The user wants to run a probe — make one minimal viable change by hand and verify it works, then write the recipe into a task book afterward.
Create the one-time bypass flag:
node "${CLAUDE_PLUGIN_ROOT}/bin/pi-probe"
Then tell the user: this flag is good for one use only — it turns itself off automatically after the next Write/Edit goes through. Once the probe is done, immediately write the verified recipe into a task book, and dispatch everything else to pi as usual.
