In the nature of Open Source, I am releasing something I'm actively working on but is insanely simple and will likely be made anyways. It is an SDK for scripting Claude Code. It's a lightweight (155 lines) and free wrapper around claude code This is a big deal because it seems that using claude code and cursor has become largly repitive. My workflow typically goes like this: Plan out my task into a file, then have claude code implement the plan into my code. I'm actively building a product with this, but still wanted to make it OSS! Use it now with `pip install codesys`

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
