Conciseness

The body is dense and almost every line is non-obvious operational guidance (directory layout, expert sizing, parallel dispatch, restraint rules for verifiers, anti-synthesis-trace rules). It is not 5 because the opening "这个 skill 在做什么，为什么这么设计" section spends three paragraphs on motivational rationale ("一个人再聪明，也很难同时是经济学家、工程师和心理学家") that could be trimmed to a few bullets; it is not 3 because there is no explanation of concepts Claude already knows and no filler padding.

Actionability

Guidance is concrete for an orchestration skill: exact run directory `markdown/multi-expert/<主题slug>-<YYYYMMDD>/` with subdirectories, per-expert output paths `experts/NN-<角色>.md`, verifier outputs `review/fact-check.md` and `review/red-team.md`, explicit agent-selection rules (use domain subagent if present, else general-purpose role-play), and explicit parallelization instructions. It is not 5 because a few operational details (e.g., what the orchestrator reports back, how many experts to pick when in doubt) remain implicit and depend on the referenced files; not 3 because there is no pseudocode-level vagueness.

Workflow Clarity

The 8-step workflow is clearly sequenced with explicit gating ("等所有专家写完", "两个校验器都完成后，才动笔写最终文章"), explicit parallelization opportunities (steps 5-6 in one message, all experts in one message), and a built-in feedback loop: experts must "交稿前自我验证一轮（不通过就改到通过）". This matches the 5 anchor 'clear sequence with explicit validation steps; feedback loops', and the operations are non-destructive so no destructive-cap applies.

Progressive Disclosure

The body is a lean overview; all three referenced files (references/expert-brief.md, verifiers.md, synthesis.md) exist in the bundle, are referenced at their point of use in the workflow, and are summarized with one-line descriptions in the 参考文件 section. References are exactly one level deep (verified: no nested .md references inside the bundle files), matching the 5 anchor 'clear overview with well-signaled one-level-deep references'.

Specificity

The description lists multiple concrete actions: "先判断问题涉及哪些领域，召集对应的领域专家分别搜证、按第一性原理作答（图文并茂、有权威数据和案例、讲清适用边界与证伪方式、自我验证）", plus fact-check, red-team verification, synthesis into a first-person article, and output location "当前项目 markdown/ 目录". This matches the 5-anchor 'multiple specific concrete actions; comprehensive coverage' and cannot be 4 since no capability area is left unenumerated.

Completeness

Both 'what' (multi-expert first-principles analysis, dual verification, synthesized article, output location) and 'when' (explicit "触发条件：" section with concrete trigger phrases and example utterances) are clearly and explicitly stated. Not 4, because the 'when' is not merely present — it is fully explicit with concrete trigger phrases, exactly the 5-anchor example pattern.

Trigger Term Quality

It quotes many natural user phrases users would actually say: "帮我分析一下……" "这个问题到底怎么回事" "从多个角度看……" "深度思考一下……" "这事儿靠谱吗" "为什么会……未来会怎样", covering synonyms and variations. This is comprehensive natural-term coverage matching the 5 anchor, not merely 'good coverage with a few missing' (4).

Distinctiveness Conflict Risk

The methodology (multi-expert, fact-check, red-team, falsification paths) is distinctive, but the claim "解答任何领域的棘手问题" plus "即使用户没有明说……只要问题棘手、值得认真拆解，也应使用本 skill" makes the trigger space extremely broad — generic phrases like "帮我分析一下" or "深度思考一下" overlap heavily with general analysis/research/deep-research skills. It fits 'somewhat specific but could still overlap with similar skills' (3) better than 'mostly distinct; minor overlap risk' (4), because the catch-all capture clause invites conflicts with any analytical skill.
