harnessforge

What it does

harnessforge is a local, open-source harness generator for AI coding agents. Run uvx harnessforge init to scan a repo and generate the startup files agents read before coding: AGENTS.md, CLAUDE.md, Cursor rules, memory, skills, tools, and validators. Claude Code, Cursor, Codex, Gemini CLI, Aider, and others stay the brain — harnessforge lays down the project context.

Universal harness layer for AI coding agents — one command (uvx harnessforge init) sets up your repo for Claude Code, Cursor, Codex, Gemini CLI, Aider, and any other coding agent. - jcaiagent7143-ui/harnessforge

  Gambit, an open-source agent harness for building reliable AI agentsJan 2026 · github.com · ▲91

  Hey HN! Wanted to show our open source agent harness called Gambit. If you’re not familiar, agent harnesses are sort of like an operating system for an agent... they handle tool calling, planning, context window management, and don’t require as much developer orchestration. Normally you might see an agent orchestration framework pipeline like: compute -> compute -> compute -> LLM -> compute -> compute -> LLM we invert this so with an agent harness, it’s more like: LLM -> LLM -> LLM -> compute -> LLM -> LLM -> compute -> LLM Essentially you describe each agent in either a self contained…

  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…
