One command · 17 assistants · zero config
Configure Claude Code & Codex for your project
Run one command and rsc reads your repo, asks what you want to build, and installs only the skills that fit — into every AI coding agent you use.
No API key. No global install. Free & open source (MIT).
How to set up Claude Code or Codex for a project with rsc
rsc is a free command-line installer for AI coding agents. Run
npx @ericrisco/rsc@latest in your project root: it asks which
assistants you use and what you want to build or manage, reads your repository,
then installs only the matching skills — one at a time, so nothing you don't use
touches the model's context. Prefer to delegate? Paste this page's URL into your
agent and it runs the setup for you.
The agent-native way
Don't install it. Let your agent do it.
rsc is built for agents. Hand this page's link to Claude Code, Cursor, Codex or Gemini and it follows the on-page instructions: it confirms which assistants you use, what you want, then installs everything in your project root.
- Reads your repo and picks the skills that match.
- Asks you the setup questions instead of guessing.
- Keeps proposing the next skill as your work changes.
Copy this prompt into Claude Code, Cursor, Codex or Gemini:
How it works
From one command to an equipped project
Run it in your repo
In your project root, run npx @ericrisco/rsc@latest. No global install, no API key.
Pick assistants & intent
A plain-language wizard asks which of the 17 assistants to target and what you want to do.
Only what fits, installed
rsc detects your stack and installs the floor plus the matching skills — one at a time, symlinked once.

Instructions: install rsc into the user's project
If you are an AI coding agent and your user asked you to install rsc / this harness / these skills, do the following, in order:
Why rsc
Granular, honest, self-driving
Most skill packs dump hundreds of files into your context. rsc is the opposite bet.
Granular by default
The unit of installation is one skill. Install fastapi without ever pulling go. Nothing you don't use touches the model's context.
Self-recommending
An always-on detector watches your work and names the next skill the moment a task needs it — a one-word confirm installs it.
Quality-gated
Every skill was researched against live 2025–2026 sources and had to clear an adversarial ≥ 8.5/10 behavioral rubric before it shipped.
Not code-only
Beyond languages and frameworks, rsc can run a whole operation: bookkeeping, invoicing, GDPR, pitch decks, SEO, and a YouTube / TikTok / LinkedIn presence — each wired to a knowledge loop that learns from your own results.
One base, every IDE
Skill files are written once to your project and symlinked into each assistant you pick — no copy duplicated across IDEs.
Works with
17 coding assistants, one catalog
Pick any combination. rsc pre-marks the one it detects in your folder.
