Julia Reset

Kill the Julia worker process and spawn a fresh one (hard reset).

What This Does

This is a hard reset that:

• Kills the worker process entirely
• Spawns a fresh Julia worker
• Clears all variables, functions, and loaded packages
• Enables type/struct redefinitions (necessary in Julia < 1.12)
• Re-activates the previously activated project
• Reloads Revise.jl if available

Instructions

1. If the user provides a session name argument, pass it as the session parameter
2. Call the reset MCP tool
3. Report the old and new worker IDs to the user
4. Remind the user that packages need to be reloaded with using

When to Use

• You need to redefine a struct layout (Julia < 1.12)
• The session is in a bad/corrupted state
• You want a completely clean slate
• Code is stuck/hanging (infinite loop, long computation)

When NOT to Use

• For function/method changes: use revise(action="revise") instead — it preserves session state
• For package issues: try pkg(action="resolve") first
