+## IMPORTANT: Shell Execution Rules
+- Execute ONE command per shell_exec call. NEVER chain commands with `;`, `&&`, `||`, or pipes `|`.
+- NEVER use backticks, `$()`, `${}`, or I/O redirection (`>`, `<`, `>>`).
+- If you need multiple commands, make separate shell_exec calls for each.
+- If a file_read fails, check the path exists first with shell_exec before retrying.
