Installation

Requirements

• An AI coding assistant: Claude Code, Cursor, Codex, or GitHub Copilot
• Git

No other dependencies. Skills are pure markdown instructions — no Python, Node, or other runtime needed.

Install methods

Claude Code plugin (recommended for Claude Code)

From within Claude Code, first add the marketplace:

/plugin marketplace add jorgeferrando/sdd-skills

Then install the plugin:

/plugin install sdd-skills@sdd-skills

This installs all 16 skills directly from the repository using the Claude Code plugin system. The skills become available across all your projects.

One-liner (all tools)

curl -fsSL https://raw.githubusercontent.com/jorgeferrando/sdd-skills/main/install-skills.sh | bash

The installer auto-detects your AI tool, or you can specify it:

./install-skills.sh --claude    # Claude Code
./install-skills.sh --cursor    # Cursor
./install-skills.sh --codex     # Codex (OpenAI)
./install-skills.sh --copilot   # GitHub Copilot

SkillKit (Multi-Agent)

Install across 45+ AI agents (Claude, Cursor, Copilot, Windsurf, Codex, Devin, and more):

npx skillkit install jorgeferrando/sdd-skills
skillkit sync

Manual install

git clone https://github.com/jorgeferrando/sdd-skills
cd sdd-skills
./install-skills.sh

Where skills are installed

Tool	Skills destination	Context file
Claude Code	~/.claude/skills/ or .claude/skills/	CLAUDE.md
Cursor	.cursor/rules/sdd/	.cursor/rules/sdd.md
Codex	.sdd/skills/	AGENTS.md
GitHub Copilot	.github/sdd/	.github/copilot-instructions.md

After installing

1. Restart your editor to load the new skills
2. Verify with /sdd-init — it should run without errors
3. All /sdd-* commands are now available

Updating

Re-run the installer. It skips skills that already exist — delete a skill directory to force reinstall:

./install-skills.sh

Uninstalling

Remove the skills directory for your tool (see table above).
