Legit codebase-indexing tool that actually reduces Claude's token spend by 35-70% — the benchmark claims are measurable and the architecture reasoning checks out.

This isn't marketing fiction: pre-indexing a codebase into a symbol graph + call graph is a genuine optimization for LLM-based code exploration. The benchmark methodology (4 runs median, headless Claude Code, raw numbers public) is rigorous enough to trust. Real wins on large repos (VS Code saves 72% tool calls, 35% cost). The index reduces wasteful grep/find loops that plague naive agents. Architecture is sound: tree-sitter parsing → SQLite FTS + relationship tables → MCP server. Installatio...
