Conciseness

The body is largely lean and command-focused with clear section headers. Minor trimmable redundancy remains: the intro ("Zero dead time. While one session runs tests...") repeats the Trigger section, the Workflow section restates the Commands section, and "Both approaches create an isolated working copy..." explains a concept Claude already knows — matching anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Commands are copy-paste ready and cover the common cases: `claude --worktree`, `git worktree add ../project-feat feature-branch`, `git worktree list`, `git worktree remove`, `git worktree prune`, and a pre-cleanup status check. This matches the fully-executable top anchor.

Workflow Clarity

A clear 4-step sequence (list → create → open session → cleanup) with an explicit validation checkpoint before the destructive removal op ("Before removing a worktree, verify changes are committed: `git -C ../project-feat status`"), so the destructive-operation cap does not apply. It falls short of anchor 5 only because there is no error-recovery guidance if the verification fails (e.g., uncommitted changes found).

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and none are needed: the ~85-line body is well-sectioned with nothing that belongs in a separate file. Per the simple-skill scoring note, well-organized sections with no external-reference need warrant the top score.

Specificity

"Create and manage git worktrees" names the domain and two actions, but "manage" is generic and no further concrete operations (add, remove, prune, list) appear. This matches the anchor for 1-2 concrete actions without comprehensive coverage, below anchor 4 which expects several specific actions.

Completeness

The description explicitly answers both "what" (create and manage git worktrees for parallel coding sessions) and "when" (blocked on tests, builds, multiple branches, context switching, exploring approaches) with concrete trigger phrases. This clearly matches the top anchor; the when-clause is specific, not merely present.

Trigger Term Quality

Phrases like "blocked on tests, builds", "multiple branches", "context switching", and "exploring multiple approaches" are natural things users would say. A few common synonyms (e.g., "parallel", "work on two branches at once") are missing, keeping it below the comprehensive anchor 5.

Distinctiveness Conflict Risk

Git worktrees is a clear, distinct niche with specific triggers, but broad phrases like "context switching" and "blocked on tests" could also plausibly match general workflow-optimization or background-task skills. Minor overlap risk, matching anchor 4 rather than the minimal-conflict anchor 5.
