Understanding GitHub Actions Before You Let Them Run

At some point, almost every GitHub repository grows beyond being a place to store source code. Maybe you want your application to build automatically after every commit, run unit tests before a pull request is merged, publish a release when you create a tag, or deploy a Jekyll site whenever new content is pushed. Before long, someone suggests the same solution:

“Just use GitHub Actions.”

On the surface, it really is that simple. You add a workflow file, commit it to the repository, and GitHub begins executing it whenever the configured trigger occurs.

on:
  push:
    branches:
      - main

Or perhaps you decide you’d rather trigger the workflow manually while you’re testing it:

on:
  workflow_dispatch:

For many developers, that’s where the learning process ends. The workflow runs successfully, a green checkmark appears in the repository, and everyone moves on to the next task without giving much thought to what was actually introduced into the project.

The workflow itself may have come from GitHub’s documentation, the GitHub Marketplace, a blog post, Stack Overflow, or an AI coding assistant. The source almost doesn’t matter. What matters is that you’ve added automation capable of executing code on behalf of your repository.

There’s nothing inherently wrong with that. In fact, GitHub Actions have become one of my favorite features of the platform. I use them to build applications, publish releases, deploy websites, generate documentation, and eliminate repetitive tasks that would otherwise have to be performed manually. A well-designed workflow makes releases more consistent and allows me to focus on solving problems instead of repeating the same commands over and over again.

What I try not to forget is that every GitHub Action is still software, even if it’s described in a YAML file.

When I see a step like this:

- uses: actions/checkout@v4

or

- uses: vendor/example-action@v2

I don’t immediately think of it as configuration. I think of it as code that someone else wrote and that my workflow is about to execute.

Before I commit that workflow, I’ll usually spend a few minutes learning more about the action itself. I’ll visit the repository to understand what it does, review the documentation, and look at the source if it’s a relatively small project. If the action requests repository permissions or interacts with secrets, I want to understand why.

For example, if a workflow only needs to publish a release, I’ll compare that requirement against the permissions it’s requesting:

permissions:
  contents: write

If I see broader permissions than I expect, that’s usually a good reason to stop and understand whether they’re actually necessary.

The same applies to secrets. If a workflow references credentials, I want to understand exactly how they’re being used:

env:
  APPLE_ID: $
  APPLE_APP_PASSWORD: $

That doesn’t mean the workflow is unsafe. It simply means those credentials become part of the automation, and I want to understand how they’re handled before I trust the workflow to run unattended.

That’s the same approach I take in my role as an ISSO. I don’t assume an action is trustworthy because it’s popular, has thousands of stars, or was suggested by an AI assistant. Popularity isn’t the same as understanding. Instead, I try to answer a few practical questions. Who maintains this action? What code will it execute? What permissions does it require? Does it access secrets? If I pin this version today, would I still be comfortable running it six months from now?

Once I started thinking about GitHub Actions as software instead of configuration files, reviewing them became much more straightforward. A workflow isn’t just automation—it’s another component of the software supply chain. Like any other software I introduce into an environment, I want to understand what it does before I ask it to run on my behalf.

What Are GitHub Actions?

GitHub Actions are GitHub’s built-in automation platform.

Instead of manually performing repetitive tasks every time something happens in a repository, GitHub can respond automatically to events such as:

• Code pushes
• Pull requests
• Releases
• Tags
• Scheduled jobs
• Manual workflow dispatches

When one of those events occurs, GitHub looks for workflow definitions inside .github/workflows and executes them on a runner.

Think of a workflow as the overall recipe and an Action as one reusable ingredient within that recipe.

          ├── Restore Dependencies
          ├── Build
          ├── Test
          └── Publish Release

A typical workflow combines reusable Actions with commands you’ve written yourself.

jobs:
  build:
    runs-on: ubuntu-latest

    permissions:
      contents: read

    steps:
      - uses: actions/checkout@v4

      - name: Build
        run: swift build

      - name: Run Tests
        run: swift test

The distinction between uses: and run: is one of the most important concepts to understand.

run: executes commands you’ve written.

uses: downloads and executes software maintained elsewhere.

That difference is where security discussions begin.

What Actually Happens When GitHub Sees uses:?

One of the things I wish more GitHub Actions tutorials explained is what actually happens when a workflow encounters a uses: statement. It’s easy to think of it as just another line of YAML, but that single line tells GitHub to retrieve and execute software as part of your workflow.

