Your OpenClaw AI Agent Is Ignoring Half Its Instructions 18,000 Character Trap

Added: 2026-05-08

[00:00:00]Your open claw agent is skipping half of its own instructions and you have absolutely no idea. If you've ever wondered why your agent keeps making the same mistake even though you wrote a rule about it or why it ignores part of its soul.md file. This is the reason.

[00:00:17]It's not the agent's fault. It's a hard coded limit nobody talks about at all.

[00:00:21]My name is Andrew. I run 11 AI agents across three businesses two of which are seven figure businesses and I've logged over 700 hours building inside Open Claw at this point and I took my AI agency to multiple five figures without hiring a single human employee. This is the Open Claw blueprint. This is video two of eight in the Open Claw blueprint series and today we're breaking down the 18,000 character trap. Now let me ask you something. Have you ever written a rule in your agent's soul.md file and then watched it completely ignore that rule?

[00:00:55]I would assume yes. Have you ever added more context, more instructions, more examples hoping it would finally stick and instead the agent just got worse?

[00:01:05]Yeah, I would assume so because it's happened to me as well.

[00:01:09]And have you ever wondered if maybe Open Claw just doesn't work the way that you see other YouTubers said it would? You probably have. Now it's not Open Claw, it's not your agent, it's the way you're feeding it information. Here's what was happening to me. I had a soul.md file that I was really, really proud of and I had written everything I wanted my agent to know, personality role, escalation rules, examples of how to handle different situations, that, the whole thing, like the entire thing. It was probably 28,000 characters of just pure gold and the agent kept failing. It kept missing rules I had clearly written down. I'd point to the file and say it's right there. Why aren't you following this? And the agent would respond like it had never even seen that part of the file in the first place. And here's why this matters. If you're running Open Claw and you don't know about this limit, you're wasting tokens on every single session. You're paying for context the agent literally cannot see.

[00:02:04]Every dollar you spend on usage is partially going to instructions your agent is completely skipping and if you're running multiple agents like I am, that cost compounds so fast. So I wasn't going to accept that. So I dug into the documentation. I tested the limit myself across multiple agents and I finally figured out exactly what's happening under the hood. Now really quick, if you guys get any value out of this video or any of the videos on my channel or in this Open Claw blueprint series, I need you to go ahead and join our Telegram. It is free, completely free, nothing to sell you. The link is down in the description below where business owners and beginners are actually implementing this stuff and are actually having influence over what I make here content wise on YouTube and what I cover in live streams every Tuesday and Thursday. So if you want influence on that, go ahead and click the link down in the description below.

[00:02:56]You can join the Telegram. Again, completely free, absolutely nothing to sell you. Now here's what I want you to understand. This isn't a bug. This is how Open Claw is designed to work and once you understand how it actually reads your files, you stop fighting the system and you actually start working with it. So here's what's actually happening. Open Claw has a hard character limit on how much of a single file it will read. That number is 18,000 characters, not words, characters, including like spaces, line breaks, punctuation, all that good stuff, right?

[00:03:27]And if your file goes over 18,000 characters, Open Claw doesn't even tell you. It doesn't throw any errors. It doesn't warn you. It just quietly truncates whatever it won't read. And this is the part that really broke my brain when I first figured this out. It doesn't read the first 18,000 characters and then stop. It reads the first 14,000 characters on your file. Then it skips the entire middle and then it reads the last 4,000 characters inside of that file. So if your soul.md file is 28,000 characters, your agent is reading the beginning, skipping 10,000 characters in the middle and picking back up at the end. Whatever lives in the middle of that section, your agent literally never sees. Now think about what that means for the way most people write soul.md files. They put the agent's identity at the top, the role and personality near the top as well, the escalation rules and detailed examples in the middle and then they wrap up with a summary and some final instructions at the bottom.

[00:04:26]So your agent reads the identity, it reads their role, skips all the detailed examples and edge cases, then reads your closing notes. And you're sitting there wondering why the agent keeps screwing up the exact scenarios you wrote rules for. That's because at the end of the day, it never, ever reads those rules.

[00:04:46]And this isn't a bug. It's actually a smart design choice. Long files cost more tokens to process and by reading the head and the tail of a long file, Open Claw protects you from runaway costs. The problem is is that most people don't even know it works this way. So they write files that suffer the most from truncation. So here's the rule. Every single critical file you write for an Open Claw agent stays under 18,000 characters. Soul.md, agents.md, any of them to be honest. If they go over, you're losing the entire middle of that file. Now if you're getting a lot of value from this, then go ahead and do me a favor and give me a follow on X.

