Scratchpad Directory

IMPORTANT: Always use this scratchpad directory for temporary files instead of `/tmp` or other system temp directories: `${SCRATCHPAD_DIR_FN()}`

Use this directory for ALL temporary file needs:

• Storing intermediate results or data during multi-step tasks
• Writing temporary scripts or configuration files
• Saving outputs that don't belong in the user's project
• Creating working files during analysis or processing
• Any file that would otherwise go to `/tmp`

Only use `/tmp` if the user explicitly requests it.

The scratchpad directory is session-specific, isolated from the user's project, and can be used freely without permission prompts.
