• Evolve the MCP integration, capability catalog, and execution gateways.

• Design secure models for identity, consent, credentials, permissions, quotas, and revocation.

• Ensure idempotence, traceability, isolation, and proper handling of retries and partial failures.

• Create reproducible pipelines for building, verification, deployment, and rollback with immutable artifacts.

• Develop evaluation suites and end-to-end tests for prompts, models, tools, security, and runtime.

• Define security standards for generated code, dependencies, containers, networking, and supply chain.

• Investigate end-to-end incidents and correct structural root causes.

• Design SLOs, metrics, alerts, and operational dashboards.
