Stack Mode

Shared contract for commands that need to operate across a whole stack of dependent PRs in one invocation. Used by /pr-review --stack and /fix-pr --stack.

The goal is one simple thing: when a PR is part of a stack targeting a common base branch, loop the command's normal workflow across every PR in the stack in base-to-tip order and emit one consolidated summary on the stack root.

When to Use

Load this skill when a command accepts a --stack flag (or auto-detects stack membership) and needs to iterate its normal workflow across multiple PRs.

Do NOT load this skill for single-PR workflows. The per-PR workflow stays unchanged; stack mode wraps it.
