Conciseness

Lean throughout: dense folder and rendering tables, exact tool and file names, and rules stated in a single line each ("A page links to at least two others"), with zero explanation of concepts Claude already knows. The only dates appear inside a legitimately instructional example of the measured-figure format, so no time-sensitivity penalty applies.

Actionability

Guidance is copy-paste concrete: named tools to avoid ("create_vault_file", "patch_vault_file", "search_and_replace"), an exact command ("grep -rn \"wiki/<old-folder>/<name>\" ."), exact frontmatter keys (title, tags, related, last-reviewed), and a ready-to-use markdown template for measured figures. Only a minor gap ("in the right section" of index.md is not enumerated), which keeps it from being an anchor-4 case with real missing steps.

Workflow Clarity

Seven clearly numbered, explicitly sequenced steps ("Follow each step before you finish the edit") with embedded rule-checkpoints like "Set last-reviewed to today on every page you touch" and "A page links to at least two others". Not 5 because there is no explicit final verification pass (e.g. re-check links, frontmatter, and index entry before finishing); not 3 since per-step rules function as implicit checkpoints and the sequence is unambiguous.

Progressive Disclosure

A single compact, well-sectioned file with no content that belongs in a separate file, and one clearly signaled one-level-deep external reference ("Invoke obsidian:obsidian-markdown before writing"). No bundle files exist, and none are needed at this size, so navigation is trivial.

Specificity

Names three concrete actions ("creating, editing or restructuring") and enumerates six specific coverage areas ("where edits must be made, the syntax skill to load, what renders on GitHub as well as in Obsidian, required frontmatter, linking a new page into the map, and how to write a measured number") that map one-to-one onto the skill's sections — comprehensive with no padding. Not 4 because no coverage area of the skill is missing.

Completeness

Explicitly answers both questions: "Use before creating, editing or restructuring any page under wiki/" is a concrete when-clause, and "Covers where edits must be made, the syntax skill to load, …" is a clear what. Not 4 because the when-clause is specific and trigger-shaped rather than generic.

Trigger Term Quality

Good natural keyword coverage — "wiki/", "Obsidian", "GitHub", "page", "frontmatter", "restructuring" — that a user would plausibly say. Not 5 because synonyms and file extensions users might naturally use ("notes", "vault", "documentation", ".md") are absent.

Distinctiveness Conflict Risk

The trigger is tightly scoped to "any page under wiki/ — the Obsidian vault for the whole monorepo", a clear niche with distinct triggers and minimal conflict risk against generic docs or markdown skills. Not 4 because the wiki/-path scoping leaves essentially no overlap with closely related skills.
