The body is lean: a brief framing paragraph plus a tight four-step list, with no padding or explanation of concepts Claude already knows. Every token earns its place.

Steps give concrete, copy-pasteable guidance with specific example paths (e.g. 'sdk/search/Azure.Search.Documents/.github/skills/') and concrete fallbacks (.github/CODEOWNERS), which is actionable even though no code is required for this instruction-only skill.

The discovery process is a clearly sequenced four-step list with explicit conditional branching ('If it exists' / 'If no ... directory exists'); this is a low-risk lookup task that needs no validation checkpoint, so the clear sequence and fallback earn the top anchor.

This is a short single-purpose skill with well-organized sections and no external bundle files needed; per the rubric's simple-skill note, well-organized sections suffice for the top score.

Names the domain ('package-specific domain knowledge') and actions ('Discovers and loads'), but these are generic verbs rather than a list of multiple concrete capabilities, so it does not reach the 'multiple specific concrete actions' anchor.

It states what the skill does ('Discovers and loads package-specific domain knowledge') and provides an explicit 'WHEN:' trigger clause, clearly answering both what and when.

The 'WHEN:' clause enumerates natural trigger phrases users would say ('add feature to package', 'fix bug in package', 'modify package code', 'change client library'), giving good coverage of natural terms.

It is scoped to a clear niche ('packages under sdk/') with distinct triggers, making it unlikely to fire for unrelated skills.
