Sanju's Ideals — Claude Code Skill

A Claude Code skill that applies Sanju Sivalingam's design, engineering, and product ideals as a thinking lens — distilled from his writings and thoughts at sanju.sh/writings and sanju.sh/thoughts.

Invoke it on any piece of work to get feedback or a review through his lens: subtract before you add, show don't describe, capture the why, right-size the tool, and more.

AGI SDK Binary Architecture - Claude Code Pattern

AGI SDK Binary Architecture

This document describes the AGI driver binary and SDK architecture. The driver is a self-contained agent that captures screenshots, reasons with Claude, and executes actions autonomously. SDKs are thin event wrappers.

Using Claude Code Programmatically: A Complete Guide

TL;DR: Claude Code has a built-in --print --output-format=json mode that bypasses the TUI completely, giving you clean programmatic access to Claude as an async agent runtime.

The Discovery

While building a document editing agent system, I discovered that Claude Code's binary includes a first-class JSON output mode that completely bypasses the terminal UI rendering, making it perfect for programmatic use.

How to Build Software When You're Too Lazy to Build Software

Or: I Accidentally Invented a Way to Make Computers Program Themselves Because I Got Tired of Explaining Things Three Times

Look, I'm going to be honest with you. I built an entire campaign management system—email automation, AI filters, scheduled triggers, the whole nine yards—basically by myself. How? Well, I fired three contractors trying to build it before I realized I could do it myself. By "myself" I mean I got GPT to do it while I ate chips and occasionally typed "looks good, continue."

I haven't actually read the rest of this post yet but I'm pretty sure it's genius. Here you go.
