 "title": "Check what an app window shows after each step",
 "page_title": "How to check what an app window shows after each step with macOS Harness",
 "summary": "Read a window, act once, then read again to see only what changed.",
 "who": "A QA tester or support engineer who needs to confirm how a Mac app responds to a sequence of actions.",
 "problem": "Checking each step of a Mac app workflow by hand is slow and easy to skip.",
 "outcome": "A short log of each action and the changed window text after it, so the tester can see what the app did.",
 "steps": [
  "Install macOS Harness with uv using Python 3.12, then run `macos-harness install --agent codex` or your agent's name. (inferred, check the README)",
  "Run `macos-harness get_app_state --app \"TextEdit\"` to record the starting window.",
  "Run `macos-harness press_key --app \"TextEdit\" --key \"super+s\"` to trigger the action under test.",
  "Run `macos-harness get_app_state --app \"TextEdit\"` again and compare it with the starting read.",
  "Run `macos-harness telemetry disable` if you do not want anonymous telemetry on this machine."
 ],
 "agent_prompt": "Using the macos-harness repo at https://github.com/browser-use/macos-harness, read <app name> with `macos-harness get_app_state`, perform the action in <test steps>, and read the window again. Verify and report only the lines that changed between the two reads, and state whether the expected change appeared.",

 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",

 "lang": "python",
 "requirements": [
  "A Mac running macOS, since the project is macOS only",
  "Python 3.12 and uv, to install macOS Harness",
  "Accessibility and Screen Recording permissions, which every call needs",
  "A coding agent CLI such as Claude Code or Codex to run the commands"
