Story 1.2: Context Persistence Framework

Status

Complete - 100% Complete (Enterprise-Grade Implementation)

Story

As a BMAD agent working in a collaborative session,
I want to automatically capture and persist critical development context in structured formats,
so that other agents and future sessions can access complete collaborative history without losing decisions or progress.

Acceptance Criteria

  1. Structured Context Files

    • Implement shared context file format in .workspace/context/shared-context.md
    • Create decisions logging in .workspace/decisions/decisions-log.md
    • Build progress tracking in .workspace/progress/progress-summary.md
    • Establish quality metrics storage in .workspace/quality/quality-metrics.md

  2. Automatic Context Capture

    • Implement context capture hooks for agent operations
    • Create decision logging when architectural choices are made
    • Build progress tracking that updates during story development
    • Establish quality metrics capture during audits and validations

  3. Context Retrieval System

    • Implement context loading for new sessions
    • Create decision history lookup functionality
    • Build progress restoration for interrupted workflows
    • Provide quality metrics access for continuous improvement

  4. Context Compaction Management

    • Implement context size monitoring with configurable thresholds
    • Create intelligent summarization preserving key decisions
    • Build archival system in .workspace/archive/ with date-based organization
    • Establish context restoration from archived summaries

  5. Integration with BMAD Agents (Cross-IDE)

    • Extend agent commands to include context persistence across all supported IDEs
    • Integrate with *develop-story command for progress tracking (Claude Code) and file-based progress tracking (other IDEs)
    • Connect with *reality-audit for quality metrics storage
    • Update agent handoff procedures to use persistent context with IDE-agnostic file operations
    • Provide context persistence hooks for both native commands and utility script workflows

Tasks / Subtasks

  • Create Structured Context File System (AC: 1)

    • Design shared-context.md format with session info, current focus, key decisions, and next steps
    • Implement decisions-log.md with decision tracking, rationale, and impact assessment
    • Build progress-summary.md with story status, completed tasks, and blockers
    • Create quality-metrics.md with audit scores, pattern compliance, and improvement trends

  • Implement Automatic Context Capture (AC: 2)

    • Create context capture middleware for agent command execution
    • Build decision logging triggers for architectural and design choices
    • Implement progress tracking hooks for story and task completion
    • Add quality metrics capture during reality audits and QA validations

  • Build Context Retrieval System (AC: 3)

    • Implement context loading function for session initialization
    • Create decision lookup by date, agent, and topic
    • Build progress restoration for resuming interrupted workflows
    • Add quality metrics querying for trend analysis and improvement

  • Develop Context Compaction Management (AC: 4)

    • Implement context size monitoring (trigger at 10MB per context file)
    • Create intelligent summarization algorithm preserving decisions and blockers
    • Build archival system with compressed historical context
    • Add context restoration capability from archived summaries

  • Integrate with BMAD Agent Framework (Cross-IDE) (AC: 5)

    • Extend dev agent *develop-story command with progress persistence (Claude Code native)
    • Create file-based progress tracking hooks for non-Claude Code IDEs
    • Integrate QA agent *reality-audit with quality metrics storage across all IDEs
    • Update agent handoff procedures to read/write persistent context using IDE-agnostic file operations
    • Add context awareness to existing agent commands with graceful degradation for non-workspace users
    • Implement context persistence utilities callable from Node.js scripts for cross-IDE support

Dev Notes

Context Persistence Architecture

Design Philosophy:

  • Incremental capture: Context builds gradually through agent operations
  • Structured storage: Consistent markdown format for human readability and agent parsing
  • Intelligent compression: Preserve critical decisions while summarizing routine progress
  • Session continuity: New sessions can resume with full context understanding

Context File Formats:

shared-context.md:

# Workspace Context
**Last Updated:** [timestamp]
**Active Sessions:** [session-ids]
**Primary Agent:** [current-agent]

## Current Focus
[Current development focus and active story]

## Key Decisions
- [Decision 1 with date and rationale]
- [Decision 2 with date and rationale]

## Next Steps
- [Priority action items]
- [Pending handoffs]

## Session Notes
[Agent-specific notes and observations]

decisions-log.md:

# Architectural & Design Decisions

## Decision 001: [Decision Title]
**Date:** [timestamp]
**Agent:** [deciding-agent]
**Context:** [story or situation context]
**Decision:** [what was decided]
**Rationale:** [why this decision was made]
**Alternatives:** [other options considered]
**Impact:** [expected impact on project]
**Status:** [active/deprecated/superseded]

Progress Integration Points:

  • Hooks into *develop-story for task completion tracking (Claude Code CLI)
  • File-based progress tracking for other IDEs through workspace utilities
  • Integration with *reality-audit for quality metrics persistence across all development environments
  • Connection to agent handoff procedures for context transfer using IDE-agnostic file operations
  • Compatibility with existing BMAD installer for automatic setup
  • Graceful coexistence with TodoWrite tool and other existing progress tracking mechanisms
  • Cross-IDE context sharing through standardized markdown file formats

Performance Considerations:

  • Context files cached in memory during active sessions
  • Lazy loading of archived context only when explicitly requested
  • Asynchronous context persistence to avoid blocking agent operations
  • Intelligent context compaction triggered by file size thresholds

Testing

Testing Standards:

  • Test Location: /tmp/tests/context-persistence/
  • Test Framework: Node.js with built-in assert and fs modules
  • Mock Strategy: Mock file system operations and agent command hooks
  • Performance Testing: Verify context operations complete within 50ms

Specific Test Requirements:

  • Context Capture Testing: Verify automatic context capture during agent operations across different IDEs
  • Retrieval Testing: Test context loading and decision lookup functionality for both native commands and utility scripts
  • Compaction Testing: Validate intelligent summarization preserves critical information
  • Integration Testing: Test with actual BMAD agent commands and workflows across supported IDEs
  • Cross-IDE Testing: Verify context persistence works with Claude Code CLI, Cursor, Windsurf, and other supported IDEs
  • Concurrency Testing: Verify multiple sessions from different IDEs can read/write context safely
  • Recovery Testing: Test context restoration from corrupted or incomplete files
  • Installer Testing: Verify context persistence setup during BMAD installation process

Test Data:

  • Sample context files with various decision types and complexity levels
  • Mock agent command execution scenarios
  • Test archives with different compression ratios and content types
