 "title": "Compare two builds of a binary by function changes",
 "page_title": "How to compare two builds of a binary by function changes with Eleven",
 "summary": "Diff two versions of a program function by function and read the changes like a code review.",
 "who": "A security reviewer or release engineer who needs to see what changed between two builds of the same program.",
 "problem": "Comparing two binaries byte by byte shows little, so it is hard to tell which behavior actually changed.",
 "outcome": "A function-level list of changes between the two builds that you can read like a code review, with an agent summary of what matters.",
 "steps": [
  "Open the first build in Eleven and create a project for it.",
  "Open the second build in Eleven as a separate project or in the same project, following the diffing workflow in the app.",
  "Run the diff view to see the functions that changed.",
  "Ask your agent to summarize the most important changes and the functions they affect.",
  "Save the project with ⌘S if you want to share the comparison as a `.eleven` file."
 ],
 "agent_prompt": "Using the Zfinix/eleven app, diff the builds at <path-to-old-build> and <path-to-new-build>, then ask the agent to list the five most important changed functions with a one-line reason each. Verify that each function name exists in both builds.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "The README describes diffing by function but does not give the exact menu steps, so check the app for how to start a diff.",

 "lang": "typescript",
 "requirements": [
  "A supported OS: macOS 14 or later on Apple Silicon, Windows x64, or Linux x64",
  "An ACP-compatible agent (Eleven installs ACP adapters when they are needed)",
  "Rizin for fast opening, or Ghidra 12.x with Java 21 for the clearest pseudocode",
  "jadx if you plan to open Android APK files",
  "A binary, APK, GPU kernel, shader or model file you have the right to analyze"
