Promptcellar

What it does

Promptcellar is an open-source Claude Code plugin that auto-logs every AI prompt you send into a structured JSONL file in your git repo (.prompts/). The conversations that produced your code now live next to your code, version with your code, and stay on your machine - readable with jq, redacted for secrets by default, in an open format (PLF) any tool can read or write. MIT-licensed.

An open framework for logging AI prompts to your repo. PLF format. MIT-licensed. Claude Code plugin available now.

Promptcellar logs every prompt you send to your AI agent into a structured, append-only file in your repo. Open format, open source, and yours forever — not your vendor's. Every commit your AI agent makes started as a prompt — a question, a correction, a “no, do it like this.” Today those prompts vanish into a vendor's database. Tomorrow you can't audit them, replay them, or learn from them. Promptcellar puts them in your repo, next to the code they produced. Trace any commit back to the prompt that produced it. Every record has the prompt, the git SHA, the files touched. Re-run a session against a different model or a fresh branch. The prompts are the script — the agent is the actor.

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