For example, consider this step:

- uses: actions/checkout@v4

At first glance it doesn’t appear to do much, but behind the scenes GitHub locates the referenced repository, downloads the specified version of the action, prepares the runner environment, and executes the action according to how it was written.

From the workflow author’s perspective, it’s just one line:

- uses: actions/checkout@v4

On the runner, however, that line results in code being executed.

Depending on the implementation, an action might execute JavaScript, start a Docker container, run a Composite Action, or invoke one or more shell scripts. The workflow syntax is the same regardless of the implementation—the difference is in what actually happens after GitHub begins processing the workflow.

If I’m curious about what an action is doing, one of the first things I’ll do is inspect the repository that publishes it. For example, I might clone it locally and look at the implementation:

git clone https://github.com/actions/checkout.git

cd checkout

From there I can inspect the repository structure:

ls -la

Many actions include an action.yml file that describes how the action should be executed:

cat action.yml

If it’s a JavaScript action, I’ll often see an entry point similar to this:

runs:
  using: node20
  main: dist/index.js

If it’s a Composite Action, I may instead find that it simply orchestrates a series of shell commands:

runs:
  using: composite
  steps:
    - run: ./script.sh

And if the action is container-based, the metadata will reference a Docker image instead:

runs:
  using: docker
  image: Dockerfile

None of those implementation choices are inherently better or worse than the others. The important point is that uses: isn’t a special GitHub keyword that magically performs a task. It’s a reference to software that someone wrote, published, and asked GitHub to execute inside your workflow.

That’s why I think it’s worth spending a few minutes understanding an action before adding it to a project. Once I started viewing GitHub Actions as software instead of configuration, it became much more natural to review who maintains them, how they’re implemented, what permissions they require, and whether they’re appropriate for the environment where they’ll be running.

Where Does a GitHub Action Actually Run?

Another question I don’t see discussed very often is where a GitHub Actions workflow actually executes. It’s an important detail because the answer helps define what the workflow can access and how much trust you’re placing in the environment that’s running your automation.

By default, GitHub Actions don’t execute on your local computer or inside the GitHub repository itself. Instead, GitHub provisions a temporary virtual machine, known as a runner, specifically for the workflow. The workflow executes on that runner, and once the job has completed, the virtual machine is discarded.

You can see which operating system a workflow is requesting by looking at the runs-on directive:

jobs:
  build:
    runs-on: ubuntu-latest

Or perhaps the workflow needs to build a macOS application:

jobs:
  build:
    runs-on: macos-latest

GitHub maintains hosted runners for Linux, Windows, and macOS, which makes it possible to build, test, and release software across multiple operating systems without maintaining your own infrastructure. For many projects, those hosted runners are all that’s needed.

Sometimes, though, organizations have requirements that GitHub-hosted runners can’t satisfy. A build may need access to an internal package repository, an on-premises code signing server, specialized hardware, or systems that aren’t exposed to the public internet. In those situations, GitHub Actions can use a self-hosted runner instead.

From the workflow’s perspective, the change is surprisingly small:

jobs:
  build:
    runs-on: self-hosted

Or perhaps the organization has labeled runners for specific purposes:

jobs:
  build:
    runs-on:
      - self-hosted
      - macOS
      - production

That one change, however, has significant implications.

A third-party action running on a GitHub-hosted runner is typically executing inside a temporary virtual machine that GitHub provisions for the duration of the job. When the workflow finishes, that environment is destroyed, reducing the likelihood that artifacts from one job remain available to another.

The same workflow running on a self-hosted runner may have access to an entirely different environment. Depending on how the runner has been configured, it could communicate with internal services, reach build infrastructure, interact with package repositories, use locally installed signing certificates, or access other enterprise resources that don’t exist on a GitHub-hosted runner.

The action itself hasn’t changed, but the environment surrounding it certainly has.

That’s one of the reasons I like to understand more than just the workflow syntax. Before I approve or write a workflow, I want to know where it’s going to execute, what resources that runner can access, and whether those capabilities are actually required for the job it’s performing. A workflow that seems perfectly reasonable on a temporary GitHub-hosted runner may deserve additional scrutiny before it’s allowed to execute inside an organization’s internal environment.

