The body is largely lean and assumes Claude's competence, but it embeds time-sensitive version numbers in the main flow — 'com.unity.test-framework.performance': '3.0.3' and the @3.0 / @1.2 URL segments — which the rubric penalizes unless they sit in a deprecated/version-notes section; this is 'mostly efficient but could be tightened', not the verbose score-1 case.

Fully executable, copy-paste-ready guidance: complete C# Measure.Method / Measure.Frames / GC.Alloc blocks, the 'unity -batchmode -runTests ...' CI command, stat-command and ProfileGPU tables, and a concrete budget-report template.

A clearly sequenced 7-step process (Unity capture → analyze → automated tests; Unreal stat triage → Insights; GPU budgets; CI gate) with explicit validation checkpoints — 'fail the build if any PerformanceMeasurement sample set has a median or p99 exceeding the declared threshold' and 'A FAIL on p99 triggers a regression investigation'.

A concise spine with an Overview, seven steps, template, anti-patterns, and limitations, deferring module detail to two clearly signaled, one-level-deep references (references/unity-profiler.md, references/unreal-insights.md) that contain real content rather than further redirects and explicitly note 'Cited once here rather than repeated in the spine'.

Lists multiple concrete actions with specifics — 'Profiles game builds against frame-time, memory, GPU draw-call, and GC-spike budgets', 'Establishes pass/fail thresholds (16.6 ms at 60 fps, 33.3 ms at 30 fps)', 'writes automated performance regression tests that run in CI', 'emits a structured budget report per SKU' — exceeding the multi-action anchor.

Clearly answers both 'what' (profiles, establishes thresholds, writes CI tests, emits report) and 'when' via an explicit 'Use when...' trigger clause, so it is not capped at 2 for a missing trigger.

The 'Use when a title must hit a declared frame-time or memory budget before a milestone gate or platform-cert submission, or when a recent change needs a performance regression check' clause uses natural domain terms a game-dev/QA user would actually say (frame-time budget, milestone gate, platform-cert submission, regression check).

A clear, narrow niche — game performance budget profiling tied to milestone gates / platform-cert submission — with distinct triggers unlikely to collide with other skills.
