The body is lean and directive with no concept over-explanation or padding — every line is a rule or checklist item, matching 'lean and efficient; every token earns its place'.

Concrete directives ("Update docs in the same PR as the code change", "Remove references to deprecated files, endpoints, or scripts") plus a specific verification checklist give actionable guidance; for an instruction-only skill the absence of code is not penalized.

The numbered Alignment Rules and explicit Verification checklist provide clear validation checkpoints, and per the simple-skills note a clear single-purpose skill can score 3 without a multi-step workflow.

The skill is under 50 lines with well-organized sections (When to Use, Alignment Rules, Verification) and needs no external references, satisfying the simple-skill exception for a top score.

"Documentation alignment rules for Engram" names a concrete domain and an action category, but does not list multiple specific actions, matching the 'names domain and some actions, but not comprehensive' anchor.

It explicitly answers both what ("Documentation alignment rules for Engram") and when (an explicit "Trigger:" clause), and the rubric only caps at 2 when trigger guidance is missing — which it is not. Not below 3 because the when is explicit rather than implied.

The "Trigger: Any code or workflow change that affects user or contributor behavior" clause supplies some relevant terms ("code change", "workflow change") but omits common natural variations a user would say ("docs", "API change", "documentation"), matching 'some relevant keywords but missing common variations'.

It is scoped to the Engram documentation niche, but the trigger "Any code or workflow change that affects user or contributor behavior" is broad and could overlap with other project skills, matching 'somewhat specific but could still overlap'.
