Conciseness

The body is lean and every token earns its place: it conveys only non-obvious, repo-specific knowledge (gitignored-file behavior, measured timings "~11s vs ~0.1s", the STORE_ENCRYPTION_KEY trap in setup-env-files.js) and never explains concepts Claude already knows. It is not 4 because there are no sections that could be trimmed without losing decision-relevant information.

Actionability

Commands are copy-paste ready and cover the common cases: `git worktree add -b <branch> <worktree-path>`, the `git ls-files -z -o -i --exclude-standard --directory | rsync -a --from0 --files-from=-` pipeline, and the --lite loop. The only pseudocode, `sanitize(BRANCH)`, is immediately defined ("lowercase; `/` → `-`"), so this fully matches the executable anchor.

Workflow Clarity

Sections follow a logical create→inspect→copy→remove sequence with real checkpoints ("Abort if `WORKTREE` already exists", "report the list that was sent", "use `--force` only when the user explicitly asks" guarding the destructive remove). It is not 5 because there is no explicit post-create verification step or error-recovery loop, and not 3 because validation guidance for the risky operations is explicitly present.

Progressive Disclosure

This is a ~100-line single-use reference correctly kept in one file with well-organized sections and no content that belongs in a separate file; navigation is easy and cross-references to sibling skills (nv-worktree-create, nv-worktree-cleanup) are clearly signaled. There are no bundle files to misplace, and nothing is buried.

Specificity

"path naming, create/remove/prune, `.env` copy and cleanup" lists several concrete capabilities, matching the anchor for several specific actions with minor gaps; it falls short of 5 because the description omits actions the body covers (inspect, remove guidance, anti-patterns).

Completeness

"Git worktree command reference: path naming, create/remove/prune, `.env` copy and cleanup" clearly states what it does, and "Use when implementing or debugging worktree setup" explicitly states when, with concrete trigger scenarios; it exceeds anchor 4 because the when-clause is explicit and specific rather than improvable.

Trigger Term Quality

"git worktree" and "worktree setup" are exactly the natural phrases a user would say when needing this skill, giving good keyword coverage; a few natural variations (e.g., "add/remove a worktree") are missing, keeping it below the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

It carves out a clear niche (worktree command reference) and actively disambiguates against the sibling skill with "not as the primary user-facing workflow (see nv-worktree-create)", minimizing conflict risk.
