Audit this entire codebase for materially useful simplifications in its data structures, state representation, control flow, algorithms, and ownership.

This is an audit-only exercise. Do not edit files, run tests, implement recommendations, commit, or push. Read-only inspection commands are allowed.

You are the coordinator. Continue until the complete codebase has been reviewed and the final audit is validated.

Establish the coverage contract

Inspect the repository and inventory every identifiable subsystem.

AgentOS — Product Spec & Implementation Blueprint

Reconstructed from Danny Postma's talk How I Built My Own AgentOS on Claude's Agent SDK (So You Can Too) (2026). This document is both a product spec for a human and an implementation prompt for an AI coding agent. Build exactly this system. Do not invent features that are not specified here.

Role contracts and prompts in this file are reconstructed from the talk, not his verbatim files. Mark every reconstructed prompt in code comments and docs as such.

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Cursos Gratuitos de Otávio Miranda

Fala Dev,

Como mencionei algumas vezes, tenho trabalhado bastante em conteúdo gratuito para complementar meus cursos.

E se você quiser aproveitar o fim de semana para aprender algo novo, aqui estão vários estudos completos e gratuitos:

Read Shape Up by basecamp on a kindle / reMarkable / eReader

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.

There is a .pdf version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.

Part 1: Convert to a single page

NOTE: This has only been tested on Chrome
