Conciseness

The body is almost entirely executable commands, defaults, and constraints with no conceptual padding — it never explains what Obsidian or git cloning is. Prose is limited to operationally necessary notes (e.g., the npm 'obsidian-cli' shadowing warning, the single-commit-timer caveat), so every token earns its place.

Actionability

Every step is copy-paste ready: concrete bash blocks with defined variables ($PROJECT_DIR, $VAULT_DIR), a defaults section, idempotent script invocation, and a GUI checklist for Step 5. It also covers the common error paths (missing Obsidian app, npm CLI shadowing, pre-existing claude_docs directory).

Workflow Clarity

Six clearly sequenced steps with explicit validation at nearly every stage: prerequisite checks (Step 1), main-branch verification (Step 2), a destructive-operation safety check that aborts before symlinking (Step 4), an end-to-end sync verification with cleanup (Step 6), plus a Success Criteria checklist. Error-recovery guidance is present (npm uninstall, back-up-and-abort), matching the top anchor.

Progressive Disclosure

Well-organized single-file structure (Role, When to Use, Defaults, Workflow, Constraints, Success Criteria) with all content being core workflow. However, at ~130 lines it exceeds the under-50-line case where sections alone suffice, and there are no reference files — detail like the plugin settings inventory in Step 3 could live in a reference, so this sits just below the top anchor.

Specificity

The description lists four concrete actions — 'Guides through cloning, installing plugins, symlinking claude_docs, and verifying the Obsidian CLI' — which is specific and actionable. It stops just short of anchor 5 because the workflow also includes opening the vault in Obsidian and verifying the sync flow, so coverage is not fully comprehensive.

Completeness

It explicitly answers both questions: what ('Guides through cloning, installing plugins, symlinking claude_docs, and verifying the Obsidian CLI') and when ('Use when setting up the shared atmosphere-vault Obsidian vault on a new machine or for a new team member') with concrete trigger phrasing.

Trigger Term Quality

Natural phrases a user would say are present: 'setting up the shared atmosphere-vault Obsidian vault', 'on a new machine', 'for a new team member'. Good coverage, but a few natural variations (e.g., 'onboard', 'sync', 'install Obsidian plugins' as standalone requests) are only implied, keeping it below the comprehensive-synonym anchor.

Distinctiveness Conflict Risk

It names a specific, niche target ('the shared atmosphere-vault Obsidian vault') with a clearly scoped use case (new machine / new team member onboarding), so it is unlikely to fire for unrelated skills.
