principle-explain-the-number

by pstack-claude

Apply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.

Frequently asked questions about principle-explain-the-number

What does the principle-explain-the-number skill do?
