## What it is
A GitHub Action that conditionally runs workflow jobs and steps based on which files were modified in a pull request, feature branch, or pushed commits. It enables selective CI execution, saving time and resources especially in monorepo setups.

## Use cases
- run integration tests only when relevant files changed
- skip deployment jobs for unaffected components in a monorepo
- conditionally lint only changed code in a PR
- detect modified files between feature branch and base branch
- filter workflow steps by changed paths in GitHub Actions

## When to choose
- you need per-job or per-step path filtering beyond GitHub's built-in on.push.paths
- you maintain a monorepo and want to avoid running the full pipeline on every change
- you need change detection across pull_request, push, and merge_group events

## When to avoid
- you only need simple top-level trigger path filters, which GitHub Actions supports natively
- your CI runs outside GitHub Actions
- you need change detection for non-git version control systems
