install_sticker_set

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

Annotations already indicate non-read-only, non-destructive, and open-world behavior. The description adds one behavioral detail for the 'archived' parameter (adds to archived, not shown actively) but does not disclose other potential side effects, permission requirements, or what happens if the sticker set already exists. This provides some value beyond annotations but remains limited.

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 concise line stating the purpose, followed by a brief parameter explanation. Every word earns its place, with no redundancy or filler, making it highly efficient and front-loaded.

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 the simple two-parameter tool and the presence of an output schema, the description covers the core purpose and explains the non-obvious parameter. It doesn't mention prerequisites like authentication or the need to specify a sticker set's short name, but these are minor gaps for a straightforward install action.

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 description coverage is 0%, so the description must compensate for parameter meaning. It explains the 'archived' boolean well ('True — add to archived'), but the required 'short_name' parameter is not described at all, leaving its role ambiguous beyond the schema's title 'Short Name'. This partial compensation yields a moderate score.

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 'Install sticker set to account', identifying the verb, resource, and target. It distinguishes from siblings like uninstall_sticker_set and search_sticker_sets, though it doesn't elaborate on what 'install' entails beyond the archived parameter.

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 (e.g., get_installed_stickers, uninstall_sticker_set). It only states the basic action, leaving the agent to infer usage context without explicit exclusions or alternative recommendations.

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