Why context limits matter for LevelDB

LevelDB is a foundational C++ codebase, heavily utilizing templates and intricate testing suites. Files like db/db_test.cc and db/version_set.cc take up substantial context space with deep implementation details. By stripping these C++ method bodies, mcp-injector reduces the context footprint by 55.5% while preserving class hierarchies.

Reproduce this benchmark

You can verify these numbers yourself using the open-source mcp-benchmark tool:
