Conciseness

The body is dense and table/decision-tree driven with no explanation of concepts Claude already knows — word-count routing is a compact ASCII tree and Stage 2-6 is a single table. A few passages could still be trimmed: the 拆解边界声明 paragraph is long, and resume rules (Stage 写盘规则 / Step 4) partially restate what output-contract.md already holds. Anchor 4 (efficient, minor trimmable instances) fits better than 5 because of this redundancy, and better than 3 because there is no padded or generic filler.

Actionability

Guidance is fully concrete and executable: exact paths (拆文库/{书名}/原文/原文.md), the exact _meta.json initialization fields, verbatim user-facing question scripts in code blocks, and per-stage input/output/completion criteria (e.g. 「写作手法 ≥5 项维度」「爆点分析 6 维度齐全」「前50/100字」). For an instruction-only skill this matches the anchor-5 standard of copy-paste-ready, case-covering specificity; nothing below 5 is warranted since no key detail is left implicit.

Workflow Clarity

The pipeline is strictly sequenced (2 → 3 → 4 → 5 → 6 串行) with write-ahead progress tracking (_meta.json.last_stage_in_progress written before each Stage), explicit validation (备份完成后验证 原文/ 目录下文件非空 (>0 bytes); 目标文件写完、确认非空且长度合理后才 append), and a full feedback loop at the acceptance gate (任一阻断 → 回到对应 Stage 补写). This matches the anchor-5 example (validate → fix → re-validate → only-then-proceed) exactly; score 4 is ruled out because no checkpoint is implicit.

Progressive Disclosure

SKILL.md is a clear overview and all 15 bundle files in references/ are real and each referenced from the body, organized by a per-moment read-schedule table (Phase 1/Stage 2-3 vs Stage 4-6 vs 拆完后) with conditional reads (analysis-short-suspense.md / analysis-short-mechanics.md / analysis-characters.md / source-story-quality.md). References are one level deep — cross-links inside references are peer-level (e.g. quality-checklist.md → output-contract.md), not pointer chains, so the anchor-5 fit is clear; anchor 4 would require some unclear signaling, which is absent.

Specificity

The description lists six concrete analysis actions — 「拆解爆款短篇小说…的故事核、结构、情感线、反转设计、写作手法、共鸣层次」 — plus the concrete pipeline behavior 「跑完 Stage 2-6 产出完整拆文报告，落盘到 拆文库/{书名}/」. Coverage is comprehensive with zero vague filler, matching the anchor-5 example (multiple specific concrete actions) rather than 4, which would require a coverage gap.

Completeness

Both questions are answered explicitly: what — 「单一全量拆解管道：跑完 Stage 2-6 产出完整拆文报告，落盘到 拆文库/{书名}/」 — and when — 「触发方式：…『分析这篇短篇』——均进入同一管道」 with concrete trigger phrases. This mirrors the anchor-5 good example verbatim in structure; score 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Trigger coverage is exhaustive and natural: slash commands (/story-short-analyze、/短篇拆文) plus user utterances 「拆短篇」「拆这篇短文」「短篇拆文」「精细拆解短篇」「8000 字短篇拆解」「番茄短篇拆文」「故事会拆解」「盐言故事拆解」「分析这篇短篇」, alongside platform and genre synonyms (番茄短篇 / 故事会 / 知乎盐言 / 追妻 / 世情 / 重生 / 虐渣). This comprehensively covers synonyms and phrasing variations a real user would say, matching anchor 5; nothing on the 4 anchor's 'a few natural terms missing' applies.

Distinctiveness Conflict Risk

The niche is unambiguous — 短篇网文拆解 (short-form web fiction deconstruction) — and every trigger phrase contains 短篇/拆文/拆解 or a platform name, so overlap with sibling skills (story-short-write, story-short-scan, story-long-analyze) is minimal; the description even names the downstream skill story-short-write to delineate the boundary. Matches anchor 5 (clear niche, distinct triggers, minimal conflict risk); anchor 4's 'minor overlap risk' has no concrete instance here.
