Scored across 7 tools
Each tool has a clearly distinct purpose: enumerate ports, open/close connections, send command with prompt handling, write raw data, read buffered data, and list connections. No overlap between send_command and write_raw; they handle different interaction modes.
All tool names follow a consistent verb_noun snake_case pattern (e.g., list_ports, open_port, read_buffer). The convention is uniform and predictable.
Seven tools is well-scoped for a serial port server, covering essential operations without redundancy or bloat. Each tool earns its place.
The surface covers the full serial port lifecycle: enumeration, open/close, command/raw writing, buffered reading, and connection monitoring. No obvious gaps for typical serial interaction workflows.
