Conciseness

Lean runbook that assumes Claude's competence — no padding about what Obsidian, git, or symlinks are — with only minor trimmable prose in the Step 5 user instructions and a few explanatory code comments.

Actionability

Fully executable, copy-paste-ready bash blocks with real commands, guards, and verification echoes covering the common setup cases.

Workflow Clarity

Clear 6-step sequence with explicit validation checkpoints — prerequisite check, branch verification, symlink safety guard that exits on a real directory, and a sync-flow test — plus a Success Criteria checklist, appropriate for a destructive symlink operation.

Progressive Disclosure

Single-purpose skill under ~115 lines with no need for external references, well-organized into Role, When to Use, Defaults, Workflow, Constraints, and Success Criteria sections.

Specificity

Names three concrete actions — 'cloning, symlinking claude_docs, and verifying obsidian-cli' — giving specific, actionable coverage with only minor gaps (plugin configuration not mentioned in the description).

Completeness

Explicitly states both what ('Guides through cloning, symlinking claude_docs, and verifying obsidian-cli') and when ('Use when setting up ... on a new machine or for a new team member'), but the trigger-phrase list is not as exhaustive as the score-5 anchor.

Trigger Term Quality

Includes natural phrases a user would say ('setting up', 'new machine', 'new team member', 'Obsidian vault'), though common synonyms like 'onboard' or 'install' are absent.

Distinctiveness Conflict Risk

Targets a clear, narrow niche — the shared 'atmosphere-vault Obsidian vault' setup — with distinct triggers and minimal risk of firing for unrelated skills.
