The body is actionable but padded: the Purpose section repeats the frontmatter intent verbatim, Patton concepts (backbone, walking skeleton) are explained at length, and the Anti-Patterns and Common Pitfalls sections re-cover the same ideas (e.g., technical-architecture-as-backbone appears twice). It is mostly efficient but could be tightened, so it sits at score 2 rather than 3.

Provides concrete enumerated questions with exact option text, generated example maps, and a copy-paste-ready output markdown template, giving fully executable guidance.

A clear Step 0 → Q1–Q5 → Output sequence with explicit approve/modify/add-custom checkpoints at every question; the destructive-operation feedback-loop cap does not apply to this non-destructive facilitation skill.

It signals references to template.md and workshop-facilitation/SKILL.md, but those bundle files are absent, and the ~480-line body keeps concept tutorials, examples, and pitfalls inline that should be split into reference files—matching the score-2 "content that should be separate is inline" anchor.

Lists multiple concrete actions—"user story mapping workshop," "adaptive questions," and "structured map output"—rather than a vague domain label, matching the score-3 anchor of several specific concrete actions.

Explicitly answers both what ("Run a user story mapping workshop...") and when ("Use when you need backbone activities, tasks, and release slices for a workflow"), matching the score-3 what-and-when anchor.

Includes natural terms a PM would actually say—"story mapping," "backbone activities," "tasks," "release slices," "workflow"—giving good coverage rather than only technical jargon.

The story-mapping-workshop niche with backbone/tasks/release-slice triggers is distinct from generic backlog skills and unlikely to trigger for the wrong skill.
