Conciseness

The body is ~14 lines of pure routing: 'Map what an attacker observes or controls, the required capability, the trust boundary crossed, and where defenders have evidence or authority' plus annotated links. No padding, no explaining concepts Claude already knows; every token earns its place.

Actionability

Concrete routing guidance: each link is annotated with explicit topics ('for overlays, access paths, driver communication, world-to-screen, and input') and a deferral rule ('Use the narrower engine, graphics, DMA, kernel, mobile, server, or supply-chain skill when one boundary dominates'). Minor gap: no inline worked example of the four-part mapping output, so guidance is mostly but not fully concrete for an instruction-only skill.

Workflow Clarity

The single task is unambiguous (topic → reference → defensive mapping) and the deferral instruction covers boundary selection, but the sequence for combining multiple references when a question spans several files is left implicit — a minor checkpoint gap rather than a missing workflow.

Progressive Disclosure

Verified against the actual bundle: all 7 referenced files exist in references/, each link is one level deep and clearly signaled with a topical annotation, and the split is appropriate (SKILL.md is a lean index; detail lives in the references). Cross-links inside references point laterally to sibling skills rather than nesting content a second level.

Specificity

'Classify game-cheat capabilities and their defensive implications' names the domain and the concrete action, and the scope enumeration ('memory, injection, rendering, input, engines, kernels, DMA, and remote transports') is broad coverage with only minor gaps. Not a 5 because there is essentially one action verb rather than several distinct concrete actions.

Completeness

Both parts are present: the 'what' is clear (classify capabilities and defensive implications) and an explicit 'Use for authorized threat modeling, not operational deployment' clause answers 'when'. Not a 5 because the trigger is a purpose statement with a negative scope rather than concrete trigger phrases ('when the user mentions...') as in the 5 anchor.

Trigger Term Quality

Good keyword coverage: 'game-cheat', 'memory', 'injection', 'rendering', 'input', 'engines', 'kernels', 'DMA', 'remote transports', 'threat modeling'. A few natural terms users would actually say are missing — 'anti-cheat', 'game hacking', 'cheat detection', or concrete cheat names like aimbot/wallhack — so it sits between the 4 and 5 anchors, noticeably above the midpoint.

Distinctiveness Conflict Risk

A clear niche (game-cheat capability classification for defense) with distinctive vocabulary, but there is minor overlap risk with closely related sibling skills the body itself names (engine, graphics, DMA, kernel, anti-cheat), so it is 'mostly distinct' per the 4 anchor rather than fully conflict-free.
