Agentic AI · Amazon Web Services

CircuitCare AI Support

An agentic support system for a fictional electronics retailer. Grounded knowledge, cross-session memory, approved Gateway tools, restricted browsing, and isolated calculations assist customers while trusted application rules retain authority over identity, ownership, eligibility, and every business change.

Role: Architecture and end-to-end implementation
Evidence: Local, CI, and bounded AWS lifecycle verified
Boundary: No continuously hosted environment

The system

Customers sign in, see only their own orders, ask grounded support questions, confirm eligible returns, and follow safety cases. Staff use a separate queue to resolve escalations.

The language model explains and assists. Cognito identity, DynamoDB records, and deterministic application rules decide what a person may see or change. This separation prevents a persuasive model response from bypassing ownership or transaction controls.

Architecture

Assistance and authority remain separate

Three fictional identities exercised customer isolation, returns, safety escalation, staff resolution, grounding, Gateway, Memory, Browser, and Code Interpreter in AWS on 8 September 2026. All project resources were removed after validation.

Engineering decisions

Deterministic authority: return eligibility, confirmation, idempotency, and audit decisions stay outside the model.
Bounded capabilities: AgentCore receives approved knowledge, memory, narrow Gateway tools, restricted research, and isolated calculations.
Evaluation: 30 versioned scenarios combine with automated invariants and live adversarial checks.
Operational lifecycle: deployment, teardown, and residual-resource checks are part of acceptance.
