AI agent investigated 211 stray deletion-log entries — the bug was in its own code

Input-X · reddit · 2026-09-13

In the open-source multi-agent framework AIPass, the router agent "drone" found 211 entries that shouldn't exist in a deletion log. Its 156 delete-related tests produced byte-identical logs — the culprit was another agent's test writing to the wrong project's log, because drone picked the log by current working directory instead of the project where the file was deleted. The bug persisted 3 weeks (Aug 14–Sep 6). Developer Patrick ruled to annotate, not delete: "a ledger nobody edits keeps the property that makes it worth having." The post also details AIPass's architecture: named Claude Code instances with memory files and mailboxes, drone as a single inspectable doorway, and git-write interception.
