A quick reference for Fly.io, a platform that runs applications in containers and virtual machines across multiple regions.

In plain words
What is it for?
Use it to configure Fly.io application deployments, multi-region setups, persistent volumes, secrets, machines, and Fly Postgres.
Why use it?
It gathers deployment, regional distribution, secrets, storage, and database guidance for teams using Fly.io.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is COPY --from=builder /app/.next/static ./.next/static.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flyio scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 17 executable files (examples/background-worker/deploy.sh, examples/background-worker/tasks.py, examples/elixir-phoenix-liveview/deploy.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Fly.io Infrastructure Skills

Version: 1.0.0 | Target Size: <25KB | Purpose: Fast reference for Fly.io deployments and global application distribution

Overview

What is Fly.io: Modern platform-as-a-service (PaaS) for deploying applications globally with minimal configuration. Fly.io transforms containers into micro-VMs that run on physical hardware across 30+ regions worldwide.

When to Use Fly.io:

  • Simple to moderate applications requiring global distribution
  • Fast deployments without complex Kubernetes orchestration
  • Minimal operations overhead with PaaS simplicity
  • Edge computing and low-latency requirements (anycast routing)
  • Startup/SaaS applications with unpredictable traffic patterns
  • Databases requiring multi-region active replication (Fly Postgres)

When to Use Kubernetes Instead:

  • Complex microservices architectures with 10+ interdependent services
  • Existing Kubernetes expertise and tooling investment
  • Hybrid cloud or multi-cloud requirements (cloud-agnostic)
  • Advanced orchestration needs (service mesh, custom operators, advanced scheduling)
  • Enterprise compliance requirements (HIPAA, PCI-DSS on-premises)
  • Extensive third-party ecosystem integrations (Helm charts, operators)

Detection Criteria:

  • Auto-loads when fly.toml detected in project root
  • Manual: --tools=flyio flag
  • Use Case: Global application deployment with PaaS simplicity

Progressive Disclosure:

  • This file (SKILL.md): Quick reference for immediate use
  • REFERENCE.md: Comprehensive guide with advanced patterns and deployment strategies

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flyio is a skill published in the GitHub repository FortiumPartners/ensemble (11 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 6,521 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
