Conciseness

The body is efficient and largely assumes Claude's competence — it gives engine-specific commands, API specifics, and version numbers rather than explaining what a profiler or GC is — but a few prose passages (e.g., 'stat unit is the first command to run on any new build...') and some anti-pattern rows could be trimmed, placing it at the 4 anchor ('efficient; minor instances of over-explanation') rather than the 5 anchor where every token earns its place.

Actionability

Provides copy-paste-ready, executable guidance for the common cases: Measure.Method/Measure.Frames C# samples, a GC.Alloc ProfilerMarkers snippet, the exact CI batch command, a stat-commands table, and `ProfileGPU`/`stat unit` commands, matching the score-5 anchor for fully executable coverage rather than the 4 anchor with minor gaps.

Workflow Clarity

Seven clearly sequenced Steps with explicit validation gates ('fail the build if any PerformanceMeasurement sample set has a median or p99 exceeding the declared threshold', 'A FAIL on p99 triggers a regression investigation') and an anti-patterns checklist, but the validate→fix→retry feedback loop is only implicit, matching the 4 anchor ('most checkpoints present; minor validation gaps') rather than the 5 anchor's explicit error-recovery loops.

Progressive Disclosure

The spine is an overview that points module and trace-channel detail to two well-signaled, one-level-deep references (references/unity-profiler.md and references/unreal-insights.md), both confirmed real leaf files with no nested references, matching the score-5 anchor for clear overview with appropriately split one-level-deep navigation.

Specificity

Lists multiple concrete actions across two engine stacks — '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' — which is comprehensive coverage, matching the score-5 anchor rather than the 4 anchor that implies minor gaps.

Completeness

Explicitly answers what ('Profiles game builds... emits a structured budget report per SKU') and when ('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'), directly matching the score-5 anchor with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage including synonyms ('frame-time'/'60 fps'/'30 fps', 'performance regression'/'CI regression') and tool names users would say ('Unity Profiler', 'Unreal Insights', 'stat commands', 'budget', 'platform-cert'), matching the score-5 anchor for synonyms and variations rather than the 4 anchor with a few missing.

Distinctiveness Conflict Risk

Occupies a clear niche (game-engine performance QA against declared budgets with platform-cert gating) with distinct triggers unlikely to fire for unrelated skills, matching the score-5 'clear niche with minimal conflict risk' anchor rather than the 4 anchor's minor overlap.
