❌ **Changed:** Redis key format: `empathy:coord:*` → `empathy:signal:*` - ✅ **New API:** `empathy_os.telemetry.CoordinationSignals` (Pattern 2 from Agent Coordination Architecture) **Migration Guide:** ```python # Before (v4.x - REMOVED): from empathy_os.memory import ShortTermMemory, AgentCredentials memory = ShortTermMemory() credentials = AgentCredentials("agent-1", AccessTier.CONTRIBUTOR) memory.send_signal("task_complete", {"status": "done"}, credentials, target_agent="agent-2") signals = memory.receive_signals(credentials, signal_type="task_complete") # After (v5.0 - NEW): from empathy_os.telemetry import CoordinationSignals from empathy_os.memory.types import AgentCredentials, AccessTier coordinator = CoordinationSignals(agent_id="agent-1") credentials = AgentCredentials("agent-1", AccessTier.CONTRIBUTOR) # Send signal (with permission check) coordinator.signal( signal_type="task_complete", target_agent="agent-2", payload={"status": "done"}, credentials=credentials # Required for security ) # Receive signals signals = coordinator.get_pending_signals(signal_type="task_complete") ``` **Benefits of Migration:** -

`ManageDocumentationCrew` → Use `empathy meta-workflow run manage-docs` - All deprecated workflows emit `DeprecationWarning` when instantiated - See [docs/CREWAI_MIGRATION.md](docs/CREWAI_MIGRATION.md) for migration guide ### Migration Notes **From v4.2.1**: No breaking changes. Existing code continues to work: - Tests using mock execution still work - Form engine without callback uses defaults (backward compatible) - Real execution only attempted when `mock_execution=False` - Deprecated workflows continue to work **To enable real execution**: ```python # Set ANTHROPIC_API_KEY environment variable # Then use mock_execution=False result = workflow.execute(mock_execution=False) ``` **To migrate from Crew workflows**: ```bash # Instead of using ReleasePreparationCrew empathy meta-workflow run release-prep # Instead of using TestCoverageBoostCrew empathy meta-workflow run test-coverage-boost ``` **Benefits of meta-workflows over Crew workflows**: - Smaller dependency footprint (no CrewAI/LangChain required) - Interactive configuration via Socratic questioning - Automatic cost optimization with progressive tier escalation - Session context for learning preferences -

Cache stats available via `workflow.get_cache_stats()` - Configure cache sizes in `empathy.config.yml` **Example:** ```python from empathy_os.pattern_library import PatternLibrary library = PatternLibrary() # Automatically uses O(1) index structures patterns = library.get_patterns_by_tag("debugging") # Fast! ``` --- ## [3.10.2] - 2026-01-09 ### Added - **🎯 Intelligent Tier Fallback: Automatic Cost Optimization with Quality Gates** - Workflows can now start with CHEAP tier and automatically upgrade to CAPABLE/PREMIUM if quality gates fail - Opt-in feature via `--use-recommended-tier` flag (backward compatible) - **30-50% cost savings** on average workflow execution vs. always using premium tier - Comprehensive quality validation with workflow-specific thresholds - Full telemetry tracking with tier progression history ```bash # Enable intelligent tier fallback empathy workflow run health-check --use-recommended-tier # Result: Tries CHEAP → CAPABLE → PREMIUM until quality gates pass # ✓ Stage: diagnose # Attempt 1: CHEAP → ✓ SUCCESS # # ✓ Stage: fix # Attempt 1: CHEAP → ✓ SUCCESS # # 💰 Cost Savings: $0.0300 (66.7%) ``` - **Quality Gate Infrastructure** ([src/empathy_os/workflows/base.py:156-187](src/empathy_os/workflows/base.py#L156-L187)) - New `validate_output()` method for per-stage quality validation - Default validation checks: execution success, non-empty output, no error keys - Workflow-specific validation overrides (e.g., health score threshold for health-check) - Configurable quality thresholds (default: 95% for health-check workflow) - **Progress UI with Tier Indicators** ([src/empathy_os/workflows/progress.py:236-254](src/empathy_os/workflows/progress.py#L236-L254)) - Real-time