@hwchase17 @LangChain I built an open-source CLI that scaffolds, runs, and deploys production LangChain agents — frontend and backend in one command. Every agent project starts the same way: wire up a LangGraph backend, scaffold a Next.js frontend, figure out CORS, hide API keys, set up a proxy. Two days gone before you write a single line of agent logic. langctl kills that. langctl new my-agent cd my-agent langctl dev That's it. Agent + chat UI running at localhost:3000. One URL. No CORS. No exposed keys. How it actually works: langctl new scaffolds a LangGraph Agent Server backend and a Next.js frontend, wired together through a built-in proxy. The browser only ever talks to /api/agent/* on the frontend's origin — the proxy attaches x-api-key server-side. Zero cross-origin requests, ever. langctl dev starts both processes, waits for the agent's health endpoint before booting the UI, and tears everything down cleanly on Ctrl-C. Like next dev, but the backend is an agent. Three chat UI options out of the box: assistant-ui (default) — threads, branching, composer runtime minimal — one hand-written Chat.tsx, zero UI deps ai-elements — shadcn-registry components (experimental) Other commands: langctl sync — regenerates langgraph.json from agent.yaml, preserves hand-written keys langctl doctor — verifies toolchain, ports, keys, and config before something breaks agent.yaml is your single source of truth. Dev and production differ by one env variable. The frontend source doesn't change. Phase 1 (scaffold + unified dev runtime) is live on PyPI. Deploy providers (LangSmith Cloud, Vercel) are next. Apache-2.0 licensed. Generated projects carry no license obligation to this tool. GitHub: PyPI: pip install langctl and build your next agent in minutes, not days.

It’s so interesting how Adult Swim is fine with like a huge amount of rape jokes, but this deeply serious portrayal of what the victims of misogynistic sexual violence go through was “too depressing”

i was literally in the shower, soap in my eyes, when a massive fat-ass lizard dropped from the ceiling, landed dead on my bare arm, and scratched me. i screamed so hard i slipped on the tile and ripped the entire shower curtain off the wall trying to slap it off. and the worst part is my husband literally warned me this exact thing was gonna happen...

I once heard someone say, “Couples shouldn’t have separate hobbies. If you love each other, you should want to do everything together.” Meanwhile, my husband and I have happily accepted that I can spend three hours doing absolutely nothing while he gets excited about the most random thing imaginable. You don’t need to share every hobby, every interest, or every little obsession to have a strong relationship. Sometimes loving someone means giving them space to enjoy the things that make them happy—even when you don’t understand the appeal.
