The body is dense and actionable rather than padded: each section leads with executable adb/simpleperf/perfetto commands and limits prose to domain-specific interpretation guidance (e.g. self vs. inclusive samples, profiler limits) that Claude would not reliably know. It is not the level-2 case because there is little generic concept explanation to trim.

Guidance is copy-paste ready throughout — parameterized adb/simpleperf/perfetto/gfxinfo/meminfo/shark-cli commands, a complete heapprofd text-config, and explicit report-generation invocations. It matches the anchor for fully executable, specific examples.

A 5-step Core Workflow is sequenced with explicit validation checkpoints: preflight debuggable/profileable check, discard-on-failure for gfxinfo, wait-for-stable-trace-size before pulling, and fallback paths (use Perfetto/gfxinfo when not debuggable). These feedback loops satisfy the top anchor and avoid the cap for missing validation.

SKILL.md stays an overview plus per-tool commands, while detailed report generation is delegated one level deep to real bundled scripts (scripts/simpleperf_hotspots.sh and scripts/heapprofd_reports.sh, both present), with clearly signaled paths and no nested reference chains.

Lists multiple concrete actions and instruments — "Simpleperf CPU profiles, Perfetto or Compose traces, gfxinfo frame data, dumpsys meminfo snapshots, Java heap dumps, and native allocation traces" — matching the anchor for listing several specific concrete actions.

It answers both what ("Gather and interpret Android performance evidence...") and when ("Use when asked to profile...") with an explicit trigger clause, satisfying the top anchor. It is not capped at 2 because the 'Use when' trigger is present and explicit.

Natural user phrasings are well covered: "profile an Android app flow", "find CPU-heavy functions", "diagnose jank", "compare before/after performance", "explain what code is taking time", mirroring the anchor for good coverage of terms users would actually say.

The niche is sharply scoped to Android performance profiling on an adb target with named tooling, making overlap with unrelated skills unlikely. It is clearly distinguishable and would not trigger for non-performance tasks.
