I need you to hear me out (it’s REALLY good)

If you had told me a few months ago I If you had told me a few months ago I would have to make this video, I would would have to make this video, I would would have to make this video, I would have looked at you very, very strange have looked at you very, very strange have looked at you very, very strange because I never thought I would be because I never thought I would be because I never thought I would be praising Claude code as much as I'm praising Claude code as much as I'm praising Claude code as much as I'm about to, especially in the context I'm about to, especially in the context I'm about to, especially in the context I'm about to praise it in. You see, I've about to praise it in. You see, I've about to praise it in. You see, I've been using 5-6 a lot, but I haven't been been using 5-6 a lot, but I haven't been been using 5-6 a lot, but I haven't been using it in Codex. I'm using it in using it in Codex. I'm using it in using it in Codex. I'm using it in Claude code. I'm sure you have a lot of Claude code. I'm sure you have a lot of Claude code. I'm sure you have a lot of questions as you probably should because questions as you probably should because questions as you probably should because this is kind of dumb. It is so dumb that this is kind of dumb. It is so dumb that this is kind of dumb. It is so dumb that I tried it out during my early access I tried it out during my early access I tried it out during my early access window and was impressed. And now that window and was impressed. And now that window and was impressed. And now that I'm getting more and more frustrated I'm getting more and more frustrated I'm getting more and more frustrated with Codex as a harness, a CLI and more, with Codex as a harness, a CLI and more, with Codex as a harness, a CLI and more, I decided to go explore using 5-6 soul I decided to go explore using 5-6 soul I decided to go explore using 5-6 soul in Claude code a bit more. And the in Claude code a bit more. And the in Claude code a bit more. And the results have absolutely broken me. It is results have absolutely broken me. It is results have absolutely broken me. It is not just cuz like Claude code is a not just cuz like Claude code is a not just cuz like Claude code is a better UI, it kind of is better than the better UI, it kind of is better than the better UI, it kind of is better than the Codex CLI, but the real benefits are the Codex CLI, but the real benefits are the Codex CLI, but the real benefits are the things Claude code does differently from things Claude code does differently from things Claude code does differently from how it thinks about sub-agents to its how it thinks about sub-agents to its how it thinks about sub-agents to its system prompt to its integrations and system prompt to its integrations and system prompt to its integrations and more. I already did a video where I more. I already did a video where I more. I already did a video where I praised the good parts of Claude code. I praised the good parts of Claude code. I praised the good parts of Claude code. I did not think I would be revisiting this did not think I would be revisiting this did not think I would be revisiting this topic so soon, but uh yeah, I have some topic so soon, but uh yeah, I have some topic so soon, but uh yeah, I have some issues [clears throat] with Codex. This issues [clears throat] with Codex. This issues [clears throat] with Codex. This video is going to be a bit chaotic. I'm video is going to be a bit chaotic. I'm video is going to be a bit chaotic. I'm obviously going to show you how to set obviously going to show you how to set obviously going to show you how to set up 5-6 soul in Claude code, but I also up 5-6 soul in Claude code, but I also up 5-6 soul in Claude code, but I also I'm going to talk a lot about the why, I'm going to talk a lot about the why, I'm going to talk a lot about the why, both why I'm so frustrated with Codex both why I'm so frustrated with Codex both why I'm so frustrated with Codex and also what Claude code is doing and also what Claude code is doing and also what Claude code is doing better to make me want to reach for it better to make me want to reach for it better to make me want to reach for it instead. And also a hint of why I'm not instead. And also a hint of why I'm not instead. And also a hint of why I'm not reaching for things like pie as cool as reaching for things like pie as cool as reaching for things like pie as cool as they are. No shots fired at pie at all, they are. No shots fired at pie at all, they are. No shots fired at pie at all, but I really need to focus in on Claude but I really need to focus in on Claude but I really need to focus in on Claude code and Codex because there is a new code and Codex because there is a new code and Codex because there is a new generation of capability with these

