# Read and explain formulas as an agent

Use `list_formulas` when a user asks how a property is calculated, asks why values differ by segment or period, or wants to review existing formulas.

## Workflow

1. Resolve the property name with search.
2. Choose the scenario from runtime context or the user's request.
3. Call `list_formulas` with the target property ID.
4. Pass an empty conditions array to read all formulas, or exact conditions when checking one scope.
5. Explain the expression, scope, Formula period, and likely precedence in business language.

## Formula cards

`list_formulas` renders each result as a formula card. Do not repeat the cards as a table, bullet list, or per-formula prose.

After the tool result, text should contain only:

* A one-sentence headline
* Any assumptions or educated guesses
* A clarifying question when needed

## Historical reads

Use `as_of_point` only when the user asks for formula state at a prior change-log point. Omit it for current state.

## Generated formulas

Results can include default generated formulas for source-backed properties. Treat them as effective formulas when explaining current behavior.
