spectacular

Use when reviewing a Spectacular pull request, branch diff, or set of staged/working changes for quality — reuse, simplification, efficiency, and altitude cleanups, plus adherence to the project guidelines. Review-only it surfaces findings and never commits the changes it proposes.

Use when creating, preparing, listing, switching between, or removing git worktrees for the Spectacular package, especially when multiple agents work in parallel. Covers safe multi-agent branch isolation, the sibling worktree layout, Testbench dependency setup, the required verification gate, and cleanup.
