# localharness

Canonical URL: https://doramagic.ai/en/projects/localharness/

Source repository: https://github.com/ahwurm/localharness

## What it is

An open-source, model-agnostic agent harness for local LLMs. Define agents in YAML (tools, memory, deny-first permissions) and run them against any OpenAI-compatible endpoint: vLLM, Ollama, LM Studio, or llama.cpp.

## Capability boundary

skill, recipe, host_instruction, eval, preflight

## First safe verification

Verify the smallest path in an isolated environment and keep a rollback path.

## Main risk

Developers may fail before the first successful local run: Version banner reads stale install metadata on editable installs — shows old version after every source update
