$ARGUMENTS: Test pattern for the test step

Instructions

Run these first in sequence:

Run yarn prettier - format code (stop if fails)
Run yarn linc - lint changed files (stop if fails)

Then run these with subagents in parallel:

Use /flow to type check (stop if fails)
Use /test to test changes in source (stop if fails)
Use /test www to test changes in www (stop if fails)

If all pass, show success summary. On failure, stop immediately and report the issue with suggested fixes.
