wordpress_regenerate_thumbnails

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

With no annotations, the description carries full burden. It only says 'regenerate', implying a write/mutation operation, but lacks details on whether original images are affected, performance impact, or required permissions. Minimal disclosure beyond 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 short sentence, front-loaded with the key verb. It is concise but arguably under-specified given the lack of parameters and annotations. Every word earns its place, but more detail would be beneficial.

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 no schema parameters, no output schema, no annotations, and siblings that perform related tasks, the description is severely incomplete. It does not explain how to select specific images, what the output is, or any behavioral details. For a tool likely requiring user input, this is inadequate.

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 no parameters, yet the description mentions 'for all or specific images', implying some form of targeting. Since schema coverage is 100%, no parameter info exists to explain this. The description adds information that cannot be used, creating confusion and reducing semantic value.

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 (regenerate), resource (image thumbnails), and scope (all or specific images). It distinguishes from siblings like wordpress_bulk_optimize_images and wordpress_convert_to_webp by focusing on regeneration. However, it does not explain how 'specific images' are targeted, which is a minor gap.

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, no prerequisites, side effects, or exclusions. It simply states what it does without context for decision-making.

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