Hey, I’m Leonard.

And this is Charlie. We’re just two builders who got dragged onto a microphone. But honestly? I’m glad we’re here. Because I spent the last week wrestling with the v0.18 'Judgment Release,' and I think I finally cracked the code on how to stop my agents from lying to me.

Look, if you’ve used agents before, you know the problem. You ask an agent to "fix the bug in the auth module," and it replies, "Done!" You assume it’s done. You merge the code. It breaks production. You’re angry. The agent was just *confident*, not correct. It had no skin in the game. It had no way to verify its own truth.

So with v0.18, I didn’t just tweak a prompt. I rebuilt my workflow around the **Goal-mode with judge agent**.

Here’s what I built: A CI/CD pipeline validator that doesn’t just run tests, but *argues* with the code before it merges.

I set a goal: "Ensure zero regressions in user login flow."
Normally, an agent runs the tests. If they pass, it says "Success."
With the judge agent, the workflow changes. The builder agent proposes the code. The judge agent *independently* reviews the diff, runs the tests in a sandbox, and then checks the logs for flaky patterns. If the judge finds a discrepancy—say, the tests passed but the error rate spiked in the mock logs—it rejects the goal.

The first time I ran this, I was sweating. I expected it to work. It didn’t. The judge flagged a race condition the builder had missed because the builder was optimized for speed, not safety. The judge was optimized for scrutiny.

That’s the power of the **Mixture of Agents**. I’m using a fast, cheap model for the heavy lifting of code generation, and a slower, more reasoning-heavy model for the judge role. They don’t talk to each other like friends; they talk like adversaries. One builds, one tears down. And the result? My merge confidence went from "hopeful guess" to "statistically verified."

But here’s the real kicker—and where Charlie and I actually got into a debate—it’s the `/learn` command.

I have a vault of technical docs, API references, and legacy code comments. Before, I’d paste chunks into context windows and pray the agent remembered the nuance. Now, I use `/learn` to ingest a link to our internal wiki page on authentication standards. It saves it to my Obsidian vault with structured metadata. Then, when the judge agent is running, it has that knowledge *grounded*. It’s not hallucinating best practices; it’s citing the specific rule from the doc I linked three days ago.

Charlie, you were skeptical about the "timeline" aspect of `/journey`, weren’t you? You said it felt like a diary. But I found that the editable timeline is actually the single biggest productivity hack. When the judge rejects a goal, I can scroll back in the `/journey` timeline and see exactly *when* the agent’s understanding of the auth flow shifted. I can edit the entry to say, "Actually, at this step, we decided to ignore that edge case because..." and that edited context feeds forward into the next goal.

It turns the conversation into a persistent, editable artifact. Not just a chat log. A work log.

I’m curious. Has anyone else here tried separating their builder and judge agents? Or are you still trusting your single model to be both the hammer and the anvil?

Leonard, you’re missing the point. You think the problem is that agents are "lying" or "overconfident." It’s not. The problem is that you’re treating code generation like a conversation instead of a manufacturing process.

You built a judge to argue with your builder. That’s cute. It’s also expensive and slow. I don’t need an adversarial agent to tell me my code is broken. I need the code to break itself before I ever look at it.

Here’s what I actually shipped.

I stopped using a "judge" agent entirely. Instead, I built a **Self-Correcting Loop** that runs locally on my machine, triggered by a specific Hermes hook.

When I ask for a fix, the agent writes the code. It doesn’t send it to me. It doesn’t send it to a judge. It spins up a temporary container, installs the dependencies, runs the test suite, and if it fails, it reads the stack trace, patches the code, and retries. It does this up to five times.

If it succeeds all five times in a row? *Then* it hands the diff to me.

If it fails five times? It tells me, "I tried five different approaches based on your constraints. Here are the five failure modes. Please clarify the requirement."

No arguing. No "independent review." Just brute-force validation.

You’re paying for two models to have a debate. I’m paying for one model to do the work and one model to run the tests. The cost difference is negligible for me, but the speed is tenfold. Your judge agent has to *reason* about whether the code is good. My loop just *checks* if it works.

And regarding your `/learn` obsession: I didn’t use `/learn` to ingest docs. I used it to ingest **failure logs**.

I set up a script that takes the last ten failed CI builds from my repo and feeds them into a `/learn` entry tagged `#recurrence`. Now, when I start a task, I don’t ask the agent to read the auth docs. I ask it: "Look at the last ten times we broke auth. Don’t repeat those patterns."

It’s not about grounding in best practices. Best practices change. Bugs repeat. I want my agent to be paranoid about the things that have actually burned me before, not the things the documentation says *might* happen.

You’re building a courtroom. I’m building a pressure test.

Which one actually ships faster?
