error-handling

The skill content is coherently aligned with a dedicated error-handling framework. It provides a consistent taxonomy, a structured error class hierarchy for multiple languages, explicit propagation rules, a clear separation between user-facing and internal error information, and centralized middleware guidance. There are minor gaps in implementation specifics (edge correlation ID generation, multi-tenant considerations, and explicit observability formats), but none imply fundamental misalignment with the stated purpose. Overall, the footprint is proportionate to the goal of standardizing error handling in APIs and services, with low to moderate security risk and no evident credential/exfiltration patterns.
