wordpress_bulk_optimize_images

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

With no annotations, the description must disclose behavioral traits. It states 'compress all images' implying a write/mutation operation, but does not explain whether it creates backups, whether the operation is reversible, or if it runs asynchronously. The tool's impact on image quality, disk usage, or performance is also unaddressed.

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, clear sentence: 'Bulk optimize images (compress all images)'. It is tightly focused, contains no fluff, and front-loads the core action. Every word earns its place, achieving maximum conciseness.

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 zero parameters and no output schema, the description is minimally adequate but leaves ambiguity about the scope: 'all images' could mean all images in the media library, all image sizes, or all images on the site. It also does not confirm success indicators or potential side effects. A more complete description would specify the exact scope and typical effect.

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?

The input schema has zero parameters, so schema description coverage is effectively 100%. Since there are no parameters to document, the description does not need to add parameter details. The baseline of 4 is appropriate, as the description does not mislead but adds no extra value beyond the schema.

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 'Bulk optimize images (compress all images)', specifying the action (optimize/compress) and resource (images). It is distinguishable from sibling tools like wordpress_convert_to_webp, which converts images to WebP format, and wordpress_regenerate_thumbnails, which regenerates thumbnail sizes. This covers the core purpose unambiguously.

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?

The description provides no guidance on when to use this tool versus alternatives like wordpress_convert_to_webp or wordpress_regenerate_thumbnails. It does not specify prerequisites, typical use cases, or scenarios to avoid. The absence of context leaves the agent to infer usage from the name alone.

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