Instructions by agent

Muse

Muse is Meta's personal AI agent (muse.ai). It picks up skills automatically from chat — just paste the command.

  1. Copy the command above.
  2. Paste it into your Muse chat (web, iOS, Android, or Mac app).
  3. Muse reads https://aisa.sh/skill.md, installs the Circle CLI, and walks you through wallet login and funding — asking your approval before anything is spent.
Each purchase gets its own approval in Muse. The agent shows you the endpoint, live price, and payer address before paying.

Claude Code

Install the skill file into Claude Code's skills directory, then invoke it by name or paste the command.

mkdir -p ~/.claude/skills/buy-aisa-x402 curl -sL https://aisa.sh/skill.md -o ~/.claude/skills/buy-aisa-x402/SKILL.md
  1. Run the commands above in your terminal.
  2. Start a new Claude Code session so it discovers the skill.
  3. Ask: "Connect to AIsa.one using https://aisa.sh/skill.md" — or trigger it any time with /buy-aisa-x402.
For a project-only install, use .claude/skills/buy-aisa-x402/ inside your repo instead.

Codex

Codex follows the open Agent Skills standard — drop the SKILL.md into its skills directory.

mkdir -p ~/.codex/skills/buy-aisa-x402 curl -sL https://aisa.sh/skill.md -o ~/.codex/skills/buy-aisa-x402/SKILL.md
  1. Run the commands above in your terminal.
  2. Restart Codex so it picks up the new skill (it auto-discovers ~/.codex/skills and .agents/skills).
  3. Ask: "Connect to AIsa.one using https://aisa.sh/skill.md" — or invoke explicitly with $buy-aisa-x402.

Cursor

Cursor reads SKILL.md natively — install it globally or per project.

FAQ

What does my agent need to pay?

A Circle agent wallet funded with USDC on the Arc blockchain. The skill walks through creating one with email login (no seed phrase) and funding it. Most API calls cost $0.10; flight bookings settle the full fare.

Is my spending protected?

Yes. The skill requires the agent to show you the endpoint, live price, and payer address — and get your explicit approval — before every purchase.