Understanding the runner doesn’t make GitHub Actions more complicated—it simply provides the context needed to make better decisions about what automation is appropriate and where that automation should be allowed to run.

Why AI Recommends GitHub Actions So Often

If you’ve been using AI coding assistants recently, you’ve probably noticed that GitHub Actions show up in their suggestions quite often. Ask how to build a macOS application, automate testing, publish a GitHub Release, deploy a Jekyll site, or even generate documentation, and there’s a good chance the response will include one or more GitHub Actions.

There’s a practical reason for that.

Modern AI models are trained to recognize common software development patterns. When an existing GitHub Action already solves a well-understood problem, it’s usually more useful to recommend that solution than to generate an entirely new implementation from scratch. Thousands of developers have already solved problems like checking out a repository, setting up a programming language, uploading release assets, or deploying a website. Reusing those building blocks often results in a simpler and more maintainable workflow.

For example, an AI-generated workflow might include something like this:

steps:
  - uses: actions/checkout@v4

  - uses: actions/setup-python@v5

  - uses: actions/upload-artifact@v4

With only a few lines of YAML, you’ve introduced multiple pieces of software into your workflow, each maintained by a different project and each performing a specific task.

From the AI’s perspective, that’s often the right answer. Rather than producing hundreds of lines of shell scripting, it can assemble a workflow using components that are already designed for those jobs.

The same thing happens when you ask AI to automate releases. Instead of writing custom logic to package files, upload artifacts, or publish a GitHub Release, it will often recommend actions that already perform those tasks.

The result is that a single prompt can create a surprisingly capable CI/CD pipeline in just a few seconds.

That’s incredibly powerful, but it’s also worth remembering what actually happened. AI didn’t create an isolated workflow consisting entirely of code that you wrote. It assembled a solution using software maintained by other people.

Whenever I receive a workflow from an AI assistant, I treat it the same way I would if a colleague submitted it in a pull request. Before I commit it to the repository, I read through the workflow to understand what each step is doing.

If I encounter an unfamiliar action, I’ll usually visit the repository to learn more about it before deciding whether to use it.

git clone https://github.com/actions/upload-artifact.git

cd upload-artifact

I’ll often inspect the action metadata to understand how it’s implemented:

cat action.yml

And if the workflow references secrets or requests repository permissions, I’ll review those sections just as carefully:

permissions:
  contents: write

env:
  GITHUB_TOKEN: $

Most of the time, the workflow turns out to be perfectly reasonable. The goal isn’t to distrust AI-generated code or avoid GitHub Actions altogether. In fact, I use both regularly because they save an incredible amount of time.

The important point is that AI doesn’t eliminate the need to understand what you’re adding to your project. It accelerates development by assembling existing components, but those components are still software that deserves the same level of review as any other dependency.

Whether a workflow comes from the GitHub Marketplace, a blog post, official documentation, a coworker, or an AI coding assistant, my process is the same. I read it, understand what it’s doing, review the repositories it depends on, and make an informed decision about whether I’m comfortable allowing that automation to run in my environment.

Start by Understanding the Workflow

When I come across a new GitHub Action, the first thing I read isn’t the Action itself—it’s the workflow that calls it.

The workflow tells the story.

It explains what event starts the automation, which jobs are going to execute, what permissions are requested, what secrets are being used, and which third-party Actions are involved. Before I spend time reading another developer’s repository, I want to understand what my own repository is asking GitHub to do.

One command gives me a surprisingly good overview of that dependency chain:

grep -R "uses:" .github/workflows

Every uses: statement represents another piece of software that will execute as part of the workflow. Some are maintained by GitHub, others by software vendors, and many by individual developers contributing to the open-source community. None of those categories are inherently better or worse, but each one deserves a quick review before it becomes part of your build pipeline.

Reading the workflow first also makes the rest of the review process much easier. Instead of looking at an Action in isolation, you understand the context in which it’s being used. Is it checking out source code? Publishing a release? Uploading build artifacts? Signing an application? Once you know why an Action exists, it’s much easier to determine whether it’s appropriate for the job.

Why I Prefer Pinning Actions

One of the first things I usually change in an AI-generated or sample GitHub Actions workflow is how the actions themselves are referenced. It’s a small modification, but I think it makes the workflow much more predictable over time.

