Conciseness

Lean and efficient throughout; the opening quote and the two compact tables (four rules, routing table) each earn their place and assume Claude's competence. Not 4 because there is no over-explanation or padding left to trim.

Actionability

Highly actionable routing table (situation -> which skill) and the four-rule table (rule -> 做法 -> 违反信号) give concrete decision guidance; code absence is not penalized for an instruction-only methodology skill per scoring_notes. Not 5 because some guidance ('认真，但不机械') is aphoristic rather than concrete.

Workflow Clarity

Clear routing sequence with discipline checkpoints (调用纪律: one main skill at a time, defer to host flows, no mechanical invocation). Not 5 because checkpoints are implicit with no explicit validate->fix->retry loop; not 3 because most checkpoints are present and the operation is not destructive/batch, so the cap-at-3 rule does not apply.

Progressive Disclosure

A single self-contained ~50-line file with well-organized sections and no nested references; the under-50-line simple-skill exception applies. References to downstream skills are names rather than file links, which is appropriate for this overview router.

Specificity

Names the methodology-router domain and ~2 concrete actions ('enforce seek truth from facts', 'route to a downstream skill only when it clearly helps') but not a comprehensive multi-action list. Not 4 because only two actions and clear coverage gaps; not 2 because it goes beyond merely naming the domain.

Completeness

Both 'what' (entry point/governing principle enforcing Qiushi + routing) and 'when' ('Load once at the start of a top-level session'; skip for narrow sub-agents) are explicit. Not 5 because the 'when' is session-mechanism-flavored and lacks concrete task-trigger phrases; not 3 because 'when' is explicit rather than merely implied.

Trigger Term Quality

Trigger phrasing is mechanism-speak ('Load once at the start of a top-level session', 'route ... only when it clearly helps') rather than natural task keywords a user would say; the concrete trigger terms (investigation, contradiction analysis, etc.) live in the body, not the description. Not 3 because even common variations are absent from the description.

Distinctiveness Conflict Risk

Clear niche as a methodology entry-point/router with an explicit skip rule for narrow sub-agents, giving minimal conflict risk. Not 5 because trigger distinctiveness relies on the body rather than the description itself.
