Semantic code search — finds code by meaning. Use --deep for complex questions (one call, complete answer). Use --refs for simple lookups. --around for call graph. 25+ languages.
Generate and maintain repo documentation from semantex's deterministic docs scaffolds. Use when asked to document a codebase, write architecture docs, or keep docs in sync with code. Calls semantex_docs_context (no LLM inside semantex) — you write the prose.
