Conciseness

Roughly half of the ~600-line body re-teaches standard CommonMark/GFM that Claude already knows: 'Basic Formatting' (headings, bold/italic, escaping), 'Lists' (unordered/ordered/tasks), 'Quotes', 'Code' (inline, fenced blocks), 'Tables', 'Horizontal Rules', and 'Footnotes' are all vanilla Markdown. Only the Obsidian-specific sections (wikilinks, embeds, callouts, properties, %%comments%%, tags, Mermaid linking) add information Claude cannot be assumed to know, so the padding guideline for known concepts puts this at 'noticeably verbose; several unnecessary sections'.

Actionability

Every construct is given as exact, copy-paste-ready syntax in fenced examples — wikilinks with heading/block targets, embeds with image sizing ('![[image.png|300]]'), foldable callouts ('> [!faq]-'), frontmatter property types, math, Mermaid — plus a 'Complete Example' showing the constructs composed into a real note. Examples cover all common cases with no gaps.

Workflow Clarity

This is a pure syntax reference with no multi-step process, sequencing, or decision guidance — there are no 'steps' at all, matching the 'sequence present but checkpoints missing or implicit' level at best. The 'Complete Example' section partially demonstrates how to compose a note, but there is no guidance for choosing between constructs or verifying output, and the under-50-line simple-skill exception does not apply to a 600-line reference.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), so the entire syntax reference is inlined monolithically in SKILL.md. Section headers give good in-page navigation and the closing 'References' section links official docs, but the GFM half of the reference clearly belongs in a separate file (or nowhere), matching 'some structure but content that should be separate is inline'.

Specificity

The description names the domain ("构建Obsidian知识库" — building an Obsidian vault) and several concrete capabilities ("带双向链接、Callout或Frontmatter的复杂笔记" — complex notes with wikilinks, callouts, frontmatter; "支持wikilinks与嵌入" — supports wikilinks and embeds), matching the 'names domain and 1-2 concrete actions' to 'several specific actions' range. However, marketing fluff ('精准生成' precisely generate, '完美支持' perfectly supports, '大幅提升...效率' greatly improves efficiency) pads the claims without adding concrete actions, keeping it below 4.

Completeness

Both 'what' ("使用此技能可精准生成标准Markdown文档，完美支持wikilinks与嵌入" — generates standard Markdown documents, supports wikilinks and embeds) and an explicit 'when' clause ("当需要编写带双向链接、Callout或Frontmatter的复杂笔记" — when needing to write complex notes with wikilinks, callouts, or frontmatter) are present. Not a 5 because the 'what' leans on vague intensifiers ('精准', '完美') instead of concrete trigger phrases for the full capability set.

Trigger Term Quality

Good keyword coverage with natural terms users would actually say: 'Obsidian', '知识库' (knowledge base/vault), '双向链接' (bidirectional links), 'Callout', 'Frontmatter', 'wikilinks', '嵌入' (embeds), 'Markdown'. A few natural terms are missing (vault, backlinks/双链, notes/笔记 as a standalone trigger, .md), matching the 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive 5.

Distinctiveness Conflict Risk

Obsidian-specific triggers (Obsidian, wikilinks/双向链接, callouts, frontmatter in a vault context) establish a clear niche, but the broad phrase "生成标准Markdown文档" (generate standard Markdown documents) overlaps with generic Markdown-writing skills, matching 'mostly distinct; minor overlap risk with closely related skills' rather than the minimal-conflict 5.
