Each tool has a clearly distinct purpose with no significant overlap. Drawing tools (draw_circle, draw_line, draw_pixel, draw_pixels, draw_rectangle, fill_area) target specific shapes, while project management (create_project, delete_project, list_projects), layer/frame operations (add_layer, remove_layer, add_frame, duplicate_frame, remove_frame, clear_frame), and export functions (export_gif, export_png, export_sprite_sheet) are well-separated. The data retrieval tools (get_frame_data, get_pixel, get_project_info) also serve unique roles.

Tool names follow a consistent verb_noun pattern throughout, using snake_case exclusively. All names clearly indicate the action (add, create, delete, draw, duplicate, erase, export, get, list, remove) followed by the target object, making them predictable and readable. There are no deviations in naming conventions.

With 22 tools, the count is slightly high but reasonable for a pixel art editor covering project management, drawing, layer/frame manipulation, export, and data retrieval. It feels comprehensive rather than bloated, though it borders on the upper limit of typical scoping (3-15 tools). Each tool appears to earn its place without obvious redundancy.

The tool set provides complete coverage for a pixel art editor domain. It includes project CRUD (create, delete, list, get info), drawing operations (various shapes and tools), layer and frame management (add, remove, duplicate, clear), export formats (GIF, PNG, sprite sheet), and data access (pixel and frame data). There are no apparent gaps that would hinder agent workflows for core pixel art creation and editing tasks.
