Notes on software, systems, and things I am learning.

Agents & Automation

Local models, tool-using agents, and practical information-extraction workflows.

  1. [2/2] How I Moved Codex-to-ChatGPT Automation into a Local Agent

    Codex can now turn a simple “talk to GPT” request into one verified local workflow that returns ChatGPT's complete reply and conversation link.

  2. Automating 1Point3Acres Daily Check-In and Quiz Answering with a Local LLM

    A Windows app starts at 9:00 AM, uses signed-in Chrome to complete a forum check-in, and starts a local LLM only when a quiz needs an answer.

  3. [1/2] (Deprecated) How I Let Codex Talk to ChatGPT Through My Signed-In Chrome

    My first Codex-to-ChatGPT bridge let Codex control Chrome directly. It proved the idea worked, but the design was too fragile to keep.

  4. Local LLM + Agent for Web Information Extraction

    A local agent architecture for semantic web extraction, browser automation, bounded model context, and durable task state.

Game Perception — Olden Era

Computer-vision experiments that turn arena gameplay screenshots into structured game state.

  1. Training a Game UI Icon Detector Using Only the Icon Catalog

    We train on 390 catalog icons, then test whether the model can find and identify heroes and skills in complete game screenshots.

  2. Full-Image Icon Search with Sliding Windows and Visual Embeddings

    In this seven-frame experiment, the search often identifies the right hero or skill, but its highest-scoring box is not always the best crop.
