The playbook, distilled

It is a framework, not a product

ECC is Affaan Mustafa's performance-optimization layer for the Claude Code agent harness, built over 10+ months of daily use. You take it and tailor it to your own workflow.

What you actually install

On load the walkthrough reports 9 plugins, 75 skills, 71 agents, 33 hooks, and 8 plugin MCP servers.

Two-step setup

Step 1: add the marketplace, then install the plugin at user scope and reload. Step 2: rules cannot ship through plugins, so clone the repo, run npm install, and install the full (or per-language) profile, which also wires up the MCP servers in mcp.json.

Plan-first, confirmation-gated

Running a workflow loads a plan skill that builds a thorough plan and then waits for your explicit confirmation before it writes anything. You pick the approach (for example pop-up vs new tab) before code happens.

Test-driven by default

Asked to follow test-driven development, it set up the testing harness, wrote tests first, generated six passing tests, and aimed for ~80% coverage before shipping the feature.

Built-in security scan

A security agent (the speaker's 'Shield' tool from the hackathon) graded the project A, 97/100, with two non-critical findings.

Who it's for

New to agentic coding: spin up a home project, load the marketplace plugins, and experiment. Experienced: you have everything to ship real products fast.

0:00Everything Cloud Code as of now is the most popular GitHub repo about Cloud Code.
0:04It got more than 120k GitHub stars. It contains a lot of skills, agents, commands,
0:10and also a brilliant practical guidance how to use all of that.
0:13In this video, I walk you through all of this stuff and show how to easily get started.
0:17If that sounds good, let's go into that.
0:20All right, Everything Cloud Code. That is why we're here.
0:24Look at this number. 127k GitHub stars. It's insane.
0:29So the creator is Phan Mustafa. And who is this guy?
0:33It is Antropic Hecton winner. And he created the performance optimization system for AI
0:39agent harness. I would say it's even a framework because if you look into what is inside,
0:47it's like look at this number of agents, skills, commands, rules, hooks.
0:56So I would say that you can just get it and tailor it to whatever development workflow you
1:05currently have. To get started, we need just follow this quick start section.
1:10So the step one is going to be install the plugin. For that, I need to write my cloud.
1:15And actually, before installing the plugin, we need to install Marketplace, as mentioned here.
1:19Let's just add this Marketplace. All right, we've got a successfully added Marketplace.
1:24Everything Cloud Code. So after that, we are ready to install plugin. Let's go for it.
1:31And I want to add it on the user scope. Okay, we can reload plugins right now.
1:38And they should appear. All right, we've got nine plugins, 75 skills, 71 agent,
1:4533 hooks, eight plugin MCP servers. Great. Let's exit. Let's follow the step two.
1:53Install rules required. Cloud Code plugins cannot distribute rules automatically. Install them
1:58manually. So for doing that, we need to clone GitHub repository of everything Cloud Code.
2:06Let's do it. Just get it. Go to this folder and run npm install to install packages.
2:16If you use different package manager, run your command. And after that, we can install
2:25full profile or for specific languages. I would go with full profile, but make a choice here.
2:33So writing this command, the script, added basically everything that I need. Let's run
2:40Cloud again. And as you can see, we prompted that six new MCP servers found in mcp.json.
2:50I want to leave all of them right now, because these are new MCP services that we just added.
2:56Let's go for it. And when we run slash everything Cloud Code, I see that I've got a lot of things
3:04to do here. I know that you're here for real world examples, so let's use our plugin and build a new
3:11feature for my personal website. I want to add in header a button called schedule meeting with me.
3:18And the logic that it should open a calendar and allow my visitors to make a Google meet.
3:24If I go back to everything Cloud Code repo, I do have common workflows here. And I just want
3:31to follow workflow and see what happens. So if I copy this command and make a start and say,
3:40hey, I want you to implement a new feature for my personal website. In header section,
3:46we need to add schedule meeting button and it should open calendar and allow my visitors
3:54to schedule a meeting with me. Can you help to plan that and implement after all? Yeah,
4:01let's see how it goes. So as we can see, a skill plan successfully loaded. Not sure what is
4:09P2 skill hook error, why it's happened, but let's discard that for now. Yeah, and as we can see,
4:15the skill already started working. Wow, just 44 seconds. Great. Now I have everything I need
4:22to create a thorough plan. So it has everything right now. Good. It is requirements, head schedule
4:29meeting button, approach option, calendar pop-up widget, or direct calendar link. It recommends
4:35this thing. I agree with that. Then basically about implementation plan, complexity law. All right.
4:46But before I proceed, which approach do you prefer? Pop-up model or new tab link. I would
4:52go with the pop-up model. And then what is your current URL? And the button label will be
5:01schedule meeting and the position. Good question. So it should appear to the left. So what is cool
5:12here that it weights your confirmation. You just need to explicitly tell that you want to proceed.
5:18I think I'm good, but I just want it to follow that driven development approach. Great. Follow.
5:27Okay. Let's kick it off. So it's loaded to the skill. Let me check the testing setup first.
5:34To be honest, I don't have testing setup because I do only have front end here. Okay. So it just
5:41said that, right? So it wants to install dependencies. Wow. Actually, actually it is
5:51much better because it starts to set up just for testing. Brilliant. So yeah, actually,
6:01I'm super impressed that now I'll have tests. Let's go, baby. Wow. Okay. So we've got just
6:14so, yeah, this is tests. And as we can see, it's created tests before created and generated. And
6:23you could, okay, so we get six tests and they all pass just briefly. Let's see what
6:31tests are. So it renders a schedule meeting button and renders the connect with me link
6:38schedule meeting button appears before connect with me in the dome.
6:43Calendium model is not visible by default. All right. So pretty comprehensive tests. That's great.
6:52And obviously it adds some points to stability of my website. It aims to cover 80%. So it adds
7:04just much more tests. And this is good. To be honest, AI is really good in writing tests.
7:11I stopped writing tests like one year ago. So I just generate them all the time. I guess we can
7:19just test it, right? So we get this button schedule meeting. And yeah, it opens Calendium for me.
7:27So it looks at my calendar and yeah, whatever dates, for example, tomorrow, I'm free after 6pm.
7:38Name, for example, like Maria, some email example that Gmail.com. And let's schedule this event.
7:50All right. So it should work. Brilliant. So we got it. We got it. We got one more extra feature to
7:57my website. Let's verify it. So if I go to my calendar, I see that I've got this meeting,
8:06right? So yeah, everything works as expected. But let's just run this also commands to see
8:14what is the output. So if I want to do security scan, can I do that? So it uses this agent shield
8:27product. Let's try it. So the agent shield product, as I mentioned before, it is something that
8:34this guy created on that entropic hackathon. So yeah, it's interesting. Grade A, 97 out of 100,
8:44the project configuration is in good shape. So two findings, neither critical. So what you can do right
8:50now, if you just get started with agenda coding, I would recommend to kick off your home project
8:57and load this marketplace plugins and experiment with that achieve your result, build something.
9:04If you experienced a developer, you have all instruments to deliver a real world products
9:09quickly right now. Don't lose the chance. Give a like if this video is something useful for you.
9:15Also drop your comment if you have any opinion. I read all of them. Also, if you're interested in
9:21cloud cloud topic, I recently released a video about my cloud cloud learnings. So it should
9:26appear somewhere here and misses. And yeah, let's just continue building the AI and see you in the
9:31next one. Bye.
