From the author

Records and analyzes Android performance data and diagnoses performance bottlenecks across user apps, system apps, and system services, even if the user does not explicitly mention profiling or traces. Use when: recording system traces, CPU call stacks, Vulkan GPU/DRM memory, or Java/native heap profiles; analyzing Perfetto traces for UI jank, frame drops, ANRs, or app startup latency issues; investigating CPU bottlenecks, IPC/Binder storms, or thread scheduling stalls; diagnosing battery drain, modem power rails, and kernel wake locks; debugging memory pressure, Low Memory Kills (LMK), OOMs, leaks, and allocation churn; performing A/B baseline trace comparisons to find regressions; executing ad hoc PerfettoSQL queries on Android traces.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The android-profiler skill provides a structured approach to capturing and interpreting Android performance data. It acts as an orchestrator for recording system traces, heap dumps, and CPU profiles, and provides workflows for deep-dive analysis using Perfetto. The skill is designed to help developers identify the root causes of UI jank, memory leaks, battery drain, and system-level performance regressions by leveraging standardized trace analysis and SQL-based querying.

What it does

  • Records system traces, CPU call stacks, and memory heap profiles.
  • Analyzes Perfetto traces to identify UI jank, frame drops, and startup latency.
  • Investigates system-level issues like IPC Binder storms and thread scheduling stalls.
  • Diagnoses power-related issues including battery drain and kernel wake locks.
  • Debugs memory pressure, LMK events, and native or Java heap leaks.
  • Executes custom PerfettoSQL queries for advanced trace data exploration.

When to use it

  • When you need to investigate app startup latency or intermittent UI jank.
  • When diagnosing memory-related crashes like OOMs or excessive allocation churn.
  • When analyzing system-wide performance regressions using A/B trace comparisons.
  • When you need to profile power consumption or modem power rail activity.
  • When you need to perform ad hoc analysis on complex Android system traces.

Advantages

  • Provides a unified workflow for both recording and analyzing performance data.
  • Reduces ambiguity by enforcing clear intent disambiguation before execution.
  • Includes specialized reference hints for CPU, memory, graphics, and power analysis.
  • Supports advanced data exploration via PerfettoSQL integration.
  • Ensures consistent environment setup through standardized path management.

Usage examples

“My app is stuttering during scrolling. Can you help me find the cause?”
The agent will initiate a trace recording session focused on UI jank, then guide you through analyzing the resulting Perfetto trace for frame drops and thread stalls.
“I suspect a memory leak in my application. How can I investigate?”
The agent will help you capture a Java or native heap dump and provide steps to analyze the memory allocation patterns to identify potential leaks.

Documentation by Google LLC

Your primary role is to figure out what the user wants to do (disambiguation), find the right instructions for it (workflow discovery), and follow them step-by-step (following the execution plan). If the request is unclear, work with the user to finalize the execution plan before proceeding.

Prerequisites and Setup

Before executing any workflows, read references/env_setup.md. It defines what to set $SKILL_ROOT to - the anchor every other path in this skill is written against.

Intent Disambiguation

Do not guess the user's intent. If the user request is not clear, ask the user what they want to do before proceeding.

Recording

Route all recording requests through recording/recording_orchestrator. This defines guidelines and pre-flight checks or dependency checks that apply to all recording workflows, and ensures you have the necessary setup to proceed. Read the orchestrator and execute the plan it describes based on what the user wants to record (for example, a system trace or a heap dump).

Analysis

Route all analysis requests through analysis/analysis_orchestrator.

Requirements and compatibility

Works with: Claude Code, Claude apps, OpenAI Codex, GitHub Copilot, Cursor, Gemini CLI, Kiro, OpenCode, Goose, Amp, Roo Code, JetBrains Junie, Factory Droid, Devin (ex-Windsurf), Mistral Vibe, OpenHands, Letta

“Works with” means the tool reads the open Agent Skills format; a skill written for one tool may use features others lack.
