Each tool has a clearly distinct purpose: capture_element targets specific webpage elements, capture_screenshot handles full-page captures with advanced options, and list_device_presets deals with device configurations. There is no overlap or ambiguity between these functions.

The naming follows a consistent verb_noun pattern (capture_element, capture_screenshot, list_device_presets), with all tools using snake_case. The minor deviation is that list_device_presets uses 'list' instead of 'capture', but this is appropriate for its distinct function.

With only 3 tools, the count feels thin for a screenshot domain that might benefit from additional operations like managing screenshots or adjusting capture settings. However, it covers core capture functions adequately.

The toolset covers basic screenshot capture (element and full-page) and device preset listing, but lacks operations for managing captured screenshots (e.g., save, delete, annotate) or advanced configuration beyond presets. This creates minor gaps in the workflow.
