Skills in this repo

1Ast Grepast-grep is an agent skill that packages the ast-grep rule reference so solo builders and coding agents can write correct YAML rules for structural code search. ast-grep matches Abstract Syntax Tree nodes using patterns, node kinds, regex, and relational constraints instead of line-oriented text search. The skill walks through atomic rules on single nodes, relational rules for parent/sibling ordering, and composite rules that combine sub-rules with logical AND, OR, and NOT. For indie builders shipping with Claude Code, Cursor, or Codex, that reference matters when you automate refactors, custom lint checks, security-oriented matchers, or repository-wide audits without fragile regular expressions on source text. Use it whenever you need metavariables, nested rule objects, or clarity on which positive keys must appear in a valid rule. Complexity is advanced because small YAML mistakes silently miss nodes; this skill reduces trial-and-error when integrating ast-grep into CLI pipelines or agent tooling during build, and when reusing the same rules in ship and operate workflows.7.8kinstalls