generation of capability with these generation of capability with these models and it is very, very important models and it is very, very important models and it is very, very important that we understand what these harnesses that we understand what these harnesses that we understand what these harnesses are doing right and wrong if we want to are doing right and wrong if we want to are doing right and wrong if we want to get the most out of them. But first, I get the most out of them. But first, I get the most out of them. But first, I want to make sure you get the most out want to make sure you get the most out want to make sure you get the most out of today's sponsor. AI has gotten really of today's sponsor. AI has gotten really of today's sponsor. AI has gotten really good at writing code and it's even good at writing code and it's even good at writing code and it's even gotten decent at reviewing code. So why gotten decent at reviewing code. So why gotten decent at reviewing code. So why is it that code review has never been is it that code review has never been is it that code review has never been worse? I'm so tired of just going worse? I'm so tired of just going worse? I'm so tired of just going through these PRs. Like look at this. through these PRs. Like look at this. through these PRs. Like look at this. Why is it an alphabetical list of files Why is it an alphabetical list of files Why is it an alphabetical list of files in my code base? This PR has a thousand in my code base? This PR has a thousand in my code base? This PR has a thousand lines changed. Are you seriously going lines changed. Are you seriously going lines changed. Are you seriously going to tell me I have to sit here and go to tell me I have to sit here and go to tell me I have to sit here and go through every single one of them? through every single one of them? through every single one of them? Wouldn't it be nicer if this was broken Wouldn't it be nicer if this was broken Wouldn't it be nicer if this was broken up based on what's actually happening up based on what's actually happening up based on what's actually happening and not the order of the code in the and not the order of the code in the and not the order of the code in the code base? It'd be really cool if one of code base? It'd be really cool if one of code base? It'd be really cool if one of our code review agents could do this our code review agents could do this our code review agents could do this breaking up for us and give us a way breaking up for us and give us a way breaking up for us and give us a way better interface to review our code in, better interface to review our code in, better interface to review our code in, wouldn't it? Oh, it's open, isn't it? wouldn't it? Oh, it's open, isn't it? wouldn't it? Oh, it's open, isn't it? Surprise, Code Rabbit has a code review Surprise, Code Rabbit has a code review Surprise, Code Rabbit has a code review platform now, not just a GitHub plugin, platform now, not just a GitHub plugin, platform now, not just a GitHub plugin, but an actual full website that is way but an actual full website that is way but an actual full website that is way easier to read changes from. They break easier to read changes from. They break easier to read changes from. They break up the PR into different layers, which up the PR into different layers, which up the PR into different layers, which describe specific changes that the PR describe specific changes that the PR describe specific changes that the PR makes, making it way easier to review.

Each of these sections is a summary and Each of these sections is a summary and Each of these sections is a summary and the details that are important called the details that are important called the details that are important called out, and the pieces inside of the layer out, and the pieces inside of the layer out, and the pieces inside of the layer are prioritized based on what you should are prioritized based on what you should are prioritized based on what you should be caring about. They even have fancy be caring about. They even have fancy be caring about. They even have fancy little guides on the side here that show little guides on the side here that show little guides on the side here that show us labeled sections that might be worth us labeled sections that might be worth us labeled sections that might be worth checking out. This is particularly checking out. This is particularly checking out. This is particularly useful on gigantic PRs because they're useful on gigantic PRs because they're useful on gigantic PRs because they're basically impossible to use in the basically impossible to use in the basically impossible to use in the GitHub interface. Since this one breaks GitHub interface. Since this one breaks GitHub interface. Since this one breaks things up, it's way easier to find the things up, it's way easier to find the things up, it's way easier to find the parts that actually matter and give parts that actually matter and give parts that actually matter and give useful feedback to your team.

