The body is dense and assumes Claude's competence — it never explains what git, gh, PRs, or diffs are — and each section earns its place; not 2 because there is no unnecessary concept explanation or padding to tighten.

Provides concrete, copy-paste-ready commands (gh issue/pr view, gh pr diff, git log, rg) and a literal output template with filled fields; not 2 because the guidance is executable rather than pseudocode or abstract direction.

The Issue Review Shape is a numbered 1–5 sequence with explicit checkpoints (check whether main already fixes it, reproduce/proof) and an error-recovery branch ('if reproduction is not feasible, say what blocks it'); not 2 because validation/feedback steps are explicit rather than implicit.

No bundle files exist, and the single body is organized into clearly labeled sections (Start, Review Contract, Code Reading Depth, Provenance, Fix Quality Bar, PR/Issue Review Shape, Output Template) with no nested references; not 2 because navigation is clear and content is well-split by section rather than a monolithic wall.

Names the domain and multiple concrete actions — "bugs, PRs, best fix, stale-or-real, read code first" — matching the anchor that lists several specific concrete actions; not the level below because it goes beyond naming a domain to enumerating distinct review tasks.

Clearly states what the skill does but has no explicit "Use when..." trigger clause, so "when" is only implied; capped at 2 per the guideline on missing trigger guidance, and not 3 because both what AND an explicit when are required.

Uses natural terms a user would actually say — "GitHub", "bugs", "PRs", "review", "fix" — giving good coverage; not below because the core terms are common user vocabulary rather than obscure jargon.

Carves a clear niche — evidence-first, code-aware GitHub review — with distinct triggers unlikely to fire for unrelated skills; not 2 because the domain and posture are specific rather than broadly overlapping.
