Name	Description
draw_image_to_fileA	Draws a picture with pillow and saves the resulting image to a file. output_path: absolute file path to save to; the image format is inferred from the extension (e.g. .png, .jpg). Parent directories are NOT created. width: canvas width in pixels (positive integer). height: canvas height in pixels (positive integer). commands: list of drawing commands, executed in order; each command is a JSON object with a "shape" field selecting one of: line, rect, circle, ellipse, triangle. Supported shapes and their fields: line: "shape": "line", fields: start (x, y), end (x, y), color (default black), width (default 1) rect: "shape": "rect", fields: box (left, top, right, bottom), fill (default black, None for none), outline (default None), width (default 1) circle: "shape": "circle", fields: center (x, y), radius, fill (default black, None for none), outline (default None), width (default 1) ellipse: "shape": "ellipse", fields: box (x0, y0, x1, y1), fill (default black, None for none), outline (default None), width (default 1) triangle: "shape": "triangle", fields: points (three (x, y) vertices), fill (default black, None for none), outline (default None), width (default 1) Commands are validated individually. Invalid commands are skipped, and a warning listing them (1-based positions) is included in the result; the image still contains all valid commands in order. If no command is valid, the call fails with a listing of the per-command errors. Coordinate system: The coordinate system has its origin at the top-left corner; x increases to the right, y increases downward. All coordinates are in pixels on a fixed-size white background canvas; drawing outside the canvas bounds is clipped (harmless). Commands run in list order, and later commands overpaint earlier ones. Color format: Color as a CSS color name (e.g. 'red', 'darkorange') or hex code (e.g. '#8b4513'). Values are passed through to Pillow. Paint semantics: fill=None gives an unfilled shape; outline draws the border; width is the stroke width in pixels for line/rect/circle/ellipse/triangle. Example (200x200 canvas): { "output_path": "/home/myuser/documents/picture.png", "width": 200, "height": 200, "commands": [ {"shape": "circle", "center": [100, 80], "radius": 50, "fill": "gold", "outline": "orange", "width": 3}, {"shape": "triangle", "points": [[50, 170], [150, 170], [100, 70]], "fill": "darkgreen"}, {"shape": "line", "start": [20, 185], "end": [180, 185], "color": "black", "width": 2} ] }
draw_imageA	Draws a picture with pillow and returns the resulting image as inline PNG image content.

A4.6/5.0

Scored 2026-08-27 12:20 across 2 tools

Disambiguation5/5

The two tools split cleanly by output destination: draw_image_to_file persists to disk, while draw_image returns inline PNG content. Their names and the presence of output_path only in the file variant make misselection unlikely.

Naming Consistency5/5

Both tools follow the same draw_image verb-object prefix, with the file-save variant adding the clear _to_file suffix. The naming is snake_case and consistent across the whole set.

Tool Count4/5

Two tools is slightly below the typical 3-15 range, but the count is reasonable for a narrow painter: one output mode is file saving and the other is inline PNG. It feels minimal rather than excessive.

Completeness4/5

The core draw-and-output workflow is fully covered: all five shapes, validation, coordinate handling, and both file and inline delivery are present. Minor gaps remain, such as only having a fixed white background and no text or image-import tools, though these are workaround-able or outside the narrow scope.
