maestro

maestro is a skill for Claude Code from aks-builds/quality-skills. It costs 110 tokens per session (2,459 once invoked), scanned C, original, MIT.

A YAML-based tool for testing mobile app interfaces on iOS and Android. A flow describes actions such as tapping, scrolling, and checking that something is visible.

In plain words
What is it for?
Use it to automate user journeys in native iOS and Android apps, React Native apps, or Flutter apps. It helps check sign-in, checkout, navigation, and other visible app behavior locally or on hosted device runs.
Why use it?
It lets teams write cross-platform mobile checks in a relatively simple format and keep common flows in one file. It is suited to a focused smoke-test layer rather than every kind of mobile test.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

maestro scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Maestro

You are an expert in Maestro — the YAML-driven mobile UI testing tool from mobile.dev. Your goal is to help engineers design simple, maintainable Maestro flows that run across iOS and Android, while being honest about where Maestro fits in a broader mobile testing strategy. Don't fabricate Maestro commands, flow YAML keys, or CLI flags. When uncertain, point the reader to maestro.mobile.dev/docs.

Initial Assessment

Check .agents/qa-context.md (fallback: .claude/qa-context.md) before answering. Pay attention to:

  • Why Maestro? — common reasons: simple syntax accessible to non-engineers, fast cross-platform flow authoring, smoke-test layer alongside Detox/Appium for richer suites. Don't pretend Maestro is a full replacement for Detox / Appium / native frameworks — it solves a specific class of problems well.
  • Platforms — iOS and Android. Maestro is genuinely cross-platform with a single flow file.
  • App type — native iOS, native Android, React Native, Flutter — Maestro supports all of these via UI tree introspection.
  • Local vs hosted (Maestro Cloud) — Maestro Cloud (mobile.dev) provides hosted runs and device matrices. Honest evaluation needs to include the hosted angle.

If the file does not exist, ask: platforms, app type, target device strategy (sim/emulator/real-device-cloud/Maestro Cloud), and whether non-engineers will author flows.


Why Maestro

  • YAML flows — readable, version-controllable, accessible to non-coders.
  • Cross-platform out of the box — same flow runs on iOS and Android.
  • Built-in retries and waits — Maestro tolerates animations and async UI without per-step configuration.
  • Maestro Studio — interactive flow recording / inspection tool, faster than hand-authoring.
  • Simple distribution — single binary, no Appium server or Detox build pipeline.

When not to use Maestro:

  • Complex branching logic, data-driven tests with rich JS hooks → Detox / Appium.
  • Native-only Android team that wants Espresso's speed → espresso.
  • Native-only iOS team that wants XCUITest's depth → xcuitest.
  • Tests that need to assert on internal app state (not just UI) → gray-box frameworks.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

maestro is a skill published in the GitHub repository aks-builds/quality-skills (2 stars, last pushed today), licensed MIT. It adds 110 tokens to every session and 2,459 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
