Replace with a clear description of what this skill does and when Claude should use it. Be specific about trigger words and use cases.
Use when deploying, configuring, troubleshooting, reviewing, or architecting Fly.io apps and infrastructure. Covers flyctl, fly.toml, Fly Launch, Fly Machines, process groups, health checks, deployment strategies, private networking, 6PN, Flycast, Fly-Src app-to-app auth, egress IPs, volumes, Managed Postgres, Tigris, Litestream, Redis, LiteFS, extensions, CI/CD, and production readiness.
Query GA4 reports (users, sessions, conversions, funnels, realtime), manage properties / data streams / key events / custom dimensions / audiences / access bindings, and send Measurement Protocol events via the `ga4` CLI. Use this skill whenever the user mentions GA4, Google Analytics, property IDs starting with `properties/`, tracking events, engagement or traffic metrics, attribution, conversions, key events, audiences, BigQuery links, access roles, or realtime users — even if they don't explicitly say "GA4". Do not use for Google Search Console (see google-search-console skill) or generic web analytics where the source isn't GA4 (ask first).
Query Google Search Console analytics, inspect URL indexing status, manage sitemaps, and run PageSpeed Insights audits. Use when the user needs SEO data, search performance reports, indexing diagnostics, or Core Web Vitals analysis.
Use for any Tailscale platform work: tailnets, tailscaled, tailscale CLI, grants and ACLs, MagicDNS, Serve, Funnel, Tailscale Services, app connectors, subnet routers, exit nodes, Tailscale SSH, Kubernetes Operator, containers, tsnet, auth keys, OAuth clients, CI/CD automation, API usage, GitOps policy workflows, connectivity debugging, and production diagnostics.
Manage Google Drive files with manifest-tracked push/pull workflows via rclone. Use when the user needs to download, upload, list, or manage files on Google Drive shared drives.
Use when upgrading, validating, or modernizing Node.js projects for Node.js 26, or when answering implementation questions about Node.js 26 features and compatibility. Covers Temporal enabled by default, V8 14.6 Map/WeakMap get-or-insert helpers, Iterator.concat, Undici 8, raw crypto key formats, removed/deprecated APIs, native addon rebuilds, platform minimums, and release/LTS readiness decisions.
Fill, redline, and generate PDFs with the right tool for the source. Detects AcroForm vs flat PDFs, handles AES-encrypted government forms, navigates appearance-stream gotchas, and verifies every output by rendering. Use when the user asks to fill a PDF form, redline a PDF, generate a PDF from markdown, or reproduce a packet of forms. PDF-only — DOCX, XLSX, and other formats are out of scope.
