Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k This started based off of a hunch. We usually use OpenCode, but were &#x27;forced&#x27; to use Claude Code for a while due to issues with Meridian. In that time, we saw the usage meter rise much, much more quickly than when using OpenCode.<p>This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:<p>We added logging between the agentic coding tool (Claude Code and OpenCode) and Anthropic&#x27;s endpoint, and captured all requests (and the returned usage blocks).<p>With one caveat (toward the end of the post) we found unambiguously that Claude Code was far more inefficient in terms of its cache strategy and its harness token usage than OpenCode.

Show HN: Kurvengefahr – browser CAD/CAM for pen plotters A few years ago I made a pen plotter attachment for Prusa MK4 (<a href="https:&#x2F;&#x2F;www.printables.com&#x2F;model&#x2F;827264-pen-plotter-attachment-for-prusa-mk4" rel="nofollow">https:&#x2F;&#x2F;www.printables.com&#x2F;model&#x2F;827264-pen-plotter-attachme...</a>) and at the time I didn&#x27;t have a good way to turn artwork into G-code for it, and I put the project on ice for a while.<p>I recently wanted to dabble in line art again and made a small browser app to make it easier. As agentic AI tools of 2026 are quite addictive, it rather quickly grew into something quite a bit more - an integrated browser CAD&#x2F;CAM for pen plotters that covers everything from importing existing artwork, creating artwork from scratch, preparing for plotting and hardware integration. It includes some off-beat features like a Logo interpreter for turtle art and Graves RNN for handwriting synthesis and in addition to 3D printer pretending to be pen plotters it now also supports actual pen plotters based on EBB (AxiDraw) and GRBL firmwares through Web Serial.<p>If you own an AxiDraw or a GRBL plotter, I&#x27;d very much appreciate it you gave it a try and give feedback. As I don&#x27;t own those, I did all the testing with a hardware mock on STM32, so I am not sure how well it works attached to an actual plotter.<p>Source code and docs are on GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;tibordp&#x2F;kurvengefahr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tibordp&#x2F;kurvengefahr</a>

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?
