sei-skill Installation

Install sei-skill for Claude Code, Cursor, GitHub Copilot, Windsurf, and other AI coding assistants.

Prerequisites

git clone https://github.com/sei-protocol/sei-skill
cd sei-skill

Install by agent

Claude Code

The default install targets Claude Code, placing the skill in ~/.claude/skills/sei/:

./install.sh

The skill loads automatically in every Claude Code session. To verify it’s active, ask: “What is the SSTORE gas cost on Sei testnet?”

Codex

./install.sh --agent codex

Installs to AGENTS.md in your project root. Codex CLI reads this file automatically.

Cursor

./install.sh --agent cursor

Installs to .cursor/rules/sei.mdc in your project. Cursor picks it up automatically as a rule file.

GitHub Copilot

./install.sh --agent copilot

Installs to .github/copilot-instructions.md. Copilot uses this file as custom instructions for the repository.

Windsurf

./install.sh --agent windsurf

Installs to .windsurf/rules/sei.md. Windsurf’s Cascade reads this automatically.

Aider

./install.sh --agent aider

Installs to ~/.aider/sei.md. Aider loads it as persistent context.

OpenHands

./install.sh --agent openhands

Installs to .openhands/SKILL.md in your project.

Gemini

./install.sh --agent gemini

Installs to GEMINI.md in your project root.

Variants

The full skill covers all three domains (contracts, frontend, ecosystem). If you only need one area, install a variant to keep context lean:

Variant	Command	Best for
Full (default)	./install.sh	General Sei development
Contracts	./install.sh --variant contracts	Smart contract engineers
Frontend	./install.sh --variant frontend	dApp and UI developers
Ecosystem	./install.sh --variant ecosystem	Infra, integrations, research

Combine with --agent to target a specific assistant:

./install.sh --agent cursor --variant contracts

Advanced options

Install to a project directory (instead of ~/.claude/):

./install.sh --project

Flatten to a single markdown file — useful for pasting into any chat interface or custom context:

./install.sh --flatten --output ./sei-context.md

Custom output path:

./install.sh --output /path/to/custom/location

Verify it’s working

After installing, test with a Sei-specific question that trips up unaugmented assistants:

• “What gas price should I use for transactions on Sei?”
• “Is PREVRANDAO a safe source of randomness on Sei?”
• “What’s the difference between sei1... and 0x... addresses?”

A Sei-aware assistant will give accurate, specific answers to all three.
