railway

railway is a skill for Claude Code from onsager-ai/dev-skills. It costs 289 tokens per session (5,467 once invoked), scanned A, original, MIT.

A command-line assistant for managing applications hosted on Railway, a cloud platform for running apps.

In plain words
What is it for?
It helps deploy code, investigate failed builds or crashes, inspect requests and metrics, change environment variables, restart or roll back services, run commands, and connect to containers.
Why use it?
It brings deployment, logs, settings, metrics, and container access into one workflow, so you do not have to switch between separate tools.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is railway run --service api --environment production -- node scripts/migrate.js.

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

railway 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/debug.sh, scripts/preflight.sh, scripts/smoke.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.

How it starts

The opening of the file, as written. The whole thing — 347 lines — stays where its author put it; the contents beside it link to each section on GitHub.

railway

One skill for the full Railway operator loop: status → debug → fix → deploy → verify. It wraps the railway CLI in a non-interactive, JSON-first style that an agent can drive without prompts, and it leans on RAILWAY_TOKEN from the environment instead of an interactive railway login.

This skill is repo-agnostic. It assumes the project is hosted on Railway (railway.com) and that a RAILWAY_TOKEN is exported in the environment. It makes no assumptions about the stack (Node, Python, Go, Docker, Nixpacks/Railpack — Railway's builder figures it out).

When this skill triggers

Phrases that should route here:

  • Deploy / build
    • "deploy this to railway"
    • "push to railway", "ship to railway", "railway up"
    • "build is failing on railway", "why did my build fail"
  • Logs / debugging
    • "show me the railway logs", "tail the logs", "railway logs --since 1h"
    • "why is my service crashing on railway"
    • "show me the 500s on railway", "show http logs", "show slow requests"
    • "find the request id abc123 in railway logs"
  • Ops
    • "redeploy on railway", "restart the api service", "roll back the last deploy"
    • "scale my railway service", "remove the latest deployment"
  • State / discovery
    • "list my railway projects", "what services are in this project", "list deployments"
    • "what's the status of my railway project", "is my service healthy"
  • Variables
    • "set a railway env var FOO=bar", "list railway variables", "delete a railway var"
  • Run / connect
    • "run this script with railway production env", "open a shell with railway env"
    • "ssh into my railway service", "connect to my railway postgres / redis / mongo"
  • Metrics
    • "what's the cpu/memory on railway", "is my service hitting limits"
    • "p95 latency on railway", "request rate on /api"

Skip when:

  • The host is not Railway (Fly, Render, Vercel, AWS, …). This skill knows the railway CLI; it does not generalise.
  • The fix is a code change with no operational lever — let the normal dev-process skills handle the code; come back here once it's time to deploy or read logs.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

railway is a skill published in the GitHub repository onsager-ai/dev-skills (5 stars, last pushed 27d ago), licensed MIT. It adds 289 tokens to every session and 5,467 once invoked, about $0.0014 per session on Opus 5. 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 2026-08-31.
