Could you build this?
Partial The Node.js SDK that wraps functions, collects call counts, and displays per-feature dashboards is achievable with vibe coding. Credible energy and carbon estimates require a defensible energy model and calibration, which is specialized knowledge.
What it would actually take: Build an instrumentation SDK (wrapping functions with timing and resource counters) and a time-series backend with a dashboard. The core difficulty is converting runtime measurements into energy and carbon estimates, which needs published power models, hardware and region carbon intensity data, and ideally an expert in green software to validate the methodology.
