## 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:**
|
|
```markdown
|
|
# Workspace Context

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

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

|
|
- [Decision 2 with date and rationale]

# 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**Status:** [active/deprecated/superseded]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
