perfetto-trace-analysis

or jank issues in Android apps. Use when the user provides a Perfetto trace file and asks any question, ongoing investigation, or open-ended request to analyze its contents.

Resources

• Domain Hints: Reference files for specific performance areas are located in references/hints_[domain].md (e.g., hints_cpu.md, hints_io.md). To avoid context bloat, do not load all hints at once; read the specific file only when you have narrowed your investigation to that domain.
• Perfetto SQL Skill: This workspace may contain a perfetto-sql skill that guides translating intents into valid queries. You must search for and locate it, then follow its Execution Protocol for all SQL generation. If it is not present, proceed as without it, downloading the trace processor and creating + running the queries to the best of your abilities.
