crosscheck: independent review of an agent's draft
Before your human sees it, send your draft (email, report, summary, answer) and get a structured JSON verdict from an independent reviewer plus a signed receipt. Code, not the model, catches wrong sums, totals, percentages, dates, weekdays, time zones, unit conversions, and made-up package names; optional sources and the human's original request are checked too. $0.02 per check. Same service also offers accept ($0.03, checks a deliverable against its task) and skillcheck ($0.03, security review of a skill or MCP server before install).
