From wayfinder
Add what-if scenarios (e.g. higher spending, weaker returns, retiring later, a market crash) to an existing Wayfinder plan so they're compared against the baseline across every life-path and Monte Carlo. Use when the user wants to explore alternatives or stress a Wayfinder plan. Requires the Wayfinder MCP server.

A **scenario** is a named override on the baseline's assumptions — `{name, overrides: {param: value}}`. Wayfinder then runs every scenario against every life-path (and Monte Carlo), so the user can see how each what-if changes the odds. Use the Wayfinder MCP tools.

list_plans to get names; confirm which plan. If unsure of its current numbers, get_plan(name).
Each scenario overrides one or more engine params. Common ones (percentages are fractions):
spend_base — total annual spending (e.g. "spend $15k more" → baseline + 15000)essential_spend — the must-cover floornominal_return — market return (e.g. a bear market → 0.04)inflation — e.g. high-inflation regime → 0.05sigma — market volatilitysemi_end_age — work longer / stop earlierend_age — plan to a different age (longevity)new_home — downsize target priceName scenarios for humans: "Higher spend", "Bear market", "Retire at 62", "Live to 100".
Scenarios live as params.scenarios. update_plan merges keys but replaces the scenarios array wholesale, so include every scenario you want kept:
update_plan(name="Jane & John Doe", changes={"scenarios": [
{"name": "Higher spend", "overrides": {"spend_base": 100000}},
{"name": "Bear market", "overrides": {"nominal_return": 0.04}},
{"name": "Work to 70", "overrides": {"semi_end_age": 70}}
]})
To add one, fetch the plan's existing scenarios first (or ask the user) and re-send the full list. To clear them, send {"scenarios": []}.
After saving, run the wayfinder-retirement-advising skill (or at least plan_monte_carlo and compare_lifepaths) so each scenario's money-left and success rate are visible. Call out which what-ifs break the plan (run dry) and which it survives.
