## Use and fit

The fdd skill reads an openAut telemetry schema. The repository explicitly identifies itself as a learning project not intended for production or occupied-building deployment. It does not fill an independent contractor's verified diagnostic procedure gap.

## Cost and access

Public source; its infrastructure and telemetry dependencies are substantial.

## Popularity and evidence

Repository snapshot: 1 star, 0 forks. No evidence of broad operational adoption.

## Reuse and package decision

Repository shows MIT. Kept link-only because execution scope and validation are unsuitable for the customer package.

Tools were not installed or operationally tested. Prices/counts may change. This is a research summary, not the product, connection, license grant or proof of field competence.
