Agent Skills: codebase-search

Semantic codebase search — use as the first step when exploring or scanning a codebase broadly. Understands code intent and traces cross-file flows. Use when the user needs to understand how code works, trace data flows, explore unfamiliar codebases, or answer conceptual questions ('how does X work', 'where is Y configured', 'trace the flow of Z'). Do NOT use for targeted keyword/symbol searches (use Grep) or file lookups (use Glob).
