photext_edit_text_in_image

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

No annotations are provided, so the description carries the full behavioral burden. The phrase 'Get the PhoText link' hints that the tool returns a link rather than mutating the image directly, but the description never states permissions, whether the original is preserved, or what the returned link contains. For a no-annotation tool this is a substantial gap.

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?

A single sentence with no filler, and the core action is front-loaded. It is efficient, though the 'Get the PhoText link' clause adds ambiguity rather than value.

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?

With no annotations, no output schema, and 0% parameter coverage, the description is too thin for a two-parameter tool. It omits what the returned link is for, how to use it, and how the two text parameters relate, leaving the agent under-informed.

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% and neither parameter is named or explained in the description. 'from_text' and 'to_text' are not self-evidently ordered or explained, and the description does not clarify what value belongs in each, so the description fails to compensate for the missing schema documentation.

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 states a specific action ('edit or replace text in an image while keeping the original font'), which distinguishes it from siblings like photext_remove_text and photext_translate_image by the nature of the operation. The opening 'Get the PhoText link' framing is slightly confusing, since it implies the tool returns a link rather than performing the edit, which muddies the purpose somewhat.

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?

There is no explicit when-to-use guidance, no prerequisites, and no named alternatives among the siblings. An agent must infer from the name alone whether this tool supersedes or complements photext_remove_text and photext_translate_image.

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