**REQUIRED for ALL Go code analysis.** NEVER use read_file, grep_search, or semantic_search directly on .go files for semantic understanding. ALWAYS use gopls-mcp tools first: go_definition (find definitions), go_references (find usages), go_hover (get types/docs), go_symbols (list symbols). Only use read_file AFTER gopls locates the code. This is MANDATORY for Go files - 5x more efficient and 100% accurate vs text-based tools.

Use when developing, fixing, reviewing, or refactoring any codebase where AI must produce reliable, observable, verifiable software with clear architecture, traceable execution paths, CI gates, and root-cause-oriented fixes rather than black-box changes.
