 "title": "Flag AI provenance marks in files Claude Code writes",
 "page_title": "How to flag AI provenance marks in files Claude Code writes with Watermarks Remover",
 "summary": "Get a PostToolUse hook that checks each file your agent writes for AI provenance marks.",
 "who": "A developer using Claude Code who wants every file the agent writes checked before it reaches git.",
 "problem": "Agent-written files can carry provenance marks, and a skill alone depends on the model choosing to run it.",
 "outcome": "Each file the agent writes is scanned by a harness-run hook in check mode, and any findings are reported to the model.",
 "steps": [
  "From the repository checkout, run `python3 install_skill.py --skill remove-ai-marks --target claude-code`.",
  "Start the service with `make serve`.",
  "Install the plugin in Claude Code with `/plugin marketplace add guillaumemeyer/watermarks-remover` and then `/plugin install watermarks-remover@watermarks-remover`.",
  "Confirm Hook mode is set to check in `/plugin manage`, or add the PostToolUse hook from the README to ~/.claude/settings.json with --mode check.",
  "Ask the agent to write a test file, then confirm the hook reports findings without changing the file."
 ],
 "agent_prompt": "In the watermarks-remover repo, use the remove-ai-marks skill in Claude Code to write <file path> with <test content>. Report whether the PostToolUse hook in check mode flagged any provenance marks, and leave the file unchanged unless I ask you to clean it.",
 "agents": [
  "claude-code"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The hook covers files the agent writes, not the chat messages themselves, which the README says no hook can rewrite.",
