PR #784 Implementation Plan

Agent Handoff Workflows for Context Preservation

Status: Implementation Plan (Setup Phase)
Branch: feature/add-bmad-handoff-workflows-784
PR Number: 784
Author: Sallvainian
Date: 2025-10-21

Executive Summary

PR #784 adds a comprehensive Agent Handoff System to BMAD Core, enabling seamless context preservation between AI agent sessions through two production-ready workflows:

  1. /handoff - Create and save comprehensive context to Serena
  2. /handoff-receive - Load and display actionable handoff summary

Files Added: 11
Total Lines: 2,179
Dependencies: Serena MCP
Status: Ready for integration

Feature Overview

Problem Statement

Complex BMAD workflows spanning multiple agent sessions lose context between sessions:

  • Next agent doesn't know what was just completed
  • Key files and context not readily available
  • Success criteria unclear
  • Manual context reconstruction wastes time

Solution

Two production-ready workflows that work together to preserve and restore complete context with intelligent handoff selection, timestamped collision-proof naming, and comprehensive error handling.

Architecture

Workflow 1: /handoff (Create Handoff)

Purpose: Create comprehensive handoff memory and save to Serena

Flow:

  1. Validate workflow status file exists and has required fields
  2. Read workflow status and extract metadata (PROJECT_NAME, CURRENT_PHASE, NEXT_AGENT, NEXT_COMMAND)
  3. Extract completed work from status file or infer from context
  4. Activate Serena project
  5. Validate required fields present
  6. Generate structured handoff document with:
    • Work just completed
    • Current project state
    • Task for next agent
    • Key context (3-5 critical items)
    • Files to review (categorized)
    • Success criteria
    • Next steps
  7. Save to Serena with timestamped collision-proof name: [agent]-handoff-YYYY-MM-DD-HHmmss
  8. Output ready-to-use prompt for next session

Key Features:

  • Comprehensive metadata extraction
  • Intelligent context capture
  • Serena MCP integration
  • Collision-proof naming (timestamp precision to seconds)
  • Error recovery with user guidance

Workflow 2: /handoff-receive (Load Handoff)

Purpose: Load and display actionable handoff summary

Flow:

  1. Activate Serena project
  2. List all available handoff memories
  3. Apply intelligent selection algorithm:
    • Sort by timestamp (newest first)
    • Support both new (YYYY-MM-DD-HHmmss) and legacy (YYYY-MM-DD) formats
    • Match agent names with current phase when possible
    • Present numbered menu for manual selection if ambiguous
  4. Read selected handoff memory
  5. Validate handoff structure (required sections present)
  6. Display clean, actionable summary focusing on immediate next steps
  7. Offer interactive menu for next actions

Key Features:

  • Intelligent handoff selection (newest-first with agent matching)
  • Backward compatible with legacy format
  • Structure validation
  • Clean, scannable display format
  • Interactive menu for next steps

Timestamp Format & Naming Convention

New Format (Preferred - Collision-Proof)

Pattern: [agent]-handoff-YYYY-MM-DD-HHmmss

Examples:

  • dev-handoff-2025-10-20-150000 (3:00 PM)
  • architect-handoff-2025-10-19-161530 (4:15:30 PM)
  • sm-handoff-2025-10-20-091245 (9:12:45 AM)

Benefits:

  • Prevents collisions with multiple handoffs per day
  • Chronological sorting capability
  • Precise, deterministic naming

Legacy Format (Backward Compatible)

Pattern: [agent]-handoff-YYYY-MM-DD

Example: dev-handoff-2025-10-19

Handling: Time treated as 00:00:00 in selection algorithm

  2. Workflow status dependency - /handoff needs status file
  3. Single project - Doesn't support cross-project handoffs
  4. Terminal-based - No visual UI

Future Enhancements

  • Handoff versioning and rollback capability
  • Cross-project handoff support
  • Handoff search/filter capabilities
  • Analytics and reporting
  • Handoff templates for common scenarios
  • Web UI for handoff management
