story-writer skillA
story-writer is agent-read markdown (skill) from rizwanzafaris/product-manager-os: 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 the.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

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 …
