https://github.com/carlos-menezes/target-run

Platform-aware script runner for Node.js projects.

  pnpm add -D target-run
Set a script body to `target-run`, then define platform/arch variants:

  {
    "scripts": {
      "test": "target-run",
      "test:darwin:arm64": "jest --config jest.apple-silicon.config.ts",
      "test:linux:x64": "jest --config jest.linux.config.ts",
      "test:default": "jest"
    }
  }

Building VizPy, a prompt optimizer we've been working on for a while now.

The problem it's solving is one most people building with LLMs know well. Your prompt fails on some inputs, you don't really know why, and you end up just tweaking and re-running until something sticks. We kept hitting this ourselves and it felt like there had to be a better way than guessing.

What we figured out after a lot of research: prompt failures almost always follow a pattern. The model isn't failing randomly, it's consistently failing on a particular type of input or reasoning step. VizPy finds that pattern, distills it into a plain English rule you can actually read, and then rewrites your prompt around it. You also get the rule itself so you can review it, tweak it, or just drop it into your existing prompt directly. DSPy-compatible, no pipeline rewrite needed.

We have compared it extensively against baselines such as GEPA on benchmarks like BBH, HotPotQA, GPQA Diamond, and GDPR-Bench and VizPy wins on all of them. We'll have more benchmarks on cyber-security and chip-design coming out soon.

Getting a D&D group together in person has been getting harder and harder, and we've had less and less time to DM. I decided to build an agentic AI to handle the work of setting up and running a campaign so we could all participate. It supports real time (preferred, and probably more fun) or async. The agent performs most functions through tool use so it's all 5e rules based but I wanted to leave it a good amount of freedom so campaigns can go on tangents and have fun surprises.

I'm still playtesting it with friends and it's been fun. It's in early access, I don't feel right charging for it unless other folks actually end up liking it and thinking it's fun. If you sign up, send me a message through "Send Feedback" (or here!) and let me know if you like, but especially let me know if you hate it.

I just claude coded a a decision journal that uses the Choose Your Own Adventure style of mapping out different pathways and outcomes. I've been dealing with a lot of major life decisions lately and I had some inspiration to use the CYOA format to help me work through different scenarios. It's actually really fun, and super useful to get AI to generate some potential outcomes too.

You can either use your own Anthropic/OpenAI key to play, or buy credits. I also have a free non-commercial version on my github you can fork.
