lemonade_buy_upgrade

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

With no annotations, the description carries the full burden. It discloses 'permanent' but omits critical side effects such as cost deduction, inventory changes, or one-time applicability. It does not clarify that this is a state-changing 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, efficient sentence with no wasted words. It is appropriately front-loaded but lacks detail, which is acceptable for a simple buy action, though it could be slightly more informative.

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 tool has no output schema and no annotations, the description is too terse. It fails to specify how to obtain valid upgrade names, what happens after purchase, or the economic impact, making it incomplete for safe invocation.

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 description adds 'named' to indicate the upgrade parameter should be a specific identifier, and the schema provides an enum of possible values. However, with 0% schema description coverage, it does not explain what each upgrade does or where to find the list, making the parameter only marginally clearer.

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 (buy) and the object (permanent stand upgrade), using specific domain terminology. It is distinguishable from sibling tools like lemonade_buy_supplies by explicitly targeting upgrades.

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?

No guidance is provided on when to use this tool, prerequisites, or alternatives. It does not mention the upgrade catalog (lemonade_get_upgrade_catalog) or any conditions like available funds or location, leaving the agent without usage context.

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