Install

Clone https://github.com/to-nexus/skill-cross-shop into a temporary directory and run the install.sh script inside it to install the skill-cross-shop skill into my Claude Code environment. Tell me the result in one line when you're done.
  1. Save the game UUID locally in .env for authenticated shop reads.
  2. For personal testing, keep the payment signer config in the skill .env.
  3. For team, hosted-agent, or production funds, prefer Vault/KMS/HSM-backed signing.

Heads-up: CROSS Shop runs on local agent runtimes only — see the Where it runs section for the supported list. Hosted chat environments cannot execute this skill.

Safety & credentials

Off-chain session + on-chain payment

  • 🟣 Off-chain session token + 🔴 PK signs the payment tx.
  • Required credentials: <GAME>_UUID — per-game account UUID.
  • Local signer config is needed when calling purchase.

Troubleshooting

›phase_1_not_captured?
Write commands are disabled until references/games.json is populated. Use games only for now.
›Still getting 401 after login?
UUID typo, or the game account is not yet linked to cross.shop.