So, with that, let's get started with uh So, with that, let's get started with uh So, with that, let's get started with uh what's wrong with Codex? There are what's wrong with Codex? There are what's wrong with Codex? There are layers to this one. I don't want to layers to this one. I don't want to layers to this one. I don't want to crash out again about the rebranding of crash out again about the rebranding of crash out again about the rebranding of Codex as the Chachi BT desktop app or Codex as the Chachi BT desktop app or Codex as the Chachi BT desktop app or about the [ __ ] show of the CLI not about the [ __ ] show of the CLI not about the [ __ ] show of the CLI not getting updated as much as the desktop getting updated as much as the desktop getting updated as much as the desktop app. app. app. Generally speaking, I still think for Generally speaking, I still think for Generally speaking, I still think for most people, the best way to start using most people, the best way to start using most people, the best way to start using and taking advantage of more agentic and taking advantage of more agentic and taking advantage of more agentic engineering is the Codex desktop app on engineering is the Codex desktop app on engineering is the Codex desktop app on one of the Codex subscriptions. This one of the Codex subscriptions. This one of the Codex subscriptions. This hurts because obviously, I want to be hurts because obviously, I want to be hurts because obviously, I want to be pushing people towards T3 Code, but the pushing people towards T3 Code, but the pushing people towards T3 Code, but the Codex app is a really good starting Codex app is a really good starting Codex app is a really good starting point. So much so that it inspired me to point. So much so that it inspired me to point. So much so that it inspired me to build my own open-source alternative, build my own open-source alternative, build my own open-source alternative, but I have some issues right now. The but I have some issues right now. The but I have some issues right now. The biggest issue by far is how Codex thinks biggest issue by far is how Codex thinks biggest issue by far is how Codex thinks about sub-agents. I just filmed a video about sub-agents. I just filmed a video about sub-agents. I just filmed a video about Ultra mode that's already out. I about Ultra mode that's already out. I about Ultra mode that's already out. I would recommend checking that if you would recommend checking that if you would recommend checking that if you want a deeper dive on this. The simplest want a deeper dive on this. The simplest want a deeper dive on this. The simplest TLDR I can give is that there's two TLDR I can give is that there's two TLDR I can give is that there's two versions of sub-agents in Codex. The V1 versions of sub-agents in Codex. The V1 versions of sub-agents in Codex. The V1 is stable and very simple. It lets the

is stable and very simple. It lets the is stable and very simple. It lets the top-level agent spawn a bunch of top-level agent spawn a bunch of top-level agent spawn a bunch of sub-agents one level deeper with sub-agents one level deeper with sub-agents one level deeper with specific work and tasks to do and then specific work and tasks to do and then specific work and tasks to do and then gets a response when they're done. V2, gets a response when they're done. V2, gets a response when they're done. V2, which is the new unfinished version that which is the new unfinished version that which is the new unfinished version that you have to manually enable, has the you have to manually enable, has the you have to manually enable, has the ability to copy the whole context window ability to copy the whole context window ability to copy the whole context window over by default, which is annoying, and over by default, which is annoying, and over by default, which is annoying, and also let the sub-agents spin up their also let the sub-agents spin up their also let the sub-agents spin up their own named sub-agents beneath them with own named sub-agents beneath them with own named sub-agents beneath them with layering and message passing between layering and message passing between layering and message passing between them. It takes a very simple hierarchy them. It takes a very simple hierarchy them. It takes a very simple hierarchy and makes it a bit absurdly complex and and makes it a bit absurdly complex and and makes it a bit absurdly complex and adds a ton of tools that are necessary adds a ton of tools that are necessary adds a ton of tools that are necessary for all of these things to communicate, for all of these things to communicate, for all of these things to communicate, and the result's a bit chaotic and and the result's a bit chaotic and and the result's a bit chaotic and clearly still being tuned. That's why clearly still being tuned. That's why clearly still being tuned. That's why it's off by default. Go check out my it's off by default. Go check out my it's off by default. Go check out my video I just did about Ultra if you want video I just did about Ultra if you want video I just did about Ultra if you want a deeper dive on how sub-agents are a deeper dive on how sub-agents are a deeper dive on how sub-agents are currently working in Codex. The thing I currently working in Codex. The thing I currently working in Codex. The thing I want you to know right now is that I want you to know right now is that I want you to know right now is that I don't like it and I find that the don't like it and I find that the don't like it and I find that the sub-agent workflows, specifically the sub-agent workflows, specifically the sub-agent workflows, specifically the workflow feature in Claude code, is much workflow feature in Claude code, is much workflow feature in Claude code, is much better. Because instead of having better. Because instead of having better. Because instead of having sub-agents spawn randomly when the model sub-agents spawn randomly when the model sub-agents spawn randomly when the model decides to, the model will upfront decides to, the model will upfront decides to, the model will upfront define a programmatic workflow with define a programmatic workflow with define a programmatic workflow with different stages, different prompts, different stages, different prompts, different stages, different prompts, different sub-agents at each stage that different sub-agents at each stage that different sub-agents at each stage that can spawn work for other stages, all in can spawn work for other stages, all in can spawn work for other stages, all in a single JavaScript file that is a single JavaScript file that is a single JavaScript file that is executed top to bottom because code is a executed top to bottom because code is a executed top to bottom because code is a great way to define something dynamic.

