get_sticker_set

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description does not contradict them. However, it adds no behavioral context beyond the annotations, such as what happens if the sticker set does not exist or how the result is returned.

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 that front-loads the action and resource. There is no unnecessary information, making it highly concise and easy to parse.

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?

For such a simple tool with one parameter and rich annotations, the description is complete enough. It clearly states what the tool does and how the parameter is used, though it does not describe the return value or error handling, which is not critical for a basic getter.

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%, but the description explicitly states the set is retrieved 'by name', giving semantic meaning to the single parameter. This compensates for the lack of parameter documentation in the schema, though it does not elaborate on format or constraints.

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 ('Get') and the resource ('sticker set') with the method of identification ('by name'). It is specific and distinguishes itself from sibling tools like get_custom_emoji_stickers or delete_sticker_set.

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 tool's purpose is clear, but the description does not provide explicit guidance on when to use it over alternatives. No exclusions or alternative tool references are given, though the simplicity of the tool makes its usage fairly obvious.

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