What problem does it solve?

This Skill helps you identify the root cause of performance issues (CPU, graphics, I/O, IPC, memory, and power problems) inside an Android Perfetto trace by building a verified chain of evidence rather than relying on guesses.

Core Features & Use Cases

• Evidence-based investigation workflow: Creates a per-trace scratchpad to record verified facts only, then iteratively forms hypotheses, collects data, and drills down with strict evidentiary rigor.
• Domain-hints-driven profiling: Uses expert-vetted techniques across CPU scheduling, graphics rendering/memory, I/O stalls, binder/IPC patterns, memory pressure, and battery-related rails/wakelocks.
• Perfetto SQL generation with guardrails: Follows the provided SQL execution protocol, including correct handling of incomplete slice durations (dur = -1), safe joins via UTID/UPID, and mandatory use of GLOB for matching.
• Broad-to-narrow trace strategy: Starts with high-level metrics, then narrows with targeted queries; includes startup/package discovery when the request is broad.

Quick Start

Use the perfetto-trace-analysis skill to analyze the attached Perfetto trace and produce a verified root-cause report for the slow performance you observe.