great way to define something dynamic. great way to define something dynamic. Since workflows are code, they actually Since workflows are code, they actually Since workflows are code, they actually end, which I have found to be a huge win end, which I have found to be a huge win end, which I have found to be a huge win for token efficiency when using the 5-6 for token efficiency when using the 5-6 for token efficiency when using the 5-6 models. They tend to just kind of go models. They tend to just kind of go models. They tend to just kind of go forever with Ultra, and I have seen way, forever with Ultra, and I have seen way, forever with Ultra, and I have seen way, way less utilization on my limits when way less utilization on my limits when way less utilization on my limits when I'm doing this through workflows I'm doing this through workflows I'm doing this through workflows instead, even for the same task. Ultra instead, even for the same task. Ultra instead, even for the same task. Ultra can just go forever, workflows won't. can just go forever, workflows won't. can just go forever, workflows won't. The output quality's the same if not The output quality's the same if not The output quality's the same if not better from workflows, and the token better from workflows, and the token better from workflows, and the token usage is like a fourth as much. So, much usage is like a fourth as much. So, much usage is like a fourth as much. So, much more efficient way of doing things. more efficient way of doing things. more efficient way of doing things. OpenAI is shipping the code in Codex OpenAI is shipping the code in Codex OpenAI is shipping the code in Codex itself, and the model has to call the itself, and the model has to call the itself, and the model has to call the code correctly. Claude Code lets the code correctly. Claude Code lets the code correctly. Claude Code lets the model itself write the code for its model itself write the code for its model itself write the code for its workflow and for its sub-agents, which I workflow and for its sub-agents, which I workflow and for its sub-agents, which I have found to be much better overall. I have found to be much better overall. I have found to be much better overall. I found it to be so much better that I found it to be so much better that I found it to be so much better that I wanted to try it myself, and that's what wanted to try it myself, and that's what wanted to try it myself, and that's what inspired me initially to start using 5-6 inspired me initially to start using 5-6 inspired me initially to start using 5-6 inside of Claude Code. Not Fable in inside of Claude Code. Not Fable in inside of Claude Code. Not Fable in Claude Code calling 5-6 over the Codex Claude Code calling 5-6 over the Codex Claude Code calling 5-6 over the Codex CLI, but with 5-6 is the actual model CLI, but with 5-6 is the actual model CLI, but with 5-6 is the actual model doing the work in Claude Code itself. doing the work in Claude Code itself. doing the work in Claude Code itself. Since then, I've been using it a ton. Since then, I've been using it a ton. Since then, I've been using it a ton. And the more I use it, the more And the more I use it, the more And the more I use it, the more impressed I get. I have a question for impressed I get. I have a question for impressed I get. I have a question for you guys. Which model do you think you guys. Which model do you think you guys. Which model do you think designed this page?

designed this page? designed this page? When I look at this, it screams Claude When I look at this, it screams Claude When I look at this, it screams Claude to me. to me. to me. This obviously looks like something that This obviously looks like something that This obviously looks like something that Claude made, right? Like Fable or Opus. Claude made, right?

As someone who's looked at a lot of pages that were generated with lot of pages that were generated with lot of pages that were generated with Codex, Codex, Codex, it could be something GLM or otherwise it could be something GLM or otherwise it could be something GLM or otherwise distilled off of Claude, but this distilled off of Claude, but this distilled off of Claude, but this screams Claude to me. For reference, screams Claude to me. For reference, screams Claude to me. For reference, here's a similar page I did with Codex here's a similar page I did with Codex here's a similar page I did with Codex in 5-6 Soul. I don't know about you in 5-6 Soul. I don't know about you in 5-6 Soul. I don't know about you guys, but the difference in quality here guys, but the difference in quality here guys, but the difference in quality here is pretty aggressive to me. is pretty aggressive to me. is pretty aggressive to me. I think both are slop, to be clear. I think both are slop, to be clear. I think both are slop, to be clear. This one hurts me a lot less than the This one hurts me a lot less than the This one hurts me a lot less than the one that Codex did. one that Codex did. one that Codex did. It shouldn't be too surprising to you, It shouldn't be too surprising to you, It shouldn't be too surprising to you, based on the topic of this video, that based on the topic of this video, that based on the topic of this video, that this page was made with Soul inside of this page was made with Soul inside of this page was made with Soul inside of Claude Code. Claude Code. Claude Code. So, why the hell is 5-6 Soul making So, why the hell is 5-6 Soul making So, why the hell is 5-6 Soul making designs this much better in Claude Code? designs this much better in Claude Code? designs this much better in Claude Code? You probably are going to have the same You probably are going to have the same You probably are going to have the same assumption I had, which is that they assumption I had, which is that they assumption I had, which is that they have some things in the system prompt have some things in the system prompt have some things in the system prompt for Claude Code that make it more likely for Claude Code that make it more likely for Claude Code that make it more likely to do good designs.