Most examples you’ll find in documentation, blog posts, or even AI-generated workflows reference actions by a version tag because they’re concise and easy to understand.

- uses: vendor/example-action@v3

There’s nothing inherently wrong with using version tags. In fact, they’re appropriate for many projects, especially when you’re comfortable automatically receiving updates within a major release.

The challenge is that a tag is a moving reference. At some point, the maintainer may publish a newer release under that same major version, which means your workflow could execute different code than it did the last time it ran.

That’s perfectly acceptable if you’ve decided that’s how you want to manage updates. Personally, I prefer making those decisions explicitly.

When I’m reviewing a third-party action, I want the code I reviewed to be the exact code my workflow executes. Pinning an action to a specific commit SHA gives me that consistency.

- uses: vendor/example-action@8d4f2c7d7f4c9c1d5d5fd3e0f4b3a8d2b0e1a123

If I’m curious about where that SHA came from, I can inspect the repository myself:

git clone https://github.com/vendor/example-action.git

cd example-action

Then I can view the commit history and identify the exact commit I intend to reference:

git log --oneline

Or retrieve the full commit identifier directly:

git rev-parse HEAD

Once I’ve reviewed that version, I know exactly what my workflow is going to execute every time it runs. If I decide to upgrade later, that’s an intentional decision rather than something that happened because a tag now points to different code.

That doesn’t mean pinned actions never need maintenance. Quite the opposite. I still want to periodically review newer releases, evaluate bug fixes and security updates, and decide whether it’s time to move to a newer commit. The difference is that the update happens on my schedule rather than automatically.

It’s also worth noting that pinning an action doesn’t magically make it trustworthy. If the underlying action is poorly written or inappropriate for your environment, referencing a specific commit won’t change that. What pinning does provide is consistency and reproducibility. The workflow executes the same code tomorrow that it executed today, and if it changes in the future, it’s because I made a deliberate choice to update it.

For projects where security, change management, or reproducibility are important, I think that’s a worthwhile tradeoff. I would much rather review an update intentionally than discover after the fact that my workflow has been running different code than the version I originally approved.

Permissions Deserve More Attention Than They Usually Get

One area of GitHub Actions that I think deserves far more attention is workflow permissions. GitHub has made significant improvements over the years by giving repository owners much more control over what a workflow is allowed to do, yet I still see plenty of examples that simply accept the defaults without ever asking whether those permissions are actually necessary.

Whenever I review a workflow, one of the first sections I look for is the permissions block.

permissions:
  contents: read

It doesn’t look particularly interesting, but it’s one of the most important parts of the workflow because it defines what the automatically generated GITHUB_TOKEN is allowed to do while the workflow is running.

For many workflows, read-only access is enough. If the job only needs to check out the repository, compile an application, or execute tests, there’s often no reason to grant additional repository permissions.

permissions:
  contents: read

steps:
  - uses: actions/checkout@v4

A release workflow, however, has different requirements. If the workflow needs to create a GitHub Release or upload release assets, it will need additional access.

permissions:
  contents: write

The important point is that the permission is granted because the workflow actually needs it—not simply because it’s convenient.

GitHub also allows permissions to be scoped more narrowly. Instead of giving every job in a workflow the same capabilities, I prefer granting elevated permissions only to the jobs that require them.

For example, a workflow might build and test software using read-only access:

jobs:
  build:
    permissions:
      contents: read

While a separate release job receives write access because it’s responsible for publishing artifacts:

jobs:
  release:
    permissions:
      contents: write

That approach follows the same principle we apply throughout IT: least privilege.

When I review a workflow, I’ll often ask simple questions. Does this job really need write access? Does it actually need permission to create releases? Could it perform its task with fewer privileges? Those aren’t complicated questions, but they’re often enough to identify permissions that were copied from an example workflow and never revisited.

The goal isn’t to make workflows difficult to write or maintain. It’s to ensure they have exactly the permissions they need to perform their intended function—and nothing more. If a workflow only needs to read the repository, that’s all I want to grant it. If another job genuinely needs additional capabilities, I want those permissions to be intentional, documented, and limited to the part of the workflow that actually requires them.

The fewer permissions an action has, the fewer opportunities it has to affect the repository if something unexpected happens. That’s a simple idea, but it’s one that carries over from virtually every other area of system administration and security. GitHub Actions are no different.

