metaharness vs ruflo
metaharness: MetaHarness is a CLI and browser Studio that mints custom AI agent harnesses from any GitHub repository, creating a repo-aware CLI, coding agent, and local MCP server tailored to the project. It acts as a factory for agent frameworks, allowing users to ship their own branded, npm-publishable AI agents with custom memory, governance, and model routing.; ruflo: Ruflo v3 is an enterprise AI orchestration platform for Claude-based multi-agent swarms, closely related to Claude Flow. It features an inter-agent consensus algorithm, vector database integration for persistent memory, self-learning workflows, and native Claude Code SDK integration. Designed for deploying autonomous agent pipelines at scale with shared state management.

When to choose:
- You are a heavy Claude Code or Codex user and want several agents coordinated on one task, with memory across sessions.
- You want a console that tracks cost and tokens and lets you replay and compare runs.
- You want control levels (read, write, manage, full) with ask or auto approval.
When to skip:
- You want a light setup: the full CLI install adds many files and hooks to your workspace.
- You cannot read mods before installing: they run with your permissions and are not sandboxed.
- Context overhead matters: hundreds of MCP tools and many commands mean a steep learning curve.

Features
metaharness01Custom AI Agent Harness Generation: Mints custom AI agent harnesses from any repo, complete with a repo-aware CLI and local MCP server.
02Repo Scoring & Cost Estimation: Scores any repository to assess harness fit, build likelihood, tool safety, and estimated cost per run before scaffolding.
03Model Routing & Optimization: Automatically routes requests to the cheapest model that meets quality standards, and supports training on custom data for better cost efficiency.
04Self-Evolving Harness (Darwin Mode): Enables the harness to mutate its own configuration, test changes in a sandbox, and keep only measurable improvements for continuous evolution.
05Multiple Host Compatibility: Supports deployment and execution on nine different agent hosts, including Claude Code, OpenAI Codex, pi.dev, Hermes, and GitHub Actions.
ruflo01Adds a large set of specialised agents, commands, skills, hooks and an MCP server around Claude Code and Codex
02Agent swarms that self-organise and coordinate in the background through hooks
03Memory across sessions with local vector retrieval and learning from past runs
04Visual console to track workflows, agents, models, tokens and cost, with replay of runs
05Federation for agents on different machines to communicate
