Conciseness

Every line is operational with no padding or explanation of concepts Claude already knows — e.g. "Abort if the target path already exists" and "Do **not** run `setup-env-files.js` — it regenerates encryption keys". Rationale-bearing parentheticals ("walks `node_modules`/`.nx`, ~10s") convey failure modes and costs rather than background, fitting the anchor 'lean and efficient; every token earns its place'.

Actionability

Concrete, copy-paste-ready commands cover preflight (`git rev-parse --show-toplevel && git worktree list && git status --porcelain`), creation (`git worktree add -b <branch> <worktree-path> [<base-ref>]`), and submodule init, plus a worked `/worktree` example and a specific handoff tool (`move_agent_to_root`). It falls short of 5 because the env-copy step's actual recipe ("Use the fast `git ls-files` recipe in `nv-worktree-commands`") is deferred to another skill rather than shown, leaving a minor executable gap in step 3.

Workflow Clarity

Six clearly sequenced steps with explicit validation checkpoints and feedback loops: preflight abort ("Abort if the target path already exists"), a dirty-tree confirmation ask, enterprise skip conditions and failure fallback ("If enterprise setup fails, warn and continue in OSS mode — do not block the worktree"), and a final confirm checklist of what to report. This matches the top anchor; the operations are also non-destructive, so the missing-validation cap does not apply.

Progressive Disclosure

Well-organized sections with clearly signaled, one-level-deep references ("For git command details and path naming, read `nv-worktree-commands`"; "For cleanup, read `nv-worktree-cleanup`"). Not a 5 because this bundle has no reference files of its own and the dense `--enterprise` subsection (candidate clones, HTTPS fallback, symlink refresh) largely duplicates material that could live in the referenced `enterprise-submodule` skill.

Specificity

It lists multiple specific concrete actions — "Create a sibling git worktree and a new branch with the same name, copy local `.env` files, optionally initialize the enterprise submodule (`--enterprise`), and move the agent into the worktree" — comprehensively covering the skill's behavior with no vague filler. This matches the anchor for comprehensive concrete actions; it is not a 4 because there are no coverage gaps in the action list.

Completeness

Both halves are explicit: the 'what' is the concrete action list, and the 'when' is "Use when the user asks for a worktree, parallel branch checkout, or `/worktree` with a branch name" — concrete trigger phrases. This matches the top anchor exactly; a 4 would require the when-clause to be less specific than it is.

Trigger Term Quality

"worktree", "parallel branch checkout", and "`/worktree` with a branch name" are natural phrases a user would say, giving good keyword coverage. It stops short of a 5 because common variants like "git worktree", "isolated checkout", or "second copy of the repo" are absent, and it is above a 3 since the included terms are on-target rather than merely relevant.

Distinctiveness Conflict Risk

The trigger surface is a clear niche — worktree creation with named flags (`--enterprise`, `/worktree`) — making it unlikely to fire for unrelated skills. The named-skill triggers (`/worktree`, "parallel branch checkout") are distinct, matching the 'clear niche with distinct triggers' anchor.
