Provides tool selection guidance for code analysis using rg, ast-grep, jq, Glob, Read, and Sequential Thinking. Use when analyzing .ts, .js, .py, or other source files and need to choose the right search/analysis tool, combine multiple tools for complex workflows, or handle edge cases in code refactoring. Mention 'which tool', 'search vs grep', 'ast-grep vs ripgrep', or 'combine tools' to trigger. Primary consumers are code analysis agents.
