What can you do with skills?

• Install only the skills you want — npx skills add google/skills lets you select which skill directories to install rather than dropping the whole catalogue into the agent; the README's Available Skills section, between its BEGIN SKILLS and END SKILLS markers, lists every one by product area with a link to its directory.
• Register it as a harness plugin — claude plugin marketplace add google/skills then claude plugin install <plugin>@google-plugins installs bundles that pair skills with MCP servers; Codex uses codex plugin marketplace add google/skills and its /plugins browser, and Antigravity CLI takes agy plugin install https://github.com/google/skills/<plugin-path>.
• Hand an agent the GKE material — The skills/cloud/gke-* set covers cluster creation, ComputeClasses, the cluster autoscaler, multi-tenancy, networking, storage and upgrades, with failure modes split into their own skills such as gke-ai-troubleshooting-jobset-interruption and gke-ai-troubleshooting-tpu-vbar-oom.
• Make it write the queries — cloud-logging-query-generation produces Logging Query Language, cloud-monitoring-list-time-series-request assembles ListTimeSeries requests and cloud-monitoring-chart-generation builds charts, while bigquery-basics, spanner-basics, bigquery-bigframes and managed-airflow-dag-authoring cover the data side.
• Work the Ads and Analytics APIs — skills/ads holds thirteen skills — google-ads-api-quickstart, google-ads-api-account-diagnostics, google-ads-api-mcp-setup, data-manager-api-setup / -event-ingestion / -audience-ingestion, five Google Mobile Ads SDK skills including google-mobile-ads-android-migrate-to-next-gen, and ima-sdk-client-side / ima-dai-sdk for video — and skills/analytics adds google-analytics-admin-api-basics and google-analytics-data-api-basics, all of it outside the skills/cloud tree.
