Install a sticker set

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

Annotations already provide openWorldHint and idempotentHint, which convey side-effect potential and idempotent behavior. The description adds no additional behavioral context beyond the surface action 'Install', so it meets the baseline but does not enrich transparency further.

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, focused sentence with no filler. It is front-loaded with the action and includes a useful example, making it optimally concise.

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 three parameters and no schema descriptions, the description covers only the required parameter and omits the optional ones. There is also no mention of return values or behavior, which is significant since no output schema exists. The description is too sparse to fully guide an agent.

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 schema has 0% description coverage, so the description must compensate. It explains 'shortName' with an example, but leaves 'archived' and 'accountId' completely unexplained. This is only partial compensation for the missing schema descriptions.

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 identifies the action ('Install') and the resource ('sticker set'), with a concrete example of the short name parameter. It is specific and distinguishes this tool from other sticker-related sibling tools like get_my_stickers or add_recent_sticker by focusing on installation.

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 implies when to use the tool (when you want to install a sticker set by short name) but provides no explicit guidance on alternatives or exclusions. It does not mention any prerequisite or context, so the usage context is only implicitly derived from the action.

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