draw_circle_at

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description fully needs to disclose behavioral traits such as side effects, creation behavior (create_if_missing), or overwrite behavior, but it provides none. It only repeats the basic action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence and very concise, but it is under-specified. Important information is missing, so conciseness trades off completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 9 parameters (6 required), no output schema, and no annotations, the description is severely lacking. It does not cover the most critical aspects: coordinates, color, fill, or layer/frame creation behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate by explaining key parameters. It does not mention center_x, center_y, radius, color, fill, or create_if_missing, leaving the agent to infer from names, which may be ambiguous.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Draw), resource (a circle), and context (on a specific layer/frame). The name 'draw_circle_at' reinforces targeting a specific location, distinguishing it from sibling 'draw_circle' which likely draws without specifying location.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'draw_circle' or 'draw_ellipse_at'. There is no mention of prerequisites, edge cases, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
