ast-grep-rule-crafter

Produces a ready-to-run ast-grep YAML rule that searches, lints, or auto-rewrites code via tree-sitter AST patterns, delivered with positive + negative fixtures and an exact validation command. Use for lint rules, codemods, code modernizations, and API migrations with auto-fix. Trigger whenever the user mentions ast-grep, sg scan, sgconfig, tree-sitter patterns, AST matching, structural search-and-replace, or a codemod — and ALSO when they describe the task without naming the tool, e.g. "find every call to X and rewrite it", "replace all console.log with logger across the repo", "write a lint rule for this pattern", "upgrade all usages of the old SDK", or "migrate this API everywhere". Chinese triggers: 写 ast-grep 规则, 结构化搜索替换, 批量改写代码, 代码迁移规则, codemod, 写个 lint 规则, 语法树匹配, 自动改写代码.
