This week inside Agentic Labs, the challenge was to build your own coding agent CLI from scratch, and members ran with it in every direction. One shipped a working agent to PyPI that runs on free models for $0. One used their tiny agent to spit out a full Tetris game. And one went his own way entirely and built production desktop tools to tame a real logistics headache at work. Some were polished and public, some were first wobbly steps into brand new territory. Both matter. 🚀 Standout wins from Agentic Labs: 👉 @Srinivasan Kanniwadi built and shipped letscode, a coding agent that runs the full read, write, and edit loop in a single file, powered by any LLM through OpenRouter (including free models, so the whole thing can run for $0). He published it to PyPI so anyone can install it: https://pypi.org/project/letscode-cli/ 👉 @Emile du Toit built SKINNYCODER, a lean amber-terminal coding agent in TypeScript powered by Codex, built around explicit edits: it shows you a diff and waits for your approval before it writes a file or runs a command. He went out of his way to keep the startup footprint tiny and documented exactly why in the repo: https://github.com/brainit-consulting/skinnycoder 👉 @Michael Bustos took the week in his own direction and built what he actually needed for work: a PDF editor (a mini Acrobat clone that creates and edits form fields) and an image-to-PDF merge tool, both Windows desktop apps built with Electron, Next.js, and PDF.js, to streamline a sponsorship project spanning six countries. Built so non-technical teammates can use them too. 👉 @Radu Crisan built a tiny coding agent straight from the challenge, kept it dead simple, and then had it generate a full working Tetris game. Proof a small harness can punch way above its weight. It's up on GitHub: https://github.com/radukc/zoomylight
