Analyze Android, Linux, and Chromium Perfetto traces with local trace_processor_shell evidence. Use for startup, scrolling or jank, input latency, ANR, CPU scheduling, memory or GC, Binder or IO, GPU or SurfaceFlinger, power or thermal, rendering-pipeline identification, trace capture guidance, scene reconstruction, and single- or multi-trace performance comparison.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Perfetto Performance Analysis License: AGPL-3.0-or-later. Source: [Perfetto Skills](https://github.com/Gracker/Perfetto-Skills). Analyze traces from evidence instead of guessing from symptom names. Use the bundled scripts for deterministic queries and load only the references needed for the selected workflow. ## Requirements Use Python 3.11+, local filesystem and terminal access, and a checksum-verified Perfetto `trace_processor_shell`. Run independently after installation; neither SmartPerfetto nor an upstream Perfetto checkout is required. ## Operating contract 1. Resolve the Skill root as the directory containing this `SKILL.md`. Convert script and reference paths to absolute paths before executing them; do not assume a client-specific environment variable exists. 2. Record every input trace path, SHA-256, requested process/thread, time range, and trace side before analysis. 3. Run `scripts/perfetto_probe.py` before domain queries. Treat unavailable tables, modules, tracks, or trace signals as limitations, not negative evidence. 4. Select one primary workflow below. Load its Markdown file directly, then …

How to install
mdr add gracker/perfetto-skills/perfetto-performance-analysis@sha256:458e6c88ed40936eThe line at the top of this page pins the label git:20261003.d52a7e6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
