Frigg is the default for code discovery, file listing, navigation, exact code search, and bounded source reads.

Before using shell `rg`, `grep`, `find`, `fd`, `cat`, or `sed` for code exploration, use the matching Frigg MCP tool in attached or attachable code repositories.

Shell tools are fallback only for git state and diffs, non-code files, build/test output, generated or unindexed files, explicit live-disk verification, or when Frigg is unavailable.
