What is it?
This repository is a set of installable skills for Claude Code, the coding agent from Anthropic. Each skill is a packaged instruction set that adds a slash command, such as /rpi or /show-me, and is installed with the skills CLI via npx skills add humanlayer/skills --skill NAME.
The skills cover several parts of the development loop. The rpi skill researches a change, works through design choices with the user, and implements it from local documents, with options for design discussion, PRD plus TDD, technical design, or research followed by implementation. show-me explains a topic with diagrams and HTML artifacts, and visual-pr creates or updates pull requests with a visual outline for reviewers.
Other skills target project setup and agent configuration. improve-claude-md rewrites CLAUDE.md using conditional instruction blocks, narrow-react-prop-types tightens React prop types to live code paths, and build-iterated-agentic-loop and design-control-loop generate scheduled coding-agent workflows for GitHub Actions. The rpi skill also works in Codex as $rpi.
Key features
- 01Installs individually with npx skills add and a --skill flag.
- 02rpi runs research, PRD, technical design, and implementation phases, each in a fresh session by default.
- 03show-me produces concise diagrams and focused HTML artifacts.
- 04visual-pr creates or updates pull requests with a visual change outline.
- 05improve-claude-md restructures CLAUDE.md with conditional instruction blocks.
- 06Workflow skills generate GitHub Actions coding-agent loops with prompts and memory files.
Use cases
- Planning a feature with Claude Code by researching the codebase and writing a PRD before implementation.
- Helping reviewers understand a large pull request through a visual outline.
- Tidying an existing CLAUDE.md so the agent follows project rules more reliably.
- Setting up a scheduled coding-agent workflow in a GitHub repository.
Quick start
- 1
Install the rpi skill
npx skills add humanlayer/skills --skill rpi - 2
Invoke the skill with your task in Claude Code
/rpi research how the collections connect to the database
Things to know
- Each skill is installed separately with the --skill flag.
- Codex use needs write access to .agents/artifacts because its default sandbox can make .agents read-only.
