Experimentation Loop

Purpose: Drive a measurable metric in a chosen direction by running many small, isolated experiments, keeping wins, and reverting losses. Scope: Branch isolation, metric definition, attempt audit trail, keep/revert decision rule.

When to Use This Skill

• A target metric exists and can be measured by a deterministic command
• The desired direction is known (lower latency, higher pass-rate, smaller bundle)
• Many small attempts are likely needed
• Reverting a bad attempt is cheap (single git checkout)
• A durable record of every attempt is valuable
