# Dependency graph
requires:
  - phase: 38-telegram-bridge
    provides: POST /api/telegram/token endpoint for token validation
  - phase: 37-voice-pipeline
    provides: multi-step onboarding wizard with VoiceStep at step 4
provides:
  - TelegramStep.tsx onboarding component with BotFather guided setup and token validation
  - Updated NexusOnboardingWizard with 7-step flow (Telegram inserted at step 5)
affects:
  - future onboarding changes must account for 7-step flow
  - 38-04 if it exists (downstream telegram wiring)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Onboarding step components receive onNext/onBack props
    - Token validation via POST before enabling Continue button
    - Step is always skippable (Skip calls onNext without saving)

key-files:
  created:
    - ui/src/components/onboarding/TelegramStep.tsx
  modified:
    - ui/src/components/NexusOnboardingWizard.tsx

key-decisions:
  - "TelegramStep uses onNext/onBack props (not onEnable/onSkip) to match the rootDir step pattern rather than VoiceStep pattern"
  - "Continue button disabled until botUsername is set; Skip always available to not block onboarding"
  - "Root Directory step Back button now navigates to step 5 (Telegram) instead of step 4 (Voice)"

patterns-established:
  - "Onboarding wizard steps: insert between existing steps by shifting subsequent step numbers"
  - "Token validation step pattern: validate first, then enable Continue; Skip always bypasses"

# Phase 38 Plan 03: Telegram Onboarding Step Summary

**TelegramStep component with BotFather numbered instructions, live token validation via POST /api/telegram/token, inserted as step 5 in a 7-step NexusOnboardingWizard**

## Performance

- **Duration:** 15 min
- **Started:** 2026-04-03T00:00:00Z
- **Completed:** 2026-04-03T00:15:00Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Created TelegramStep.tsx with numbered BotFather setup instructions and token input
- Live token validation via POST /api/telegram/token with success/error state
- Inserted TelegramStep as step 5 in NexusOnboardingWizard, shifting Root Directory to step 6 and Summary to step 7
- Updated step indicator to "Step N of 6" and all navigation callbacks to use correct step numbers

## Task Commits

1. **Task 1: Create TelegramStep onboarding component** - `d9d6e4f6` (feat)
2. **Task 2: Insert TelegramStep into NexusOnboardingWizard as step 5** - `48f708d9` (feat)

## Files Created/Modified

- `ui/src/components/onboarding/TelegramStep.tsx` - New step component: BotFather instructions, token input, validate/skip/back/next navigation
- `ui/src/components/NexusOnboardingWizard.tsx` - Updated to 7-step flow with TelegramStep at position 5

## Decisions Made

- TelegramStep uses `onNext`/`onBack` props instead of `onEnable`/`onSkip` (VoiceStep pattern) — more semantically correct for a step with conditional progression
- Continue button requires successful validation; Skip bypasses without saving — ensures onboarding is never blocked
- botUsername/bot_username dual-key access on validation response for API flexibility

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

The worktree at `agent-af62765c` is on an older branch. Work was performed in the main `/opt/nexus` repo on `gsd/phase-38-telegram-bridge` which has the 6-step wizard from prior phases. This is the correct execution target.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- TelegramStep component is ready for visual testing
- Token validation requires the POST /api/telegram/token endpoint from plan 38-01 to be deployed
- nexus-settings already has telegramToken field from Phase 36 — persisting the validated token to settings is a future enhancement
