Apply this skill when self-hosted Coolify or Coolify Cloud servers, applications, services, databases, build servers, destinations, Docker Compose stacks, domains, TLS certificates, Traefik or Caddy proxies, health checks, rolling updates, preview deployments, environment variables, build secrets, API tokens, teams, backups, restores, updates, monitoring, cleanup, resource limits, networking, firewalls, or deployment and rollback behavior are created, changed, reviewed, diagnosed, migrated, secured, or operated.
Apply this skill when PostgreSQL-specific schema, query, transaction, migration, indexing, extension, role, row-level security, connection pooling, replication, backup, restore, managed Postgres, or runtime behavior is created, changed, reviewed, or reported, including PostgreSQL 18 asynchronous I/O, B-tree skip scan, UUIDv7, virtual generated columns, RETURNING OLD/NEW, OAuth, logical-replication conflicts, observability, or 17-to-18 upgrades.
Apply this skill when Ubuntu Server or Ubuntu cloud images, especially Ubuntu 24.04 LTS or 26.04 LTS, are installed, upgraded, tuned, secured, diagnosed, backed up, restored, rebooted, or operated, including APT, dpkg, Snap, PPA, deb822 sources, unattended-upgrades, phased updates, needrestart, Livepatch, kernels, systemd services and timers, journald, cgroup v2, PSI, sysctl, CPU, memory, storage, network, SSH socket activation, AppArmor, UFW, Docker or Podman host integration, release upgrades, and remote recovery.
Apply this skill when deciding whether an AI agent, workflow automation, internal tool, or operational integration is economically worth building, expanding, replacing, or retiring by comparing human touch and wait time, exception density, stable machine-readable boundaries, expected cost per accepted outcome, human alternatives, supervision, failure recovery, maintenance, break-even volume, throughput value, effective lifetime, NPV, and independent safety gates.
Apply this skill when production automation, scheduled jobs, cron, polling, webhooks, events, queues, workers, durable workflows, approval steps, connectors, or operational pipelines are designed, changed, reviewed, or reported and the task must choose trigger responsibilities, prevent missed or duplicate work, detect silent wrong results, place human approval at the irreversible boundary, minimize credentials and personal data, control useful-effect cost, and keep an owned versioned automation registry.
Apply this skill when cloud, infrastructure, Kubernetes, serverless, database, storage, logging, telemetry, CDN, NAT, egress, autoscaling, quota, budget, tagging, snapshot, container registry, Marketplace, LLM API, or third-party SaaS usage is created, changed, reviewed, or reported and the risk is whether normal, growth, or incident usage can silently explode spend without scenario bills, account or project isolation, quotas, tags, lifecycle, retention, caps, commitment discipline, or automated shutoff guardrails.
Apply this skill when a PRD, requirement, proposal, policy, operating procedure, game rule, system design, API contract, data model, code-change plan, review comment, decision memo, or agent answer needs consequence-driven critique that replaces vague praise, hedging, false balance, abstract adjectives, or unactionable criticism with an evidence-backed judgment, plausible competing readings, the first divergent decision, a concrete failure and late-discovery path, calibrated severity, a bounded correction, and an observable completion criterion.
Apply this skill when choosing, comparing, adding, replacing, upgrading, rejecting, or standardizing a technology stack, framework, runtime, database, cache, queue, auth provider, payment provider, AI provider, SDK, managed service, SaaS, hosting platform, deployment tool, build tool, ORM, observability tool, or vendor integration, especially when the decision depends on cost per accepted outcome, workload growth, saturation and tail performance, failure semantics, support and incident history, commitment pricing, migration and rollback, exit tax, lock-in, operating toil, or solo-maintainer survivability.
