Lists multiple specific concrete actions: explains core vocabulary, Read vs Write tool boundary, change-description + -o mutations conventions, gate semantics, Delete Gates and Destroy Gates, and routing to dedicated skills. Very detailed about what it covers.

Clearly answers both 'what' (explains core vocabulary, gate semantics, routes to dedicated skills) and 'when' (explicit 'load when' clause with multiple trigger scenarios, plus a 'Do not load when' clause with concrete counter-examples for disambiguation).

Excellent coverage of natural trigger phrases users would say: 'what is a Unit / Space / Target / Worker / Trigger / Filter / Link', 'how do I do X in ConfigHub', 'protect this Space from accidental deletion', 'why can't I delete this?', 'how do I lock down critical infra?', 'add a delete gate'. These are realistic user utterances.

Exceptionally distinctive — explicitly defines its niche as an orientation/routing skill and includes 'Do not load when' examples that name specific other skills (triggers-and-applygates, cub-mutate, cub-query), making conflict boundaries very clear.

The skill is reasonably efficient for an orientation/routing skill covering many entities, but some entity descriptions could be tighter (e.g., the Target and Worker definitions include parenthetical lists that add bulk). The Delete/Destroy Gates section is thorough but somewhat lengthy for an orientation skill — it reads more like a dedicated skill than a routing overview.

The gates section provides fully executable, copy-paste-ready CLI commands for adding and removing gates across multiple entity types. The routing table gives concrete skill names. The operational invariants give specific, actionable conventions (--change-desc, -o mutations). Even though this is primarily an orientation skill, the concrete guidance is excellent where it matters.

The 'loop' section provides a clear 4-step sequence for the orientation use case. The gates workflow (add → name → remove with sentinel syntax → then delete) is clearly sequenced with the explicit constraint that all gates must be removed before proceeding. Stop conditions and tool boundaries are explicit. For a read-only routing skill, this is well-structured.

References to external files (references/cub-cli.md, references/functions-catalog.md, etc.) are clearly listed, and the routing table effectively points to dedicated skills. However, no bundle files were provided to verify these references exist, and the Delete Gates section is quite substantial inline content that could arguably be its own referenced file rather than embedded in an orientation skill. The balance between overview and inline detail is slightly off.
