklist with clickable DAG and merge order
