Install the ExChek skill

Claude Code (and compatible Claude environments) can install the ExChek skill from the repo to classify items via the API with Adjudicator-in-the-Loop.

Install in Claude Code

Claude Code looks for skills in ~/.claude/skills/ (personal) or .claude/skills/ (project). Add the ExChek skill so Claude can run /exchek-classify or classify items when you ask.

  1. Copy the skill into Claude’s skills directory. From the public skill repo (recommended):
    git clone https://github.com/mrdulasolutions/exchekskill ~/.claude/skills/exchek-classify
    Or, if you have the full ExChek repo: copy the exchek-skill folder contents into ~/.claude/skills/exchek-classify/.
  2. Ensure your wallet is authenticated (see Funding).
  3. Fund the wallet with USDC on Base (Coinbase, Pay Sponge, or another gateway).
  4. Ask Claude to classify an item, or run /exchek-classify; the skill will call the API and guide you through the AITL flow.

The skill instructs Claude to always try start-free first, call api.exchek.us endpoints, relay prompts to you, and send your confirmations or feedback back to the API until the classification is approved and the report is generated. It includes error handling (e.g. 402: ask how to pay; 404: start over), when-to-use triggers, and support for cancel/start over. Claude can call POST /api/classify/status with your jobId to recover context if needed.