to do good designs. to do good designs. So, I investigated. I read the full So, I investigated. I read the full So, I investigated. I read the full Claude Code system prompt, trying to Claude Code system prompt, trying to Claude Code system prompt, trying to find this front-end guidance so that I find this front-end guidance so that I find this front-end guidance so that I could bring it over to Codex and maybe could bring it over to Codex and maybe could bring it over to Codex and maybe have Codex design better. So, I hunted, have Codex design better. So, I hunted, have Codex design better. So, I hunted, and the word front-end appears three and the word front-end appears three and the word front-end appears three times. First, it appears with the times. First, it appears with the times. First, it appears with the instructions that for UI and front-end instructions that for UI and front-end instructions that for UI and front-end changes, start the dev server and use changes, start the dev server and use changes, start the dev server and use the features in a browser before the features in a browser before the features in a browser before reporting the task as complete.

Why is it designing things so much Why is it designing things so much Why is it designing things so much better then? Something has to be up. I better then? Something has to be up. I better then? Something has to be up. I also remember that OpenAI has been also remember that OpenAI has been also remember that OpenAI has been bragging about 5.6 being way better at bragging about 5.6 being way better at bragging about 5.6 being way better at design even though I never saw that. But design even though I never saw that. But design even though I never saw that. But when I was testing 5.6, almost all of when I was testing 5.6, almost all of when I was testing 5.6, almost all of the work I did in it was done in Codex.

One last thing before we do the setup though, I want to talk do the setup though, I want to talk do the setup though, I want to talk about the gotchas that I've been about the gotchas that I've been about the gotchas that I've been experiencing using Codex models inside experiencing using Codex models inside experiencing using Codex models inside of Claude code. Admittedly, there have of Claude code. Admittedly, there have of Claude code. Admittedly, there have been fewer than I expected. First off, been fewer than I expected. First off, been fewer than I expected. First off, I've noticed it sometimes loses track of I've noticed it sometimes loses track of I've noticed it sometimes loses track of what it's doing a little bit more. This what it's doing a little bit more. This what it's doing a little bit more. This could be changes in how context is could be changes in how context is could be changes in how context is managed, but I honestly think this is managed, but I honestly think this is managed, but I honestly think this is just something small in the system just something small in the system just something small in the system prompt. Here is an example where I had prompt. Here is an example where I had prompt. Here is an example where I had it making changes alongside two other it making changes alongside two other it making changes alongside two other agents. All three were making HTML files agents. All three were making HTML files agents. All three were making HTML files for me to go review the feedback it was for me to go review the feedback it was for me to go review the feedback it was giving.

