  4 |  * INDUSTRY PURPOSE: Addresses semantic gaps in vector-based tool discovery through
  5 |  * two complementary enhancement mechanisms:
  6 |  *
  7 |  * 1. CAPABILITY INFERENCE SYSTEM (Global Domain Knowledge)
  8 |  *    - Infers implicit capabilities from tool categories/types
  9 |  *    - Example: shell MCP → can perform git, docker, ffmpeg operations
 10 |  *    - Fills knowledge gaps that vector similarity cannot capture
 11 |  *
 12 |  * 2. SEMANTIC INTENT RESOLUTION (Context-Specific Language Mapping)
 13 |  *    - Maps natural language expressions to domain-specific operations
 14 |  *    - Example: "upload my code" → git:push, github:create_repository
 15 |  *    - Resolves contextual language that differs from tool naming
 16 |  *
 17 |  * This follows established NLP/IR patterns for query expansion and semantic matching.
