Scored across 13 tools
Every tool has a clearly distinct purpose with no ambiguity. The button press tools are all uniquely named for specific buttons, and the other tools handle distinct emulator operations like screen capture, ROM management, and frame control. There is no overlap in functionality.
All tools follow a consistent verb_noun pattern with snake_case throughout. The naming is perfectly predictable: 'get_screen', 'list_roms', 'load_rom', 'press_a', 'wait_frames', etc. There are no deviations in naming conventions.
13 tools is well-scoped for a GameBoy emulator server. Each tool earns its place with clear purposes: ROM management (3 tools), button controls (8 tools), screen capture (1 tool), and frame control (1 tool). This provides comprehensive coverage without bloat.
The tool surface is nearly complete for GameBoy emulation, covering ROM loading, button inputs, screen capture, and frame control. A minor gap exists in reset/unload functionality, but agents can work around this by reloading ROMs. Core emulator workflows are well-supported.
