observability-and-instrumentation

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.

Skills are plain text instructions the agent follows, sometimes with scripts. Check the source, prefer repositories with many installs and stars, and read any script it ships.

Install

npx skills add addyosmani/agent-skills@observability-and-instrumentation

Runs in a terminal with Node.js 18 or newer. Add -y to skip the prompts and -g to install for every project instead of this one.

Install for your agent

npx skills add addyosmani/agent-skills@observability-and-instrumentation --agent claude-code -y

Start a new session afterwards so the agent picks the skill up. In Claude Code you can also call it directly with /observability-and-instrumentation.

What it does

Observability and Instrumentation Overview 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. Instrumentation is not a post-launch add-on — it's written alongside the feature, the same way tests are. If a feature ships without telemetry, the first user-reported bug becomes archaeology instead of a query. When to Use - Building any feature that will run in production - Adding a new service, endpoint, background job, or external integration - A production incident took…