giving. giving. And two of them happened to come up with And two of them happened to come up with And two of them happened to come up with the same name for the HTML file. One was the same name for the HTML file. One was the same name for the HTML file. One was using Fable and it wrote fine and made using Fable and it wrote fine and made using Fable and it wrote fine and made the URL fine. the URL fine. the URL fine. This one was using 56 Soul This one was using 56 Soul This one was using 56 Soul and it tried to write the file. and it tried to write the file. and it tried to write the file. It already existed, so it said it would It already existed, so it said it would It already existed, so it said it would leave that file untouched and publish a leave that file untouched and publish a leave that file untouched and publish a new report with a distinct file name. new report with a distinct file name. new report with a distinct file name. So, it did its own different file So, it did its own different file So, it did its own different file instead. instead. instead. Of note though is that I told it to use Of note though is that I told it to use Of note though is that I told it to use my HTML plan skill. And my HTML plan my HTML plan skill. And my HTML plan my HTML plan skill. And my HTML plan skill explicitly tells the model skill explicitly tells the model skill explicitly tells the model to use the web host through the CLI I to use the web host through the CLI I to use the web host through the CLI I gave it to host this model. This skill gave it to host this model. This skill gave it to host this model. This skill is meant to give the model the ability is meant to give the model the ability is meant to give the model the ability to upload the HTML with a link that I to upload the HTML with a link that I to upload the HTML with a link that I can click and look at. It's one of my can click and look at. It's one of my can click and look at. It's one of my favorite things I've built, my silly favorite things I've built, my silly favorite things I've built, my silly little post plan site. And it even says little post plan site. And it even says little post plan site. And it even says here, I'll keep it standalone and here, I'll keep it standalone and here, I'll keep it standalone and responsive, then publish through post responsive, then publish through post responsive, then publish through post plan as requested. plan as requested. plan as requested. It failed to write. It noticed the file It failed to write. It noticed the file It failed to write. It noticed the file already existed. It made the new file. already existed. It made the new file. already existed. It made the new file. Oh, wait. I was wrong. I thought it Oh, wait. I was wrong. I thought it Oh, wait. I was wrong. I thought it didn't host it. This is a link. It's didn't host it. This is a link. It's didn't host it. This is a link. It's just not familiar with the formatting just not familiar with the formatting just not familiar with the formatting here. I'm used to the model spitting out here. I'm used to the model spitting out here. I'm used to the model spitting out an actual link. This is somehow a an actual link. This is somehow a an actual link. This is somehow a clickable link even though it doesn't clickable link even though it doesn't clickable link even though it doesn't look like that here at all. I was wrong.

look like that here at all. I was wrong. look like that here at all. I was wrong. I thought it just didn't do that step. I thought it just didn't do that step. I thought it just didn't do that step. It did. I asked it and here it gave me It did. I asked it and here it gave me It did. I asked it and here it gave me the actual link in text that makes more the actual link in text that makes more the actual link in text that makes more sense. sense. sense. I was wrong about that. Mostly it's good I was wrong about that. Mostly it's good I was wrong about that. Mostly it's good about these things. Like it does about these things. Like it does about these things. Like it does stay on task largely fine. It just stay on task largely fine. It just stay on task largely fine. It just doesn't know how to use the formatting doesn't know how to use the formatting doesn't know how to use the formatting great. And I have noticed this in other great. And I have noticed this in other great. And I have noticed this in other places, too. Like here when it did the places, too. Like here when it did the places, too. Like here when it did the number-based formatting, it screwed it number-based formatting, it screwed it number-based formatting, it screwed it up a little bit. Like here it's number up a little bit. Like here it's number up a little bit. Like here it's number one, it's heavily coupled to one one, it's heavily coupled to one one, it's heavily coupled to one specific runtime. Has a chunk and then specific runtime. Has a chunk and then specific runtime. Has a chunk and then one again, modern models generally one again, modern models generally one again, modern models generally understand yada yada. Then it has two understand yada yada. Then it has two understand yada yada. Then it has two twice, then it has three twice, and then twice, then it has three twice, and then twice, then it has three twice, and then four twice. I think there's something four twice. I think there's something four twice. I think there's something weird about how markdown formatting weird about how markdown formatting weird about how markdown formatting works in Claude code, but works in Claude code, but works in Claude code, but 5-6 isn't doing it right, clearly. 5-6 isn't doing it right, clearly. 5-6 isn't doing it right, clearly. Remember, the reason I wanted to do this Remember, the reason I wanted to do this Remember, the reason I wanted to do this initially was for ultra code and initially was for ultra code and initially was for ultra code and specifically for workflows, because I specifically for workflows, because I specifically for workflows, because I wanted to see how good 5-6 could do wanted to see how good 5-6 could do wanted to see how good 5-6 could do workflows. workflows. workflows. And it does them great. There was a And it does them great. There was a And it does them great. There was a problem, though. It is an append to the problem, though. It is an append to the problem, though. It is an append to the system prompt that says, "Hey, please system prompt that says, "Hey, please system prompt that says, "Hey, please please please use workflows for this please please use workflows for this please please use workflows for this task." This works great with Claude task." This works great with Claude task." This works great with Claude models. You can tell it to use them for models. You can tell it to use them for models. You can tell it to use them for your workflows and orchestration. For your workflows and orchestration. For your workflows and orchestration. For example, here I told it that I want to example, here I told it that I want to example, here I told it that I want to better understand this code base. It's better understand this code base. It's better understand this code base. It's the Codex code base, and I want it to the Codex code base, and I want it to the Codex code base, and I want it to analyze with a workflow. Use 5 6 Soul, 5 analyze with a workflow. Use 5 6 Soul, 5 analyze with a workflow. Use 5 6 Soul, 5 6 Terra, and Fable 5 all on high 6 Terra, and Fable 5 all on high 6 Terra, and Fable 5 all on high reasoning levels to analyze the code reasoning levels to analyze the code reasoning levels to analyze the code base. I want it to have the info when I base. I want it to have the info when I base. I want it to have the info when I ask it a vague thing like this so that ask it a vague thing like this so that ask it a vague thing like this so that it will orchestrate properly. So, I'll it will orchestrate properly. So, I'll it will orchestrate properly. So, I'll probably put it in my system prompt in probably put it in my system prompt in probably put it in my system prompt in some way or my global agents MD. There's some way or my global agents MD. There's some way or my global agents MD. There's a lot of places you can put it, but as a lot of places you can put it, but as a lot of places you can put it, but as long as you give Claude code the ability long as you give Claude code the ability long as you give Claude code the ability to know what you mean by Soul Terra and

