Beyond Vibe Coding: Engineering Resilient AI Agents with FSMs, Privacy, and Cost Controls

Originally published on tamiz.pro. The era of "vibe coding"—where developers rely on large language models (LLMs) to generate entire applications through natural language prompts without deep structural oversight—is hitting a hard ceiling. While LLMs are exceptional at generating boilerplate, writing unit tests, or refactoring legacy code, they are fundamentally probabilistic engines. They lack d...

Build a PDF Text Extractor with Python

Build a PDF Text Extractor with Python tags: python, pdf, tools, tutorial You’ve probably stared at a PDF full of data you need—maybe a research paper, a financial report, or a contract—and wished you could just copy-paste the text. But PDFs are designed to look good, not to be easily parsed. That’s where Python steps in. With just a few lines of code, you can build a reliable PDF t...

Knowledge and Memory Management: Directions 1-3 Finalized

We’ve just closed the documentation cycle for Directions 1 through 3 in the Knowledge and Memory Management project. This marks a concrete baseline for systems that need to persist, recall, and apply learned information over long interactions. No fluff, no theoretical sandboxes — these directions define the core substrate that agents and applications use to decouple knowledge from transient execut...

Claude Mythos Just Found Real Cracks in Two Cipher Designs

Anthropic said Claude Mythos Preview helped derive a real key-recovery attack against the HAWK-256 post-quantum signature scheme, cutting its estimated attack cost from roughly 2 to the 64th power operations down to 2 to the 38th Mythos separately found a technique it called a Mobius Bridge that speeds up a known attack on 7-round AES-128 by 200 to 800 times HAWK had already survived two full yea...

Established is not a status label — it's a write permission

Originally published at https://blog.pathvector.dev/protocol-in-code-bgp-11/ — part of the free Protocol Lab series. This post is part of Protocol in Code, a free series that reads network protocols not as configuration examples but as logic — inputs, state, and branches. Every session points at a small Python file and asks you to read it the way you'd read any other program. The source lives a...

Four Models Cited My Numbers Perfectly. One Still Misread Them.

Originally published on hexisteme notes. I recently froze a table of behavioral metrics computed from 281 of my own AI-agent sessions and ran it through two separate checks before I let myself trust any conclusion drawn from it. Both checks passed. Neither one verified the thing I actually needed to know — and both failures turned out to have the exact same shape. The underlying table is observa...

Human Software [book]

A book about work, felt like work. I suspect this is very specific to me, but I found the majority of the story pretty triggering - specifically, I felt pissed off a lot of the time I was reading. After reading the About the Author section at the end of the book, it looks like I've had a similar timeline of a technical career to them (which perhaps is why the story got under my skin). This is beca...

Why Your RAG Pipeline is Lying to You

RAG (retrieval-augmented generation) is how most AI tools search your company's documents to answer questions. Instead of guessing, the model pulls relevant text from your files and uses it to respond Sounds reliable. Usually isn't. Last month, our team shipped a RAG-powered search feature to a Fortune 500 client. Three days later, this Slack message showed up : "The AI pulled a revenue number...

LLM TRADER BOT

Let me tell you a story about failure. Late 2024. I'm sitting in my Wrocław apartment after an 8-hour warehouse shift. My back hurts. I've been trying to make a trading bot work for two weeks. Every night, same result: the LLM generates beautiful-sounding analysis. Confident. Articulate. Completely wrong. "RSI is 28, oversold. BUY." Next morning: -4.2%. The problem wasn't the LLM being stupi...

Your AI Subagents Are Lying to You: 4 Silent Failure Modes

I fanned a design-token sweep out to parallel Claude Code subagents: roughly 317 hardcoded hex colors scattered across an app's screens and components, all to be replaced with tokens from a central theme file. Each agent got a slice of files and reported back when done. The reports came in clean. The grep afterward disagreed. Some slices were untouched, and the agents responsible had said nothing,...
