My agents wrote ~4,000 markdown files in a year. I never opened most of them.
A user counted 3,950 markdown files created by agents in one year — plans, summaries, handoff notes — and found 89% were never opened within a week. The thread is a warning about agent-generated documentation debt: agents writing for themselves instead of for the reader. Suggested fixes include mandatory why-this-exists headers and automatic archival of unreferenced files.
