## TL;DR

Two formulas reference each other in a circle. Break the cycle: inline one formula's logic or move the shared logic to a trigger.

## Error

```text
CIRCULAR_DEPENDENCY: circular dependency
```

## Steps

1. Trace the formula references to find the cycle Expected: you see A references B references A.
2. Inline one side's logic or move it to a trigger/workflow Expected: the cycle breaks.
3. Save the formulas Expected: they compile.
4. Document the dependency direction Expected: the next editor does not reintroduce it.

## When to use

- CIRCULAR_DEPENDENCY on formula save
- Two formulas reference each other

## When not to use

- Only one formula (then it references itself)
- The cycle spans objects (then trace cross-object references)

## Tool compatibility

- Salesforce formula dependencies
- Formula fields

## Variant phrasings

### circular dependency formula

Two formulas reference each other. Break the cycle.

### CIRCULAR_DEPENDENCY

Same: inline one side or move logic to a trigger.

## Why it happens

Agents generate formulas per field without tracking the reference graph, and the cycle only appears at save time.

## Edge cases

- Validation rules and rollups can join the cycle too
- Compile size limits can also bite once the cycle is broken
