SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Branch-heavy development creates review fatigue and shaky merges. The Branch Splitter helps you decompose a large, messy branch into a DAG of smaller, independent PRs that are easier to review, test, and integrate.

Core Features & Use Cases

Atomic PR decomposition: each PR contains a single logical change.
Dependency-aware merging: preserves the overall original diff when PRs are merged in valid topological orders.
Documentation-conscious splitting: respects existing docs and claims during decomposition.

Quick Start

Decompose a sprawling feature branch into a set of independently reviewable PRs.

FAQPage Schema

How do I split a large feature branch into smaller, independent PRs?▼

To split a large feature branch into independent PRs, decompose the overall diff into a DAG of atomic changes. This enables independent review and topologically safe trunk merges while preserving the original content.

What is a PR DAG and how does it help with branch merging?▼

A PR DAG is a directed acyclic graph of atomic pull requests mapped by branch dependencies. It ensures topologically safe merges, preventing integration conflicts by validating content invariants against the base-diff.

When should I decompose a branch into a dependency-aware merge DAG?▼

Decompose a branch into a merge DAG when it contains multiple unrelated changes, refactors, or documentation updates. This reduces review fatigue and shaky merges by isolating atomic logical changes.

Do I need a base-diff and defined branch dependencies to split branches?▼

Yes, splitting branches requires a clear base-diff and defined branch dependencies. You must also establish a plan for content invariants to validate during the topological merge process.

What is the best way to break down a messy branch for independent code review?▼

The best way to break down a messy branch is atomic PR decomposition, grouping each single logical change into its own pull request. This respects existing documentation and creates a dependency-aware merge structure.
