  Packaged Agent Skills generated from uChecker's published OpenAPI (split one-per-tag under
  openapi/; source in openapi/_original/uchecker-openapi.json). Every step is grounded in an
  operationId verified verbatim in the spec; cross-cutting rules cite ../authentication/,
  ../conventions/, ../errors/, ../asyncapi/, ../plans/ and ../rate-limits/. uChecker
  publishes no first-party skills or AGENTS.md — searched uchecker.net (569-URL sitemap),
  https://uchecker.net/llms.txt and https://uchecker.net/en/mcp; its agent surface is the
  hosted MCP server's 10 tools.
