Thanks2Go: Building a Human-Approved Gratitude Rail in One Weekend
I used Codex to its fullest potential as a research partner—for code mapping, source comparison, evidence organization, consistency checks, editorial control, and deliverable preparation. I formulated the intent, defined the scope, interpreted the results, arbitrated the conclusions, and preserved every public decision. This collaboration expands my investigative capacity; judgment, responsibility, authorship, and final signature remain under my authority. This is a submission for Weekend Challe
Building a Secure Personal Gemini Journal with Google Cloud
Most AI apps look impressive in a demo, but building one that is secure, authenticated, and production-ready is a completely different challenge. For my project, I built a Personal Gemini Journal — a private AI-powered journaling application where users can sign in, write their thoughts, chat with Gemini, and get personalized insights from their journal history. 🔐 Security First Instead of starting directly with code, I first configured Google AI Studio with security-focused custom instructions

WebMCP lets a page give the browser's agent a real function instead of a DOM to guess at. You call document.modelContext.registerTool({ name, description, inputSchema, execute }), and the agent can list the tool and call it. The feature sits behind a Permissions Policy whose default is self. On a normal site that default does the isolation for
AI Accountability Coach Agents in 2026: Automate the Between-Session Follow-Up, Then Rent It Out
TL;DR: Accountability is the least glamorous, most valuable part of coaching — and it doesn't scale by hand past a small roster. An AI accountability coach agent closes the gap between sessions: it remembers each client's commitments, checks in on a deliberate cadence in the coach's voice, adapts to the reply, flags at-risk clients, and hands the coach a pre-session digest. This post walks through the architecture of that between-session follow-up loop and makes the 2026 market case for why owni
