Add a text frame to the active document

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

Does not disclose return value, side effects, error handling, or whether it modifies the active document. Minimal behavioral info.

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?

One concise sentence, no fluff, but lacks detail. Structure is simple and clear.

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 the schema has only minimal descriptions, the tool description does not fill gaps like output, errors, or context. Incomplete for a robust tool.

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?

Only fillColor has schema description; x, y, text, fontSize lack explanation. Description mentions position but not units or coordinate system. Lacks detail on meaning of parameters.

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?

Clearly states it adds a point-text frame with given content, position, font size, and color to the active document. Distinguishes from shape-adding tools.

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 on when to use this tool versus others, or any preconditions. Does not mention coordinate system or any requirements.

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