Turn a signed PRD into epics, user stories, and acceptance criteria that a tester can run and a team can slice into releases. Use when a PRD or one-pager is approved and engineering needs a backlog, when stories in the tracker have no acceptance criteria, when a release plan cannot say which slice ships first, or when a story is too big to estimate. Takes the PRD, the personas, and the FRD where one exists; returns a story map, INVEST-checked stories with IDs, and given/when/then criteria in…
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.
What the file says
# Story Writer: from PRD to stories a tester can fail The backlog that fails Gate 2 was decomposed by feature, not by user behavior: stories are screens, criteria restate the story title, and the first release is whatever got built first. This skill decomposes along the user's journey, so every story names a behavior change, every criterion can fail, and the first release is a thin working slice, not a pile of finished parts. ## Files this skill drives - [../../templates/definition/user-stories.md](../../templates/definition/user-stories.md), the register where every story id is defined, split and INVEST-checked - [../../templates/definition/acceptance-criteria.md](../../templates/definition/acceptance-criteria.md), where every criterion lands with a permanent ID - [../../templates/definition/prd.md](../../templates/definition/prd.md), section 3, whose story table gets its criterion IDs here - [../../frameworks/prioritization/user-story-map.md](../../frameworks/prioritization/user-story-map.md), the map the stories hang on …

How to install
mdr add rizwanzafaris/product-manager-os/story-writer@sha256:0cac0260864f3914The line at the top of this page pins the label git:20260921.8135461, 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.
