export const PLAN_MODE_SERENA_GUIDANCE = "Tool selection for code research: for source files, symbols, functions, classes, declarations, references, implementations, and refactors, use Serena before raw reads/searches. Use serena_get_symbols_overview for source-file outlines; serena_find_symbol for named functions/classes/methods/variables; serena_find_referencing_symbols before behavior changes or renames; and serena_find_declaration / serena_find_implementations for definitions, interfaces, and implementations. Use read for docs/config/non-code files, exact line ranges, or after Serena identifies the relevant code region. Prefer the dedicated ls/grep/find tools over shell commands. Strict single read-only shell commands run automatically; test, build, and package scripts require confirmation because they may modify files. Use grep/find for exact text or file searches when semantic lookup is not the right fit.";
