Conciseness

Lean, dense, and assumes Claude's competence: it gives git rev-parse commands without explaining what a worktree is, with no padding or restatement of known concepts; every section earns its tokens.

Actionability

Provides copy-paste-ready, executable bash commands (git rev-parse --absolute-git-dir, --show-superproject-working-tree, --show-toplevel, etc.) covering the detection and reuse cases, plus a concrete result-contract template.

Workflow Clarity

A clear numbered Step 0→1→2 sequence with explicit decision branches and a blocked-state contract; however creation/destructive operations are routed to separate docs and the in-file steps include only detection validation, not a validate-then-retry loop for the actual destructive checkout.

Progressive Disclosure

It routes to three one-level-deep references (claude-code.md, harness-native.md, git-only.md), but those referenced files are not present in the bundle, so the disclosure structure cannot be verified and the body inlines routing logic that depends on missing files.

Specificity

Lists several concrete actions — 'Establish or reuse an isolated Git worktree', 'create or enter a worktree' — but reuses overlapping verbs for a single capability rather than enumerating multiple distinct actions, leaving minor coverage gaps.

Completeness

Explicitly states what it does (establish or reuse an isolated Git worktree) and when to use it ('Use whenever the user asks to create or enter a worktree... wants parallel work... or another workflow requires Git checkout isolation').

Trigger Term Quality

Covers the natural terms a user would say — 'worktree', 'separate Git checkout', 'parallel work', 'branch, PR, tag, or commit', 'Git checkout isolation' — with strong synonym coverage.

Distinctiveness Conflict Risk

It targets a clear niche (Git worktree isolation) with distinct triggers, but the broad phrase 'parallel work without disturbing the current checkout' could lightly overlap with generic branch/checkout skills.
