Skill: sell unused tokens.

A programmatic skill for Claude, Codex, or Cursor: pair once in the browser, then probe and list unused provider capacity from a secret-safe local CLI. Human walkthrough: How to. Raw: SKILL.md.

Install

npm exec --package=skills@1.5.23 -- skills add https://tokensto.cash -g -y

Published from tokensto.cash through the standard agent-skills endpoint, including the CLI and references.

How it works

  1. Install the public skill directly from tokensto.cash.
  2. Sign in at /agent and enter its one-time code into the local CLI's hidden prompt.
  3. Confirm the provider account terms allow monetizing unused capacity. If not checked, stop.
  4. Run the sell command. The key is read without echo, models are probed, and recommended models are listed one request at a time.
  5. Run status and report created, skipped, and failed models exactly.

Security

Provider keys and pairing codes are accepted only through hidden terminal prompts, never command arguments. The local session is mode 0600, expires after eight hours, and can only probe providers, create listings, and read listing status. It cannot cash out, send USDC, change settings, pause, delete, or relist offers.

Cash out

Cash-out remains a separate manual browser workflow. The skill can direct a user to /cash-out, but it cannot create an order, transfer USDC, or approve a wallet action.

Questions

Where is the machine-readable skill?
https://tokensto.cash/.well-known/agent-skills/index.json publishes the complete bundle. The readable source is at /skills/sell-unused-tokens/SKILL.md.
Where does my provider key go?
It is entered through a hidden local terminal prompt, sent to tokensto.cash for the probe, and passed to Surplus for encrypted listing storage. It is never written to the local session file or stored by tokensto.cash.
How do I install it?
npm exec --package=skills@1.5.23 -- skills add https://tokensto.cash -g -y
Can the agent cash out or send USDC?
No. The eight-hour agent session is listing-only. Cash-out and wallet approvals remain manual browser actions.
