Lean body that assumes competence and does not explain concepts Claude already knows; the one-line Overview is the only mild redundancy with the description, well below the verbose 2-anchor.

Concrete specifics exist (三牢, named animals, named deities, historical examples), but the core 'Conduct the Ritual' step is abstract ('Perform sacrifice according to established rites') with missing key details, fitting the some-concrete-but-incomplete 2 anchor rather than copy-paste-ready 3.

Five clearly sequenced steps plus a dedicated Validation section with explicit checkpoints (verify occasion, confirm animal standard, check documentation), matching the clear-sequence-with-validation anchor; not the 2 anchor because checkpoints are explicit.

Under 50 lines with no external references needed and well-organized sections (Overview, Steps, Examples, Expected Outcomes, Validation), which the rubric notes can score 3 for simple skills.

Lists multiple concrete actions — 'Guides altar preparation, sacrificial animal selection (三牢), ritual conduct, and event documentation' — matching the multi-action anchor rather than the single-domain anchor at 2.

Explicit 'Use when...' clause answers when, and the action list answers what, satisfying the both-what-and-when anchor; missing the trigger would cap at 2, but it is present.

Natural trigger phrases users would voice are present ('state sacrificial rituals', 'establish religious legitimacy', 'mark significant occasions'); not generic jargon, so above the 2 anchor.

The niche 'state sacrificial rituals (畤)' with Qin-specific terminology is highly distinct and unlikely to trigger for unrelated skills, matching the clear-niche anchor.
