 "title": "Find which code writes a field that goes wrong",
 "page_title": "How to find which code writes a field that goes wrong with Debroid",
 "summary": "Watch a field for access and modification, then read the stack at each change.",
 "who": "A developer or agent tracking a field whose value changes unexpectedly during a user flow.",
 "problem": "Searching the codebase for every write to a field is slow, and the actual writer often depends on runtime order.",
 "outcome": "The agent gets a list of the code locations that touched the field during the flow, with stack traces, and can name the writer.",
 "steps": [
  "Install the CLI with `curl -fsSL https://raw.githubusercontent.com/PatilShreyas/debroid/main/install.sh | bash`",
  "Set a field watchpoint with `debroid watch` (access and modify are both on by default)",
  "Run the user flow in the app, then collect events with `debroid poll --with-stacktrace` (inferred, check the README)",
  "Check the active points with `debroid points`",
  "Remove the watchpoint with `debroid remove-watch` when finished"
 ],
 "agent_prompt": "Use the Debroid CLI to watch the field <field-name> in <class-name> of the app <package-name>. Run <user-flow> and then run `debroid poll --with-stacktrace`. Return each access or modification with its stack trace as JSON, and verify that the watched field name matches the one you set with `debroid points`.",
 "agents": [
  "claude-code",
  "codex",
  "cursor"
 ],
 "difficulty": "Advanced",
 "time": "60 minutes",
 "basis": "readme",
 "caveat": "The README does not say how the watch command identifies a field beyond its signature, so confirm the field is picked up with `debroid points` before relying on the results.",
