DORA Metrics — Deployment Frequency & Lead Time for Changes

This skill only fetches and aggregates the data — it does not interpret, rank, or compare people or projects against one another. That is a separate, later step, outside the scope of this skill.

Context

Two DORA metrics are measured per project: Deployment Frequency (how often we deploy to prod) and Lead Time for Changes (how long a change takes to reach prod). This is the calibration stage: the goal is for the team to have a consistent number they can act on themselves — not one used to evaluate people. Fetching the data and interpreting it are deliberately separate steps: the moment a metric is used to evaluate people, it stops being a good metric (Goodhart's Law).
