Harness Manager has launched as a free and open-source macOS control center for discovering, installing, and managing AI coding harnesses, MCP servers, and skills.

Harness Manager is an open-source macOS application designed as a unified control center and app store for local AI coding setups. Built by Sebastian Solano, the tool simplifies discovering, installing, and updating AI harnesses such as Claude Code, Codex, OpenCode, and Pi. It automatically inspects the local machine to detect installed tools, manage Model Context Protocol (MCP) servers and reusable agent skills, check system paths and versions, and troubleshoot misconfigured environments.

// ANALYSIS

The explosion of CLI-first coding agents and MCP servers has created configuration sprawl, making a dedicated local control plane a natural evolution for modern developer workstations.

• Centralized stack management: Consolidating disparate agent harnesses, CLI tools, and background processes under a single GUI eliminates the friction of manually tracking multiple configs and terminal sessions.

• MCP and skill orchestration: Native discovery and lifecycle management for MCP servers and agent skills bridge the gap between isolated tools and cohesive developer workflows.

• Platform and maturity constraints: Limited currently to macOS 14+ and distributed as an unnotarized preview, the app will need cross-platform support and verified trust before achieving broad enterprise or community adoption.

REFLEX cuts strong-model calls with Jev

REFLEX adds Jev as a fast, typed decision layer for LLM agents, escalating to a stronger model only when confidence is low or generation is needed. It reached 95% task success while reducing strong-model calls by 72.7% on a frozen 100-task benchmark.

Motion adds Three.js, vgpu support and demos

Motion (formerly Framer Motion) announced public availability for its integrations with Three.js and Matias's vgpu WebGPU library, releasing two Zelda-themed interactive watercolor diorama demos. The showcases—an Ocarina of Time scene powered by Three.js and a Majora's Mask diorama running on vgpu—illustrate how Motion's declarative animation primitives, spring physics, pointer parallax, and reactive motion values can be used directly within WebGL and WebGPU rendering contexts to create seamless, high-performance 3D visual effects.

PrismaX opens robotics teleoperation datasets to AI teams

PrismaX has opened access to its real-world robotics teleoperation dataset for AI training teams developing physical AI and foundation models. Backed by a16z crypto, the San Francisco-based startup coordinates human teleoperators, robot hardware owners, and AI researchers to record, validate, and aggregate demonstration trajectories across complex manipulation tasks.
