# Phase 1 Plan 01: Provider Settings UI Summary

**Tabbed provider settings UI with Replicate/fal.ai API key management and localStorage persistence**

## Performance

- **Duration:** 12 min
- **Started:** 2026-01-09T12:00:00Z
- **Completed:** 2026-01-09T12:12:00Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments
- Added ProviderType, ProviderConfig, ProviderSettings types for multi-provider support
- Implemented provider settings state in Zustand store with localStorage persistence
- Created tabbed UI in ProjectSetupModal with Project and Providers tabs
- Replicate and fal.ai providers configurable with toggle switches and secure API key inputs

## Task Commits

Each task was committed atomically:

1. **Task 1: Add provider types to types/index.ts** - `acc6b12` (feat)
2. **Task 2: Add provider settings state to workflowStore** - `b6b33bb` (feat)
3. **Task 3: Add Providers tab to ProjectSetupModal** - `0364a8a` (feat)

## Files Created/Modified
- `src/types/index.ts` - Added ProviderType, ProviderConfig, ProviderSettings types
- `src/store/workflowStore.ts` - Added providerSettings state, localStorage helpers, and actions (updateProviderSettings, updateProviderApiKey, toggleProvider)
- `src/components/ProjectSetupModal.tsx` - Added tabbed interface with Providers tab showing Gemini (read-only), Replicate, and fal.ai configuration

## Decisions Made
- Gemini shows as "Default" with env var info (no user input needed)
- Replicate and fal.ai disabled by default, require user to enable and enter API key
- API key inputs use password type with show/hide toggle for security
- Local state pattern used to avoid saving on every keystroke

## Deviations from Plan

None - plan executed exactly as written

## Issues Encountered
- Pre-existing lint configuration issue (`next lint` fails due to missing ESLint config). Not related to this plan's changes; build passes successfully.

## Next Phase Readiness
- Provider types and settings infrastructure ready for Phase 01-02 (Provider abstraction layer)
- API keys accessible from store for future API route implementations
- No blockers for continuing to next plan
