evidence-research skillA

evidence-research is agent-read markdown (skill) from rizwanzafaris/product-manager-os: Gather source-backed evidence with provenance. Use when a product decision needs claims separated from observations and open questions..

Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Evidence Research

Gather source-backed evidence, preserve provenance, separate observation from
inference, and mark missing evidence as open rather than inventing it.
