# Stacked PRs A **stack** is a chain of PRs where each PR's base branch is the **head** branch of the one below it, down to a PR whose base is the **trunk** (usually `main`): ``` main ← A (branch a) ← B (branch b) ← C (branch c) PR #A PR #B PR #C base: main base: a base: b bottom top ``` Each PR's diff shows only **its own layer** because it is compared against the branch below. The bottom is closest to trunk; the top is furthest. Foundational work (schema, shared types) goes low; things that depend on it (API routes, UI) go high. The invariant: **if code in one layer depends on code in another, the dependency must live in the same branch or a lower one.** ## Route first: native stack or hand-rolled chain GitHub shipped **native stacked pull requests** on 30.07.2026 (public preview, rolling out to all repos). A native stack is a first-class object on GitHub with its own number, a stack map in the merge box, webhook/REST/GraphQL surface, and server-side cascading rebase. A hand-rolled chain is just a set of PRs whose bases happen to point at each other; GitHub has no idea they are related. **They behave differently in ways that will bite. Establish which one you have before touching anything.** ```bash # 1. Is the CLI extension available locally? gh extension list | grep gh-stack # 2. Is this PR part of a native stack? `null` means it is not. gh api repos/<owner>/<repo>/pu
