Turn discovery evidence into the artifacts that name who the product is for and the job they are trying to get done: a job story, sourced personas, a journey map, and an opportunity solution tree. Use when Gate 1 needs personas built on real interviews, when an existing persona has gone stale or unsourced, when the team argues about what the user wants instead of what the evidence says, or when a journey map was drawn from the org chart rather than the user's day. Takes the evidence notes and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add rizwanzafaris/product-manager-os/persona-builder@sha256:bc48cf543cdf8b63The line at the top of this page pins the label git:20260919.72235e0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
