Harness²

Google Research

Free

Google Research's open-source framework for recursive agent harnessing that refines an agent's prompts, tools and memory per task.

Task-Level Recursion: A contrastive Propose-Probe-Compose step proposes edits, probes their effects on the same task and composes a refined harness without ground-truth feedback.
Harnessing-Level Recursion: A persistent improvement harness is updated with adopted harnesses and evidence-supported lessons from each task.
Eight Editable Components: Exposes system prompt, guardrails, memory, tool guidance, subagents, skills, scripts and plugins as tunable parts.
Parallel and Sequential Modes: Scale the task-level recursion budget by exploring candidates in parallel or refining sequentially.
Multiple Executors: Run refinement with OpenCode and Codex executors.
Built-In Benchmarks: Setup and run commands for JobBench, LAB (legal work) and WorkBuddy Bench (office, web and code).
Credential-Free Demo: A local demo with deterministic editors runs both recursion modes without model credentials.

Agent Harness Research: Study how contrastive harness edits affect agent performance across benchmarks.
Improving Base Agents: Raise results of models such as GLM 5 and Gemini 3.5 Flash over their default harnesses.
Professional Task Evaluation: Evaluate agents on legal, office and coding tasks using bundled benchmark guides.
Tuning Coding Agents: Refine system prompts, skills and subagents for OpenCode or Codex executors.
Reproducible Experiments: Run, judge and report benchmark experiments with resume support.
