The body is compact and free of obvious concept over-explanation, but several steps restate interpretive philosophy in prose ('Will it manifest here... Or in another state?') that could be tightened into direct instructions, leaving it mostly efficient rather than fully lean.

Steps give some concrete framing (named hexagrams, quoted line text, the 物莫能两大 principle) but rely on vague directives like 'Identify the ruling clan of the future state' and 'Read the relevant line texts' without a concrete method, matching the 'some concrete guidance but incomplete' anchor.

The Procedure is a clearly numbered 5-step sequence culminating in a dedicated Verification section with three explicit checkpoints confirming hexagram identification, framework coverage, and balance-principle application.

This is a short (under 50 lines) single-purpose skill with no bundle files and no need for external references; its well-organized sectioned structure (Overview, Procedure, Example, Expected Outcomes, Verification) meets the simple-skill bar for a top score.

Lists several concrete actions — 'hexagram transformation (本卦 to 之卦)', 'line text analysis', 'fulfillment location and timing determination', and 'clan affiliation prediction' — matching the anchor for multiple specific concrete actions.

It explicitly answers both what it does ('Covers hexagram transformation... line text analysis... clan affiliation prediction') and when to use it via an explicit 'Use when...' trigger clause, satisfying the highest anchor.

The 'Use when interpreting Zhou Yi (I Ching) hexagram readings or analyzing divination results' clause provides natural user-facing terms a user would actually say, with good coverage of variants (Zhou Yi, I Ching, hexagram readings, divination results).

The I Ching/Zhou Yi divination domain is a very narrow niche with distinct triggers unlikely to overlap with other skills, matching the 'clear niche with distinct triggers' anchor.
