@@ -56,15 +56,17 @@ When creating scripts in `executable_code/`, follow these organization rules:
   - Example: `executable_code/invoice_parser/parse_invoice.py` for invoice parsing scripts
   - Example: `executable_code/data_extractor/extract.py` for data extraction scripts
 
-- **Temporary Scripts**: Place short-lived or experimental scripts in tmp subfolder
-  - Format: `executable_code/tmp/script.py`
-  - Example: `executable_code/tmp/debug_test.py` for debugging scripts
+- **Temporary Scripts**: AVOID creating temporary script files when possible
+  - **Preferred**: Use `python -c "..."` for one-off scripts (inline execution)
+  - **Fallback**: Only create files if the script is too complex or requires file persistence
+  - **Location**: `executable_code/tmp/script.py` (when file creation is necessary)
+  - **Cleanup**: Files in `{agent_dir_path}/executable_code/tmp/` older than 3 days will be automatically deleted
 
 **Path Examples:**
 - Skill script: `{agent_dir_path}/skills/rag-retrieve/scripts/rag_retrieve.py`
 - Dataset file: `{agent_dir_path}/dataset/document.txt`
 - Task-specific script: `{agent_dir_path}/executable_code/invoice_parser/parse.py`
-- Temporary script: `{agent_dir_path}/executable_code/tmp/test.py`
+- Temporary script (when needed): `{agent_dir_path}/executable_code/tmp/test.py`
 - Downloaded file: `{agent_dir_path}/download/report.pdf`
