# Sprint 6: Human in the Loop

**Status**: ✅ Complete
**Duration**: Week 6 (Completed 2025-11-14)
**Epic/Issues**: Sprint 6 beads issues (20 tasks completed)
**Pull Request**: [PR #18](https://github.com/frankbria/codeframe/pull/18) - Merged to main

## Goal
Enable agents to ask for help when blocked and resume work after receiving answers.

## User Story
As a developer, I want agents to ask me questions when stuck, answer via the dashboard, and watch them continue working.

## Completed Tasks

### Core Features (P0)
- [x] **Blocker creation and storage**
  - Agent creates blocker when stuck
  - Store in blockers table with project_id support
  - Classify as SYNC or ASYNC
  - All 3 worker agents (Backend, Frontend, Test) support blocker creation

- [x] **Blocker resolution UI**
  - BlockerModal component for answering questions
  - Submit answer via API (POST /api/blockers/{id}/resolve)
  - Update blocker status to RESOLVED
  - BlockerPanel shows all blockers for project
  - BlockerBadge displays blocker count

- [x] **Agent resume after blocker resolved**
  - Agents can resume work after receiving answers
  - WebSocket notifications for blocker resolution
  - Dashboard updates in real-time

### Enhancements (P1)
- [x] **SYNC vs ASYNC blocker handling**
  - SYNC: Critical blockers that require immediate attention
  - ASYNC: Non-blocking questions that can be answered later
  - Visual distinction in UI (different icons and colors)
  - Database supports both blocker types

- [x] **Notification system**
  - WebSocket real-time notifications for blocker events
  - Webhook notifications for critical blockers (configurable)
  - Blocker expiration cron job (24h timeout)

## Definition of Done
- [x] Agents create blockers when stuck
- [x] Blockers appear in dashboard with severity
- [x] Can answer questions via UI
- [x] Agents resume after answer received
- [x] SYNC blockers pause work, ASYNC don't
- [x] Notifications sent for SYNC blockers
- [x] Working demo of blocker creation → resolution → resume flow