Pay Attention to Secrets

Secrets are another part of a workflow where I intentionally slow down. Most GitHub Actions are harmless because they don’t need access to anything beyond the repository itself. The moment a workflow begins referencing secrets, though, it’s worth taking a closer look at how those credentials are being used.

A simple example might look like this:

env:
  API_KEY: $

There’s nothing inherently wrong with that. In fact, storing credentials in GitHub Secrets is almost always preferable to embedding them directly into a workflow or checking them into source control.

The questions I ask come afterward.

Why does this workflow need the secret? Which step actually uses it? Does every job in the workflow have access to it, or could the secret be scoped more narrowly?

For example, it’s common to see a secret defined at the workflow level:

env:
  API_KEY: $

That makes the value available throughout the workflow.

If only one step needs the credential, though, I generally prefer exposing it only where it’s required:

- name: Upload Package
  env:
    API_KEY: $
  run: ./upload.sh

The fewer places a secret exists, the fewer opportunities there are for it to be exposed through debugging, logging, or future changes to the workflow.

Whenever I’m reviewing a workflow, I’ll also follow the secret through the rest of the automation. If it’s passed into a shell script, I’ll usually inspect that script to see how it’s handled.

grep -R "API_KEY" .

I’m looking for simple things that are easy to miss during development. Is the script enabling shell tracing with set -x? Does it print environment variables for debugging? Is the secret written to a temporary file? If an API request fails, could the response or request headers end up in a log?

For example, these are the kinds of commands that deserve a second look during a review:

echo "$API_KEY"

printenv

set -x

None of those commands are automatically vulnerabilities. They can all be useful while troubleshooting. The important question is whether they’re still appropriate in a production workflow or whether they’re leftovers from a debugging session that quietly became permanent.

Sometimes, after reviewing the workflow, the answers are completely reasonable. The secret is scoped to a single step, used only for the operation that requires it, and never written to disk or echoed to the console. Other times, the review reveals that the workflow is granting far more access than it actually needs.

That’s why I don’t think of secrets as something you simply inject into a workflow and forget about. I think of them as credentials that deserve to be traced from the moment they’re introduced until the moment they’re no longer needed. Understanding that entire path often tells me much more about the security of the automation than the fact that the secret happened to be stored in GitHub Secrets.

Don’t Stop at the README

When I decide to use a third-party GitHub Action, the README is usually where I start—not where I stop. Good documentation is important, but it’s only one part of understanding the software you’re about to trust with your workflow.

After reading the documentation, I’ll usually spend a few minutes exploring the repository itself. The first thing I want to know is whether the project appears to be actively maintained.

One of the easiest ways to answer that is by cloning the repository locally:

git clone https://github.com/vendor/example-action.git

cd example-action

From there, I can review the recent commit history:

git log --oneline --decorate -10

That doesn’t tell me whether the code is secure, but it does provide some context about how actively the project is being developed.

I’ll also take a quick look at the tags and releases:

git tag

git show-ref --tags

If the project has published releases, it’s often a good indication that the maintainers have an established process for versioning their work.

Next, I’ll inspect the files that describe the project itself:

ls

I’m looking for things like:

README.md
LICENSE
SECURITY.md
CONTRIBUTING.md
action.yml

None of those files guarantee that an action is trustworthy, but together they help me understand how the project is maintained and whether the maintainers have documented expectations around reporting vulnerabilities, contributing changes, or using the action correctly.

If I plan to rely on the action for something important, I’ll often read the implementation entry point as well. The action.yml file usually tells me how GitHub will execute the action:

cat action.yml

From there I can determine whether the action runs JavaScript, executes a Docker container, or orchestrates a series of shell commands through a Composite Action.

I don’t consider any of this to be a formal security audit, nor do I think every GitHub Action requires an exhaustive source code review before it’s used. Most of the time, spending a few extra minutes understanding the repository provides enough context to make a much more informed decision.

The goal isn’t to prove that an action is completely safe—that’s an unrealistic expectation for almost any software project. The goal is simply to understand what you’re adding to your workflow, who maintains it, how actively it’s developed, and whether you’re comfortable allowing that code to execute in your environment. That’s a much more deliberate approach than copying a few lines of YAML from the first search result or AI response and assuming everything behind them has already been evaluated.

