Usage:
codex_lens(action="init", path=".") # Index directory (auto-generates embeddings if available)
codex_lens(action="search", query="func") # Search code (auto: hybrid if embeddings exist, else exact)
codex_lens(action="search", query="func", mode="hybrid") # Force hybrid search
codex_lens(action="search_files", query="x") # Search, return paths only
Graph Enrichment:
codex_lens(action="search", query="func", enrich=true) # Enrich results with code relationships
Search Modes:
- auto: Auto-detect (hybrid if embeddings exist, exact otherwise) [default]
- exact/text: Exact FTS for code identifiers
- hybrid: Exact + Fuzzy + Vector fusion (best results, requires embeddings)
- fuzzy: Typo-tolerant search
- vector: Semantic + keyword
- pure-vector/semantic: Pure semantic search
