Project mention: I Don’t Make Slides Anymore. My Agent and Entire Do It for Me. | dev.to | 2026-04-25
I've looked for a way to automate slide generation, but most options have been fragile. They generally struggle with formatting and taste. However, a few months ago, some of my teammates at Block discovered the frontend slides skill and introduced me to it. This skill enables agents to build out HTML presentation decks that can be exported as PDFs or PowerPoint presentations.

obsidian-second-brain
Persistent memory for Claude Code and 6 other CLI agents, stored as plain markdown in your Obsidian vault. Stop re-explaining your projects, decisions and people every session. 45 commands: hybrid semantic search, self-rewriting notes, key-less web research, and scheduled agents that maintain the vault while you sleep.
Project mention: A Vault That Rewrites Itself: obsidian-second-brain and the Karpathy LLM Wiki Pattern | dev.to | 2026-10-08Two tools most of us own ignore each other completely. An Obsidian vault with hundreds of notes nobody rereads. An AI agent in the terminal whose every session starts from zero, as if the past never happened. The obsidian-second-brain repository glues them together: 4.7k stars, MIT, authored by Eugeniu Ghelbur. The README's own formula: an evolution of Karpathy's LLM Wiki pattern, a vault that rewrites itself. Here's a review, plus why I read the whole thing with deja vu: my business CRM runs on the same pattern.
