Agent shell loops report installed commands as missing

Source: Troubleshooting reference

Symptom: rg, curl, or stat works initially, then a generated zsh loop prints repeated command not found errors. Assigning status can also fail.

Root cause: zsh’s path array is tied to PATH; assigning a file name to path replaces command search directories. status is a read-only parameter.

Fix: Use variables such as file_path and exit_status. Select Bash explicitly for scripts written for Bash. This is a shell-variable problem, not a reason to reinstall the missing-looking commands.
