Excerpt

Better Harness

Review the coding-agent system: context, execution, control, feedback, and learning; keep Sessions, project, and Agent assets independent.

Step 1: Resolve Scope and Collect the Evidence Bundle

Route:

<better-harness-fix-output>: Finding-bound Fix.
No callback plus leading fix, repair, or \u4fee\u590d: Manual Direct Fix.
Review/evaluation/reporting or mixed review-and-fix: Step 1.

Resolve the Skill path, <better-harness-root> as ../.., a supported <node>, and <cli> as <node> <better-harness-root>/scripts/better-harness.mjs. Stop if any owner is missing; never select another cache or runtime by search order.

This is the opening of the README. Read the full README on GitHub.
