Lists specific concrete actions: 'Creates or removes a git worktree using the project scripts and shared config.' This clearly describes two distinct operations (create and remove) with the method (project scripts and shared config).

Clearly answers both 'what' (creates or removes a git worktree using project scripts and shared config) and 'when' (explicit 'Use when...' clause listing multiple trigger scenarios).

Excellent coverage of natural trigger terms: 'create a worktree', 'add a worktree', 'remove a worktree', 'delete a worktree', 'parallel branch', 'separate directory'. These are natural phrases users would actually say.

Git worktree management is a very specific niche. The triggers are distinct and unlikely to conflict with general git skills or other file management skills. Terms like 'worktree' and 'parallel branch in a separate directory' are highly specific.

The content is lean and efficient. It doesn't explain what worktrees are or how git works—it assumes Claude knows. Every line provides actionable guidance: commands, flags, and constraints. The reminder about post-setup steps is necessary project-specific knowledge.

Provides specific, copy-paste-ready commands for both create and remove operations, with clear flag variations (--from, --cd). Covers both user-provided and missing arguments. The constraint against raw `git worktree add` is a concrete, actionable boundary.

The create workflow has a clear sequence (run script → remind about setup), but there's no explicit validation checkpoint after creation or after the post-setup steps. For an operation that sets up a parallel working directory with submodules and config, a verification step (e.g., confirm the worktree appears in `git worktree list`) would strengthen the workflow.

The skill is appropriately concise as an overview, with a clear one-level-deep reference to the full worktree documentation. The content is well-organized into create/remove sections with a reference section, which is ideal for this scope.
