Better Harness

See how your AI coding workflow works—and make it better, one step at a time.

Better Harness reviews how coding agents understand tasks, make changes, verify results, deliver safely, and learn—then shows what to improve next, with every finding tied to visible evidence.

See it in action

Ask /better-harness to review the current task and its surrounding project Harness. The report keeps missing evidence explicit and turns supported gaps into prioritized findings with an impact, expected output, scoped repair, and acceptance checks.

How Better Harness works

Better Harness combines feedforward guides (AGENTS.md, specs, Skills, acceptance criteria) with feedback sensors (linters, tests, Hooks, review agents), and evaluates five parts of delivery—the Agent Work Loop:

Task Understanding

Does the agent know the goal and what “done” means?

Controlled Execution

Is the work on supported, repeatable paths?

Change Validation

Is there evidence the change actually works?

Reliable Delivery

Does AI speed bypass quality checks or acceptance?

Learning Capture

Does the next task benefit from this one?

Better Harness architecture: host integration, three independent evidence agents, unified analysis by one lead agent, findings, host outputs, and repair

Three evidence domains stay independent until unified analysis; every result retains a visible evidence source, owner, and validation route.

Quick start

Pick your coding agent—you can be looking at your first report in minutes. Once installed, ask for the host's durable report:
