Slices a large working branch into a chain of smaller, reviewable PRs. Detects adopter-defined migration-class files (forces a migration PR first), builds a dependency graph, writes an overview.md and per-PR spec folder under .tmp/pr-slicer, then dispatches pr-slicer-executor sub-agents (optionally in git worktrees) to build each PR. Main session keeps the remote side — push, gh pr create, rebase cascade. Use when asked to "slice this PR", "pr-slicer", "break this branch into PRs", "chop this up into smaller PRs".
Run the pr-slicer workflow on your current branch to generate a plan, slice the work into PRs, and dispatch executors for review.

To break a large feature branch into smaller pull requests, the workflow slices your commits into a chain of manageable PRs by building a dependency graph and dispatching sub-agents to assemble each one. You simply run the command on your working branch.
Dependency graph building for chained pull requests works by detecting migration-class files to force a migration PR first, then mapping remaining changes to establish the order. This structured plan under .tmp/pr-slicer dictates how executor sub-agents assemble each PR.
Yes, you can use git worktree to parallelize pull request generation. The workflow optionally dispatches pr-slicer-executor sub-agents within isolated git worktrees, allowing concurrent assembly and validation of PRs without interfering with your main working directory.
You need GitHub CLI to automate branch slicing and PR creation because the main session manages remote operations including pushing branches and running gh pr create. The workflow orchestrates the entire remote side, including rebase cascades across the PR chain.
The best way to handle migration files when splitting a branch is to let the workflow detect adopter-defined migration-class files automatically. This forces a migration PR to be generated first, ensuring dependency resolution before subsequent feature PRs are dispatched.
Splitting a large pull request simplifies code review and integration by breaking the work into a sequence of smaller, reviewable PRs. This approach generates a structured overview and per-PR specs, making the changes easier to validate before merging.
