Description, as the server wrote it: ```untrusted-server-text DECIDE. Test how robust the decision winner is to changes in CRITERIA WEIGHTS (distinct from sim_sensitivity, which varies scenario inputs). Sweeps each weight +/-variation and reports a robustness score + flip points. ``` ### `evaluate_options_with_scenarios` - The name "evaluate_options_with_scenarios" says "evaluate": a word for a change. Description, as the server wrote it: ```untrusted-server-text COMPOSITE (simulate -> decide). Project each option as its own scenario, then rank the options against weighted criteria drawn from the scenario OUTCOMES. Provide a base 'template', an 'options' array ([{name, inputs}]), and 'criteria' ([{metric, weight, direction}]) where each metric is a scenario key_result. Combines ScenarioSim + DecisionMatrix. ``` ### `health_check` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Aggregated health/status for the whole stack (all three engines + composites).

Description, as the server wrote it: ```untrusted-server-text COMPOSITE (simulate -> compute). Project a scenario, take a per-period cash-flow line from its projections ('cashflow_metric', e.g. 'mrr' or 'net_burn'), and value it exactly: NPV at a discount 'rate', IRR, and undiscounted total. Optional 'initial_investment' becomes the period-0 outflow (needed for IRR). Combines ScenarioSim + PrecisionCalc. ``` ### `sim_break_even` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text SIMULATE. Solve for the scenario input value required to make an output metric hit a target value (deterministic bisection).

Deterministic what-if projection from a template (saas_growth, pricing_change, churn_impact, cost_reduction, hiring_plan, cash_runway, unit_economics, marketing_funnel, compound_growth) or a free-form 'metrics' model. Returns per-period projections, key_results, assumptions_used, methodology, and an explanation. ``` ### `sim_sensitivity` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text SIMULATE. Vary one or more scenario inputs and show the impact on a target output metric (one-at-a-time), with elasticity + most-influential ranking. Requires 'template' and 'variable' (or 'variables'). ``` ### `stress_test_decision` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text COMPOSITE (simulate x decide). Take an options-vs-scenarios decision and stress ONE scenario assumption across a range applied to every option; report how often the baseline winner survives (robustness) and where it flips. Same args as evaluate_options_with_scenarios plus 'stress': {variable, variation, steps}. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `calc_list_metrics` - The name "calc_list_metrics" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text COMPUTE.

Description, as the server wrote it: ```untrusted-server-text SIMULATE. Run 2-3 scenarios and compare their key_results side by side with deltas vs the first (baseline).
