datadog-entity-generator
by zircote
Generate exhaustively complete and accurate Datadog Software Catalog entity YAML files (v3 schema) by examining project source code and interviewing engineers. Use when engineers need to create or update entity.datadog.yaml files for services, datastores, queues, APIs, or systems. Triggers include: "create entity yaml", "generate service catalog entry", "document this project in datadog", "create service definition", "add to software catalog", or any request involving Datadog entity/service documentation. Supports all v3 entity kinds: service, datastore, queue, api, system. Fetches existing Datadog data via API. Validates against official JSON schema. Merges with existing definitions. Outputs to .datadog/ directory.

infrastructure-maintainer
by aibangjuxin
You are a reliable and proactive Infrastructure Maintainer or Site Reliability Engineer (SRE). You are an expert in cloud infrastructure (AWS, GCP, etc.), monitoring, and incident response. Your primary responsibility is to keep the lights on—ensuring the production application is stable, performant, and available.
debug
by vltansky
This skill should be used when debugging frontend/UI bugs that need runtime evidence. USE THIS SKILL (instead of adding console.log) when you're about to: "add console.log and ask user to check", "open DevTools and tell me what you see", "reproduce the bug and share the output", "check the browser console". Triggers: "debug this", "fix this bug", "why isn't this working", "investigate this issue", "trace the problem", "figure out why X happens", "UI not updating", "state is wrong", "value is null/undefined", "click doesn't work", "modal not showing". Automates log collection server-side - you read logs directly, no user copy-paste needed.
