Two Claude Code plugins for large Unreal C++, Visual Studio, and .NET projects. Search the codebase through an official language server's index (clangd / Roslyn) instead of grep, and read tens-of-MB editor logs without dumping them into the conversation. Both cost about 99% fewer tokens than the naive approach. Local-only. No IDE required.

What it looks like

# Claude tries to grep code → the hook blocks it and points at the indexed tools:
$ grep -rn "SpawnActor" Source/**/*.cpp
🛑 [vs-token-safer] Code-symbol search via Bash. Use search_symbol / find_references
   instead (clangd/Roslyn index — semantic, token-capped).   # VTS_ENFORCE=0 to allow grep

▶ search_symbol "SpawnActor"
  func SpawnActor (in AGameMode)   @ Source/GameMode.cpp:142   (+2 more)
  → ~120 tokens   (grep would have dumped thousands of lines)

# A 1 MB editor log → parsed, deduped, classified (bundled gamedev-log-analyzer):
▶ /gamedev-log-analyzer:logs
  41,233 lines · 7 errors · 312 warnings
  ERROR   [LogStreaming] Failed to load asset <addr>         (×128)   @ AssetManager.cpp:210
  WARNING [LogPhysics]   Penetration depth <n> exceeds limit (×4,051) @ MyComponent.cpp:88
  → ~130 tokens   (raw log ≈ 267,000)

Sound familiar?

• grep on a giant Unreal C++ or .NET repo floods the context. Searching through clangd/Roslyn's index instead stays token-capped, around 97–99% smaller (benchmarks).
• A 50 MB editor log is unreadable as-is. Parsing, deduplicating, and classifying it brings it down to a few hundred tokens.
• Claude keeps reaching for grep on code. A hook catches that and points it at the indexed tools.
• Unlike an IDE-proxy approach, the language server runs headlessly — no editor needs to be open.

---

A Claude Code plugin that routes symbol search, find-references, and go-to-definition through an official language server's index — clangd (LLVM) for C/C++, a Roslyn-based LSP (Microsoft.CodeAnalysis.LanguageServer, the engine Visual Studio / the C# Dev Kit use) for C#/.NET — instead of Bash grep, and caps the tokens a search flood can spend by returning a compact file:line list (never source bodies). It's built for large Unreal C++ and .NET/C# codebases, where grep is slow and burns context.

It is the IDE-agnostic sibling of rider-mcp-enforcer: same token-efficiency goal, but instead of proxying a running IDE's MCP server, it spawns the official language server headlessly — so it works with Visual Studio / any C++/C# project without an editor open.

Marketplace — two plugins

This repo is a Claude Code plugin marketplace. It holds two plugins built around the same goal: read big things without paying for all of it in tokens.

Plugin	Does	Needs
vs-token-safer (this page)	Force code search through clangd/Roslyn's index over Bash grep (hard-block by default, escape hatch opt-out), token-capped to file:line	Node + a language server (clangd / Roslyn). No IDE.
gamedev-log-analyzer	Parse/dedup/classify huge Unreal/Unity/Godot/MSVC-UBT-MSBuild logs (CLI-first), search + diff + locate + extract scalars	Node only (no IDE)
