What problem does it solve?

It helps you write correct, reliable SQL queries against Perfetto trace data so you can analyze performance and profiling signals without brittle query logic or unsafe assumptions.

Core Features & Use Cases

• PerfettoSQL query guardrails: Enforces idempotent object creation rules (CREATE OR REPLACE, safe drops for virtual tables) to prevent re-run failures.
• Correct time and interval handling: Provides guidance for incomplete slices (dur = -1) and safe overlap logic using standards/library features (including SPAN_JOIN/intervals.overlap precedence).
• Trace-specific correctness: Advises correct join keys (utid/upid), safe argument extraction (EXTRACT_ARG), and safe string matching (GLOB instead of LIKE) for performance and accuracy.
• Execution protocol: Runs queries via the trace_processor wrapper with --query-string and validates schema/module usage against the Perfetto Standard Library docs.

Quick Start

Ask the agent to generate and execute a validated trace_processor SQL query for your specific Perfetto performance question, using the Perfetto Standard Library schemas for every referenced table or view.
