flyio

flyio is a skill for Claude Code from Arvo-AI/aurora. It costs 21 tokens per session (439 once invoked), scanned A, original, Apache-2.0.

An integration for Fly.io, a platform that runs applications on cloud machines. It supports application monitoring, machine management, metrics, logs, and incident response.

In plain words
What is it for?
It helps list and manage applications and machines, retrieve non-streaming logs, and query Prometheus metrics such as uptime, CPU, memory, network traffic, concurrency, and HTTP response performance.
Why use it?
It gives the agent a way to inspect and manage a Fly.io application during operational work, including checking its machines and recent behavior.

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 0 findings 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 6d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fly.io Integration

Overview

Fly.io is connected for application monitoring, machine lifecycle management, and incident remediation.

Instructions

How to interact

  • Use cloud_exec('flyio', '<fly command>') for all Fly.io CLI operations.
  • The CLI (flyctl) is pre-authenticated with the user's org-scoped token.
  • Always pass --json flag for structured output when available.

Prometheus metrics

Use query_flyio_metrics(query) for PromQL queries against Fly.io's Prometheus federation. Common metrics include (but are not limited to) fly_instance_up, fly_instance_cpu, fly_instance_memory_resident, fly_edge_http_responses_count, fly_edge_http_response_time_seconds_bucket, fly_instance_net_recv_bytes, fly_app_concurrency.

Critical rules

  • Always use cloud_exec('flyio', ...) -- never call the REST API directly.
  • Use -a <app_name> for commands that target a specific app (e.g. fly status -a myapp). Do NOT use -a on global commands like fly apps list, fly regions list.
  • Pass --json for structured output when available (not all commands support it -- if it fails, retry without).
  • For logs, always use --no-tail to avoid indefinite streaming (e.g. fly logs -a myapp --no-tail).

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.
