Conciseness

The body is lean and assumes Claude's competence — a terse goal statement, an input table, and step commands with no git-concept explanations; warnings carry real signal ('it regenerates encryption keys'). Every token earns its place, matching the 5 anchor rather than 4 because there is no over-explanation left to trim.

Actionability

Mostly executable: 'git worktree add -b <branch> <worktree-path> [<base-ref>]', the preflight command trio, the submodule block, and 'pnpm symlink:submodules || echo "WARN: ..."' are concrete. Two executable details — the .env* 'rsync recipe' and the sanitized-name path rule — are deferred to nv-worktree-commands rather than given inline, so it is not fully copy-paste ready from this file alone.

Workflow Clarity

Six clearly sequenced steps with explicit validation ('abort if the target path already exists', dirty-tree warning with user confirmation), error-recovery fallbacks ('warn and continue in OSS mode — do not block the worktree'), and a final confirm checklist. This matches the 5 anchor; it is above 4 because checkpoints are explicit and complete rather than mostly present.

Progressive Disclosure

The SKILL.md is a well-structured overview that defers detail one level deep with clearly signaled references ('For git command details and path naming, read nv-worktree-commands. For cleanup, read nv-worktree-cleanup.'). However, none of the referenced files (nv-worktree-commands, nv-worktree-cleanup, enterprise-submodule) exist in this bundle — there is no references/ directory — so the deferred details are not reachable from the bundle itself, a minor organization gap that fits the 4 anchor.

Specificity

The description lists multiple specific concrete actions — 'Create a sibling git worktree and a new branch with the same name, copy local .env* files, initialize the enterprise submodule, wire enterprise symlinks, and move the agent into the worktree' — with comprehensive coverage of the skill's behavior. This matches the 5 anchor; it is not 4 because there are no meaningful gaps in the action coverage.

Completeness

It explicitly answers both what (the full concrete action list) and when ('Use when the user asks for a worktree, parallel branch checkout, or /worktree with a branch name') with concrete trigger phrases. This matches the 5 anchor; it is not 4 because the when-clause is already explicit and multi-trigger.

Trigger Term Quality

Good natural keyword coverage: 'worktree', 'parallel branch checkout', and '/worktree with a branch name' are phrases users would plausibly say. A few natural variations are missing (e.g. 'git worktree', 'new worktree', 'check out a branch in parallel'), which fits the 4 anchor rather than the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

It occupies a clear niche (worktree creation plus .env copying, enterprise submodule wiring, and agent handoff) with distinct triggers including a slash-command trigger, so the risk of firing for the wrong skill is minimal. Matches the 5 anchor.
