User Story Generation Skill

Use When

decomposing approved features into INVEST user stories, epics, story points, and initial acceptance criteria; use acceptance-criteria when stories already exist and only test oracles are needed.
Use this procedure when the required source artefacts are available and User-story backlog and story map is the next lifecycle deliverable.

Use acceptance-criteria when that neighbouring route owns the decision or deliverable.
Do not invent missing project evidence, standards clauses, thresholds, or stakeholder decisions.

Artefact	Source or provider	Required?	Behaviour when missing
Vision, feature catalogue, personas, glossary, and quality targets	Project `_context/` and product owner	Yes	Stop the affected step, name the missing source, and return only a qualified gap record.
