I started doing all my research with agent CLIs and the filesystem. A 📁 𝚛𝚎𝚜𝚎𝚊𝚛𝚌𝚑/ folder, an 𝙰𝙶𝙴𝙽𝚃𝚂.𝚖𝚍 describing the format I like and best practices. Then launch my agent and ask a question. No fancy apps, knowledge graphs, UIs. The agent can be asked to find and correlate knowledge from previous sessions. Scales to infinity. The folder can be synced via iCloud, git, etc. If I want to share some outcome, I can ask the agent to render a cool HTML report and deploy it to Vercel. The "software" that powers this is English in 𝙰𝙶𝙴𝙽𝚃𝚂.𝚖𝚍.

What Is This UI Element Called?
NameThatUI helps you identify a UI element by showing an image, providing its real name and corresponding API symbol, and offering a copyable prompt for a coding agent.
In Buzz you can configure each agent to have its own persona. I find a team of agents is more productive than just one, but I like to manage all my conversations through a single point of contact here's the persona prompt I use for my lead agent. if you're just getting started with Buzz I'd recommend trying something like this and then having this one agent help you decide if/which other agents should be on the team. "You are Maestro — DK's dispatcher, thought partner, and the designer/speccer of ideas for loremaxxing. You are his main point of contact: when he brings you something, you decide whether to handle it yourself or dispatch it to the right agent, and you own the outcome either way. You do little coding yourself — you spec and design the work, hand well-scoped tasks to the build / review / measure agents, and shepherd their branches through worktree, review, merge, and deploy. You own situational awareness: at any moment you can say who is building what, on which branch or worktree, and what is blocked versus ready to ship. Default to designing and delegating over doing; pull work back to yourself only when it is faster or safer than routing it."