Think About GitHub Actions the Same Way You Think About Software

The biggest change in my own approach came when I stopped thinking about GitHub Actions as configuration files and started thinking about them as software. That may sound like a small distinction, but it completely changed the way I review workflows before adding them to a repository.

A workflow might look like nothing more than a YAML file:

- uses: vendor/example-action@v3

But that single line tells GitHub to download and execute code that someone else wrote. Whether that action is implemented in JavaScript, a Docker container, or a series of shell scripts doesn’t really matter. The important point is that software is about to run on your behalf.

Once I started looking at workflows through that lens, the review process became much more familiar. Instead of asking, “Does this YAML file look correct?” I found myself asking the same questions I’d ask about any other software dependency.

Who maintains this project? How active is the repository? What permissions does it request? Does it require access to secrets? Is it pinned to a specific version? What exactly is it doing during execution?

If I’m unsure about an action, it’s easy enough to inspect it myself.

git clone https://github.com/vendor/example-action.git

cd example-action

From there, I can review the metadata that tells GitHub how the action executes:

cat action.yml

If I want to understand the project a little better, I can also review the recent commit history:

git log --oneline --decorate -10

None of those commands require me to become an expert in the project. They simply help me understand what I’m introducing into my own environment.

I sometimes compare GitHub Actions to receiving a shell script from another administrator. If someone emailed me a script that downloaded additional software, authenticated with credentials I provided, and then published an application on my behalf, I wouldn’t execute it without reading through it first.

In fact, I’d probably start by opening the script in a text editor:

less deploy.sh

Or searching for commands that interact with the network or reference credentials:

grep -nE "curl|wget|token|secret|password" deploy.sh

That doesn’t mean I expect to find something malicious. It’s simply part of understanding what the script is going to do before I ask it to do it.

GitHub Actions deserve the same level of consideration. They’re packaged differently, distributed differently, and executed differently, but they’re still software running inside your development pipeline.

Once I started approaching workflows with that mindset, reviewing them became much less intimidating. I wasn’t trying to become an expert in every action I used or perform a full source code audit before every commit. I was simply applying the same habits I’d already developed for evaluating any other software that I planned to trust inside my environment. In the end, that’s really all a GitHub Action is—software that happens to be described in YAML.

Final Thoughts

GitHub Actions have become an important part of the way many of us build, test, and release software. They remove repetitive work, make build processes more consistent, and allow individuals and small teams to automate tasks that once required dedicated build servers or a significant amount of manual effort.

I use GitHub Actions regularly for everything from building applications and publishing releases to generating documentation and deploying websites. Once a workflow has been designed and validated, automation makes those processes far more repeatable than relying on someone to remember a long series of terminal commands.

That consistency is one of the biggest reasons I like GitHub Actions, but it’s also why I think it’s important to understand what they’re doing before adding them to a repository. A workflow may only be a few dozen lines of YAML, but behind those lines are actions that execute code, request permissions, access secrets, and become part of your software supply chain.

Fortunately, reviewing a workflow doesn’t have to be complicated.

If I’m evaluating a new workflow, I’ll usually start by reading the YAML from beginning to end rather than immediately committing it:

less .github/workflows/release.yml

If I see an unfamiliar action, I’ll visit the repository, clone it locally if necessary, and spend a few minutes understanding how it’s implemented:

git clone https://github.com/vendor/example-action.git

cd example-action

cat action.yml

I’ll also review the workflow itself to understand what permissions it requests, what secrets it references, and which events are capable of triggering it:

grep -nE "permissions:|secrets\.|uses:|runs-on:|on:" \
  .github/workflows/release.yml

Those few minutes of review often answer the questions that matter most. What code is going to execute? Who maintains it? What resources will it have access to? Does it actually need the permissions it’s requesting? Am I comfortable allowing it to become part of my development pipeline?

None of those questions are unique to GitHub Actions. They’re the same questions I’d ask before introducing any new software into an environment.

That’s really the perspective I hope readers take away from this discussion. The goal isn’t to distrust automation, avoid GitHub Actions, or reject workflows generated by AI. Used thoughtfully, they’re incredibly valuable tools that can save time, improve consistency, and make software development much more enjoyable.

The goal is simply to understand what you’re asking your automation to do before you trust it to do it. Once you begin treating GitHub Actions like any other software dependency, reviewing workflows becomes much more straightforward, and the decisions you make about automation become far more intentional.
