sei-skill Installation

Prerequisites

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

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?”

./install.sh --agent codex

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

./install.sh --agent cursor

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

./install.sh --agent copilot

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

./install.sh --agent windsurf

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

./install.sh --agent aider

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

./install.sh --agent openhands

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

./install.sh --agent gemini

Installs to GEMINI.md in your project root.

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

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

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

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