to know what you mean by Soul Terra and to know what you mean by Soul Terra and other things, or you just specify them other things, or you just specify them other things, or you just specify them correctly here, you're good to go. correctly here, you're good to go. correctly here, you're good to go. There's a couple other small catches. There's a couple other small catches. There's a couple other small catches. Like for example, here the 5 6 models Like for example, here the 5 6 models Like for example, here the 5 6 models don't report how many tokens they're don't report how many tokens they're don't report how many tokens they're using until the work is done. Fable will using until the work is done. Fable will using until the work is done. Fable will give you live updates about how many give you live updates about how many give you live updates about how many tokens it's using. It's a small thing, tokens it's using. It's a small thing, tokens it's using. It's a small thing, just one of the few I noticed. Overall, just one of the few I noticed. Overall, just one of the few I noticed. Overall, I've actually been really impressed with I've actually been really impressed with I've actually been really impressed with this. this. this. And I already see the comments coming And I already see the comments coming And I already see the comments coming in, in, in, so I'm going to address them now. so I'm going to address them now. so I'm going to address them now.

They're sure their system prompts are less bad than their system prompts are less bad than their system prompts are less bad than Codex is, but they don't solve the sub Codex is, but they don't solve the sub Codex is, but they don't solve the sub agent orchestration problem, which is agent orchestration problem, which is agent orchestration problem, which is the thing I am most excited about here. the thing I am most excited about here. the thing I am most excited about here.

Pi is great, but you're going to have to build all of these going to have to build all of these going to have to build all of these workflows and orchestration tools workflows and orchestration tools workflows and orchestration tools yourself. Open code has a bunch of yourself. Open code has a bunch of yourself.

The workflows in Claude Code workflows. The workflows in Claude Code workflows. The workflows in Claude Code are the best implementation I have seen are the best implementation I have seen are the best implementation I have seen of orchestrating sub-agents on real of orchestrating sub-agents on real of orchestrating sub-agents on real day-to-day work for people who are day-to-day work for people who are day-to-day work for people who are employed that I've ever seen, by far.

If you want to have an agent break up other you want to have an agent break up other you want to have an agent break up other agents with other models to do complex agents with other models to do complex agents with other models to do complex work, to take turns and have phases work, to take turns and have phases work, to take turns and have phases throughout, to kick off things that throughout, to kick off things that throughout, to kick off things that matter and ignore things that don't, and matter and ignore things that don't, and matter and ignore things that don't, and have an actual end, have an actual end, have an actual end, workflows are the best solution I have workflows are the best solution I have workflows are the best solution I have found for this by far.

In fact, Codex told me to just add it to In fact, Codex told me to just add it to In fact, Codex told me to just add it to Codex myself when I asked it about that Codex myself when I asked it about that Codex myself when I asked it about that versus using it in Claude Code. You can versus using it in Claude Code. You can versus using it in Claude Code. You can absolutely do this.

absolutely do this. absolutely do this. That all said, Claude Code has this That all said, Claude Code has this That all said, Claude Code has this figured out. They have a good system for figured out. They have a good system for figured out. They have a good system for it built in. They have good UI built for it built in.
