#harness-engineering

HarnessRouter Community Edition: the self-hosted, Apache-2.0 edition of the unified interface for agent harnesses. Run Codex, Claude Code, Hermes, PI, DSH, and more through one API, with sessions, streaming, files, cancellation, and failure handling. Implements the Unified Harness Protocol (UHP), an open standard. Your keys, your infrastructure.

Attributed, resolvable artifact references for agent handoffs — a ~30-byte token instead of pasted context. MCP-native; the reference layer for the agent-harness world.

Your AI coding agent is only as reliable as the harness around it. Measure that harness in seconds with harness-score.

CubeLoop — a Pythonic, async-native agent harness core designed for high performance, readability, and production-grade persistence.

🔁 Build reliable recurring AI-agent systems: 1025 resources, 22 operational patterns, 22 loop contracts, 8 runtime starters, an interactive atlas, and a structured dataset.

Skill repository to enforce Engineering disclipline in coding assistants

Aielia — an open-source everyday chat assistant that runs a full 11-layer agent harness (world model, control-state gate, verification, recovery, learning) on every turn. Plus a visual canvas that compiles to LangGraph / CrewAI / Mastra / MS Agent Framework.

An interactive roadmap for harness engineering — building the agent loop, tool layers, context engineering, memory, retrieval, eval harnesses, and the rest of the scaffolding around modern LLMs.

Voice driven secure workstream management for Claude Code and Codex

Freelens Agent Bridge Extension

One desktop app for every coding agent. Pick the harness per session and any model it can reach.

The AI Agent Governance & Quality Engineering System.

Nightshift is an overnight AI agent harness that fixes bugs, manages TODOs, and implements features across your projects while you sleep, with a morning digest waiting when you wake up.

LLM-agnostic agent harness for trading futures on Claude Code, Codex, or Qwen Code, with a risk-gated order path and pluggable broker MCP servers (TopstepX default).

Octopus Agent — 基于 Harness 驾驭工程思想的多智能体管控调度框架

DevOS — Autonomous Enterprise Agent Network. Google All Things Agentic 2026, Track 3 (Fortified Enterprise Suite). Harness = Regras + Ferramentas + Memória + Skills + Verificações + Feedback Loops.

Deterministic regression tests for AI coding-agent behavior.

Hand a coding session from one agent to another without losing the thread — typed handoff briefs in your repo, lifecycle hooks that write and resume them on Claude Code, Codex and Antigravity, and CI-graded evals.

Evidence-governed harness engineering for agentic software development — mechanical gates over model consensus. Working paper + artifacts.
