| Structural patterns (functions, classes) | sg (ast-grep) | | Text/regex patterns (strings, names) | rg (ripgrep) | | File discovery by name/extension | fd |

Decision flow: Find files first? fd → pipe to rg/sg. Syntax-aware match needed? sg. Fast text search? rg. Uncertain? Start with rg, escalate to sg if structure matters.

ast-grep is the least familiar tool -- key syntax summarized here. See references/ast-grep.md for language-specific patterns and YAML rule files.
