PC Stacks flags agent invocation logging

- PC Stacks recommends making 'tool invocation' events first-class in observability so teams know which tools an AI agent called, when, and with what inputs and outputs. - The piece reframes observability from simple request telemetry to workflow traceability across models, APIs, databases and external services. - That shift aligns with rapid market growth in observability platforms as teams demand accountability for autonomous agent behavior.
