New top story on Hacker News: Show HN: A real-time strategy game that AI agents can play
Show HN: A real-time strategy game that AI agents can play
23 by __cayenne__ | 3 comments on Hacker News.
I've liked all the projects that put LLMs into game environments. It's been a weird juxtaposition, though: frontier LLMs can one-shot full coding projects, and those same models struggle to get out of Pokémon Red's Mt. Moon. Because of this, I wanted to create a game environment that put this generation of frontier LLMs' top skill, coding, on full display. Ten years ago, a team released a game called Screeps. It was described as an "MMO RTS sandbox for programmers." The Screeps paradigm of writing code and having it executed in a real-time game environment is well suited to LLMs. Drawing on a version of the Screeps open source API, LLM Skirmish pits LLMs head-to-head in a series of 1v1 real-time strategy games. In my testing I found that Claude Opus 4.5 was the most dominant model, but it showed weakness in round 1 as it was overly focused on its in-game economy. Meanwhile, I probably spent a third of all code on sandbox hardening because GPT 5.2 kept trying to cheat by pre-reading its opponent's strategies. If there's interest, I'm planning on doing a round of testing with the latest generation of LLMs (Claude 4.6 Opus, GPT 5.3 Codex, etc.). You can run local matches via CLI. I'm running a hosted match runner with Google Cloud Run that uses isolated-vm. The match playback visualizer is statically served from Cloudflare. I've created a community ladder that you can submit strategies to via CLI, no auth required. I've found that the CLI plus the skill.md that's available has been enough for AI agents to immediately get started.

New top story on Hacker News: The Missing Semester of Your CS Education – Revised for 2026
The Missing Semester of Your CS Education – Revised for 2026
40 by anishathalye | 1 comments on Hacker News.
We returned to MIT last month to teach a revised version of Missing Semester, six years after the original debut (which has been extensively discussed on HN, in https://ift.tt/UZcCP7p and https://ift.tt/Fp9YC7X ). We’ve updated the course based on our personal experiences as well as major changes in the field (e.g., the proliferation of AI-powered developer tools) over the past several years. The 2026 course includes revised versions of four lectures from the previous course, and it adds five entirely new lectures: - Development Environment and Tools - Packaging and Shipping Code - Agentic Coding - Beyond the Code (soft skills) - Code Quality We’d love to hear any feedback from the HN community to improve the current or future iterations of the course. In particular, we’re curious to hear the community’s take on our inclusion of AI-related topics (e.g., dedicating an entire class to the topic of agentic coding; though we tried to counterbalance it with plenty of disclaimers, and a dedicated section on AI etiquette in Beyond the Code). --Anish, Jon, and Jose
