gimp_open_image

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

The annotation readOnlyHint=false already signals that this call mutates state, and the description adds that it 'returns info'. However, it does not explain the key behavioral trait beyond annotations: that opening loads the file into GIMP as the active image, nor what 'info' contains. With annotations covering the safety profile, a 3 is appropriate.

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 front-loaded sentence with no waste; the format enumeration is the one piece of added information and is placed inline rather than padding.

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 output schema, the description's claim to 'return info' is the only pointer to return values, and it is undefined. For a one-parameter tool with minimal annotations this is minimally adequate but leaves an agent guessing about the response payload.

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 carry the path parameter's meaning. Listing the supported extensions does add value about acceptable formats, but it never clarifies whether path is absolute/relative or how it interacts with GIMP's file handling, so it only partially compensates.

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?

States a specific verb (abre/opens) and resource (archivo de imagen) and enumerates the supported formats, which is concrete and helps an agent recognize the operation. It does not explicitly distinguish itself from siblings like gimp_new_image, gimp_image_info, or gimp_add_layer_from_file, so differentiation is only implied.

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 guidance on when to choose this tool over gimp_new_image (create), gimp_add_layer_from_file (add to existing), or gimp_image_info (query). The supported-format list hints at scope but no prerequisites, alternatives, or exclusions are stated.

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