Why Service Metadata Should Be Machine-Generated, Not Hand-Written

Software engineer Anton, who is migrating a PHP monolith into Go microservices, identified a silent failure mode where Go's linker ignores an -X version flag if the target symbol is missing, causing binaries to silently report incorrect version metadata. This same pattern of undetected drift, he argues, applies to hand-written service documentation, which can quietly fall out of sync with the actual codebase without triggering any alerts or build failures. In his setup, service composition was already declared in a machine-readable manifest used by the runtime and deployment pipeline, but a separate prose description of the same service existed alongside it. After recognising the risk, he replaced the hand-written description with machine-generated artefacts — an environment variable catalog and a metrics snapshot — both derived directly from code and the manifest, committed to the repository, and verified by CI drift checks. His core argument is that a service description only stays accurate when it is produced by the system itself rather than maintained by a person.
