Show HN: Product analytics (and evals) for agent sessions on your MCP Hi HN! We’re Theodore and Louis, founders of Armature (YC P26). We reconstruct the entire session behind the MCP tool calls you receive, including what the user asked their agent to do and what the agent thought. You wrap your MCP in 3 lines of code (our SDK is available in Typescript, Python and Go) and start seeing in your dashboard: - All sessions reconstructed: it’s like reading the real conversation the user had inside Claude or ChatGPT! - A ranking of your MCP most popular use cases, built from sessions clustering - The most frequent issues your users’ agents encounter so you can fix them. Here is a quick demo: https://youtu.be/ZFlvquhyNMQ The story behind this is that we initially launched Armature as a standalone testing tool ( https://ift.tt/Gewlbqj... ) that could naturally be used through an MCP itself. We quickly realized we had no idea how our users were using Armature MCP and if they were satisfied wi...

Show HN: Schmess – chess with no turns; pieces freeze on cooldown after moving Solo dev here. Schmess is chess with the turn structure removed. Both players move whenever they have a free slot, and every piece freezes on a cooldown after it moves. It's on a half board, with 100+ puzzle stages. If two people played this over a physical board they'd scrape each other's fingers raw - that's roughly the tempo. Plays in the browser, no signup. 29 stages free, one-time unlock for the rest ($3.99 / Rs 149). No subscription, no ads. It's the second of a few small-board variants I'm building (halfchess was the first, more coming). Building a chess engine for a game with no turns turned out to be the hard part - I've put the war stories in a comment below. https://schmess.com/ August 2, 2026 at 11:47PM

Show HN: Sprocket – The Best AI Agent for Hardware and Software Development Hey HN, I am 16y/o and have been working on Sprocket for a while. It's an open-source AI agent that beats every other agent out there at both hardware and software. And here's the best part: Sprocket can (on its own) buy anything from any website when you tell it to do so. From hardware parts to SaaS subscriptions. Sprocket retrieves best-in-class context from the web for everything it does. It is therefore incredibly reliable. The agent harness's quality, performance, and UI rival that of Codex/Cursor/T3Code, and we are rapidly improving. We will be releasing benchmarks on how Sprocket beats every other agent at both software and hardware soon. In terms of hardware design, Sprocket can make beautiful schematics in react, create your BOM, and create detailed assembly instructions. Hope you try it out! Thanks, Aarav P.S. if the demo video doesn't load for you, come back after ~1.5hr and it should...