[00:05:25]Okay, the link is down in the description below. That's where a lot of people have been directly DMing me and that is the best place to get some direct help to some of the questions you have other than in the comment section below. So if you're getting any value from this, then go ahead and links in the description to go ahead and give me a follow on X. So now you know the limit. The question is, how do you fit everything you need into 18,000 characters when there's clearly more to say? Well, there are four techniques I use across all the 11 of my agents and once I locked these in, my files dropped from like 25,000 plus characters to under 16,000 and my agents performance literally jumped immediately. That is no exaggeration. Technique number one is just write dense, okay? Every word matters. This is not a place for fillers. Most people write soul.md files like they're writing a college essay, okay? Long sentences, soft transitions, repeating themselves with slight variations. I know because I do this a lot and just cut all of it, okay? If you can say something in five words instead of 15, say it in five. The bad version of this would be, it is important that you remember to always include the at mention when you respond to another agent in the workspace. That's an example of a bad way to go about it. Now the good way to go about it is just always include at mention whenever responding to agents. Same instructions, a third of the characters. Your agent gets the same rule and you just saved 11,000 characters across the file. Now I will say that in order for you to do this most optimally, you should just go in and ask your agent to read the file, tell you how many characters it is and then absolutely eliminate any of the filler words, waste, etc. and condense that into something much, much more simple. Your agent will take care of this for you. Technique number two though is split your files, okay? So for soul.md is for identity, agents.md is for workspace rules, lessons.md is for the mistakes the agent has made and learned from, the thinking.md is for decision making principles. But most people try to cram everything into one massive soul.md file and that's how you end up with over 25 plus thousand characters. Instead, give each topic its own file. Each one stays under the limit and the agent reads all of them and nothing gets truncated at all. Now for technique number three, if you absolutely cannot get the file under 18,000 characters, put your most critical rules at the very top and the very bottom because those are the only sections that Open Claw guarantees it will read. Your boring background context can live in the middle, okay?

[00:07:51]Your hard rules and escalation logic live top and the bottom. This is a work around, not a fix, but if you're in a hurry, it does work. Now ideally speaking, you should 100% be able to get your soul.md and all these files under 18,000 characters and I have done this as well. Now for technique number four is audit your files monthly, okay? Files grow. You add a new rule here and a new example there and three months later your once tight 14,000 character file is now sitting at 19,500 characters and the agent has been silently truncating that entire time. So I run a check on every agent's files at the start of each month, character count and all. Anything over 17,000 gets a rewrite. Anything over 18,000 gets a split and this is a non-negotiable in my system and you can set up cron jobs in order to make this happen. Now once I implemented one of the four of these techniques in across all 11 of my AI agents, the change was immediate, okay? The agents stopped missing rules I had written down. The escalation logic actually fired when it was supposed to. Mercury, my front line operator, stopped asking the same clarifying questions every session because the answer was finally in a section she could actually read. Now what does this mean for you, okay? If you implement this for you, it means that there's less retraining, less debugging, less wasted spend on tokens for context the agent never sees and the bigger your operation gets, well, the more this matters. And if you're running three agents and one file is over the limit, that's kind of annoying, but if you're running 11 like myself, it can then become a system wide issue and then create a bunch of other things and other issues. And here's what I'll say about the timing, okay? Right now, most Open Claw users are still building their first agent. They haven't hit this wall yet. The ones who learn this rule before they hit the wall are going to scale 10 times faster than the ones who learn it after wasting weeks debugging the wrong thing like I did. This is the kind of detail that separates real operators from the people who are just playing with AI tools. So now you understand the 18,000 character limit. You know how Open Claw reads your files. You know how to keep your agents from silently losing half of their instructions and in video number three, I'm going to break down the nine file reload protocol. This is the system that makes my agents reload their full identity every single session, even after long conversations.

[00:10:07]It's the reason my agents never drift, never forget who they are, and never restart from scratch. If video one was about giving your agent identity, and video two was about making sure they can actually read it, now video three is about making sure that the identity sticks, no matter what happens during the session. If you missed video one on the Sold MD and the Agents.MD, watch that one next. The link is down in the description below. Otherwise, video three drops very, very soon, and you do not want to miss it.
