# useAccountabilityPrefill

# useAccountabilityPrefill

**Source:** `hooks/useAccountabilityPrefill.ts` (56 lines)

The useAccountabilityPrefill hook auto-populates penalty and waiver fields on the task draft from the user's saved accountability preset, providing a zero-friction commitment creation experience.

***

## Flow

1. On mount, checks if the user has a saved accountability preset in Convex
2. If a preset exists AND the draft's isAccountabilityPrefilled flag is false:
   * Copies the preset's penalty config into the draft's penalty field
   * Copies the preset's waiver config into the draft's penalty\_waiver field
   * Sets isAccountabilityPrefilled to true
3. If no preset exists, does nothing (user configures manually)

***

## Guard Flag

The isAccountabilityPrefilled flag on the draft store prevents re-population on re-renders. Without this guard, navigating between spoke screens would overwrite any manual penalty changes the user made since the initial prefill.

```typescript theme={null}
if (!draft.isAccountabilityPrefilled && savedPreset) {
  setDraftPenalty(savedPreset.penalty);
  setDraftWaiver(savedPreset.waiver);
  setIsAccountabilityPrefilled(true);
}
```

## Where It Runs

This hook is called inside the (create-commit)/\_layout.tsx alongside usePresetHydration. It runs at the layout level so the prefill occurs before any spoke screen mounts, ensuring the Hub screen immediately shows the pre-populated penalty summary.
