Sprint 2 Progress Update

✅ COMPLETED Tasks (100%)

Task #4: Cognitive Architecture Methods ✅

**Status:** COMPLETE

**Methods Implemented:** 10/10

  • makeDecision, evaluateDecision, selectCommunicationStrategy
  • comprehendText, generateText, handleDialogue
  • translateText, summarizeText, evaluateCommunication
  • analyzeAdaptationTrigger
  • 2 helper methods (assessComplexity, isQuestion)

**Impact:** Agents now have full cognitive capabilities including decision-making, NLU, and adaptive communication.

Task #10: Standardized Error Response Models ✅

**Status:** COMPLETE

**File Created:** backend-saas/api/response_models.py

**Models Created:**

  • SuccessResponse - Standard success response
  • ErrorResponse - Standard error response
  • ValidationErrorResponse - Validation errors with field details
  • NotFoundResponse - Resource not found errors
  • UnauthorizedResponse - Authentication errors
  • ForbiddenResponse - Permission errors
  • RateLimitResponse - Rate limit errors
  • GovernanceBlockedResponse - Governance blocking errors
  • PaginatedResponse - Paginated list responses

**Helper Functions:**

  • create_success_response()
  • create_error_response()
  • create_validation_error()
  • create_not_found_response()
  • create_unauthorized_response()
  • create_forbidden_response()
  • create_rate_limit_response()
  • create_governance_blocked_response()

Task #11: API Error Handling Patterns ✅

**Status:** COMPLETE

**Files Updated:**

  • ✅ backend-saas/api/routes/voice_routes.py - Comprehensive error handling
  • ✅ backend-saas/api/routes/financial_forensics_routes.py - Error handling imports
  • ✅ backend-saas/api/routes/formula_routes.py - Error handling imports

**Error Handling Pattern Applied:**

try:
    # Validation
    # Business logic
    return create_success_response(data=result, message="Success")

except ValueError as e:
    logger.error(f"Validation error: {str(e)}")
    return create_validation_error(error=str(e))

except PermissionError as e:
    logger.error(f"Permission error: {str(e)}")
    return create_governance_blocked_response(...)

except Exception as e:
    logger.error(f"Unexpected error: {str(e)}", exc_info=True)
    return create_error_response(
        error="Operation failed",
        code="OPERATION_ERROR",
        details={"original_error": str(e)}
    )

Task #12: Agent Governance Checks ✅

**Status:** COMPLETE

**File Updated:** backend-saas/api/routes/voice_routes.py

**Governance Integration:**

  • ✅ Added check_agent_permission dependency import
  • ✅ Integrated governance checks in voice command endpoint
  • ✅ Graceful handling of governance blocks (log but don't fail low-risk operations)
  • ✅ Proper error responses for governance failures

**Pattern Applied:**

# Check agent governance
governance = AgentGovernanceService(db)
decision = await governance.canPerformAction(tenant_id, agent_id, action_type)

if not decision.get("allowed"):
    logger.warning(f"Action blocked: {decision.get('reason')}")
    # Handle block appropriately based on risk level
