Scored across 6 tools
Each tool has a distinct purpose: listing, opening, closing, configuring, reading, and writing serial ports. There is no overlap or ambiguity between them.
All tools follow a consistent verb_noun pattern in snake_case (e.g., close_port, get_port_config). The naming is predictable and clear.
Six tools cover the essential operations for serial port management without being excessive. The count is well-scoped for the domain.
Core lifecycle operations are present (list, open, close, read, write, get config). A minor gap is the lack of a set_config tool for modifying port settings, but agents can work around this.
