Conciseness

The body is mostly dense, useful reference material (function tables, syntax examples) with little concept-explanation fluff, but it repeats the same guidance multiple times — filter structures appear in 'Complete Schema', 'Filter Syntax', four 'Complete Examples', and again in 'Common Patterns', and duration arithmetic is covered in both 'Duration Type' and 'Date Arithmetic'. That duplication is unnecessary and could be tightened, matching the 'mostly efficient but could be tightened' anchor rather than the lean 5 or the padded 2.

Actionability

Everything is executable: a complete schema template, copy-paste YAML for every view type, and four full working base files (Task Tracker, Reading List, Project Notes, Daily Notes Index) covering common cases, plus concrete correct/wrong formula examples. This matches the 'fully executable; copy-paste ready; specific examples cover the common cases' anchor.

Workflow Clarity

There is no creation/edit workflow at all — the body jumps straight from a one-line overview into reference material, with no sequenced steps (gather properties → write YAML → verify) and no validation checkpoint (e.g., confirm the YAML parses or the base renders in Obsidian). That sits at the 'sequence present but checkpoints missing or implicit' level rather than 4; it is not 2 because the reference material itself is coherently organized by topic and the single task (write a valid .base file) is unambiguous in intent.

Progressive Disclosure

The skill has no bundle files at all (no references/, scripts/, or assets/), so the entire ~250-line functions reference, view-type specs, summary tables, and examples are inlined in SKILL.md — content that clearly belongs in separate files, which is the anchor-3 condition. It is not 2 because the body has clear, well-ordered section headers and ends with real external reference links, so navigation is possible; it is not 4 because essentially no content was split out of the main file.

Specificity

The description lists several concrete actions — '构建 Obsidian 数据库视图、配置过滤器或编写 YAML 公式' and '自动生成标准 .base 文件' with '表格/卡片多维展示与数据汇总' — matching the anchor for several specific actions with minor gaps (editing existing bases and embedding are not mentioned). It is not a 5 because promotional fluff ('轻松实现', '让知识库管理效率翻倍') pads the capability list rather than extending coverage.

Completeness

It explicitly answers both: what ('使用此技能可自动生成标准 .base 文件…实现笔记的表格/卡片多维展示与数据汇总') and when ('当需要构建 Obsidian 数据库视图、配置过滤器或编写 YAML 公式时' plus the audience/context '内容创作者与技术写作员在管理海量笔记时'), giving a clear what with concrete trigger phrases — the 5 anchor. The 4 anchor would require the when-clause to be less explicit, which it is not.

Trigger Term Quality

Natural trigger phrases are present: 'Obsidian', '数据库视图', '过滤器', 'YAML 公式', '.base 文件', '笔记', '表格/卡片' — good keyword coverage matching the anchor. It falls short of 5 because common user variations and synonyms (e.g., 'Dataview', 'base 文件/base 视图' alternates, or English phrasing a user might mix in) are missing.

Distinctiveness Conflict Risk

It occupies a clear niche — Obsidian Bases '.base 文件' with view/filter/formula triggers — and is unlikely to trigger competing skills. Not a 4 because the '.base' file format and '数据库视图' triggers are specific enough that even closely related Obsidian skills (e.g., Dataview note querying) would not be pulled in.
