Show HN: Skillscript – A declarative, sandboxed language for tool orchestration Hi HN — I&#x27;m Scott. Skillscript is a small language I built to write what I want my local agent to actually do, in a form I can read and version, instead of hoping the model gets it right each time.<p>The itch started with something small. I wanted my NanoClaw agent to run my morning brief the same way every day. Check overnight tickets, summarize the deploy pipeline, flag anything urgent. Every session, it would re-figure out how to do this from scratch, drift a little, and cost tokens for what&#x27;s basically a fixed procedure. I could put it in a system prompt or an MD skill file, but those are still instructions the model reads and reasons about every time. And I wanted it to run autonomously and then hand it to the model to reason over the data.<p>The second thing that pushed me: I wanted to use small local models for the cheap stuff. They&#x27;re capable, but if you just hand them the wheel, they wander. What I wanted was a way for the frontier model (or me) to write a specific procedure and hand it to the local model to execute, not interpret. The skillscript is the program; the model is the runtime.<p>Skillscript is that. A skillscript is a text file with named steps, variables, conditions, and calls out to tools (MCP connectors, a local model, and shell commands from an operator allowlist). It&#x27;s deliberately minimal — no eval, no arbitrary imports, no subprocess, no unbounded loops. Bounded language, limited potential for damage. Everything a skillscript can do is in the file. You read it and know.<p>Where it is: pre-1.0 (0.30), MCP-native, self-hosted. Rough edges I know about: first-run setup takes more steps than it should, some of the grammar is still moving, and the local model integration currently assumes Ollama. It works well enough that I use it every day, but I wouldn&#x27;t necessarily call it production-ready.<p>- Repo: [<a href="https:&#x2F;&#x2F;github.com&#x2F;sshwarts&#x2F;skillscript" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sshwarts&#x2F;skillscript</a>](<a href="https:&#x2F;&#x2F;github.com&#x2F;sshwarts&#x2F;skillscript" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sshwarts&#x2F;skillscript</a>)<p>- Site: [<a href="https:&#x2F;&#x2F;skillscript.ai" rel="nofollow">https:&#x2F;&#x2F;skillscript.ai</a>](<a href="https:&#x2F;&#x2F;skillscript.ai" rel="nofollow">https:&#x2F;&#x2F;skillscript.ai</a>)<p>- Docs: [<a href="https:&#x2F;&#x2F;skillscript.mintlify.app&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;skillscript.mintlify.app&#x2F;docs</a>](<a href="https:&#x2F;&#x2F;skillscript.mintlify.app&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;skillscript.mintlify.app&#x2F;docs</a>)<p>- npm: `skillscript-runtime`<p>I&#x27;d welcome critique on two things especially: the language design (is it too small? too big? wrong shape?) and the trust model around agent-authored skills. What would you want to see before you trusted this on your own machine?

Show HN: The Quiet Map – Earth's quietest place, measured by seismometers Hey HN,<p>This started as a personal curiosity and Claude helped me build it out.<p>The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now.<p>Hope you enjoy it and would love your feedback!

Show HN: OpenBenchmarks – Helping agents discover and pick the right SaaS APIs I&#x27;m Fenil, co-founder&#x2F;CEO of OpenFunnel (YC F24), building this with my co-founder&#x2F;CTO Aditya. We&#x27;re launching OpenBenchmarks (<a href="https:&#x2F;&#x2F;openbenchmarks.com" rel="nofollow">https:&#x2F;&#x2F;openbenchmarks.com</a>), open-source, reproducible benchmarks for SaaS APIs, starting with the category we know best: GTM APIs.<p>## Why we built this<p>More and more B2B software evaluation will&#x2F;already runs through reasoning models inside agentic workflows rather than through people. And buyers increasingly pick vendors that are API-first and ship MCPs, so they can wire them into internal workflows. Strong reasoning models are skeptical of marketing. When a genuinely neutral benchmark is available, they discount SEO and self-published benchmarks, and they lose trust the moment something looks like a marketing claim.<p>The thing that survives that skepticism is an independent build-first benchmark the agent can reproduce itself and trust.<p>Reproducible by default: every cell ships the literal HTTP request&#x2F;response plus the judge prompt&#x2F;response<p>All benchmarks live at <a href="https:&#x2F;&#x2F;github.com&#x2F;openbenchmarks-labs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;openbenchmarks-labs</a>. We start with GTM APIs, with more on the way.<p>## On Benching ourselves<p>We benched our own product (OpenFunnel) as a vendor in the lookalikes benchmark, on purpose.<p>We increasingly saw buyers asking for benchmarks on sales calls and were also curious to see if agents also made decisions the same way.<p>We wanted to see whether an agent could run the whole loop end to end: discover the benchmark while researching a user&#x27;s query, weigh it as the deciding factor in picking a winner for that user&#x27;s category, then sign up and auth through to the chosen vendor to complete the task. That last stretch needs live vendors with agent-auth wired up: us and a few others.<p>We came out #1 on the current seed (89% vs 74%). Because it&#x27;s open, we don&#x27;t win everything: depending on seed and metric (precision@10&#x2F;@50&#x2F;@100), we win some and lose others.<p>## Dogfooding<p>We dogfooded it and ran 200 incognito simulated buyer flows through Claude Code with live web search, from query to discovery to sign-up, and watched which sources the model fetched and which ones made it into the final decision. The benchmark got opened in a large majority of runs, across the range of queries an actual buyer would ask in Claude Code, from building a lookalikes workflow to picking a lookalike API provider. And when it was opened, it usually drove the final call, over self-published GEO pages and vendor benchmarks with years of domain authority.<p>We&#x27;ve studied the effect and potential ROI of being benched, we&#x27;re taking OpenFunnel off the benchmark.<p>## What&#x27;s next<p>More GTM benchmarks, then beyond: devtools and infrastructure.<p>We&#x27;re are also working with traditional SaaS companies thinking about going API-first and opening up to a new class of customer: agents<p>Try it, or hand it to your agent: <a href="https:&#x2F;&#x2F;openbenchmarks.com" rel="nofollow">https:&#x2F;&#x2F;openbenchmarks.com</a>

Show HN: Ant – A JavaScript runtime and ecosystem Hello HN!<p>I&#x27;m the author of Ant, a JavaScript ecosystem built around a runtime with its own JavaScript engine. Ant also includes a package manager, the ants.land package registry, a platform for deploying and hosting applications, and Ant Desktop for building native desktop apps with web technologies, similar to Electron.<p>The goal is for these pieces to work as one coherent platform while remaining compatible with the wider JavaScript ecosystem. It&#x27;s still early, and I&#x27;d appreciate any feedback on the overall direction or what you&#x27;d like to see from an e2e alternative to the existing JavaScript stacks.<p>P.S. I’ve shared Ant here before as a runtime; since then, it has grown into the broader ecosystem you see today.
