Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| canvas_newA | 创建/重置一个空白画布 |
| draw_boxA | 在画布上绘制一个矩形框。x/y 是左上角坐标，w/h 是宽高（字符单位）。label 可选，显示在顶边框中央。 |
| draw_lineA | 在两点之间绘制一条折线（先水平后垂直） |
| draw_arrowA | 在两点之间绘制带箭头的连线，箭头指向终点 |
| add_textB | 在指定坐标添加文字（支持 \n 换行） |
| canvas_exportA | 导出当前画布为 ASCII 文本 |
| canvas_previewA | 预览当前画布状态（与 canvas_export 相同，用于中间检查） |
| canvas_batchA | 批量执行绘图指令并返回最终 ASCII 结果。ops 是指令数组，每条指令包含 op 字段指定操作类型（canvas_new / draw_box / draw_line / draw_arrow / add_text），以及对应参数。执行完所有指令后自动导出画布。 |

TDQS
Scored across 8 tools
Most tools target distinct drawing operations (draw_line, draw_box, draw_arrow, add_text) or canvas lifecycle (new, export, batch). However, canvas_export and canvas_preview are explicitly described as identical, which creates a potential selection ambiguity.
All tool names use lowercase snake_case and are readable. Drawing operations follow verb_noun (draw_line, draw_box, add_text), while canvas operations follow noun_verb (canvas_export, canvas_new). The two subgroups are internally consistent, but the mixed ordering is a minor deviation.
Eight tools is well within the ideal 3-15 range and covers the core needs of creating and exporting ASCII diagrams without excess. Each tool serves a clear purpose in the drawing workflow.
The tool set covers the full lifecycle: creating a canvas, adding text, drawing lines/boxes/arrows, previewing, batch execution, and exporting. No obvious dead ends or missing core operations for the domain.
