A platform that deploys applications and databases directly from a code repository. It can run several services, such as a frontend, backend, and worker, from one repository.

Use it to deploy web apps, background workers, PostgreSQL, Redis, MongoDB, scheduled tasks, and multiple services in a monorepo.

It removes much of the infrastructure setup needed for a small application. Private networking lets services communicate without exposing every service publicly.

railway — Skill for Claude Code and Codex by G1Joshi

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add G1Joshi/Agent-Skills --skill railway

Clone the repo

git clone --depth 1 https://github.com/G1Joshi/Agent-Skills

Made for: Claude Code, Codex.

Per session 15 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 321 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00015	$0.00321
Opus 5	$0.00008	$0.00161
Sonnet 5	$0.00003	$0.00064
Haiku 4.5	$0.00002	$0.00032

Measured 9d ago against content hash 33c682c88fe9, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

railway 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 9d 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

Railway

Railway is a modern PaaS that offers "Infrastructure from Code". It introspects your repo and deploys it. Can also deploy Databases (Postgres, Redis, Mongo).

When to Use

Heroku Alternative: Cheaper and more modern interface than Heroku.
Databases: Spining up a private network with a Service and a Redis/Postgres DB is 1 click.
Monorepos: Excellent support for building multiple services (frontend, backend, worker) from one repo.

Quick Start (CLI)

railway login
railway init
railway up

Core Concepts

Services

Apps or Databases.

Canvas

A visual graph of your infrastructure showing usage and relationships.

Config as Code

railway.toml allows you to define build commands and deploy health checks.

Best Practices (2025)

Do:

Use Private Networking: Services communicate over private IP (IPv6). Explicitly expose only what needs public access.
Use Templates: One-click deploy "PostHog", "Metabase", "Cronicle".
Use Priority Boarding: For critical production apps, upgrade the plan to ensure capacity.

Don't:

Don't rely on ephemeral disk: Just like Heroku, filesystem is reset on deploy.

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 G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 15 tokens to every session and 321 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
