Known Issues and Limitations
Current Limitations
-
Test Database Migration Required
- Integration tests written but not executed
- Need to apply workflow migration to test DB
- Tests are ready to run once DB is updated
-
Pack Auto-Loading Not Implemented
- Workflows must be created manually via API
- Pack installation doesn't auto-discover workflows
- Planned for Phase 1.6 (Pack Integration)
Future Enhancements (Not in Scope)
-
Workflow Validation API
- Validate workflow YAML before creating
- Dry-run mode for testing workflows
- Planned for Phase 1.6
-
Workflow Execution API
- Trigger workflow execution
- Query workflow execution status
- Planned for Phase 2 (Execution Engine)
-
Workflow Templates
- Pre-built workflow templates
- Workflow marketplace
- Future enhancement (Phase 3+)
Note: These are planned features, not blockers for Phase 1.5 completion
Next Steps
Immediate (Phase 1.6: Pack Integration)
Estimated Time: 5-8 hours
-
Auto-Load Workflows on Pack Install
- Call WorkflowLoader when pack is created/updated
- Register workflows automatically
- Update pack API handlers
-
Pack API Updates
- Add workflow count to pack summary
- Include workflow list in pack details
- Handle workflow cleanup on pack deletion
-
Validation Integration
- Validate workflow YAML during pack operations
- Return detailed error messages
- Support dry-run mode
Test Database Migration
Action Required: Apply workflow migration to test database
# Set test database URL
export DATABASE_URL="postgresql://attune_test:attune_test@localhost:5432/attune_test"
# Run migrations
sqlx migrate run
# Verify workflow tables exist
psql $DATABASE_URL -c "\dt attune.workflow*"
Expected Result: 14/14 integration tests pass
Long-Term (Phase 2+)
-
Execution Engine (2-3 weeks)
- Task graph builder
- Workflow executor service
- State machine implementation
-
Advanced Features (2-3 weeks)
- Variable scoping and templating
- Conditional logic and branching
- Parallel execution support
- Human-in-the-loop (inquiries)
Lessons Learned
What Went Well

- Minimal learning curve
- Consistent codebase structure
-
Comprehensive Planning
- Clear phase breakdown from design doc
- Well-defined acceptance criteria
