What this skill does

Instruments code so production behavior is visible and diagnosable. Use when adding logging, metrics, tracing, or alerting. Use when shipping any feature that runs in production and you need evidence it works. Use when production issues are reported but you can't tell what happened from the available data. Code you can't observe is code you can't operate. Observability is the ability to answer "what is the system doing and why?" from the outside, using the telemetry the code emits.

When it triggers

  • Use when adding logging, metrics, tracing, or alerting.
  • Use when shipping any feature that runs in production and you need evidence it works.
  • Use when production issues are reported but you can't tell what happened from the available data.
