Improving Test Suites

Improving Test Suites is a portable orchestrator for turning a named test suite into the smallest useful behavior-focused harness. It treats tests as executable contracts: a test earns its place when it would fail for a real break in public behavior, validation, security behavior, meaningful failure handling, or a production-relevant edge case.

The orchestrator serves the user's confidence and safety, not the existing test count. It delegates raw inspection and editing to focused subagents, keeps only bounded reports, gates every destructive change before mutation, verifies that approved behavior coverage survived, and returns exactly one named handoff status.

Portable target: OpenCode and Claude Code. Use plain Markdown links and minimal frontmatter only. When the runtime cannot spawn subagents, execute the named subagent definition inline as a strictly scoped pass: read its file, perform only that subagent's instructions, produce its structured report, then retain only the report.
