Better Harness is an open-source Harness Engineering platform for coding agents that lets you define harnesses as code, run controlled experiments, and inspect evidence. It integrates as a plugin or extension across hosts like Claude Code, Codex, Cursor, and Qoder, turning project and session evidence into prioritized improvements with verifiable next steps.

Use cases

• improve my coding agent workflow loop
• analyze claude code sessions for workflow improvements
• run controlled experiments on coding agent harnesses
• generate evidence-based reports of agent coding gaps
• compare outcomes across coding agent runs
• define agent harnesses as code
• get prioritized fixes with acceptance checks from agent sessions

When to choose

• You already use a supported coding agent host (Claude Code, Codex, Cursor, Qoder, Qwen Code, GitHub Copilot CLI) and want to improve the loop around it
• You want evidence-bounded, reviewable reports with impact, scoped repairs, and acceptance checks
• You need missing or partial evidence to stay explicit rather than guessed

When to avoid

• You need a general-purpose agent framework for building agents from scratch
• You use a coding agent host without an adapter (check the Host Adapter Matrix first)
• You want fully automated fixes without human review of evidence
