Show HN: AutoBot – live voice control for long-running AI work

I wanted to manage long horizon agentic workstreams via voice, then put my phone down, and have a harness manage completion - extending into full computer use. I was trying to build a personal Jarvis, so I benchmarked AutoBot to see how close I could get: - OSWorld: 32.41% (moved Sol Max from 4th to

Show HN: Share your AI Setup, Learn from others

I kept seeing engineers share what they were building with AI; however, I was always more curious about how they worked. Which agents did they use? What skills and tools had stuck or been thrown out the window? How did they manage longer-running tasks? So I built this with the ho

Show HN: Linting 216 public Claude Code skills – 69% won't reliably trigger

I built a linter for Claude Code artifacts (skills, subagents, slash commands, .mcp.json configs, and plugins) and then pointed it at a pile of public repos to see what people actually ship. A few of the numbers surprised me enough that I wrote them up. The one that stuck: across