tier display in progress bar: `diagnose [CHEAP]`, `fix [CAPABLE]` - Automatic tier upgrade notifications with reasons - Visual feedback for tier escalation decisions - **Tier Progression Telemetry** ([src/empathy_os/workflows/tier_tracking.py:321-375](src/empathy_os/workflows/tier_tracking.py#L321-L375)) - Detailed tracking of tier attempts per stage: `(stage, tier, success)` - Fallback chain recording (e.g., `CHEAP → CAPABLE`) - Cost analysis: actual cost vs. all-PREMIUM baseline - Automatic pattern saving to `patterns/debugging/all_patterns.json` - Learning loop for future tier recommendations - **Comprehensive Test Suite** ([tests/unit/workflows/test_tier_fallback.py](tests/unit/workflows/test_tier_fallback.py)) - 8 unit tests covering all fallback scenarios (100% passing) - 89% code coverage on tier_tracking module - 45% code coverage on base workflow tier fallback logic - Tests for: optimal path (CHEAP success), single/multiple tier upgrades, all tiers exhausted, exception handling, backward compatibility ### Changed - **Health Check Workflow Quality Gate** ([src/empathy_os/workflows/health_check.py:156-187](src/empathy_os/workflows/health_check.py#L156-L187)) - Default health score threshold changed from 100 to **95** (more practical balance) - Configurable via `--health-score-threshold` flag - Quality validation now blocks tier fallback if health score < threshold - Prevents unnecessary escalation to expensive tiers - **Workflow Execution Strategy** - LLM-level fallback (ResilientExecutor) now disabled when tier fallback is enabled - Avoids double fallback (tier-level + model-level) - Clearer separation of concerns: tier fallback handles quality, model fallback handles API errors ### Technical Details **Architecture:** - Fallback chain: `ModelTier.CHEAP → ModelTier.CAPABLE → ModelTier.PREMIUM` - Quality gates run after each stage execution - Failed attempts logged with failure reason (e.g., `"health_score_low"`, `"validation_failed"`) - Tier progression tracked: `workflow._tier_progression = [(stage, tier, success), ...]` - Opt-in design: Default behavior unchanged for backward compatibility **Cost Savings Examples:** - Both stages succeed at CHEAP: **~90% savings** vs. all-PREMIUM - 1 stage CAPABLE, 1 CHEAP: **~70% savings** vs. all-PREMIUM - 1 stage PREMIUM, 1 CHEAP: **~50% savings** vs. all-PREMIUM **Validation:** - Production-ready with 8/8 tests passing - Zero critical bugs - Zero lint errors, zero type errors - Comprehensive error handling with specific exceptions - Full documentation: [TIER_FALLBACK_TEST_REPORT.md](TIER_FALLBACK_TEST_REPORT.md) ### Migration Guide **No breaking changes.** Feature is opt-in and backward compatible. **To enable tier fallback:** ```bash # Standard mode (unchanged) empathy workflow run health-check # With tier fallback (new) empathy workflow run health-check --use-recommended-tier # Custom threshold empathy workflow run health-check --use-recommended-tier --health-score-threshold 90 ``` **Python API:** ```python from empathy_os.workflows import get_workflow workflow_cls = get_workflow("health-check") workflow = workflow_cls( provider="anthropic", enable_tier_fallback=True, # Enable feature health_score_threshold=95, # Optional: customize threshold ) result = await workflow.execute(path=".") # Check tier progression for stage, tier, success in workflow._tier_progression: print(f"{stage}: {tier} → {'✓' if success else '✗'}") ``` **When to use:** - ✅ Cost-sensitive workflows where CHEAP tier often succeeds - ✅ Workflows with clear quality metrics (health score, test coverage) - ✅ Exploratory workflows where quality requirements vary - ❌ Time-critical workflows (tier fallback adds latency on quality failures) - ❌ Workflows where PREMIUM is always required --- ## [3.9.3] - 2026-01-09 ### Fixed - **Project Health: Achieved 100/100 Health Score** 🎉 - Health score improved from 71% → 100% through systematic fixes -
