- codexqa-testdata-generatoropenqa-cn/codexqaConstructs test data against real backends and writes it back into test cases as executable preconditions. Use whenever the user wants test data built, case materials or preconditions prepared, a data-build skill or tool reused, an API discovered, a construction script written, or a proven method recorded — including Chinese phrasings such as 构造测试数据, 准备测试数据, 造数据, 用例数据, 用例物料, 用例数据准备, 用例前置数据, 测试数据回写, 测试物料清单, 数据需求分析. Also use it for concrete requests that never say "test data", like "create this account from the OpenAPI", "build a script from these change APIs", "publish that script as a tool", or "scaffold a new domain from this OpenAPI directory". Not for authoring test cases from a PRD (that is codexqa-testcase-generator) or finding defects in code (that is codexqa-defect-analyzer). Bundled slots and sub-skills here are internal; reach them through this skill. Former skill name: testdata-generation.TestingNo warnings★ 234↓ —
