How I Built an AI Harness That Ships Products on Its Own
Updated: at 08:34 PMEveryone is waiting for a smarter model. I spent that time building the operational wrapper around the model we already have, a multi-agent harness that takes a one-line task and returns a deployed product for about five cents. Here is how it actually works, and what shipping hundreds of autonomous tasks taught me.
A Paywall for AI Agents, Built on a Forgotten HTTP Code
Updated: at 09:37 AMHTTP 402 "Payment Required" was reserved in 1997 and never shipped. I used it to build a paywall that AI agents can pay through on their own, with on-chain settlement, non-extractable keys, and verification that runs on an edge function with no database. Here is how the handshake works and the decisions that made it safe.
Proof of Mandate, or How to Hijack an Agent and Steal Nothing
Updated: at 04:52 PMThe industry's reflex on agent safety is "make the model safer." I think that is the wrong fight. Assume the model will be fully compromised, and make the theft impossible anyway, by turning the agent's permissions into a keyring it cannot exceed rather than a rulebook it is asked to follow. Here is the design, and a demo where a jailbroken agent tries to drain a treasury and fails at signing time.
The Inference Substrate, or Why Every AI App Pays a Tax It Cannot See
Updated: at 11:26 AMEvery company building on closed AI models pays a permanent, growing tax in cost, latency, and wasted generality. There is no infrastructure layer fixing it, and the model companies structurally cannot build one. This is the thesis for the layer that should exist in the empty middle, and why it is an infrastructure and cryptography problem rather than an AI research one.
A Coding Agent That Proves Its Fixes and Never Leaves Your Network
Updated: at 02:08 PMA bank cannot send its source code to a US AI API. So I built a coding agent that runs fully air-gapped on the customer's own hardware, is model-agnostic, and never claims a fix works until it has run the repo's own tests and watched them pass. The interesting result was that the harness, not the model, was where the capability lived.
Optimizing MySQL Indexing for Maximum Performance
Published: at 04:00 PMIndexing in MySQL is a performance optimization technique that involves creating data structures on specific columns to accelerate query retrieval, but misuse, such as over-indexing or choosing inappropriate columns, can lead to database inefficiencies and performance issues.

Separating Signal from Noise on YouTube with One Claude Call
Updated: at 06:48 PMA 20-minute YouTube video is often 30% substance and 70% sponsor reads, plugs, and hype. I built a tool that reads the transcript, hands it to Claude once, and returns only the claims, data, and arguments worth your time. Here is the architecture, the plumbing that fights YouTube's bot blocks, and why the whole product is really just one prompt.
