Conciseness

The body is lean and assumes competence — compact syntax blocks with no explanation of what Obsidian or Markdown is — but the time-sensitive date "checked 2026-10-17" sits outside any 'old patterns'/'deprecated' section and the product-root resolution preamble is dense. Efficient overall with minor trimmable content; not 5 because a few tokens don't earn their place, not 3 because there is no padded or redundant explanation.

Actionability

Concrete, mostly copy-paste-ready guidance: full YAML frontmatter example, wikilink/embed/callout blocks, and executable commands (`python3 "$CORE" transaction inspect "$BUNDLE" --vault "$VAULT"`). Not 5 because the central mutation path (building the `claude-obsidian.transaction.v1` bundle) is deferred to an external reference rather than shown, leaving a minor gap.

Workflow Clarity

The vault-edit workflow is clearly sequenced with an explicit validation checkpoint for a destructive operation: draft → read operation-transactions.md → build bundle → "Inspect it, then set APPROVAL_SHA256 … after review" → apply, plus post-mutation lint ("Run deterministic wiki lint after a requested mutation and report remaining findings without silently repairing them"). This matches the anchor-5 pattern of explicit validation steps with a feedback loop.

Progressive Disclosure

Sections are well organized and the two references ([operation-transactions.md](../wiki/references/operation-transactions.md), [provenance.md](../wiki/references/provenance.md)) are clearly signaled one level deep with when-to-read context. Not 5 because both reference targets resolve outside the skill bundle under the product root (no references/ directory ships with the skill), so navigation depends on the external install layout; not 3 because references are clearly signaled, not buried.

Specificity

"Explain, draft, or validate" names three concrete actions, and the description enumerates ten specific syntax areas ("properties, wikilinks, embeds, callouts, tags, comments, highlights, block references, math, and Mermaid"), giving comprehensive coverage rather than minor gaps.

Completeness

Both parts are explicit: what ("Explain, draft, or validate Obsidian Flavored Markdown syntax: …") and when ("Use when the user explicitly requests Obsidian note formatting or syntax help, not for general Markdown or broad vault operations"), including a negative boundary. Matches the anchor-5 example structure.

Trigger Term Quality

Natural user phrasing is well covered: "Obsidian note formatting", "syntax help", plus domain keywords users actually say (wikilinks, callouts, tags, properties, embeds, Mermaid). No common variation is missing for this domain.

Distinctiveness Conflict Risk

A clear niche (Obsidian Flavored Markdown) with distinct triggers and an explicit exclusion of general Markdown and broad vault operations, so conflict risk with adjacent skills is minimal.
