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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. While 'Fetches' implies a read-only operation, the description does not explicitly confirm safety, idempotency, potential error states, or whether this operation is expensive/computationally heavy.

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, efficient sentence with no filler words. It is appropriately front-loaded with the action verb. However, given the lack of schema documentation and annotations, this brevity results in under-specification rather than optimal clarity.

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?

While the presence of an output schema excuses the description from detailing return values, the complete absence of documentation for the required 'pid' parameter (in both schema and description) creates a critical gap for a tool that appears to target a specific instance via that identifier.

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?

With 0% schema description coverage for the required 'pid' parameter, the description must compensate but fails to mention the parameter entirely. It does not explain what 'pid' represents (process ID, plugin ID, etc.) or provide an example, leaving the parameter semantics undocumented.

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 uses a specific verb ('Fetches') and identifies the exact resource ('full UI structure') and components ('ButtonsModules and ScriptButtons'). However, it does not explicitly differentiate from the sibling tool 'get_buttons_data', which could cause confusion about which retrieval tool to use.

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 use this tool versus alternatives (e.g., 'get_buttons_data'), no mention of prerequisites for the 'pid' parameter, and no indication of when this call is necessary versus cached or static layouts.

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