Harness Starter Kit is an open-source agent orchestration boilerplate developed by harnessworks. It provides a standardized baseline repository layout, command infrastructure, and universal agent skill packages designed to scaffold, evaluate, and deploy customized autonomous coding agent workflows. In day-to-day operation, the kit establishes a structured environment comprising specialized command definitions (`commands/`), reusable agent skills (`agent-skills/`), and continuous benchmarking suites (`benchmarks/`). Developers configure tasks, evaluate agent execution against built-in benchmark oracles, and attach modular skills using project-level configuration stored in `.harness`. Unlike monolithic standalone CLI agents, Harness Starter Kit focuses on the scaffolding layer required to build and evaluate custom agents. It decouples core agent capability modules into explicit, testable skills while integrating standardized benchmarking tools directly into the development cycle. Distributed as an open-source project on GitHub under the harnessworks organization, the starter kit is actively tagged with semantic releases and versioned packages.

agent-skills directories. - Integrated benchmarking framework — Provides built-in benchmark suites and oracle validation tooling to measure agent accuracy and task completion. - Standardized command infrastructure — Defines reproducible command interfaces for orchestrating agent interactions from the terminal. - Project-level .harness configuration — Houses orchestration manifests and agent run parameters in a localized directory structure. - Pluggable agent harness architecture — Decouples model execution logic from tool definitions, enabling custom orchestration pipelines.agent-skills package allows teams to define specific file operations, refactoring routines, or tool integrations that agents can call.benchmarks suite to run standardized test scenarios against their agent logic. Automated oracle checks evaluate whether agent runs successfully resolve code modification tasks without regressions.This starter kit is designed for AI engineers and developers building custom CLI agent workflows, modular agent skills, or benchmark suites for autonomous coding systems. It is not intended for end users looking for an out-of-the-box turnkey interactive coding assistant with a finished GUI.
