Working on a large Rust codebase. The token problem is real — Claude Code will happily spend $5 of context just trying to understand how two modules relate before writing a single line. And once context compaction kicks in, it's even worse — the agent loses the thread completely and starts grepping the same files again from scratch.
Approaches I've tried:
Feeding CLAUDE.md / architecture docs manually — helps, but gets stale fast. Cursor's built-in indexing — breaks on monorepos, and I don't love proprietary code going to their servers. Basic MCP server with grep — works for exact matches, useless for semantic queries.
Eventually built something more serious: a local Tree-sitter indexer that builds a knowledge graph of file relationships and exposes it via MCP so agents query semantically instead of grepping blind. One tool call instead of 15 grep iterations. Published it here: https://github.com/Muvon/octocode
But genuinely curious what others are doing before I go deeper on it.
Three specific questions:
1. How do you handle the "ripple effect" problem — knowing that changing one file semantically affects others that aren't obviously linked?
2. Do you trust closed-source indexing with proprietary code, or have you gone local-first?
3. Has anyone gotten GraphRAG-style relationship mapping to work in practice at scale, or is it still mostly hype?
