What it does
Rails Dev is an agent skill from pproenca/dot-skills. Ruby on Rails performance and maintainability optimization guidelines for building backend APIs and frontend web applications. This skill should be used when writing, reviewing, or refactoring Ruby on Rails code to ensure optimal patterns for controllers, models, ActiveRecord queries, caching, views, API design, security, and background jobs. Triggers on tasks involving Rails controllers, ActiveRecord queries, migrations, Turbo/Hotwire, API endpoints, background jobs, or Rails performance improvements.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 52 other files, including reference files and assets (for example `AGENTS.md`, `assets/templates/_template.md` and `metadata.json`).
It sits in Backend & APIs, covering Backend development, Background jobs and ORMs and data access. It works with Ruby on Rails. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.
When your agent uses it
- Tasks involving Rails controllers
- ActiveRecord queries
- Background jobs
- Rails performance improvements
Example prompts

Workflow steps
8 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Rails Dev loads about 1.9k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 547 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

When should I use Rails Dev?
Rails Dev fits situations like: tasks involving Rails controllers; activeRecord queries; background jobs; rails performance improvements.
How do I install Rails Dev in Claude Code?
Run `npx skills add pproenca/dot-skills --skill rails-dev -a claude-code`. Or copy the skill folder (skills/.curated/rails-dev in pproenca/dot-skills) into .claude/skills/rails-dev in your project. Claude Code loads it when a task matches its description.
How do I install Rails Dev in Codex?
Run `npx skills add pproenca/dot-skills --skill rails-dev -a codex`. Or copy the skill folder (skills/.curated/rails-dev in pproenca/dot-skills) into .agents/skills/rails-dev in your project. Codex loads it when a task matches its description.
Can I use Rails Dev in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pproenca/dot-skills --skill rails-dev -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rails-dev, .gemini/skills/rails-dev, .github/skills/rails-dev and .opencode/skills/rails-dev in your project.
What does Rails Dev need to run?
SKILL.md names no scripts, command-line tools or credentials: Rails Dev is instructions for the agent only.
Does Rails Dev access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Rails Dev safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Rails Dev use?
Rails Dev is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Rails Dev use?
About 1.9k tokens (SKILL.md is roughly 7.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 16k tokens, read only when the agent opens those files.
What are the alternatives to Rails Dev?
Skills that share tags, products or a category with Rails Dev: Laravel Specialist (Jeffallan/claude-skills, 12k stars), Rails Expert (Jeffallan/claude-skills, 12k stars), Rails Patterns (affaan-m/ECC, 274k stars) and Rails Idioms (irahardianto/awesome-agv, 157 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Rails Dev?
pproenca (a GitHub user) maintains it in pproenca/dot-skills, which has 214 GitHub stars. The repository holds 182 skills in this directory. The repository was last updated on August 15, 2026.
